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 comparing:
- an information generating means 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 means for providing the traffic sign information to the information generating means, 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:
-
a) installing sensor nodes on each of roads and building a network environment between the sensor nodes;
b) 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 vehicle on a corresponding road, and generating real-time vehicle information;
c) 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
d) 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 the crossroad. - View Dependent Claims (9, 10, 11, 12, 13)
