Event traffic detection using heterogenous wireless sensors network

Deaths due to traffic accidents is a major problem in several countries principally because of the fact that emergency actions are not provided at the place of accident at required time, Basically, in the event of a road accident, a real time traffic accident detection system can intelligently inform the site of accident, reporting it to the proper authorities, informing about the number of injured people so that the type and the amount of emergency services needed can be provided. This paper aims to introduce an approach to the traffic event detection, especially in highways, by the means of heterogeneous WSNs (using unmanned aerial vehicles called UAVs, vehicular sensors, smartphones and ground WSNs). The work includes a system overview and the proposed event detection approach.
