In this study we draw on data from the last two California Household Travel Surveys to examine walking behavior in four major California regions—the San Francisco Bay Area, Los Angeles, Sacramento, and San Diego.
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?
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."
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.
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?
In the last 10 years, transit use in Southern California has fallen significantly. This report examines patterns of transit service and patronage over time and across the region, and considers an array of explanations for falling transit use.
This report examines the socioeconomic changes in South Los Angeles since the Sixties to shed light on what, if any, progress has been made toward addressing issues of access, equity, and justice.
This report provides a conceptual framework for thinking about how more people can live and work near transit, near the major regional investments that county residents are paying for, in ways that maximize social benefits and minimize social costs.
This study explores the travel patterns, needs, and mobility problems faced by diverse low-income, inner-city older adults in Los Angeles in order to identify solutions to their mobility challenges.
The goal of this evaluation report is to determine whether parklets, a relatively new streetscape improvement type, is an idea that works along Santa Monica’s Main Street corridor.
