Project Connect’s Orange Line operating cost assumptions seem to fail plausibility test

3 December 2019

This analysis has been adapted and revised from comments originally posted to the #ATXTransit listserv by Lyndon Henry, a technical consultant to the Light Rail Now Project and contributing editor to Austin Rail Now (ARN).

For approximately the past year, Capital Metro’s planning program, Project Connect, has been analyzing two travel corridors for major high-capacity rapid transit investment – the Orange Line (basically following the North Lamar-Guadalupe-South Congress corridor) and the Blue Line (roughly following the Red River-San Jacinto/Trinity corridor through downtown and then the Riverside corridor out to ABIA). A federally required Alternatives Analysis has been undertaken by a consulting team led by AECOM to recommend a modal system choice between light rail transit (LRT) and bus rapid transit (BRT), as well as other features and service characteristics such as vehicle types, station locations, alignments, and the capital costs and operating and maintenance (O&M) costs of each alternative.

Recently the agency released as public information selected details, including methodological procedures and cost assumptions. These have prompted scrutiny by community professionals and activists, particularly in regard to important O&M cost assumptions. In some cases these assumptions have been called into question.

For example, a 13 November posting by research analyst Julio Gonzalez Altamirano (JGA) on his Informatx.org website presented an extensive critical analysis. This resulted in two major findings:

• Project Connect’s BRT revenue hour cost estimate is lower than the national average by 26%. Project Connect does not explain its rationale for the methodological choices that lead to the lower rate.

• Project Connect’s use of a flat passenger car revenue hour rate to calculate LRT costs obfuscates the economies of scale associated with multi-car LRT trains. This is a change from the approach taken by Project Connect in 2013-2014. The new method makes Blue Line LRT appear more productive and Orange Line LRT less productive than an approach that recognizes the cost advantages of LRT scale (e.g. multi-car trains). Project Connect does not explain the rationale for the methodological switch or why its current approach will generate more accurate estimates.

These findings are broadly in line with the results of ARN’s own research into Project Connect’s O&M cost methodology and resultant assumptions, particularly with respect to the Orange Line surface LRT and BRT alternatives. Our analysis relied primarily on data for appropriate peer systems to Austin, reported in the Federal Transit Administration’s National Transit Database (NTD).

Basically, we find that Project Connect’s cost per vehicle-hour assumptions consistently seem to overestimate LRT costs by more than 51% and underestimate BRT costs by over 26%. The bottom-line result is to skew Project Connect’s O&M cost assumptions as much as 70% in favor of the BRT alternative. This produces a relatively huge disparity in evaluating the alternatives, and challenges plausibility. Details of our analysis, plus conclusions and a recommendation, are presented below.

Methodology

Operational configurations and service cycles affect O&M costs, including costs per vehicle-mile. ARN’s methodology has differed somewhat from JGA’s. Most importantly, from the 2017 NTD (latest currently available), ARN selected seven new-start LRT “peer” systems based on both urban characteristics and surface-running alignment and operational configurations that we judged to more closely match those of Austin and the proposed Orange Line surface LRT: Denver, Houston, Minneapolis, Phoenix, Portland, Sacramento, Salt Lake City. Although some have urban or suburban branches on exclusive alignments, all have significant segments in urban streets.

These seven systems have been selected in part for their urban, extensively on-surface, and in some cases predominantly street-routed character (similar to the alignment proposed for Austin’s Orange Line). Generally comparable urban population and density were also an important factor. As state capitals, Denver, Sacramento, Phoenix, Salt Lake City, and St. Paul (included in the Minneapolis-St. Paul system) also make good peer cities for Austin. Other new-start LRT systems that might have some sections on city streets but operate predominantly over extensive regional lines or grade-separated alignments were not considered as fully comparable cost models.

In contrast to our peer-systems approach, Project Connect states that, via its own methodology, “O&M unit costs for LRT service reflect a weighted national average cost per revenue hour ….” [Orange Line Operating and Maintenance Costs, 30 Oct. 2019] Apparently these costs are based on NTD data.

However, if Project Connect calculated its average from national data of all LRT systems reported in the NTD, this would have included a widely disparate collection of O&M and other data, much of it starkly dissimilar to Austin’s demographics and proposed LRT operational conditions. For example, legacy systems (remnants of historic surface electric railways dating back to the late 19th or early 20th century) such as those in Boston, San Francisco, Newark, and Pittsburgh retain a variety of older operating characteristics (e.g., onboard fare collection by train operators) that drive their vehicle-hour costs significantly higher than the average of modern new-start systems.

Other problems with such an indiscriminate approach include differences in alignment engineering configuration. Accordingly, we assessed some modern new-start LRT systems to be less suitable O&M vehicle-hour cost models for Austin’s proposed street-routed LRT Orange Line, including several we excluded particularly because of their proportionately more extensive subway and elevated segments: Buffalo, Los Angeles, St. Louis, Dallas, Seattle.

