Intersection Traffic Control Method Considering Remaining Distance to Destination and Congestion of Next Road Segment

Abstract

In intelligent transportation systems (ITS), researches aimed to alleviate congestion and improve traffic flow are being conducted. This paper proposes intersection traffic control method considering remaining distance to destination and congestion of next road segment (ICDIC) for the purpose of improving the traffic capacity of the entire areas. In ICDIC, each vehicle transmits information about the remaining travel distance to the final destination and the next driving lane to roadside unit (RSU) installed at the intersection of the destination. The RSU classifies the vehicles for each driving lane based on the received information. The RSU calculates intersection traffic priority calculation for each vehicle based on the length of the remaining travel distance and the low congestion degree of the destination lane, and the priority of each lane are calculated by taking the average for each lane for each lane. For these processes, traffic capacity can be improved throughout the area.
