Problems solved by technology
Left-turning buses interweave with straight-going and right-turning vehicles. This weaving is a complex C-shaped weaving. When the flow of left-turning buses is relatively large, it will seriously affect the running speed of straight-going and right-turning vehicles. Steering vehicles stop and go, which not only reduces the traffic efficiency at the intersection, but also causes dissatisfaction and irritability for drivers and passengers
How to effectively manage and control intersections with large traffic flow of left-turning buses, there is currently no effective solution

Embodiment Construction
[0063] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0064] combine Figure 1-Figure 4 Illustrate the present embodiment, the present invention proposes a kind of intersection to stop the bus left change lane pre-signal control method, as figure 1 As shown, the passage rules of right-turning vehicles under the control of the pre-signal and main signal are consistent with those of straight-going vehicles, and right-turning vehicles are classified as straight-going vehicles, so the following content do...

The present invention proposes a pre-signal control method for buses stopping on the left side of an intersection, comprising the following steps: 1. Prescribing the operating rules of vehicles in each lane controlled by the pre-signal; Coordinate the signal timing of the pre-signal; 3. Determine the length of the left-turn bus waiting area, the distance between the pre-signal stop line and the main signal stop line, and the location of traffic guidance signs; 4. According to the position of the pre-signal stop line and the speed limit conditions of the entrance road, Determine the length of time that the main signal straight-going green light lags behind the pre-signal straight-going green light; 5. According to the position of the pre-signal stop line and the speed limit conditions of the entrance road, determine the time period when the main signal turn left green light is turned on ahead of the pre-signal turn left green light. The invention solves the problem of safe lane changing of left-turning buses, thereby improving the traffic efficiency of the entrance road at the intersection.
Description
technical field [0001] The invention belongs to the technical fields of traffic engineering and traffic management and control, and in particular relates to a pre-signal control method for buses stopping at intersections to change lanes to the left. Background technique [0002] In recent years, with the rapid development of my country's economy and society, the number of urban motor vehicles has increased sharply, and the shortage of roads has made urban roads more and more congested. As an important part of the traffic system, urban intersections become the key to restricting road traffic capacity. At present, the function of public transportation in urban passenger transportation is becoming more and more important. Implementing the public transportation priority strategy at urban intersections can not only alleviate urban traffic congestion, but also promote the sustainable development of urban transportation. While the rapid development of urban public transport brings...