Nevertheless, despite what appear to be serious weaknesses with its own methodological assumptions, Project Connect has calculated an O&M cost per vehicle-hour of $284.15 (2017) for its Orange Line LRT surface alternative.

As regards BRT, in our judgement eight of the operational configurations of BRT systems reported in the 2017 NTD seemed to conform to the Orange Line BRT surface operating proposal, and can be assumed to represent peer systems with respect to Austin. These BRT services – operating in Cleveland, Eugene, Ft. Collins, Grand Rapids, Hartford, Kansas City, Los Angeles, and Orlando – thus provide an appropriate basis for comparing and evaluating Project Connect’s Orange Line LRT and BRT scenarios. New York City was excluded because its exceptionally high density, population size, and vast multi-model transit system are far out of proportion to Austin’s conditions. Boston’s disconnected system, partly operating as a trolleybus subway, also seemed inappropriate as a peer system. Likewise the Roaring Fork Transportation Authority’s operation, a basically rural system more closely resembling a regional or intercity motor coach service than an urban transit service, was also excluded. Data for the eight peer systems were used to develop metrics for comparison with Project Connect’s assumed cost inputs.

For 2017 O&M cost per vehicle-hour for Project Connect’s Orange Line BRT surface alternative, Project Connect’s own assumptions (based on information from CMTA and NTD) amount to an effective estimate of $119.10, as JGA has converted from Project Connect’s 2028 estimates.

To calculate current national averages and metrics for comparison, we’ve totaled current costs and other relevant values for the target LRT and BRT peer groups from National Transit Database (NTD) profile data, then calculated averages from those totals. All costs discussed are presented in 2017 dollars.

Results

LRT: Average actual 2017 O&M cost per vehicle-hour for the seven peer LRT systems is $187.52, 34.0% lower than Project Connect’s assumed cost of $284.15 for the Orange Line surface LRT option.

BRT: Average actual 2017 O&M cost per vehicle hour for the eight peer BRT systems is $162.23, 36.2% higher than Project Connect’s assumed cost estimate of $119.10 for the Orange Line surface BRT option.

LRT vehicle-costs/hour are typically higher than for buses mainly because LRT cars are larger and stations are also usually larger, creating higher maintenance costs. (These characteristics generally stem from LRT’s higher capacity and propensity to attract greater passenger volumes.) The ratio of actual NTD-reported peer-system LRT to BRT costs is 1.16. However, Project Connect’s cost assumptions amount to an LRT:BRT ratio of 2.39 – in other words, approximately twice the cost ratio in actual operating experience. The disparity between Project Connect’s estimates and costs experienced in actual operations is illustrated in the graph below.


Graphic illustration of disparity between Project Connect’s O&M unit-cost estimates and actual reality of costs experienced by actual operations of comparable peer LRT and BRT systems. Graph: ARN. (Click to enlarge.)


Conclusions and recommendation

Project Connect’s assumption for cost per vehicle-hour appears to substantially underestimate BRT and overestimate LRT – and this has dramatic consequences for the agency’s overall cost model results, seemingly skewing the evaluatory process and calling into question the plausibility and validity of the agency’s O&M cost analysis. The table below, presenting Project Connect’s comprehensive O&M cost calculations for the Orange Line alternatives, illustrates how the differential in O&M cost-per-vehicle-hour estimates translate into enormous differences of tens of millions of dollars in annual O&M cost assumptions.

We would strongly recommend that these assumptions and the overall O&M analysis of these alternatives be reviewed and revised – particularly by basing cost estimates on appropriate peer systems relevant to the LRT and BRT alternatives proposed by Project Connect for the Orange Line.

Blue Line Should Branch from Orange Line Urban Rail — Nix the Redundant Infrastructure!

15 August 2019

Map shows ARN’s alternative proposed urban rail configuration in Core Area connecting Orange Line (Tech Ridge to Slaughter Lane) with Blue Line (UT campus through Core Area and East Riverside to ABIA). Both lines would share First St. (Drake) Bridge over river, thus eliminating need for an expensive redundant Blue Line bridge. Blue Line would branch from Orange Line at Dean Keaton and at W. 4th St. to serve east side of Core Area and provide link to airport. Map: ARN.

Commentary slightly adapted from one-page handout originally produced by ARN and distributed to participants in Project Connect’s Blue Line Workshop at ACC Highland, 31 July 2019.

► Orange Line as primary corridor — Urban rail installation in the Orange Line alignment (N. Lamar-Guadalupe-Lamar-South Congress/NL-G-SC) must be prioritized. Positioned as Austin’s major central local corridor, between I-35 to the east and Loop 1 (MoPac) to the west, the Orange Line corridor is the center city’s 3rd-heaviest north-south travel corridor (after I-35 and MoPac). The City of Austin has repeatedly emphasized that this is the primary local traffic corridor in central-city Austin, with exceptionally heavy traffic at maximum capacity for over the past 2 decades. North Lamar alone is ranked by Texas Transportation Institute as one of the most congested arterials in Texas. With Austin’s highest total employment density on Guadalupe-Lamar, an urban rail line there alone could serve 31% of all Austin jobs. It would also serve the highest-density residential concentrations in the city — including the West Campus, ranking the 3rd-highest in residential neighborhood density among major Texas cities.

