Arterial street road-side traffic confluence signal control device and method

Abstract

The present invention provides an arterial street road-side traffic confluence signal control device and method. The arterial street road-side traffic confluence signal control device comprises confluence signal lights, an artery caution signal light and a confluence indicator, wherein the confluence signal lights are arranged in front of a vehicle stop line of a confluence intersection, the artery caution signal light is arranged at the connection position of the confluence intersection and an artery, and the confluence indicator is arranged in front of the confluence intersection; the confluence signal lights comprise a red light and a green light, and the signal cycle of the confluence signal lights is same as that of the upstream intersection signal lights of the artery; the green light is delayed a time t to start after the red light of the upstream intersection signal lights is started and continues until the red light of the upstream intersection signal lights is ended, and the red light works at the other time periods within the signal cycle. According to the present invention, by utilizing an arterial street traffic circulation rule, and adopting the signals to control and manage the arterial street road-side passageway traffic confluence, the influence of the road-side passageway traffic on the arterial streets and the urban traffic accident rate can be reduced, and the artery traffic efficiency is improved.

Description

technical field [0001] The invention belongs to the field of traffic design and signal control, and in particular relates to a traffic merge signal control device and method on the side of an urban arterial road. Background technique [0002] With the improvement of the living standards of Chinese residents, the number of cars is also increasing. The contradiction between the increasing number of motor vehicles and the slow construction of traffic infrastructure has caused more and more serious urban traffic problems. In the urban transportation system, the urban main road has a high traffic capacity, bears the main traffic flow of the city, and is the artery of the urban transportation system. Therefore, the operation status of urban arterial traffic determines the efficiency and safety of the entire urban traffic system. The urban road traffic network is a dynamic and complex system. The development of the urban economy has gradually increased the land development on both...

AI Technical Summary

Problems solved by technology

The traffic flow characteristics of roadside entrances and exits are mainly that the randomness of vehicles passing through is relatively large, and the speed of vehicles is relatively slow. Even the side entrances and exits of some urban arterial roads block the driver's sight because of their road greening facilities, seriously hindering the driver's observation of the entrances and exits or the vehicles passing through the arterial road, causing collision accidents between the entrance and exit vehicles and arterial road vehicles

[0004] The existing urban traffic signal control is mainly aimed at road intersections, and the control of the side entrances and exits of urban arterial roads mainly adopts the forms of traffic channelization and setting warning signs, etc. These methods cannot well reduce their impact on urban arterial road traffic
