Public transportation is a very economical, efficient, and environmentally friendly means to move a large number of travelers in an urban environment. Urban congestion due to low passenger throughput, high-rise gas prices, and heavy tailpipe emissions caused by private passenger vehicles are major problems that could be mitigated by transit vehicles. Since 2006, the United States Department of Transportation (USDOT) Urban Partnership Agreement program has been aggressively pursuing public transit as one of the four strategies to reducing traffic congestion (Jackson et al. 2008). In order to improve transit operations, roadway operators often seek to implement preferential treatments for transit vehicles. Some treatments provide preference to buses via modified roadway segments, such as median bus-way, exclusive lanes, and the like. Others furnish priority through locations that yield the best benefits, such as transit signal priority (TSP), queue jump and bypass lanes, curb extensions, and so on. Two of the five factors that directly influence customers perceptions of the transit service quality are travel time and reliability (Kittleson & Associate et al. 2003). Providing TSP to the transit vehicles in need is a viable strategy to reduce bus delay and improve bus reliability (Danaher 2010). To achieve these goals, a modern TSP system requires at least the knowledge of bus arrival times, but it can also make use of additional information such as passenger load and schedule adherence.
