Research Highlights

Understanding the Transit-Dependent Population

Jennifer Dill
Lisa Bates
Public transit in metropolitan areas serves multiple and sometimes competing objectives. Increased attention on "choice" riders and transit as an economic development tool has shifted resources towards suburb-serving rail systems at the expense of inner-city bus service. This investment strategy may be at odds with the social service role that transit plays in providing mobility to those without other transportation options. However, there is a lack of research on the "transit-dependent"popul... Read More

Evaluation of Bike Boxes at Signalized Intersections: Phase 2

Christopher Monsere
Analyses of motor vehicle and police-reported crash data reveal that nearly 68 percent of bicycle crashes in Portland, Oregon occur at intersections (PDOT, 2004) which is consistent with national trends (Hunter et al., 1996). Hunter et al. (1996) also found that 12.2% of crashes involving bicyclists and motor vehicles occurred when a motorist turned or merged into a cyclist's path. Of these intersection crash types, a common crash pattern is the "right hook," where right-turning motorists ... Read More
