Extending The Scope Of Vehicular Ad-Hoc Networks In Order To Protect Vulnerable Road Users

Vehicle to Infrastructure (V2I) and Vehicle to Vehicle (V2V) communications networks can support applications that increase traffic safety and efficiency. This paper reports on a strategy to extend the scope of vehicular ad-hoc communication networks in order to protect vulnerable road users, notably motocyclists and pedestrians. While motorcycles will use primarily the same technology as other vehicles, there are so far few considerations about how to include pedestrians and cyclists in the vehicular communication scenario. The authors propose a self-contained, communication-based system for the protection of vulnerable road users. The harmonized distributed approach for the protection of vulnerable road users is comprised of a Central Information Database that covers the recognition of black spots and information about crossing pedestrians, school areas, bicycle paths, bus stops etc.; local Road Side Unit (RSU) systems that provide incoming vehicles with information related to vulnerable road users; and equipment for the Road User that can enable the interaction with surrounding vehicles and RSUs. The system shall only broadcast related warning messages in case the system detects an increased risk for the collision with a surrounding vehicle. In urban scenarios with crowded pavements there is a high probability that several devices will evaluate such increased risk at the same time. The paper also defines specific algorithms for the protection of cyclists and pedestrians. The authors stress that, in order to ensure compatibility with future vehicular ad-hoc networks the system has to reflect the specifications and recommendations of the C2C-CC, which aims to globally harmonize related standards.
