Wireless sensor system for warning unexpected danger

The main reason for the car accident is driver's delay in recognition anderror in operation and judgment about danger. In order to solve the safety problem, a wireless sensor system is proposed. The real time informationand possible danger ahead is detected by wireless sensor systems installed along the road and then, provided just immediately before an accident caused. In the consideration of environment in which the system is deployed,the wireless sensor system for safety is composed of wireless sensor nodesensing car existence, wireless relay node relaying the sensed data, and base station gathering all sensed data from sensor node and generating alarm messages. The system provides accurate vehicle sensing, cost effective construction, low power consumption and real time data delivery. It is expected that the system successfully reduces car accidents with wireless sensor network technology. For the covering abstract see ITRD E140665.
