摘　　要：文中基于混合交通组队策略,针对合流区车辆合流特性,构建混合交通流环境下的合流区多车协同决策机制.搭建混合交通合流仿真环境,验证多车协同方法有效性.结果表明:与匝道自由合流控制相比,文中提出的方法在当网联车辆渗透率高于40%~60%时,车辆平均行驶时间的优化率增幅加快,随着渗透率增高,效果最高改善了22.42%,且总平均延误、总冲突数分别减少了14.5%、21.1%,匝道延误平均减少了36.3%.Based on the mixed traffic team strategy,a multi-vehicle cooperative decision-making mechanism in the confluence area was constructed in view of the confluence characteristics of vehicles in the confluence area.The simulation environment of mixed traffic confluence was built to verify the effectiveness of multi-vehicle coordination method.The results show that,compared with on-ramp free confluence control,the optimization rate of average vehicle travel time increases faster when the penetration rate of networked vehicles is higher than 40%~60%.With the increase of permeability,the maximum effect is improved by 22.42%,and the total average delay and the total number of conflicts are reduced by 14.5%and 21.1%respectively,and the ramp delay is reduced by 36.3%on average.
