The valuation of travel time savings has been an important theme in transportation research because it is the single largest contributor to the benefits of many transportation projects. It also plays a central role in deciding about the size and scope of public investment and has important...

Equity and environmental justice issues have again become prominent topics of debate in transportation planning and research in the last ten years. Advocates for environmental justice – for short, EJ – have made themselves highly visible in many transportation planning and...

The San Pedro Bay Ports (SPBP) complex of Los Angeles and Long Beach is the largest container port in the U.S., and a very important contributor to both California’s and the nation’s economies. Although the benefits of the SPBP activities are enjoyed by the whole country, the...

Claims that roadway investments spur new travel and thus fail to relieve traffic congestion, known as induced demand, have thwarted road development in both the United States and abroad. Most past studies point to a significant induced demand effect. This research challenges past results by...

In August 2002, AC Transit – the principal bus operator serving the eastern shore of the San Francisco Bay – began distributing free bus passes to low-income middle school and high school students in the transit service district. The program developed in response to grassroots...

The objective of this research is to examine processes of activity scheduling and rescheduling by experiments. Activity scheduling processes were examined by using a combination of mail surveys and telephone interviews. It was found that individuals’ schedules are hardly complete....

After a 5-year study of transportation planning in the San Francisco Bay Area, we have concluded that the contentiousness we observed in the process was due in great part to differences in participants’ styles of planning and not solely to disagreements over desired outcomes. Each style...

Modern panel surveys frequently suffer from high and likely non-ignorable attrition, and transportation surveys suffer from poor travel time estimates. This paper examines new methods for adjusting forecasts and model estimates to account for these problems. The methods we describe are...

Despite its application in many fields, map matching in studies of travel/transport geography is unique in two aspects: 1) The correct road links traversed by the traveler need to be unambiguously identified; 2) All the identified links should form a meaningful travel route. This paper discusses...

Moving the marketplace to clean and efficient vehicles is proving a complex, difficult, and long-term project. The first step, the development and commercialization of several technologies including electric, hybrid-electric, and alternative fuel vehicles is well underway. Now we must take the...
