Bidirectional Green Wave Coordinative Control Based on Flexible Phase
The control strategy and the parameter model is the core of advanced traffic signal control system,while the phase design of traffic signal is the most creative part and also the prerequisite of control strategy to realize.In view of the present urban traffic congestion situation on the trunk road,this article proposed a kind of flexible phase sequence coordination control optimization scheme based on the NEMA phase,and gave the corresponding design principles.Then,the paper gave bidirectional green wave bandwidth maximization model based on flexible phase referring to MAXBAND core mathematical model.Finally,the example verification shows that comparing with traditional phase sequence strategy,flexible phase strategy has a certain superiority,and can effectively improve the trunk road traffic efficiency and alleviate urban traffic jam.
