AI Technical Summary

Technical Problem

Existing technologies suffer from low traffic efficiency, insufficient control information transmission delay and reliability, rigid signal control mechanisms, conflicting authority among multiple traffic entities, and high system upgrade costs under shared right-of-way conditions, resulting in limited overall operational efficiency.

Method used

The intelligent rail transit system adopts a multi-system linkage green wave driving method. Real-time location and speed data are collected by the intelligent rail vehicle unit and uploaded to the station monitoring system via 5G communication network. Combined with the inertial navigation compensation module, the positioning accuracy is ensured. The station monitoring system determines whether the vehicle enters the intersection warning range and calculates the estimated arrival time. The traffic signal management system and the main traffic light control center perform hierarchical judgment of permissions and dynamically trigger green light acceleration operation to realize priority passage of intelligent rail transit vehicles.

Benefits of technology

It significantly improves the traffic efficiency and system stability of intelligent rail transit vehicles, reduces operation and maintenance costs, optimizes traffic order, achieves a reasonable allocation of right-of-way between intelligent rail transit vehicles and social vehicles and pedestrians, reduces energy consumption, and lowers the difficulty and cost of system deployment.

Abstract

The invention provides an intelligent rail green wave driving method and system based on multi-system linkage, relates to the technical field of intelligent rail traffic control, and solves the problem that the overall operation efficiency of a novel rail vehicle under shared right of way is limited. The method comprises the following steps: collecting real-time position and speed data of the intelligent rail vehicle, verifying the data by a station monitoring system, calculating the predicted intersection arrival time of the intelligent rail vehicle, and sending the predicted intersection arrival time to a traffic signal lamp management system; and the predicted intersection arrival time, the current corresponding signal lamp state and intersection traffic flow data are combined and uploaded to a total traffic light control center, and the total traffic light control center determines whether to trigger a green light acceleration operation or not through an authority grading judgment mode, calculates the green light acceleration duration during triggering, generates a green light acceleration instruction and issues the green light acceleration instruction to the corresponding traffic signal lamp. On the premise of guaranteeing the traffic safety of the intelligent rail, social vehicles and pedestrians, the traffic efficiency of the intelligent rail intersection is remarkably improved, the operation and maintenance cost is reduced, and the urban traffic operation order is optimized.
