Advance left-turn traffic control method at road intersection section

Abstract

The present invention relates to a passing control method at a road intersection section, especially to a passing control method for left turn in advance at a road intersection section. A lane for left turn in advance is arranged on a road for controlling the straight and left-turning conflict traffic flow at an intersection; an X-shaped zebra crossing is arranged at the interior of the intersection for taking into account the passing paths for non-motor vehicles and pedestrians; the phase position and the phase sequence among the non-motor vehicles, the pedestrians and the vehicles are arranged to avoid the traffic conflict among the non-motor vehicles, the pedestrians and the vehicles; when the vehicles are passing, the non-motor vehicles and the pedestrians are banned from intersection; and when the non-motor vehicles and the pedestrians are passing, the vehicles are banned from intersection, and at the same time, the going-straight non-motor vehicles and the pedestrians can straight go to pass the intersection, and the turning-left non-motor vehicles and pedestrians directly turn left through the X-shaped zebra crossing at the interior of the intersection. When a lane for turning left in advance is designed at the road, the passing control method for left turn in advance at a road intersection section provides a passing method and a signal control measure for non-motor vehicles and pedestrians at the interior of the intersection so as to improve the passing efficiency of the non-motor vehicles and pedestrians at the interior of the intersection.

Description

technical field [0001] The invention relates to a traffic control method at a road intersection, in particular to a coordinated control method for the traffic of motor vehicles, non-motor vehicles and pedestrians at the road intersection under the design of a left-turn lane in advance of a road section. Background technique [0002] Urban road intersection is the bottleneck of urban road network operation, and also the key point of urban road traffic congestion. Reasonably organizing the passing space and passing order of each traffic flow can effectively improve the passing efficiency of the intersection. Among the traffic flows in various directions at urban road intersections, the conflict caused by left-turn traffic flow is the most serious, and it is also the focus of current scholars' research. Scholars have conducted extensive research on the setting conditions and methods of left-turn lanes, the setting of waiting areas for left-turns inside intersections, and the s...

Problems solved by technology

For the design of the reverse left-turn lane at the intersection of urban roads, if the traffic demand of non-motor vehicles and pedestrians is not considered, the practicability and feasibility of the design will be affected

None of the above documents considered the traffic organization and passing method of non-motor vehicles and pedestrians inside the intersection, nor did they consider the coordinated control method of the reverse left-turn phase of the road section when non-motor vehicles and pedestrians pass through the intersection, which is not in line with the requirements of urban road intersections in my country. The entrance has the characteristics of many non-motorized vehicles and pedestrians

In addition, the existing technology does not systematically analyze the calculation of the length of each part of the intersection entrance and exit when the left-turning vehicle uses the exit lane to turn left in the opposite direction.
