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 sto

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...

Abstract

The invention discloses a pre-signal control method for buses in the left-turn lane of a crossroad. The method comprises the following steps: 1, formulating driving rules of vehicles in each lane controlled by a pre-signal; 2, adjusting the signal timing of the pre-signal according to the signal timing of the main signal of the entrance lane of a crossroad; 3, determining the length of a waiting area for left-turn buses, the distance between a pre-signal parking line and a main signal parking line, and the location of a traffic guidance sign; 4, determining the time from the end of the pre-signal straight green light to the end of the main signal straight green light according to the position of the pre-signal stop line and the speed limit condition of the entrance lane; and 5, determiningthe time from the main signal left-turn green light turns on to the pre-signal left-turn green light turns on according to the position of the pre-signal stop line and the speed limit condition of the entrance lane. According to the pre-signal control method for buses in the left-turn lane of a crossroad, the problem of lane change of left-turn buses is solved, so that the traffic efficiency of the entrance lane of the crossroad is improved.

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...
