Socioeconomic, Health, and Human Factors

TRB’s Transportation Research Record (TRR) No. 2452 consists of 14 articles that examine the impact of highway investment on the economy and employment across U.S. industrial sectors; the evolving connection of transit, agglomeration, and growth of high-technology business clusters; an analysis of socioeconomically disaggregated longitudinal employer–household dynamics data to understand commuting, job clusters, and travel burdens; the effect of accessibility on property prices; and the impact of bus rapid transit and metro rail on property values in Guangzhou, China.

This TRR issue explores accessibility for low-income workers in New Orleans, Louisiana, after Hurricane Katrina; travel behavior of the poor after welfare reform; impact of attitudes and life stage on decline in rates of driver’s license acquisition by young people in Melbourne, Australia; the use of a health impact assessment for transportation planning; and health impacts of transportation projects in an urban Indian context.

Additionally, this issue of TRR summarizes rural communities and transportation equity in California’s San Joaquin Valley; workplace neighborhoods, walking, physical activity, weight status, and perceived health; dispersion modeling of traffic-related air pollutant exposures and health effects among children with asthma in Detroit, Michigan; mediators in the relationship between commute time and subjective well-being.
