Instead it has a couple dozen, says Texas Transportation Institute research engineer Tim Lomax.
The Texas Transportation Institute recently claimed they do, although their methodology has been flawed before.
For travel delays, we used the Texas Transportation Institute's 2005 Urban Mobility Report, which compiled the annual delay per traveler for urban areas.
Last week, the Texas Transportation Institute released its annual Urban Mobility Report, a collection of terrifying traffic stats that arrive on a beeline to transit beat reporters.
Moreover, a study by the Texas Transportation Institute found that highways with diamond lanes lacking a physical barrier separating them from regular lanes have a 50 percent higher incidence of injury accidents.

The senators cited a Virginia Tech Transportation Institute study that found that truck drivers who texted while driving were 23 times more likely to crash or get into a near-accident than undistracted drivers.
It attributed the increased risk to the almost five seconds it found that the driver's eyes were off the roadway while texting, said Rich Hanowski, the director of the Center for Truck and Bus Safety at the transportation institute.
Last year, CEOs for Cities released a detailed response to the Texas Transportation Institute (TTI) report, faulting the study for failing to include travel times, an omission that tilts the results in favor of metro regions splayed out.
Sending or receiving a text takes a driver's eyes from the road for an average of 4.6 seconds, the equivalent of driving the length of an entire football field, blind, at 55 mph, according to researchers at the Virginia Tech Transportation Institute.
Auto makers point to studies, including one by researchers at Virginia Tech Transportation Institute, which show that talking on a cellphone increases the risk of a crash or near-crash by 1.3 times over regular driving, while physically dialing a number increased the risk 2.8 times.
Obtaining a driver's license was once a ritual of American youth, and yet by 2010, more than 30% of Americans ages 17 to 19 did not possess a driver's license, up sharply from 12.7% in 1983, according to a study by the University of Michigan Transportation Research Institute.
The California Center for Innovative Transportation is an affiliate of the UC Berkeley Institute of Transportation Studies.

So we can wait for the shock to come and then allow our economy to falter while we retool for electric powered transportation, or we could institute a proactive energy policy that begins to wean us off our petrol habit, and also protect our nationwide network of comfort castles.
