Closed-Loop Signal Control Strategy Considering Instantaneous Stopped Delay[J]. 2012, 46(2): 11-16.
提出一种基于瞬时停车延误的孤立交叉口信号灯闭环控制策略.以交叉口瞬时停车延误总量作为控制参量
其值达到阈值时实时切换交叉口信号灯状态
把信号灯绿灯信号分配给需求最高的道路
不再有信号灯周期的概念.在车流量400~800辆/h变化的情况下
进行了传统的Webster周期控制和新策略控制仿真对比实验.仿真结果表明:新策略控制条件下
车辆平均通行时间明显小于传统控制策略
在800辆/h的流量下
仅为传统策略的44%; 该策略对控制阈值不敏感
当流量为800辆/h时
车辆平均通行时间最大相对误差仅为11%; 该策略获得的多组平均通行时间具有较小的方差
当流量为800辆/h时方差仅为0.895 s.
For instantaneous stopped delay
a closed-loop signal control strategy is proposed. The total instantaneous stopped delay at an intersection is taken as the control parameter to realize real-time switch of the traffic light status when the amount reaches the threshold
and green light signal is adaptively distributed to the most designed lane instead of the regular traffic signal cycle. When the traffic flow in a lane changes from 400/h to 800/h
a comparatively simulation is conducted following the proposed strategy against the Webster control strategy. Under the direction of the proposed strategy
there is an obvious cut-down of the average passing time for all cars in the lane
and for a traffic flow of 800/h
the average passing time is spent for only 44% of that under the traditional strategy. The proposed control strategy is insensitive to the control threshold
and the obtained maximum relative error of the average passing time reaches only 11%. The minor variance among multiple data of average passing time gets to 0.895 s for a traffic flow of 800/h in a lane at the intersection.