► Light rail transit (LRT) — For over 30 years, urban rail in the NL-G-SC (currently designated Orange Line) alignment has been regarded as the key central spine for an eventual citywide and regional urban rail network using well-proven, widely deployed, effective, affordable light rail transit (LRT) technology. Particularly with little to no need for major civil works, the Orange Line is ideal for a surface-installed LRT starter line.

Since initially selected as Capital Metro’s Locally Preferred Alternative in 1989, LRT has remained Austin’s premier major high-capacity transit vision. LRT has demonstrated numerous key advantages over bus rapid transit (BRT). And unlike many “gadget” alternatives, LRT is well-proven in service, a readily available technology, and non-proprietary. (In contrast, “autonomous BRT” has been neither deployed commercially nor even tested.) Compared with buses, LRT systems provide higher capacity and are faster, more user-friendly and more comfortable to access and ride. On average, ridership on new LRT systems is 127% higher than on BRT. LRT is also more cost-effective – average operating cost of new LRT systems is 10% lower than for BRT.

► Alternate Blue Line — Simply trying to resurrect the failed 2014 Highland-Riverside plan is not a prudent option. The Blue Line makes the most sense if it shares segments of the Orange Line, branching from it to serve the eastside of the Core Area and UT, and the East Riverside corridor (and ultimately ABIA). Running westward from ABIA on East Riverside, the Blue Line in this proposal would join the Orange Line south of the S.1st St. (Drake) Bridge. Sharing trackage across the bridge, it would proceed northward to Republic Square, where it would turn east to the San Jacinto/Trinity arterial pair, then turn northward and proceed to serve the Medical District and the UT East Campus. At Dean Keaton, the alignment would then turn west and travel on Dean Keaton toward Guadalupe St. to rejoin the Orange Line, proceeding northward from there. Access to-from ACC Highland could be made available via transfer with Red Line trains (with improved frequency) or various bus alternatives (from UT campus or Crestview).

► Eliminate redundant infrastructure — Major advantages of this alternative include more efficient operation, better passenger interconnection between Blue and Orange Lines, and very significant cost savings through eliminating redundancy: the proposed bridge over the Colorado, approximately three miles of line infrastructure paralleling the Orange Line, and five stations.

Road and rubber-tire transport plans thwarting urban rail? Seems to fit a pattern

30 January 2019

Construction of U.S. 183 South expressway. Source: Fluor..

As previous posts on this website have noted, for about 28 years – from 1989, when light rail transit (LRT) was identified by Capital Metro as the region’s Locally Preferred Alternative for its Major Investment public transport mode, until the first quarter of 2018 – urban rail held a central and absolutely key role in Austin-area mass transit planning, memorably exemplified by the “Rail or Fail” slogan in 2014. But just as the Project Connect planning process, in early 2018, was rendering a new proposal for LRT after more than two additional years of research, public input, and analysis, that process was thwarted and reversed by a new Capital Metro administration in consort with several local officials, all focused on rubber-tired, roadway/highway-based, and sprawl-driving alternatives to rail.

The reasons for this 180-degree change in policy remain somewhat obscure. But they do seem to fit a persistent pattern of trying to minimize public transport investments in order to divert local funding resources into major new roadway projects (such as a massive overhaul to I-35). This emphasis on vast new roadway investment has been documented in a series of our previous posts:

Basically attempting to reboot the “derailed” Project Connect planning process, Capital Metro has has just issued a solicitation for engineering/planning services, to include performance of an Alternative Analysis of transit mode options. But this comes in the context of about seven months of aggressive top-level hyping of the supposed advantages of “bus rapid transit” (BRT) and a chimerical mode (currently “under development”) described as “autonomous rapid transit” (ART) – autonomous (robotic) buses theoretically capable of emulating the operation of LRT trains.

Capital Metro’s recent solicitation appears to focus on the proposed “Orange Line” corridor (basically the Tech Ridge-to-Slaughter Lane alignment that consists of the N. Lamar-Guadalupe and South Congress corridors), intended for implementation of “high-capacity transit” in “dedicated pathways”. Under pressure and criticism from various community leaders and Austin councilmembers, the solicitation specifies inclusion of “Dedicated Pathways Light Rail Transit (LRT)” in the mix of modes to be considered in the Alternatives Analysis.

Unfortunately, over many previous months several local officials favoring highways and buses have, in public statesments, claimed exaggerated costs for LRT and implied that this “high cost” makes such a system unaffordable for Austin. In occasionally similar major investment planning situations in other communities, it’s been suspected that key public officials have influenced their planning teams to skew “analysis” results toward their preferred results.

