In the face of growing levels of congestion and persistent air quality problems, planners increasingly see community design as a way of reducing automobile dependence. Because of growing levels of obesity and the attendant health problems, public health officials have also turned to community...

California is in the midst of a demographic transformation. According to the 2000 U.S. Census, nearly 30 percent of the California population is now foreign-born, more than 50 percent of the population belongs to a minority group, and the elderly (those 65 and older) comprise 11 percent of the...

Future air pollution emissions in the year 2030 were estimated for the San Joaquin Valley (SJV) in central California using a combined system of land use, mobile, off-road, stationary, area, and biogenic emissions models. Four scenarios were developed that use different assumptions about the...

Expectations remain high that information communications technology (ICT) might reduce travel. The rapid evolution of technology, combined with a dearth of longitudinal data, has made it extremely difficult to assess the affects of ICT on travel. Results are compared from two independent but...

The purpose of this paper is to examine the relationships between travel behavior and immigrant status. The National Household Travel Survey (NHTS) allows us to explore the relationships between travel behavior and characteristics that are usually hard to discern in surveys with smaller samples....

A number of studies have examined the adoption of information and communication technology (ICT) and its impacts on personal travel, both at a general level and in the context of a particular kind of activity. While it is not surprising that initial attention has focused on the effects of ICT on...

This report summarizes findings from the 2008-09 UC Davis Campus Travel Survey, administered annually each fall to a stratified random sample of the UC Davis community. It includes estimates of the overall campus mode split, average vehicle occupancy, numbers of vehicles arriving on campus,...

Since its initiation in the early 20th century, the federal surface transportation program has focused on highway construction and continues to do so to this day. However, over the past three decades, views of non-motorized modes and of federal interest in promoting them have changed...

In recent years, transportation planning has devoted new attention to the goal of increasing the nonmotorized trips of children and adults, both as a means of increasing physical activity and as a means of reducing motorized trips. For children, much discussion has focused on the journey to...

In recent years, transportation planners have devoted more attention to the goal of increasing the non-motorized trips of children and adults. Non-motorized trips are considered important as a mean of reducing motorized trips as well increasing physical activity. Indeed, lack of physical...
