Abstract

Effectiveness of bus signal priority (BSP) study evaluates bBSP's impact on traffic operations. The goal was to examine how different situations such as the level of congestion, placement of bus stops, presence of express bus service, and number of transit vehicles on route, require different techniques of BSP such as real time or fixed time based control. those techniques also utilize a variety of different control strategies such as phase suppression, synchronization, compensation, and green recall. Five agencies utilizing BSP around the country were studied to determine which types of priority are used in certain conditions and what technology is being implemented.