Light rail can have a broad range of costs and performance results depending on key design decisions and the competence of the planning team. Will evaluation of LRT be handled fairly in the forthcoming “high-capacity transit” study for the Orange Line corridor? Transit advocates would be well-advised to do their best to help ensure that it will be.

Let’s Fast-track a Plan for Urban Light Rail — and Make It Happen

by Lyndon Henry

This post is a publication of comments made by Lyndon Henry to the Austin City Council on 13 December 2018. Henry is a technical consultant to the Light Rail Now Project and a contributing editor to the Austin Rail Now website.

For decades, Austinites have been suffering the agonies of a worsening mobility crisis. Help has never been far away – over the past 30 years, no less than six official studies have come to the same conclusion: light rail transit, interconnected with an extensive bus network, is what’s needed.

But time after time, Austin’s leadership has failed to bring a single one of these plans to successful fruition. Austin has become the national poster child of analysis paralysis.

And now Capital Metro and its Project Connect planning program have restarted us on another re-iteration of this same exhausting process for a seventh time and another two years.

Transit advocates appreciate that Capital Metro has revised its Vision concept by restoring light rail and some additional corridors. But much more is needed.

Instead of backsliding to zero again, Capital Metro and the City of Austin need to fast-track this process by building on the data, analysis, community input, and other resources that have already recommended a light rail system and enhanced bus network as the way out of our mobility quagmire.

The Vision plan needs to become a lot more visionary. It needs to preserve a lot more corridors for future dedicated transit lanes. It needs to envision more and longer routes reaching out to serve other parts of the urban area.

Light rail can make this possible. It’s an affordable, cost-effective, off-the-shelf electric transport mode that’s well-proven in hundreds of cities and, best of all, it’s here today – we don’t have to wait for some science fiction technology. Austin needs a solution that’s available now.

Urban light rail is the crucial linchpin of a mobility plan because it has the power to make the whole system work effectively. It’s shown it has the true capacity to cost-effectively handle and grow Austin’s heaviest trunk routes, freeing up buses and resources to expand service into many more neighborhoods citywide. This advantage is validated by solid evidence – in average ridership and cost-effectiveness, cities with urban rail have significantly outpaced cities offering bus service only.

Yet even before Study No. 7 has begun, some Capital Metro and other local officials have been hinting they favor bus rapid transit (BRT) – basically a repackaging of bus service with minimalist capital improvements and lots of fanfare. But it’s unlikely BRT will provide the breakthrough Austin so desperately needs.

On average, compared to BRT, new light rail systems are carrying over three times the ridership at 10% lower operating cost. They’ve shown they can spark adjacent economic development and help shape urban density and growth patterns. BRT has shown almost no such benefits. And light rail comes without the toxic pollution and other problems of rubber tires.

Let’s leave the paralysis behind, and put a light rail starter line on a fast track for a vote in 2020.


An even more affordable light rail starter line project has been proposed by Central Austin Community Development Corporation as a 5.3-mile Minimum Operable System extending from the Crestview MetroRail station (at N. Lamar/Airport) to Republic Square. For a surface alignment with no major civil works, estimated cost in 2016 was less than $400 million. Graphic: CACDC.

Reinstate Urban Rail in Austin’s Planning

19 September 2018

Project Connect slide illustrating “Autonomous Rapid Transit” technology at joint Capital Metro/City of Austin work session Sep. 14th represents currently hypothetical, undeveloped technology as question mark, yet proposes it for inclusion in new “Vision Plan”. Meanwhile, plan with proven, available modes including light rail transit (LRT), presented in February 2018, has been withdrawn. Graphic: Project Connect.

by Lyndon Henry

This post is a publication of comments made by Lyndon Henry to a public hearing held by the board of directors of Capital Metropolitan Transportation Authority on 17 September 2018. (The remarks refer to a “presentation this past Friday” – made by Capital Metro’s Project Connect planning team to a Joint Capital Metro Board/City of Austin City Council Work Session on Friday 14 September.) Henry is a technical consultant to the Light Rail Now Project and a contributing editor to the Austin Rail Now website.

I’m Lyndon Henry, a transportation planning consultant, former Capital Metro Board member, and currently a writer for Railway Age magazine.

Seven months ago, Project Connect at last presented a viable, attractive public transport plan, centered on a central light rail line from Tech Ridge to Slaughter Lane that would connect the city’s heaviest local travel corridors – Lamar-Guadalupe and South Congress. It was a plan that won substantial acclaim from the community and reflected what was already supported in public surveys.


Left: Project Connect draft system plan (presented in Feb. 2018) proposed multiple bus and rail routes, including long north-south light rail line (shown in purple north of the river and lavender to the south) stretching from Tech Ridge to Slaughter Lane. Right: Initial phase of LRT project (proposed Feb. 2018) would run from Tech Ridge to downtown at Republic Square, mainly following the North Lamar-Guadalupe corridor. Maps: Project Connect. (Click to enlarge.)


