| 摘 要： | 在分析车流到达与离去性质的基础上,确定渠化十字交叉口相位的方案集,提出以相位非均衡损失和二次停车延误作为其不同饱和度下信号控制优化的主要目标,辅之以总延误和车均延误时间,兼顾行人过街影响,建立交叉口小时内有限定义域整型优化模型并给出算法。以广州市天河北/天河东交叉路口为例,择一日进行信号控制优化,计算结果表明：优化空间在10%～40%时,模型具有良好的适应性。

| Abstract: | Based on the analysis of characteristics of arrival and departing vehicle flows,the optional phasic schemes for channelized intersection are ascertained,phasic disequilibrium loss and twice stop delay are selected to be the primary criterion to optimize signal control for intersections under different saturated conditions.Considering pedestrian crossing,total delay and average vehicle delay are also chosen to be the optimized goals.A finite domain integer optimized model is established and its algorithm is also given.Taking the intersection of North Tianhe-East Tianhe for example,its signal control optimization of some day is carried on.The results show that this optimization method＇s improvement degree is 10% to 40%,and this model is adaptive well. |
