Active Transit Signal Priority considering Overlapping Phase in Artery progression
Current active transit signal priority (TSP) methods are based on real-time detection of information, often with the green extension and early green to make bus pass through the intersection as soon as possible. In this paper, according to domestic environment, applying active transit signal priority in artery coordination system, using related transit priority principle and parameter, can not only guarantee to execute transit priority, but also make the impact of transit signal priority on coordination system minimum. Moreover, the active transit signal priority in artery coordination system should consider the intersection with irregular phase, such as overlapping phase to ensure traffic flow smoothly proceed. So this paper provides active transit signal priority considering overlapping phase in artery progression (TSPOP), and this new green decision model including green of overlapping phase, green of priority transit phase considers green of overlapping phase in early green strategy can keep the same and in green extension strategy can change as flow needs and transit priority request. Finally based on effect of the green extension and early green on general traffic and bus traffic by simulation analysis, using delay of the intersection, this thesis shows the result: TSPOP can reduce bus delay to transit priority and better than transit signal priority without considering overlapping phase in the degree of transit priority, and also can keep the delay of intersection little increase. Therefore, TSPOP in artery progression is effective, which can provide a theoretical foundation and application experience in practice. 1