Astoundingly, within a month that plan was taken off the table, and apparently discarded. To judge from the presentation this past Friday, that realistic, workable plan has now been replaced by a question mark – literally. While Austin is facing a painful and mounting mobility crisis, we’re now informed that official planning is expunging rail from consideration, and has been re-focused on a buses-only operation predicated on visions of a totally untested, effectively imaginary technology (identified with a question mark in presentation slides).

This recent abrupt about-face in the direction of Austin’s public transport planning is extremely bad news – for urban public transport and the future mobility and livability of this entire metro area. Besides the trashing of the orderly planning process, the implications for Austin’s public transport are potentially far more seriously damaging.


Slide from Feb. 14th Project Connect presentation shows hypothetical “Autonomous Rapid Transit (ART)” as question mark. Since mode is currently imaginary, characteristics and performance claims for it in chart are apparently based on pure speculation. Does a currently fictional technology merit inclusion in a presentation of critical public transport options? Graphic: Project Connect.


It says a lot that, since the late 1970s, at least 19 North American cities have opened brand-new light rail systems, almost every one of which has decisively reversed previously declining ridership, increased public attraction to transit, improved urban livability, sparked economic development, and attracted real estate development to cluster near the rail stations. In contrast, the results for the handful of new BRT [bus rapid transit] and quasi-BRT operations have been spotty, and at best a pale shadow of light rail’s success.

In Austin, over the past 28 years, at least three multimillion-dollar publicly sponsored comparative studies have selected light rail as the superior mode to BRT, particularly in key features such as capacity, cost, and various community impacts.

While new technology can improve transit, it must be rigorously tested and proven. But in terms of demonstrated workability and performance, the latest “transit vision” of “a regional system of autonomous, electric-powered buses moving in platoons” is little more than a fantasy, and quite possibly a fraud. Four years ago, the Project Connect team rejected reliance on “Newer technology that does not have proven application”, and warned that “Unproven technologies have unforeseen costs”. Now those caveats have disappeared, replaced by assurances and hype.


Project Connect chart from 2014 includes warnings (annotated with red arrow) against “Unproven technologies”. Graphic: Project Connect.


But what proponents seem to be actually committing Austin to, in reality, is BRT for the region’s major “high-capacity” transit system. The idea seems to be to place all our hopes on an unproven hypothetical technology that will emerge – and be satisfied with BRT in the meantime.

Yet while the Austin region’s mobility crisis continues to worsen as I speak, light rail is available now, a well-proven mode with a long record of success. It’s out-performed BRT and proven far more affordable than subway-elevated alternatives. I urge you to reinstate that February plan with a central light rail spine so Austin can continue to move forward with a real-world solution to our mobility crisis.

Thank you for the opportunity to put these observations and warnings in the public record.

Why “Super BRT” in I-35 would betray Capital Metro’s member cities

31 October 2017

Project Connect rendition illustrates how “SuperBRT” might use high-occupancy toll (HOT) lanes alongside a highway such as I-35. But where are the stations? Graphic: CMTA online.

Commentary by Dave Dobbs

Dave Dobbs is publisher of LightRailNow.com. This commentary has been adapted and expanded from original private Email comments.

This website’s recent articles «Officials boost roads and “Super BRT”, put urban rail on side track» (Aug. 31) and «Why TxDOT-Capital Metro ‘BRT’ plan for I-35 is a massive boondoggle» (Oct. 1) explained how (under pressure from TxDOT) Capital Metro has been proposing to designate I-35 as Austin’s primary transit corridor, and to install a 21-mile express bus facility (“Super BRT”) in what is to be an overhauled freeway-tollway. “Politically aware” members of Capital Metro’s board ought to understand that providing scarce Capital Metro dollars for this “Super BRT” project – designed mainly to serve non-member cities like Round Rock (voted not to join the transit agency in 1985) and Pflugerville (withdrew in 2000) – is a betrayal of the original sales-tax-paying members of Leander, Jonestown, Lago Vista, Point Venture, Anderson Mill, Volente, San Leanna and Manor, all of which (except Manor and San Leanna) are located northwest, on the US 183 corridor.

Most importantly, with over 95% of Capital Metro’s local tax revenues coming from Austin sale taxes, I-35 Super BRT is a very poor use of limited resources from the benefit principle perspective. This is bad public policy and bad public finance with a negative ROI.

Capital Metro board members, other local officials, Austin’s civic leadership, and the metro area public at large need to consider: What does expending scarce transit agency funds on “Super BRT” to run in I-35 – i.e., funding a transit facility that primarily benefits non-member citizens – say to Capital Metro’s taxpayers?

In contrast, a Guadalupe-Lamar corridor light rail connection to MetroRail at Crestview would be highly advantageous to those who pay the Capital Metropolitan Transportation Authority (CMTA) 1¢ sales tax. In lieu of this, where’s the benefit to the citizens of Austin and six of the eight member cities who’ve the sales taxes for CMTA transit service from the start?

