Embodiment 1

[0052] Such as figure 1 Shown, a kind of intersection bus turn left priority road based on reverse variable lane, the road entry and exit lanes of the intersection bus entrance lane direction are each 4 lanes, and the entrance and exit lanes of intersecting roads are each 3 lanes; Also includes:

[0053] The reverse variable lane 1 is set on the leftmost lane of the road exit in the direction of the intersection bus entrance lane;

[0054] The left-turn bus lane 9 is arranged on the leftmost lane of the road entrance road near the intersection bus entrance lane direction, and the front end of the left-turn bus lane 9 passes through the tail of the gradient road section 11 and the reverse variable lane 1. terminal connection;

[0055] The first special signal light 6 and the first sign 7 that guide the left-turn bus to enter the reverse variable lane 1 are arranged at the junction of the left-turn bus lane 9 and the reverse variable lane 1 and are close to the reverse variabl...

Embodiment 2

[0067] Such as figure 2 As shown, a method for priority control of bus left turns at intersections based on reverse variable lanes, including steps:

[0068] 1) Set the signal phase sequence at the intersection, where the direction of the entrance of the left-turning bus lane 9 is set as this direction, then the first phase is the left-turning phase in this direction, the second phase is the straight-going phase in this direction, and the third phase It is the left-turning phase in the intersecting direction, and the fourth phase is the straight-going phase in the intersecting direction;

[0069] 2) When the green light of the second phase starts, the first special signal light 6 shows a red light, and the second special signal light 3 shows a green light. At this time, the left-turn bus queues up before the stop line of the left-turn bus lane 9;

[0070] 3) Start the first video detection system 8 on the left-turn bus lane 9 10s before the end of the green light of the seco...

Abstract

The invention discloses a left-turn bus priority road at an intersection based on a reverse variable lane, comprising: a reverse variable lane, a left-turn bus dedicated lane, a first special signal light for guiding a left-turn bus into the reverse-variable lane, and a second A sign, a first video detection system, a second video detection system, a second dedicated signal light and a second sign, a third sign, a fourth sign, and a signal control unit. The invention also discloses a method for managing and controlling the left-turn priority road of the bus at the intersection. By detecting the number of buses on the left-turn bus lane and the position of the vehicle closest to the stop line on the reverse variable lane, the vehicle is calculated. By reversing the time required for the variable lane, the processing result is transmitted to the signal control unit to generate a new control scheme. The invention further reduces the per capita delay at the intersection and improves the operation efficiency of the bus fleet, effectively optimizes the bus priority measures and reduces the waste of road resources at the intersection.

Description

technical field [0001] The invention belongs to the field of road traffic control, and relates to a bus left-turn priority road at an intersection based on reverse variable lanes and a control method. Background technique [0002] As the number of cars in cities continues to increase, traffic congestion in big cities is becoming more and more serious. [0003] And vigorously developing public transportation is one of the best solutions to solve traffic congestion. Public transport priority is an effective solution with low investment, quick results and green environmental protection, and the country's emphasis on public transport priority is constantly increasing. At present, public transportation priority measures include intersection bus priority and road section bus priority. Intersection bus priority mainly includes optimizing intersection signal control and providing special phases for bus entrance lanes at intersections. Road section bus priority includes dedicated la...
