网联环境下混合交通分配模型

Mixed Traffic Flow Assignment Model under Network Connected Environment

为了提高混合交通环境的路网通行效率,对存在城市CAV专用区域的情况下的混合交通分配进行了研究。本文在混合交通环境的背景下,考虑混合交通具有不同的路由准则,因此构建了相应的混合交通分配模型,通过设置CAV专用区域提升系统通行效率和CAV车辆使用率,采用SRA算法求解。最后进行了算例分析,通过结果可以看出,设置CAV专用区域可以将系统通行效率提升26%,当CAV车辆系统服从率为1,相比于系统服从率为0.8时,系统通行效率提升6%。

To improve the efficiency of road traffic network in mixed traffic environment,mixed traffic allocation in the presence of urban CAV is area.In the context of mixed traffic environment,the mixed traffic has different routing criteria,so the corresponding mixed traffic allocation model is constructed.SRA algorithm is used to improve the traffic efficiency of CAV dedicated area and CAV vehicle usage.Finally,the example analysis is conducted.It can be seen that setting the CAV special area can improve the system traffic efficiency by 26%.When the CAV vehicle system obedience rate is 1,the system traffic rate can be improved by 6%compared with the system obedience rate of 0.8.
