信控进口道异质交通流换道控制策略OA

To reduce the negative impact of vehicle lane-changing on the traffic flow operation of entrance lane,the lane-changing control strategy of heterogeneous traffic flow at the signalized control entrance lane was proposed.The traffic flow was analyzed,and the function area of entrance lane was divided to construct the virtual lane-changing area.The influence factors on vehicle lane-changing were analyzed,and the lane-changing control strategy of heterogeneous traffic flow based on virtual lane-changing zone was proposed.The traffic flow model of cellular automata was built,and the following rules were determined.Taking the traffic flow speed as evaluation index,the simulation analysis under different entering probability environment was carried out,and the lane-changing strategy was verified based on the virtual lane-changing area.The results show that the optimal length of virtual lane-changing zone is 150 m,and the key control point of the entering probability of the lane-changing strategy under the optimal length of virtual lane-changing zone is 0.5.Compared with the traditional lane-changing strategy,when the entering probability is greater than or equal to 0.5,the lane-changing strategy based on the virtual lane-changing zone can increase the running speed of traffic flow by 32.61％.On the contrary,the effect of traditional lane-changing strategy is better.
