论文摘要
车辆越来越多地建立联系，短期无线通信承诺将引入驾驶员行为的根本性变化。在主要用例中，相交管理肯定是可能主要影响交通安全和效率的一种。在这项工作中，我们考虑了一个交叉点碰撞警告应用程序，并利用硬件（HIL）平台来验证对事故风险的影响以及平均旅行距离的时间。除了包含真正的ITS-G5符合消息交换外，该平台还包括一个带有真实信号的频道模拟器。结果表明，碰撞风险可以大大降低，安全性和交通效率之间的总体权衡。同时，结果表明，实际通道条件的存在不能保证与理想通道传播相同的零风险条件，从而指出了通道条件和信号处理的重要性。
Vehicles are increasingly becoming connected and short-range wireless communications promise to introduce a radical change in the drivers' behaviors. Among the main use cases, the intersection management is surely one of those that could mostly impact on both traffic safety and efficiency. In this work, we consider an intersection collision warning application and exploit an hardware-in-the-loop (HIL) platform to verify the impact on the risk of accidents as well as the average time to travel a given distance. Besides including real ITS-G5 compliant message exchanges, the platform also includes a channel emulator with real signals. Results show that the risk of collisions can be drastically reduced, with an overall trade-off between safety and traffic efficiency. At the same time, it is shown that the presence of real channel conditions cannot guarantee the same condition of zero-risk as with ideal channel propagation, remarking the importance of channel conditions and signal processing.
