Crossroads risk assessment using GPS and inter-vehicle communications

Recent developments in inter-vehicle communications (IVC) focus on the conception of suitable hardware and communications protocols. We contribute to this effort by analysing the performance of IVC through a vehicular application approach. The study aims to measure the contribution of IVC in comparison with traditional safety sensors on an advanced driver assistance scheme (ADAS) system. We choose to study the risk assessment in crossroads approaching. The system is based on a standard 802.11 technology combined to a standard low-cost GPS receiver. The performance is analysed regarding the application showing the feasibility of the system and its integration on board our prototype LARA
