Apparatus and method for preventing collision of vehicle at crossroads
First Claim
1. An apparatus for preventing a collision of vehicles at a crossroad in a network environment configured with a plurality of sensor nodes installed on roads connected to the crossroad, the apparatus comprising:
- an information generating means installed at each road forming the crossroad for generating real-time vehicle information by integrating vehicles'"'"' information including a speed and a position provided from the vehicles on each of the roads to the plurality of sensor nodes on the roads and traffic sign information; and
an information collecting and providing means for providing the traffic sign information to the information generating means, collecting vehicles'"'"' information in real-time from the information generating means of a predetermined road near the crossroad, storing the collected information, and providing the collected information to vehicles approaching the crossroad through another road of the crossroad such that the vehicles can predict a collision occurring in a danger area located within the crossroad.

Abstract
An apparatus and method of preventing a collision of vehicle in a crossroad are disclosed. The apparatus includes: an information generating unit installed at each of roads near the crossroad for generating real-time vehicle information by integrating vehicle'"'"'s information including a speed and a position provided from the vehicles on each of the roads and traffic sign information; and an information collecting and providing unit for providing the traffic sign information to the information generating unit, collecting vehicles'"'"' information in real-time from the information providing means of a predetermined road near the crossroad, storing the collected information, and providing the collected information to vehicles approaching the crossroad through another roads for the vehicles to predict a collision in the crossroad.

8. A method for preventing a collision of vehicles at a crossroad, wherein the method comprising the steps of:
-
installing sensor nodes on a plurality of roads forming a crossroad and building a network environment between the sensor nodes; collecting traffic sign information of the crossroad in real time by the sensor node of a predetermined road, sensing a speed and a position of a vehicle on a corresponding road, and generating real-time vehicle information; providing traffic sign information of the crossroad from the sensor node to the vehicle, and predicting a traffic sign when the vehicle arrives at the crossroad by the vehicle; and collecting a message protocol type of real-time vehicle information at a base station, and providing the collected information to vehicles approaching the crossroad through other roads to predict a collision in a danger area of the crossroad. - View Dependent Claims (9, 10, 11, 12, 13)
