现有的保护易受伤害道路用户(VRU)的研发工作主要基于感知技术，旨在利用车载传感器来检测VRU。这种技术的效率在很大程度上受传感器能见度的影响。车辆对行人(V2P)通信也可以通过允许车辆和行人交换信息来促进VRU的安全。然而，这种解决方案在很大程度上受到交换信息的可靠性的影响，最常见的是GPS数据。由于感知和通信具有互补的功能，我们可以预期这些方法的组合可以成为VRU安全的解决方案。这是当前工作的动力所在。我们开发了理论模型来呈现感知和通信系统的特征。通过实验研究，比较了这些技术在真实环境中的性能。实验结果表明，在视距(LOS)条件下，该感知系统能够可靠地检测出50米范围内的行人和其他物体。相比之下，V2P通信覆盖范围在LOS和非LOS(NLOS)条件下分别约为340米和200米。然而，基于通信的系统无法正确定位车辆的VRU W.r.t，使系统无法满足安全要求。最后，我们提出了一种将通信系统和感知系统的输出相结合的协作系统。
The existing R&D efforts for protecting vulnerable road users (VRU) are mainly based on perception techniques, which aim to detect VRUs utilizing vehicle embedded sensors. The efficiency of such a technique is largely affected by the sensor's visibility condition. Vehicle-to-Pedestrian (V2P) communication can also contribute to the VRU safety by allowing vehicles and pedestrians to exchange information. This solution is, however, largely affected by the reliability of the exchanged information, which most generally is the GPS data. Since perception and communication have complementary features, we can expect that a combination of such approaches can be a solution to the VRU safety. This is the motivation of the current work. We develop theoretical models to present the characteristics of perception and communications systems. Experimental studies are conducted to compare the performances of these techniques in real-world environments. Our results show that the perception system reliably detects pedestrians and other objects within 50 m of range in the line-of-sight (LOS) condition. In contrast, the V2P communication coverage is approximately 340 and 200 meters in LOS and non-LOS (NLOS) conditions, respectively. However, the communication-based system fails to correctly position the VRU w.r.t the vehicle, preventing the system from meeting the safety requirement. Finally, we propose a cooperative system that combines the outputs of the communication and perception systems.