This is a serious public finance question. Jonestown, Lago Vista, Leander, Point Venture, Volente, Anderson Mill and vast areas in Austin’s northwest ETJ are entitled to any major transit fixed quideway investment on a first-priority basis over entities who never were or aren’t now Capital Metro members. Spending Capital Metro money on an IH35 “busway” is a complete rejection of the Benefit Principle.

Why TxDOT-Capital Metro “BRT” plan for I-35 is a massive boondoggle

1 October 2017

Rendering of rebuilt I-35 at MLK Blvd. with HOT lanes for use by “Super BRT” (shown in purple and yellow). Graphic: TxDOT.

The leadership of Austin’s Capital Metropolitan Transportation Authority (CMTA, aka Capital Metro) seems to be rolling forward full-throttle to implement a dubiously described “bus rapid transit” (BRT) plan for Interstate Highway 35 pushed by by the Texas Department of Transportation (TxDOT) to bolster the highway agency’s massive over-$4 billion I-35 upgrade project. This mammoth project was the focus of a March 2016 posting on this website by Roger Baker and Dave Dobbs headlined «Why spending $4.7 billion trying to improve I-35 is a waste of money» (with the secondary headline «Trying to widen Austin’s most congested road will only make congestion worse»).

As that article warned,

TxDOT is far short of sufficient funds to widen I-35 with its own resources, having identified only $300 million in-house out of $4.5 billion needed. That leaves TxDOT $4.2 billion short — over 90% deficient. In fact, the Travis County section of TxDOT’s My35 redesign is still $1.8 to $2.1 billion short, which should raise red flags for local property owners who could well be targeted for big tax increases.

During this period, Capital Metro resuscitated Project Connect – its major planning effort ostensibly tasked with evaluating possible rail and other forms of “high-capacity transit” – to supposedly sift through various corridors, types of service, and alternative transit modes, and develop recommendations for a package of major new “high-capacity transit” investments. The process has been performed nominally with the oversight of the Multimodal Community Advisory Committee (MCAC).

Mysterious new “Super BRT” project appears

For a while the Project Connect study appeared to stay mostly on track, still focused on corridors, and just starting an evaluation of transit modes. But then it seemingly began to take a detour this past summer, when reports began to reveal TxDOT’s sudden interest in obtaining Capital Metro’s commitment to a very specific transit decision: a mysterious new “bus rapid transit” project on I-35, proposed to use High-Occupancy Toll (HOT) lanes planned for the huge reconstruction of the freeway. (See graphic rendering above.) In a June 27th article Austin Monitor reporter Caleb Pritchard noted some details about the BRT plan discussed at a Capital Metro board meeting the previous evening, including TxDOT’s efforts to muscle the transit agency “to fork over $123.5 million to cover the entire cost of the [bus project] transit infrastructure.” At this, reported Pritchard, Capital Metro had “balked”, but was negotiating with TxDOT on a “counter-offer” to “cough up approximately $18 million” toward such a project and to seek other agencies (such as the City of Austin) as partners.

According to the article, Capital Metro’s vice president of strategic planning and development, Todd Hemingson, revealed that the transit agency had “been talking with TxDOT for five years about the I-35 bus rapid transit plan.”

The department is planning a $4 billion overhaul of the highway and appears to be open to the agency’s insistence that the project include some dedicated allowance for transit. The formative vision for the bus rapid transit system includes a handful of stations built on bus-only lanes in the median of the interstate. Those stations, Hemingson said, would be paired with frequent-service bus routes on intersecting east-west corridors.

The initial ridership projects for the proposed route between Tech Ridge Boulevard in North Austin to State Highway 45 in South Austin is between 4,000 to 6,000 trips per day.

At the meeting, Multimodal Community Advisory Committee member Susan Somers (president of the AURA urban issues community group) “raised concerns about moves that appear to make a proposed bus rapid transit system on I-35 a predetermined outcome of the Project Connect process.”

TxDOT’s arm-twisting intensified. Within weeks, the highway agency was insisting that Capital Metro had better speed up and get with the BRT program to contribute its share to the big I-35 rebuild project. Pritchard captured the situation in a subsequent July 13th Austin Monitor report headlined: «TxDOT pressures Capital Metro to act fast on I-35 transit».

As Pritchard’s report elaborated, the BRT plan emerging from the shadows already had quite a bit of detail. TxDOT wanted money to cover the cost of right-of-way “for three bus rapid transit stations to be built in the middle of the highway.”

Those three stations would be near Tech Ridge Center, at Rundberg Lane and at Slaughter Lane. The bus line that would service those stations would operate in new express lanes that TxDOT is planning to add to the freeway. The stations would allow the buses to pull out of the travel lane to allow boarding and deboarding without interrupting traffic flow. The buses would also enter and exit the highway in downtown Austin, perhaps via dedicated transit ramps, and terminate in the south at a park-and-ride off State Highway 45 Southeast.

Capital Metro VP Hemingson had also revealed that the original plan for “BRT” had been even more extensive, but had to be scaled back because of funding limitations.

