Traffic guidance system for urban underground road intersection

Abstract

The invention relates to the technical field of traffic guidance systems, and discloses a traffic guidance system for urban underground road intersections, which comprises an information processing module, a detection module and a guidance module, the detection module is arranged at an entrance and exit lane of an underground road intersection and is used for detecting vehicle passing information and speed information so as to transmit information to the information processing module; the information processing module stores all space information of the underground road and is used for receiving information of the detection module and processing and issuing the information; and the guidance module comprises a wireless network module, a control circuit and a display module, the guidance module receives the instruction of the information processing module, and the instruction is displayed in the guidance module. The system provides incoming vehicle guidance and driving indication of the intersection, detects and evaluates the congestion condition of the intersection, and induces the vehicles to safely and efficiently pass through the underground road.

Description

technical field [0001] The invention relates to the field of traffic guidance systems, in particular to a traffic guidance system for urban underground road intersections. Background technique [0002] At present, most of the underground roads built in major cities are systematic ring-shaped one-way roads, and the traffic organization form at the intersection of the basement entrance and exit of the plots along the line and the junction of the underground road is right-in and right-out. The regional underground roads are linear, connecting the basements of the plots along the line, and the two ends are connected with the main and secondary arterial roads of the city. They are set up as two-way two-lane lanes, and the intersection between the entrance and exit of the basement and the underground road is in the shape of a "T" or "ten". There are potential safety hazards at zigzag intersections, intersection sight distance and steering, and there is a lack of relevant research ...

AI Technical Summary

Problems solved by technology

The "Code for Setting Up Urban Underground Road Traffic Signs and Markings" promulgated in 2018 mostly focuses on the setting of entrances and exits, merging points and diverging points of underground roads, and lacks traffic guidance research on dangerous points such as left-turn intersections
