Setting method for far guidance of road intersection minor road

Abstract

The invention discloses a setting method for far guidance of a road intersection minor road, and belongs to the field of traffic control and traffic design. The used technical solution is that, in theintersection in which the grades of the intersected roads have the difference, the far guidance is performed to the minor road traffic stream, a traditional intersection organization mode is used forthe main road traffic stream, and far guidance geometrical parameters of the road intersection minor road are determined by calculating. The method specifically comprises the following steps: 1) determining the distance from the direction change position of the far guidance traffic stream to the intersection; and 2) determining the queuing lane length of the far guidance direction change trafficstream. Through the delay comparison of intersection vehicles before and after the far guidance, the far guidance channelization design of the minor road is proved to effectively reduce the vehicle average delay, relieve the traffic jam, and improve the operating efficiency of the intersection.

Description

technical field [0001] The invention relates to the field of traffic control methods, in particular to a method for setting the secondary road fare at road level intersections. Background technique [0002] With the continuous acceleration of urbanization in recent years, cities are facing increasingly serious traffic congestion problems. In the road traffic system, the intersection is the node of the road network, and it is often the "bottleneck" of traffic flow, which is the main point causing traffic delay. According to statistics, in the urban road network, the time of vehicles at the intersection accounts for about 30% of the whole time. Due to the large number of conflicts such as merging, diverging, and crossing caused by the traffic flow in all directions at the intersection, the intersection becomes a place where accidents frequently occur. According to statistics, 60% of traffic accidents on urban roads occur at intersections. How to reduce traffic conflicts at i...

Problems solved by technology

However, at present, there is a lack of systematic research on left-turning and far-distance intersections at level intersections, and the determination of the U-turn position of left-turning vehicles is still relatively vague. Quantitative calculation
