Optimization of Short Connection Intersection Control Scheme
摘要
Abstract
This paper describes vehicle on road arrive-departure balance control based on the short connection intersection topology, applies Store-and-Forward theory and queuing theory, and focuses on the intersection control parameter optimization. The parameter optimization includes phase difference optimization and green ratio optimization. On the premise of ensuring each individual a fair opportunity to use the road, avoiding branch line upstream queuing and evacuating from rapid roads rapidly, considering the two indicators of urgency and size of queue, a special non-linear programming model is established, which can limit threshold value of phase green time safely, efficiently and fairly. Furthermore, the model is solved through the Frank-Wolfe algorithm. Simulation result shows that the optimization model can effectively prevent the upstream queuing on short connection import line and improve the traffic capacity at the intersection.关键词
