小型信控环形交叉口自适应控制模型与算法研究

针对各进口流量不均衡的城市小型环交,本文以单位绿灯时间通过的车辆数最大为目标,结合排队长度与等待时间的限制,建立了小型环交单进口放行自适应控制模型。在不同的流量均衡度下,仿真结果表明本文建立的自适应控制模型相较于单进口放行定时控制与左转二次停车控制,在交叉口平均延误、排队长度等方面均有较为明显的优势。

Research on Adaptive Control of small Roundabout

For the small city roundabouts with imbalance flow, this paper aim to maximum the green time utilization of it, combined to limit queue length and waiting time, we proposed a single-import clearance adaptive control model of small roundabout. Simulation results show that under different flow equilibrium degree, the adaptive control model established in this paper has obvious advantages over the fixed- timing control and turn left at the second stop line control on average delay and queue length.
