A traffic control method and device

Abstract

The invention discloses a traffic control method and a traffic control device. The traffic control method comprises the steps of determining an average vehicle distance between each vehicle and a front vehicle in a preset time length of a traffic control area based on vehicle information reported by each vehicle in the preset time length of the traffic control area that corresponds with a target traffic lamp; determining whether the average vehicle distance is smaller than a preset vehicle distance; if yes, determining a first traffic volume in passing through the target traffic lamp in the preset time length of the traffic control area based on the number of vehicles which report the vehicle information in the preset time length of the traffic control area and the vehicle type informationcarried in the vehicle information; and based on the first traffic volume, setting the control period of the target traffic lamp, thereby realizing traffic controlling. According to the traffic control method and the traffic control device, a traffic signal control period is updated according to the dynamic traffic volume, thereby more reasonably controlling the operation time of the traffic lamps in different directions and ensuring ordered passing of the vehicles at a crossing.

Description

technical field [0001] The invention relates to the technical field of traffic control, in particular to a traffic control method and device. Background technique [0002] With the maturity of autonomous driving technology, self-driving cars or smart cars have been able to meet the needs of autonomous navigation in many cases. Not enough, can not meet the security requirements. However, with the arrival of the fifth-generation mobile communication technology 5G, due to its low-latency, high-reliability wireless transmission characteristics, and information interaction based on wireless communication networks, vehicles can obtain other macro driving information that is difficult to obtain by means of sensors, which can realize Information sharing between vehicles. [0003] At present, the timing of traffic lights adopts the Webster timing method, and the formula is as follows: [0004] The calculation formula (Webster equation) of the traffic signal control period of a sin...

AI Technical Summary

Problems solved by technology

The acquisition of the V value requires manual statistics and cannot be obtained in real time, so the C value generally adopts a fixed value

Moreover, in the process of manually counting V, only the number of vehicles is counted, regardless of the difference in vehicle size, which will also lead to low statistical accuracy of the V value and cause traffic congestion.
