摘要：	This paper describes an adaptive dynamic procedure to design and evaluate signal coordination and queue management strategies along oversaturated arterials. The procedure can initiate queue management plans with different degrees of priority to mainline and cross-street traffic. It is based on a dynamic procedure that designs signal control parameters(offsets and green times) with explicit consideration of current and projected queue lengths. The main idea is to dynamically manage the formation and dissipation of queues on system links using a responsive signal control algorithm that can be customized to assign different priorities to arterial and cross street traffic to achieve a desired queue management strategy. The problem was formulated as a throughput maximization subject to state, control and queue management strategy choices. Solutions were obtained using Genetic Algorithms (GAs). Several queue management strategies with varying degrees of priority to arterial and cross street traffic were tested. The results showed that the proposed procedure was able to initiate signal timing plans to respond to different traffic needs and priorities, and was able to discriminate between the merits and drawbacks of the different management plans. The procedure is adaptive and dynamic, therefore has very good potential for real-time implementation in ITS setting.