Hemingson told the board that his team originally proposed to TxDOT a “super bus rapid transit” model that would have included inline stations at 51st Street, Oltorf Street and William Cannon Drive, three roads whose intersections have seen recent infrastructure investments by the state agency.

“It was kind of met with a thud, that idea,” he reported, citing its estimated cost of $400 million, or 10 percent of the roughly $4 billion that TxDOT is planning to spend on the entire I-35 project.

TxDOT’s mounting pressure on Capital Metro was corroborated on July 24th by the Austin American-Statesman. In a news report with the headline «TxDOT: Cap Metro must pay to put buses on future I-35 toll lanes», the paper’s transportation reporter Ben Wear cited the $123 million cost for the “rapid bus stations” and noted that “The agency is pressing Capital Metro for $18 million now to buy land needed for those stations.” However, reported Wear, a “Cap Metro official says the full $123 million cost is beyond its means to pay in the coming years.”

But the benefits of that $123 million investment seemed to be steadily diminishing. An August 11th Austin Monitor news update by Caleb Pritchard aptly titled «TxDOT document reveals limp projections for I-35 bus plan» reported that TxDOT had “projected less than stellar ridership numbers” for the proposed “BRT” service – at most, 3,400 boardings a day. In ridership, that would place the “rapid transit” bus line ninth among the transit agency’s other routes, well behind an assortment of more ordinary and somewhat less spectacular street-based services without heavy investment.

This tends to reflect the major disadvantages of trying to install a viable, higher-quality transit operation within a freeway. Passenger access to and from the stations – especially pedestrian access – is a distinct problem. Transit-oriented development (TOD) – particularly residential development – ranges from poor to actively discouraged. Economic development goals are unfulfilled. Yet, because of the difficulties of construction and the high land values around a freeway or tollway, capital costs are inordinately extremely high.

Yet abruptly, after months of a supposedly impartial, rigorous process of laboriously pursuing data-led solutions … Project Connect and its parent agency Capital Metro were suddenly abandoning that rigorously defined exercise, bypassing the whole process, and embracing a plan for an approximately 20-mile, $123.5-million, 3-station “BRT” line in I-35 that had actually been in Capital Metro’s planning process, albeit at a very low profile, for the past five years.

Curiously, our website (ARN) had already reported hints of such a pre-planned outcome last November. In an article titled «Capital Metro — Back to 1986?» we observed that “Austin’s Capital Metro seems determined to return to the thrilling days of yesteryear – at least in its longrange transit system planning.” A key basis for our suspicion consisted of reports from longtime Austin-area transportation activist Mike Dahmus, together with “with confirmation from other participants”, making it “clear” that “”some implementation of ‘bus rapid transit’ (BRT) on I-35 is (in the words of one observer) a ‘foregone conclusion’.” ARN had noted that this was a “revival” of a nearly identical but “faulty 1986 plan from the agency’s past.”

And additional evidence that a “BRT solution” has actually long been slated for implementation (despite an ostensible “study” process) has continued to emerge. A commentary by David Orr in ARN’s posting of Aug. 31st revealed that a Connections 2025 brochure disseminated by Capital Metro listed the I-35 “Super BRT” plan as if it were already approved as a project in line for implementation.

Minneapolis “Orange Line BRT” — a faulty model

Much of Capital Metro’s case for the I-35 “Super BRT’ plan appears to use a somewhat similar HOV-lane nominally “BRT” operation in Minneapolis as a model. Dubbed the Orange Line, the 17-mile express-bus-on-highway project is currently under development for the metro area’s I-35W corridor. However, the Minneapolis Metro Orange Line project is significantly different from what TxDOT and Austin’s Capital Metro and Project Connect are proposing. (Information regarding the Orange Line project has been obtained via discussion with former Metro planner Aaron Isaacs as well as online material from the Minneapolis Star-Tribune and Metropolitan Council.)

First, it would seem that the status of I-35 in Austin (with almost imperceptible bus service) is nothing remotely like Minneapolis’s 45-year-old, mature, heavily used I-35W transit corridor, with 25 bus routes, 14,000 daily rider-trips, and substantial existing transit investment, proposed for upgrading into the Orange Line (including one in-line station)
.
Minneapolis’s I-35W bus transit system dates from the early 1970s, when the administration of President Richard Nixon was encouraging investment in enhanced bus operations as an alternative to planning what it perceived as more expensive rail transit. In Minneapolis, this started with metered freeway ramps (controlling access to the freeway); beginning in 1972, HOV bypasses to the metered ramps were implemented, with more being added over the subsequent years. Metro also implemented bus-only shoulders on portions of I-35W and feeder highways 62 and 77.

Eventually this operation included HOV lanes (opened in 2009) used by buses. One “in-line” bus station is already in operation in the middle of I-35W.

