A centralized real-time Advanced Driver Assistance System based on smartphones

This work leverages the wide diffusion of smartphones and existing cellular network to implement a centralized, real-time, Advanced Driver Assistance System. Each vehicle is equipped with a smartphone that periodically computes and sends vehicle's global position and speed through GPRS or UMTS network. The centralized server snaps all running vehicles into digital maps and implements safety algorithms to detect potential dangerous situations. The identification of a prospective crash generates a warning on the smartphone to alert the driver. This paper presents the general hardware and software architecture and the implementation of two use cases. An evaluation of the critical aspects of the system is also provided.
