| 摘 要： | 通过对交叉路口交通流到达和排队延误规律的研究,提出了一种新的交通信号控制理论,并建立了以PI值最小为目标的交通信号配时优化理论模型。该信号配时方法与通常采用的单点自适应信号控制方法的区别在于不但考虑了交通延误,而且考虑了停车次数,实现了对交通延误和停车次数两指标的优化,从而保证了以车队形式到达的交通流可以不间断地通过交叉路口。由于以实时交通流的到达规律为依据进行信号优化配时,因此,该信号配时优化模型又是实时自适应交通信号控制优化模型。

| Abstract: | Through studing the rule of the traffic flow in the traffic crossing and a new optimization approach for signal timing in the intersection is proposed.This approach considers not only the traffic waiting delay but also the stops and starts-up.Combining traffic delay,stops and start-ups,a concept PI(Performance Index) and a model based on PI value are presented.Using this model the signal timing can be optimized to reduce not only traffic waiting delay but also stops and start-ups. |

| Keywords: | traffic signal PI value traffic waiting delay traffic stops and start-ups delay |
