Embodiment Construction

[0110] This part of the content introduces in detail the setting method of the road level intersection secondary road of the present invention in conjunction with examples, such as figure 2 shown, including the following steps:

[0111] Step 1 The original intersection information collection, including: the number of entrances and exits in each direction; the width of the median; the original signal cycle of the intersection; the traffic volume in each direction during the peak period of the intersection.

[0112] Table 1 Intersection Peak Hour Traffic

[0113]

[0114]Step 2: traffic organization method of the secondary road at the level intersection: if figure 1 , the operation of the intersection adopts two-phase signal control (vehicles turning right are not controlled by signals), and the operation of vehicles on the main road is similar to that of conventional signalized intersections, that is, there is one phase for going straight on the main road and one phase for...

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...
