Problems solved by technology

In measure 1, if there are a lot of left-turning social vehicles in the morning and evening rush hour, the left-turning BRT may not be able to pass the intersection within one signal cycle, and the delay will be greatly increased; in measure 2, the left-turning BRT will conflict with oncoming straight vehicles , affecting the operational efficiency of intersections and increasing potential safety hazards

Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings.

[0039] A kind of intersection design method of the traffic method of the left-turn BRT passing through the intersection, the intersection design scheme figure of an embodiment of the present invention is as follows figure 1 shown.

[0040] Step 1. Set the coming section of BRT as section I, the section on the right side of intersection section I as section II, the opposite section as section III, and the left section as section IV; widen the entrance road of section I and set it at the beginning of the widening gradient section Special signal lights for left-turn buses, and left-turn bus detectors are installed at the beginning of the widening section;

[0041]In this embodiment, the section with straight-going BRT lines and left-turning BRT lines is the west section I, the south section is section II, the east section is section III, and the north section is section ...

Abstract

The invention aims at a bus rapid transit coming road which comprises a straight bus route besides a left-turn line. Meanwhile, an intersection is provided, wherein a bus rapid transit coming right road of the intersection has a medial strip, and the overall width of a motor vehicle lane plus the width of the medial strip is larger than or equal to 25 meters. The invention provides a left-turn bus rapid transit passing-through method, intersection design matched with the method and a signal control method, wherein the left-turn bus rapid transit passing-through method enables left-turn bus rapid transits to turn right and turn around to pass through the intersection according to a special phase indication or to turn left to pass through the intersection by utilizing a straight bus transit lane. According to the technical scheme, average delay time of the left-turn bus rapid transits passing through the intersection is shortened, the left-turn bus rapid transits can pass through the intersection in a signal cycle time period after reaching the intersection, and conflicts between the left-turn bus rapid transits and opposite straight social vehicles can be eliminated.

Description

technical field [0001] The invention relates to the technical field of traffic design and control, in particular to an intersection that reduces delays and conflicts of left-turn rapid transit buses, a passing method and a signal control method for the intersection. Background technique [0002] With the continuous advancement of my country's urbanization process, the traffic problem is rapidly becoming one of the major problems restricting the development of my country's urban economy. In view of the characteristics of my country's highly dense urban population and limited road space resources, BRT, which has large transportation volume, fast and convenient, low energy consumption and pollution, and occupies less road space resources per capita, has become an effective measure to alleviate the severe traffic situation in my country. According to many definitions of BRT in foreign theoretical circles, combined with China's national conditions, the Ministry of Construction No...
