摘　　要：随着车辆拥堵现象日益严重,如何提高交叉口的通行效率已经得到学术界的广泛关注。为充分地利用交叉口有限的物理空间资源,提出了一种相邻无信号交叉口车辆协同调度方法。首先,将交叉口划分为互不相交的物理空间资源,进而把交叉口车辆通行控制问题转化成资源调度问题。然后,基于Petri网构建了一个交叉口资源调度模型。为了避免车辆相撞,模型要求同一物理空间资源在同一时刻只能被一辆车占用。实验结果表明:到达率较低时,与采用传统信号灯的控制方式相比,无信号控制方式能有效提高通行效率;到达率较高时,交叉口发生拥堵。但与无协同的控制模式相比,相邻交叉口协同控制模式可以更好地缓解拥堵现象。As vehicle congestion becomes increasingly severe,how to improve the capacity of intersections has been widely investigated in the literature.To make full use of the limited physical space resources,a cooperative control method for vehicle scheduling at two adjacent intersections is presentded.Firstly,an intersection is partitioned into several disjoint spatial traffic resources so that the traffic control problem can be transformed into the resource scheduling problem.Then,we construct a signal-free intersection resource scheduling model using Petri nets.For safety,the model requires that each partitioned spatial traffic resource can be occupied by only one vehicle at a time.Experimental results show that:when the arrival rate is low,compared with the traditional signal control method,the signal-free control method can improve the traffic efficiency of intersections.When the arrival rate is high,intersections are jammed.However,compared with non-cooperative control mode,the collaborative control mode can better alleviate the congestion.
