摘　　要：高速公路合流区是事故的多发区域,车联网技术为提高合流区的安全提供了有效的手段。提出了一种新的车联网环境下合流区的车辆控制协调方法。首先,对合流区的安全隐患进行了分析。其次,针对货运车辆的行驶特点,计算了匝道大货车到达合流区冲突区域的时间范围,以此时间段为约束条件,计算了主路车辆在同一时间段到达合流区的速度区间。在考虑安全和效率的条件下选择最优主路车速值,通过对车辆进行预警,使主路车辆避开可能发生冲突的区域。最后,利用仿真软件Vissim二次开发了车车通信模块,从安全性、通行效率等指标评价了安全协调控制效果。Merge area on expressway is the area with more accidents, and the technology of the connected vehicles provided an effective way to improve the safety of the merge area. A new method for coordinated controlling vehicles in merge area in connected vehicle environment is proposed. First, the potential safety hazard in merge area is analyzed. Second, the time range of ramp truck reaches the merge area is calculated according to the characteristics of freight vehicles. Using the same time range as the constraint, the speed range of main road vehicle reaches the merge area is calculated. Selecting the optimal main road vehicle speed in term of safety and efficiency, the main road vehicle is warned to avoid the possible conflict area. At last, the V2V communication module is developed by using the simulation software Vissim, and the effect of safety coordinated control is evaluated in aspects of safety and traffic efficiency.
