摘要
选取车辆在桥面上的排队长度和CO排放量为综合评价指标,构建考虑排放的桥梁两端信号协调控制多目标配时模型;运用改进的遗传算法设计模型的求解步骤,并以福清市玉融大桥实例进行验证。结果表明:与现状相比,在晚高峰阶段,交通总排放量降低6.1%,桥上排队长度降低11.1%。
The evaluation of the bridge queue length and CO emissions are selected to construct multi-objective model of the signal coordination control at both ends of the bridge considering emission; and the solution steps of the improved genetic algorithm design model is used , and has been validated by the examples of Yulong bridge in Fuqing City. The results s how that compared with the status quo, in the evening peak period, the total traffic emissions decrease 6.1%, the bridge queue length decreases 11.1%.
