Not So Fast: Traffic Delays, Access, and Economic Activity in Greater Los Angeles and the San Francisco Bay Area

2025-06-01T14:36:24-07:00

The TTI estimated that traffic congestion cost the Bay Area economy – by some measures the nation’s most vibrant regional economy – a staggering $3.1 billion in 2014. But do such measures really capture how congestion and the conditions that give rise to it affect regional economies?

The California Gas Tax Swap: A Study of Revenue Volatility in Transportation Planning

2025-06-01T14:36:24-07:00

In the mid-2000s, the state began diverting fuel sales tax money previously earmarked for mass transit to pay debt from highway and rail bonds, as well as general services supported by the state. A state court, however, soon ruled that diverting transportation sales taxes to the General Fund was invalid. Therefore, the Governor proposed a “Fuel Tax Swap."

Toward Accurate and Valid Estimates of Greenhouse Gas Reductions from Bikeway Projects

2025-06-01T14:36:25-07:00

Calculating GHG emissions reductions for transportation projects is both difficult and imperative for policy. The existing scholarship reflects three problems: 1) the complexity of transportation systems and travel behavior, 2) the lack of data to support emissions calculations, 3) the inability to apply existing academic models to policy implementation.

Congested Development A Study of Traffic Delays, Access, and Economic Activity in Metropolitan Los Angeles

2025-06-01T14:36:25-07:00

TTI estimated that traffic congestion cost the LA economy a staggering $13.3 billion in 2014, based on premise that moving slowly wastes time and fuel, costs that are multiplied over millions of travelers. But do such measures really capture how congestion and the conditions that give rise to it affect regional economies?
