Study on Perception and Communication Systems for Safety of Vulnerable Road Users

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 Global Positioning System (GPS) data. Since perception and communication have complementary features, one can expect that a combination of such approaches can be a solution to the VRU safety. This is the motivation of the current work. The authors 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. The authors' 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, the authors propose a cooperative system that combines the outputs of the communication and perception systems.
