Problems solved by technology

At present, there is a lack of research on the combination of intersection signal control and direction-changing traffic technology to alleviate tidal traffic congestion, and there is no theoretical method for the steering function of each lane when the number of two-way lanes is adjusted.

Embodiment Construction

[0062] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0063] For urban arterial roads with tidal traffic, first calculate the non-uniformity coefficient K of the traffic volume direction D ; Then determine whether the setting conditions for changing direction traffic are satisfied: if the setting conditions for changing direction traffic are satisfied, the number of variable lanes is determined by calculation;

[0065]

[0066] The phase schemes of each signal in the table are shown in figure 1 , figure 2 , image 3 .

[0067] Taking the two-way six-lane as an example, the number of variable lanes and the determination method of the steering function of each lane after lane adjustment are as follows:

[0068] Step 1: Calculate the traffic capacity of the current two-way road, such as Figure 4 shown.

[0069] Step 2: Assuming that the number of variable lanes Δn=1, calc...

Abstract

The invention discloses a lane adjusting method for urban artery turning traffic. The method is used for relieving tidal flow in urban roads and mainly comprises the number of variable lanes in need of direction changing and a lane turning function determining method after lane adjustment. The method comprises that variable-direction traffic setting conditions of urban arteries are given, the number of variable lanes and the lane turning functions after lane adjustment are determined by combining control of tidal intersection signals, and intersection delay values are calculated and compared to obtain the lane adjusting method for urban artery turning traffic. According to the lane adjusting method, the intersection signal control and the variable-direction traffic technology are combined, so that the tidal traffic jam is relieved, the delay is reduced, and the utilization rate of existing road resources is improved effectively.

Description

technical field [0001] The invention belongs to the field of road traffic control, and in particular relates to a method for determining the variable number of lanes and the steering function of each lane after lane adjustment for urban arterial road change traffic. Background technique [0002] In recent years, with the adjustment of the space and functions of cities in our country, multi-centers, new cities, and urban areas (circles) have become new models of spatial expansion. More and more families live in new urban areas, work in urban centers, and travel daily. Relying on cars, the phenomenon of "job-housing separation" is quite common. Subsequently, the traffic flow on the connection channel between the new city and the central area presents obvious tidal characteristics: the morning (evening) peak often appears in the direction of entering (exiting) the city due to serious shortage of road resources, resulting in frequent congestion, while at the same time The pheno...
