摘要: 分析了行人过街对路段上机动车流运行规律的影响, 确定了交叉口各进口道机动车平均延误计算公式。结合干道协调控制系统, 建立了交叉口与人行横道信号协调控制优化模型。以最小交叉口总延误与最大通行能力为目标函数, 以行人过街最小绿灯时长为约束条件, 选择周期时长、绿信比与相位差作为决策向量, 在保证各参数共同优化的情况下, 用遗传算法进行模型求解。计算结果表明: 交叉口总延误实测数据降低了35.4%, 通行能力提高了0.1%;与经典Webster算法比较, 交叉口总延误降低了81.3%。可见, 该模型可行有效, 且较好地提高交叉口运行效率。Abstract: The effect of pedestrian crossing on road traffic flow was analysed, and the formulae of average delaies of vehicles at the imports of intersection were determined. A signal coordination control optimization model between intersection and cross walk was built based on arterial road coordinate control systems. The mininum total delay and maximum capacity of intersection were taken as objective functions, the shortest crossing times were taken as constrain conditions, and the green times of phases and offsets were taken as control parameters. As the parameters were co-optimized, genetic algorithm was resorted to solve the model. Computation result shows that compared with actual datat, total delay reduces by 35.4%, and traffic capacity increases by 0.1%. Total delay reduces by 81.3% compared with traditional Webster method. So the model is feasible and can improve the traffic efficiency of intersection.
