Managing Pedestrian and Car Interactions
PI: Carlos F. Daganzo, UC Berkeley
Abstract: This research will examine the pros and cons of increasing the number of crosswalks across streets without traffic signals. It will consider cases where pedestrians have priority, as in California, and also where cars have priority. We expect to show that in both cases increasing the number of crosswalks usually benefits pedestrians and enhances the flow of cars. The effects on pedestrian hours and distance traveled (PHT and PKT) and on traffic (VHT and VKT) will be quantified. Policy recommendations for different urban and suburban environments will also be provided. The research will then be extended to signalized streets with a focus on the operation of pedestrian signals for crosswalks serving transit passenger transfers. A strategy where pedestrians can request preemptive priority over traffic when a bus is offloading passengers will be considered, with due consideration of its effect on cars. This type of operation is expected to benefit transfers and incentivize the use of public transportation.
