Problems solved by technology

At present, the main problem that affects the use of bus-only lanes at intersections is that when the intersection exits are congested, social vehicles follow up with green lights, causing congestion in the intersection area, and traffic cannot operate
Taking roads with dedicated bus lanes at road sections and intersections as an example, buses driving in the dedicated lanes can ensure that they have priority in road sections and intersection entrances, but the actual situation is that when the intersection exits congestion , the traffic signal has not changed, and social vehicles drive into the congested exit road, causing congestion in the intersection area, and vehicles in all directions are unable to pass, resulting in the inability of public transportation priority facilities to function, and public transportation vehicles cannot pass

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] Step 1: According to the method of determining the congestion detection distance, determine the congestion warning position L downstream of the intersection exit j (j=1,2,...,J) j , where J is the total number of exits; and a detection device is installed at the congestion warning position downstream of the intersection exit j,

[0035] Step 2: Set up two sets of intersection signal lights at the intersection, one set is an arrow signal light, used to control the passage of social vehicles; the other set is a square signal light, used to control the passage of public transport vehicles on the bus lane; among them, the set serves for social vehicles Under normal conditions, the signal lights are implemented according to the preset signal timing scheme, and under abnormal conditions, the signal timing scheme is adjusted in real time; the signal lights serving publ...

Abstract

The invention relates to an intersection signal control method based on public transport priority. According to the method, intersection lane arranging information and real-time traffic flow information of all entrance passages are considered and combined with a vehicle jamming detection device and two groups of intersection signal lamps, a detector is triggered when an exit passage of an intersection is in a jamming state, an intervention signal control scheme is generated through automatic control of a computer to ensure timely stopping of social vehicles, a jamming area is prevented from spreading to the interior area of the intersection to affect traffic of the other direction, and at the same time public transportation vehicles are allowed to continue to run in a public transportation lane to ensure the public transport priority. Therefore, jamming of downstream road sections is prevented from affecting traffic of the intersection near upstream in an urban road peak traffic hour or when an sudden accident happens, influence of traffic jam on irrelevant traffic flow of the intersection is reduced, the public transport priority is guaranteed at the same time, and traffic circulation efficiency of a road network is improved. The invention belongs to the technical field of traffic signal control.

Description

technical field [0001] The invention relates to considering the layout of intersection lanes and the real-time traffic flow information of each entrance road, combined with a vehicle congestion detection device and two sets of intersection signal lights, triggering a detector when congestion occurs at an intersection exit road, and automatically controlling by a computer to generate Intervention signal control scheme to ensure that social vehicles can stop in time, avoid the congested area from spreading to the interior of the intersection, and affect the passage of traffic in other directions. In the event of unexpected accidents, avoid the congestion of the downstream section from affecting the traffic operation of the upstream intersection, reduce the impact of traffic congestion on the road network, and at the same time ensure the priority of public transportation and improve the traffic operation efficiency of the road network. The utility model belongs to the technical f...
