Sand-dust environment affects drivers' perceptions of surrounding traffic conditions, resulting in unsafe operations. From an ergonomics perspective, such adverse effects could be alleviated by environment control as well as the assistance of machines. Vehicle-to-vehicle (V2V) communication appears to be an important component of machines in future traffic systems, which could support the driving task. In order to explore what influences V2V communication would generate on traffic systems, this paper proposes a car-following model accounting for V2V communication in a sand-dust environment. The results indicate that V2V communication helps to reduce the fluctuations of acceleration, headway, and velocity, when a small perturbation is added to the traffic flow in sand-dust environment. If a vehicle in the traffic flow stops suddenly, the number of crumped vehicles decreases with V2V communication taken into account. Furthermore, the residual velocities of the crumped vehicles decrease, which means the severity of collision is suppressed. It is concluded that V2V communication can play an active role in the improvement of traffic safety in a sand-dust environment.
沙尘环境会影响驾驶员对周围交通状况的感知，从而导致操作不安全。从人体工程学的角度来看，可以通过环境控制以及机器的辅助来减轻这种不利影响。车对车（V2V）通信似乎是未来交通系统中机器的一个重要组成部分，可以支持驾驶任务。为了探究 V2V 通信会对交通系统产生什么影响，本文提出了一种考虑沙尘环境中 V2V 通信的跟驰模型。结果表明，当在沙尘环境中的交通流中加入小的扰动时，V2V 通信有助于减少加速度、车头时距和速度的波动。如果交通流中的一辆车突然停止，考虑到 V2V 通信，崩溃车辆的数量会减少。此外，崩溃车辆的残余速度会降低，这意味着碰撞的严重程度会受到抑制。结论是，V2V 通信可以在改善沙尘环境中的交通安全方面发挥积极作用。
