Cooperative Safety: a Combination of Multiple Technologies

Governmental Transportation Authorities´ interest in Car to Car and Car to Infrastructure has grown dramatically over the last few years in order to increase the road safety and reduce traffic emission. The achievement of these objectives is subject to development of three aspects: Transmission, Localization and Sensor Networks. New wireless technique evolved form current WiFi technology shall be able to curb down the timing latency to achieve timely and efficient communication among vehicles. Relative positioning is essential to predict whether two cars are on route of collision. Experts estimate that positioning accuracy must be below one meter in order to provide the necessary reaction time. Many technical issues exist in this field as current GPS solutions do not provide this level of accuracy. There are multiple standalone approaches existing for sensing networks including imaging, radar and lidar. In order to create fault tolerant SIL3 compliant systems, data fusion is obligatory. The amalgamation of these different data streams requires powerful multicore processing to recognize and react to multiple concurrent scenarios.