This program never produced ridership and benefit results anything close to what would be expected of a major rapid transit (or light rail) investment – a drawback that became a major factor persuading Minneapolis decisionmakers to proceed with the Hiawatha Avenue light rail transit (LRT) project (now the Blue Line) which opened in 2004. This raises the question whether it is prudent for Austin to follow a similar course of heavy bus transit investment in the I-35 corridor as its major transit option.

Secondly, the Orange Line is not intended to be Minneapolis’s heaviest major transit corridor. That role is already performed by the region’s two LRT routes – the Blue Line with 31,000 daily ridership and the Green Line with 37,000.

Third, in addition to the already-established heavy infrastructure involved in the Orange Line project, it’s relevant to note all the additional infrastructure in terms of surface dedicated lanes that exists and is being expanded with this project. Downtown Minneapolis already has an entire bus mall. This infrastructure is essential to support the heavy volumes of buses the transit agency channels through downtown Minneapolis. (Fortunately, LRT absorbs a huge portion of the total transit volume and handles this more efficiently with trains.) Are the City of Austin and Capital Metro prepared to include this level of downtown infrastructure investment in the project package in addition to the proposed “super BRT” on I-35?

Finally, it’s important to realize that a “BRT” project nearly identical to what Project Connect is now proposing was proposed and rejected in the late 1980s, in favor of LRT on a somewhat parallel route (including Guadalupe-Lamar). The main reason: the high capital cost of inserting this heavy infrastructure into the narrow I-35 freeway corridor. The proposed high volume of buses (with traffic implications for the Core Area) was also a factor in the elimination of this alternative.

Fake “BRT”, “Super” or otherwise

As one takes a broader view of this entire issue, it is legitimate to question whether it is valid to consider buses running in HOV or HOT (high-occupancy toll) lanes as “bus rapid transit” (BRT) at all.

One of the key criteria specified for “true” BRT has been having a right-of-way or alignment clearly designated as exclusive for the bus-only operation. The basic argument behind this has been that to emulate rail systems, all of which have a defined trackway that passengers know identifies the rail line (especially surface LRT), the BRT operation must have a correspondingly uniquely identified alignment reserved for its exclusive use. This is important in order to (supposedly) impart a comparable sense to passengers and the general public of the presence of the route and where it goes – i.e., a crucial factor in orienting passengers and the general public to this service. An HOV tollway open to general mixed-use traffic does not provide this characteristic.

Furthermore, the TxDOT/CMTA proposal for I-35 “BRT” would have the “rapid transit” buses leave the freeway entirely to serve most stations off the “highspeed” facility. That certainly would seem to violate the concept of a readily understandable, visually clear “rapid transit” route. Not to mention putting a big dent in travel time.

And some final considerations: With three proposed “inline” stations over about 20 miles, the I-35 “BRT” would have an average station spacing of about 10 miles. What “rapid transit” line in the world has station spacing averaging 10 miles? BART (which has some of the function of a commuter rail as well as rapid transit) has an averaging spacing of about 2.8 miles, and that’s unusually long. The next in line, the Washington Metro, averages 1.4 miles.

Our own conclusion: What’s being promoted as “BRT” – bus-style “rapid transit” – on Austin’s I-35 would be basically just a commuter bus operation, with some added amenities.

LRT makes more sense

There’s a far more attractive, effective, workable, beneficial, and ultimately affordable public transport alternative to the TxDOT-Capital Metro-Project Connect express-bus plan packaged as “Super BRT”. This alternative is LRT – specifically, as ARN proposed in our July 31st article «Urban Rail on Guadalupe-Lamar, Not I-35 “BRT”» – a 21-mile LRT line paralleling I-35 but serving the center of Austin.

Running from Tech Ridge in the north to Southpark Meadows in the south, mainly via North Lamar, Guadalupe, and South Congress, such a line would offer dozens of stations and immensely greater accessibility, available mobility, attractiveness, ridership, and benefits to the community.

As our July 31st article indicated, the first segment should be a “starter line” in the Guadalupe-Lamar corridor:

Guadalupe-Lamar (G-L) is the center city’s 3rd-heaviest north-south corridor. In addition to major activity centers, the corridor serves a variety of dense, established neighborhoods, including the West Campus with the 3rd-highest population density in Texas. With Austin’s highest total employment density on Guadalupe-Lamar, an urban rail line could serve 31% of all Austin jobs.

An initial 6 or 7 mile LRT starter line from U.S. 183 or Crestview to downtown could serve as the initial spine of an eventual metrowide system, with branches north and south, northwest, northeast, east, southeast, west, and southwest.

This kind of investment in LRT would appear to represent a far greater value for money, with potential for a much higher ROI (return on investment), than even a lower-cost express-bus project such as that proposed by TxDOT and Capital Metro, and it surely deserves a fair and impartial evaluation through the legitimate Project Connect study process. The attempt to ram through a “rush to judgement” for TxDOT’s “Super BRT” plan (evidently aimed in part to obtain Capital Metro’s buy-in for the I-35 mega-project) deserves to be jettisoned.
