基于车流波动理论的匝道达到控制与仿真效果评价
Ramp Metering and Simulation Effect Evaluation Based on Traffic Fluctuation Theory
摘要
Abstract
The active traffic control in the merging area,which takes ramp arrival control as the main body,is the main means adopted by the expressway and urban expressway to improve the capacity and traffic safety of the weaving area.In this study,the his-torical real traffic data and the optimized theoretical model of speed fluctuation are used to build the vehicle arrival model in the process of congestion and queue weaving,and the optimal control scheme under the mixed control decision is quantitatively analyzed.Through the optimized simulation platform,the vehicle trajectory,distribution and conflict status are obtained,and the actual effect of the con-clusion is verified.This study takes Qinhong Interchange as an example to demonstrate the model test,and verify the optimization effect of ramp single control and ramp main line mixed control under the optimization effect.The results show that the conflict under ramp control is reduced by 52.5% and the vehicle delay is increased by 20.5% compared with the uncontrolled state.The conflict and vehi-cle delay under hybrid control are reduced by 68.1% and 12.0%,respectively.It can be seen that the control model has obvious opti-mization effect on ramp traffic safety and efficiency.One of the most effective control strategies is the ramp mainline mixed control,which leads to significant improvements in ramp traffic efficiency and traffic safety.关键词
