Embodiment Construction

[0054] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0055] Calculate the non-uniform coefficient of the traffic volume direction, and select the signal phase scheme according to the non-uniform coefficient of the traffic volume direction:

[0056] When the non-uniformity coefficient D of the traffic volume direction is not greater than 0.55, the conventional symmetrical phase clearance scheme is adopted at the intersection N, such as figure 1 ;

[0057] When the non-uniformity coefficient D of the traffic volume direction is within the range of (0.55, 0.60), the single-entry clearance scheme is adopted at the intersection N, such as figure 2 ;

[0058] When the non-uniformity coefficient D of the traffic volume direction is greater than 0.60, consider setting up short lanes with variable lanes.

[0059] The setting of variable short lanes also needs to meet the road conditions, including: th...

Abstract

The invention discloses a setting method for changing an urban road into a short lane, so as to relief the tide traffic phenomenon in urban roads. The setting method mainly comprises two aspects, namely setting condition and setting method. The method specifically comprises the steps as follows: firstly, providing the most rational signal control scheme of an intersection according to different degrees of the unbalance traffic, achieving balance between the traffic supplements and requirements by means of regulating time resource; when the phenomenon of unbalance is too serious to relieve by regulating time resource, considering to regulate from the aspect of space redistribution of existing road resource, taking the intersection and an upstream road section connected with the intersection as the objects, proposing a method of changing a lane into a short lane at the upstream road section connected with the intersection, and giving more road resources to the direction of high traffic flow through changing the directions of partial lanes according to the difference of bidirectional traffic flow, so as to rationally match the traffic supplements and requirements. The road can be re-divided through putting changeable isolation constructions in specific implementation.

Description

technical field [0001] The invention belongs to the field of road traffic control, in particular to a method for setting variable short lanes on urban roads. Background technique [0002] With the adjustment of space and functions of cities in our country, the phenomenon of "job-housing separation" is quite common, and residents rely more on cars to travel, resulting in a sharp increase in the number of motor vehicles. Subsequently, there are obvious tidal characteristics on the urban arterial road connecting the new city and the central area: morning (evening) peaks often appear 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 opposite direction road resources are not fully utilized. At present, as many as 20% to 40% of the roads and intersections in large and medium-sized cities are distributed in a "tidal" manner. The reason for this phenomenon is that the static traff...
