【摘要】：由于城市交通网络中交通流固有的时间和空间关联性,交叉口间的信号控制方案也具有一定的关联性。通过VISSIM仿真的方法,研究了周期、绿信比和饱和度对邻近交叉口控制方案的影响,这种影响可分为两个方面,对邻近交叉口控制效果的影响和邻近交叉口配时参数进行的调整。结果表明周期不会改变邻近交叉口的流量,但是绿信比和饱和度均会改变。3种因素都会显著地改变邻近交叉口的控制效果。而且流量的变化规律性较强,但控制效果的变化更复杂,难以事先预知。
[Abstract]:Because of the inherent temporal and spatial correlation of traffic flow in urban traffic network, the signal control scheme among intersections is also related to a certain extent. Through VISSIM simulation, the effects of period, green signal ratio and saturation on the control scheme of adjacent intersection are studied. This influence can be divided into two aspects: the effect of the control effect of adjacent intersection and the adjustment of timing parameters of adjacent intersection. The results show that the cycle does not change the flow of the adjacent intersection, but both the green signal ratio and saturation change the control effect of the adjacent intersection significantly. The change of flow rate is more regular, but the change of control effect is more complicated and difficult to predict.
