In 1997 the Ann Arbor (Michigan) Transportation Authority began deploying a set of integrated, advanced public transportation system technologies in its vehicles, stations, and control center. Selected findings are summarized of a multidimensional evaluation of the effects of the system on schedule adherence and transfer time, passenger perception, and drivers. Some improvement in on-time performance was observed in vehicle departures from major transfer points, though not in arrivals. Modest improvements were observed in transfer coordination for routes planned for timed transfers....

Busways have been reported to carry up to 28,000 passengers per hour per direction (pphpd). However, recent passenger counts indicate that the exclusive busway in Bogotá, Colombia, has a flow of more than 35,000 pphpd. This passenger flow is achieved despite poor operating conditions and a general lack of maintenance without a city busway management and operation authority. Consequently, there is little police control, no systems management, and scarce information for users. These conditions should affect passenger flow negatively, but the Bogotá busway carries more passengers than...

Proximate commuting is a potential employer-based travel-demand management program under which large, decentralized employers reassign each voluntary participant to a job location (with the same employer) closer to the participant’s residence to reduce commuting distances. Key to determining proximate commuting’s feasibility and potential success are the identification and estimation of its commuting benefits. A model for quantifying the distance and time savings of proximate-commuting programs is presented. It relies on stated preference information regarding an employee’s...

This report examines the link between truck driver pay and driver safety. It establishes a relationship that is important for policy purposes because it suggests that low driver pay, which we expect is linked to low but unmeasured human capital, may be an important predictor of truck driver safety. The study uses three different data sets at three different levels of analysis to demonstrate this link. The study also includes an estimation of the truck driver labor supply curve, an important contribution to understanding drivers’ (and carriers’) preferences for balancing income and work...
