Abstract:
Deaths due to traffic accidents became a major problem that expenses governments billions of Pounds. In case of highway accidents, acknowledgment to the proper authorities is highly needed. The main objective of this paper is to create a Real Time Traffic Accident Warning System (RTTAWS) using Wireless Sensor Network (WSN) and Radio-Frequency Identification (RFID) Technologies. This paper explains the hardware prototype setup for RTTAWS, the algorithms used, the advantages and the limitations of the entire system. Also the configuration of the setup and application software is elaborated. Sensors installed in a vehicle detect the accidentâ€™s location, the vehicleâ€™s speed just before the accident and the number of passengers in the vehicle. The sensors then send an alert signal to a monitoring station. The monitoring station, in turn, tracks the location where the accident has occurred and directs casualty alert to the authorities concerned.
