CAR-2-X and Pedestrian Safety

Traffic accidents involving pedestrians or cyclists cause thousands of fatalities and serious injuries every year. In this article, we present an innovative approach for a collision avoidance system that seeks to reduce these accidents. We also discuss the different architectural approaches utilizing ad hoc and/or cellular technologies and different processing setups and present a physical analysis of the system time available between detection, warning, and reaction to give an overview of the time constraint.
