The stressful characteristics of commuting constraints are conceptualized in terms of both physical and perceptual conditions of travel impedance. This study develops and operationalizes the concept of subjective impedance, as a complement to our previously developed concept of impedance as a...

A stressful nature of expose to traffic congestion in automobile commuting has been demonstrated in previous quasi-experimental research that has been measurement-intensive but conducted with relatively small samples. The present study examined commuting stress in automobile travel with a large...

With this first issue of Access, we at the University of California Transportation Center seek to introduce our research to a diverse community of readers. By presenting our findings in a nontechnical format, we hope to make them accessible to professionals in various fields and to citizens who...

The physical and perceptual dimensions of commuting travel impedance were again found to have stressful consequences in a study of 99 employees of two companies. This quasi-experimental replication study, which focuses here on home environment consequences, investigated the effects of physical...

Aggression and the automobile have had a long standing association, yet research on aggressive behavior has neglected the roadway context. This chapter reviews existing work which has included archival analysis, field interview studies, personality research, and field experiments. Among the...

Automobile driving and aggressive behavior have had an extensive association. Themes of dominance and territoriality have long been part of automobile driving, which has also involved flagrant assaultive actions. Recent episodes of roadway violence in metropolitan areas have raised community...

Everyone knows that being stuck in traffic is stressful, and few look forward to long commutes on congested roadways. But the negative effects of traffic congestion go beyond frustration and fatigue. Our research at UC Irvine since the late 1970s has discovered adverse health impacts of what we...
