Report Identifies Best Toll Truckways Pilot Projects

In June 2002, two Reason colleagues and I accomplished the seemingly impossible. We persuaded both the American Trucking Associations and the National Safety Council - traditionally on opposite sides of the fence over big-rigs known as Longer Combination Vehicles - to endorse a concept we called Toll Truckways. Our June 2002 report ( proposed that these highly productive trucks (long doubles and triples) be allowed to operate into states where they are currently banned by federal law, provided that they operate on new, barrier-separated truck-only lanes designed for heavy-duty service. Our study reported the results of extensive simulating modeling (at CCNY) which indicated that many such truckways would add so much value for trucking companies that they could be self-supporting from tolls. House Transportation & Infrastructure Committee Chairman Don Young (R, AK) liked the idea so much that he arranged a room for our news conference in the Rayburn building, and personally expressed his interest in the idea.

Fast forward 20 months. The pending House reauthorization bill, TEA-LU, contains a provision for truck-only lanes, but thus far no specifics. To help Chairman Young and the Committee fill in the details, Reason is today releasing a new study which identifies the most promising long-distance Interstate corridors where toll truckways would make sense, and offers specific suggestions for what's needed in TEA-LU to create a pilot program to test the concept during the coming six years. You can find the full report at We have also posted an 8-page summary version at

What co-author Peter Samuel and I set out to do was to comb through mountains of data to identify which specific trucking corridors seem most likely to succeed as toll truckways, as defined in our 2002 study. The key value-driver of that concept is to give the users (trucking companies) something much more valuable than they can get today, namely the ability to haul up to twice as much payload per driver. That's what long doubles and triples can do, if allowed to operate into states now covered by the 1991 federal freeze on LCVs, which limited their use to the handful of western states and eastern turnpikes which had allowed them up till then. So we pored over maps showing the existing LCV routes, and mined data in a massive goods-movement database provided to us by Wilbur Smith Associates.

We also went directly to potential key customers of toll truckways: long-haul trucking companies that already operate LCVs in states where they are legal. We surveyed them to ask which routes they would most like to have added to the fledgling LCV network. We added our own missing links to their suggestions, and ended up with 39 possible corridors with high current and projected truck traffic and some potential as new LCV routes. We crunched the numbers, reducing that set to 20 semi-finalists and then the 10 best routes. "Best," in our analysis, means most likely to be financially feasible as toll corridors and therefore characterized by relatively higher revenues and lower costs to construct than other corridors. And the winners are:

Our study also contains specific recommendations for legislative provisions needed to enable pilot toll truckways to exist, most importantly the legalization of LCV operations on such truckways in states currently subject to the LCV freeze, the ability to charge tolls on the truckways, and a mechanism for interstate compacts to facilitate the majority of such truckways which need to involve more than one state. Chairman Young has just re-affirmed his interest in the concept, so we look forward to the House mark-up of TEA-LU.

How Tolls Can Get Us to a Highway Reauthorization Consensus

The standoff over how big the federal surface transportation program should be continues. The Senate has passed S.1072, calling for a $318 billion program ($255B for highways, $57B for transit) over six years, but with no fuel-tax increase. The House's TEA-LU is still officially at $375B (funded partly by a sizeable fuel-tax increase), but over the past week or two that number seems no longer cast in concrete, particularly in light of the Administration's veto threat over the Senate bill, which the Administration considers an unacceptable drain on general federal revenues. Though S.1072 passed by more than the two-thirds required to override a veto, it's not clear that GOP leadership in the two houses would actually vote to overturn the President's first during a presidential election year. Which means the stalemate continues.

In an article in the forthcoming (April) issue of Public Works Management & Policy, I suggest that aggressive expansion of permission for states to use tolls could bridge much of the gap between the White House and congressional transportation advocates.(Go to for information on how to get a sample issue; I'm not sure when the April issue will be posted.) The long and short of it is my estimate that a combination of toll-friendly policies could expand highway investment by something like the $50 billion gap separating the Administration and Senate bills. And since a program the size of the Senate one now seems like the largest that will emerge, this approach really should be pursued.

The Administration's original SAFETEA bill included several key toll-friendly provisions:

In addition, two other key provisions under discussion are Rep. Mark Kennedy's FAST lanes proposal and Chairman Young's truck-only lanes title (the latter discussed in the previous article). The FAST Act would permit all states to add electronically tolled lanes to congested Interstates, but require them to eventually remove the tolls. As I point out in the PWM&P article, that provision would likely cause states with large existing toll systems to decline to participate. And that might cut in half my estimate of $28-50 billion of net new investment if all states took full advantage of FAST lanes (see for details of my estimate).

Thus, some very careful blending of these various provisions is needed, to give states a menu of options for making use of tolls and public-private partnerships to expand highway investment. The Senate adopted a last-minute compromise blending of FAST and Variable Toll Pricing, which has some important flaws. But further efforts along these lines could give states the means to tap into the billions in private capital that is able and willing to invest in sound toll projects.

UCLA Dings STPP Report on Transportation Costs and Sprawl

Last issue I summarized two critiques of a paper from the Surface Transportation Policy Project from last July purporting to show that transportation costs pose a large and growing burden to low-income people, especially in low-density metro areas where transit cannot handle most trips. Now comes another critique, this one from Evelyn Blumenberg at UCLA's urban planning department. She reviewed expenditure data from the Bureau of Labor Statistics and found that the lowest-income quintile spends the least on transportation (17% of income, compared with 18 to 21% for other quintiles). In addition, she tracks this percentage over time, finding that it has generally declined since 1984 for the low-income quintile.

As Blumenberg points out, "Households make trade-offs between housing and transportation costs that include time costs." And "one cannot draw conclusions regarding the burdens of transportation costs without also considering the benefits of transportation expenditures." She concludes, "Claims that excessive transportation costs, and more specifically automobile ownership, are directly responsible for reducing home ownership among low-income households are not supported by the data."

Correction re London's Congestion Pricing

In Issue #13, there was a glitch in my report on London's congestion pricing, which a sharp-eyed reader pointed out. Somehow I wrote that "travel times have markedly increased" within the pricing zone, when what I meant to say was that travel times have markedly improved. That's quite a different outcome, needless to say! In fact, the new first-year report on London's congestion pricing program finds that vehicle speeds have increased by 14% and congestion is down by 30%.

Transportation Finance Summit Next Week

Over 250 people have signed up for the International Bridge, Tunnel and Turnpike Association's Transportation Finance Summit at the Grant Hyatt Washington next Thursday and Friday, March 4 and 5. But I'm told there are still places available if you aren't yet among them. An impressive array of speakers, both domestic and from overseas, will discuss an array of highway financing tools. I'm one of the speakers, but I'd be there in any case, given the great line-up of talent and expertise that IBTTA has assembled. Reason Foundation is one of the co-sponsors, along with the American Public Works Association, American Road & Transportation Builders Association, the Eno Transportation Foundation, and others.
