干线协调控制中公共周期优化方法研究

现有线控公共周期确定取决于关键交叉口交通状态，其目的是满足交通状态最差的交叉口不会产生过饱和现象，但未考虑对实际线控效果影响且可能增大其他交叉口延误。文章分析了周期调整对延误和通行能力产生的影响，确定了干线协调下公共周期的调整区间。在此区间内以交叉口实际间距与理想间距偏差为优化目标，采用优选出的鲁棒简面体爬山法优化目标函数实现绿波带最宽。实证表明所提出的优化方法得到的绿波带和平均延误好于数解法，且对通行能力影响很小。

Public Cycle Optimal Method at Arterial Signal Progression

Currently the common cycle of linear signal progression is determined by the critical intersection involved in coordination control,which ensures that the worst intersection will not be oversaturated.However,it does not consider its impact on the progression performance and the delay in other intersections could increase.Therefore,this paper studies the impact of cycle length on the delay and capacity at arterial intersections,and implements simplex method to reduce the gap between actual and ideal space an...
