SYSTEM AND METHOD FOR PROVIDING VEHICULAR SAFETY SERVICE
First Claim
1. A method for providing a vehicular safety service to a vehicle terminal of a vehicle located on a road in a service area from a local server, the method comprising:
- receiving road surface state information of each zone of a road in the service area from a road sensor;
receiving location information and running information from the vehicle terminal;
estimating an inter-vehicle safe distance situation based on the road surface status information of each zone of the road, the location information, and running information from the vehicle terminal; and
if an inter-vehicle safe distance is determined to be inadequate according to the inter-vehicle safe distance situation, transmitting safe distance risk information to the vehicle terminal.

Abstract
A local server of a system for providing a vehicular safety service receives road surface state information of each zone of the road in a service area from at least one road sensor located in the service area to calculate a road safety coefficient of each zone, and receives location information and running information of a vehicle from at least one vehicle terminal located in the service area to calculate a traffic flow analysis coefficient. The local server provides a vehicular safety service to a vehicle terminal by using the road safety coefficient of each zone and the traffic flow analysis coefficient.
