Coordinated control models for stop and delay under over-saturated traffic conditions
过饱和交通状态下的停车延误协调控制模型

In the duration of over-saturated traffic conditions, this paper studies the approach-delay under coordinated control with cumulative arrival-departure diagram based on the time that platoon reaches downstream intersection: 1) platoon arrives in a cycle with the start of red phase; 2) platoon arrives throughout a cycle with the start of red phase. This paper proposes stop and delay coordinated control models under over-saturated traffic conditions for different arrival types, and obtains conclusions about the relationship between performance indexes(number of detained vehicles, number of stops, and delay) and coordinated control variables(relative offset, common signal cycle). The control models have been analyzed and verified by traffic simulations. This method provides a theoretical basis for the coordinated control technology under over-saturated traffic conditions.
