Abstract

The invention discloses a method and system for conflict resolution of a non-signalized intersection. The system comprises a first electronic tag reader set, a second electronic tag reader set, data processing units, a road side release device and a vehicle-mounted audio broadcasting device. The system acquires travel information of vehicles heading for the intersection through the first electronic tag reader set and the second electronic tag reader set, predicts conflict between vehicles according to the vehicle travel information by means of the two data processing units, proposes the conflict resolution method, reminds vehicles coming from afar through the road side release device, and conducts conflict resolution guidance on vehicles entering the intersection through the vehicle-mounted audio broadcasting device, and therefore the safety of the non-signalized intersection can be effectively improved.

Description

technical field [0001] The invention relates to a conflict resolution method and system for an unsignalized intersection. Based on Electronic Vehicle Identification (EVI), the system judges potential conflicts through acquired vehicle driving information and motion status, and belongs to the field of intelligent transportation. Background technique [0002] Electronic license plate recognition technology is the extension and improvement of radio frequency identification technology. Using the electronic license plate label installed on the motor vehicle, when it passes through the road section equipped with radio frequency identification reader, the data on the electronic license plate is collected to achieve traffic management, The purpose of traffic forecasting and control, traffic guidance. Electronic license plate recognition technology can break through the bottleneck of the original traffic information collection technology, and realize the classified and accurate coll...
