Design of emergency system for intelligent traffic system using VANET

Smart cities would like to plan how to minimize their transportation problems due to the increasing population that produces congested roads. VANETs (Vehicular Ad Hoc Networks) aim at helping to alleviate this issue improving vehicles´ mobility, increasing road safety and also seeking to have more sustainable cities. At the beginning of the development of vehicular technologies, the main goal was to have more efficient and safer roads. Nowadays, thanks to the huge development in wireless technologies and their application in vehicles, it´s possible to use Intelligent Transportation System (ITS) that will change our way to drive, improve road safety, and help emergency services. A survey of assorted Intelligent Traffic Systems (ITS) with respect to our proposed scheme is described in this paper. It introduces a new system consist of a smart city framework which has Intelligent Traffic Lights (ITLs) situated at every intersection that transmit information about traffic conditions and provide the driver congestion free shortest path in emergency that helps to take proper trip decisions.
