Problems solved by technology

[0007] On the basis of absorbing the previous research results, the present invention aims at the defects of the traditional "overpass level" traffic organization form, and designs a new "overpass level" signal control intersection traffic organization design scheme, and proposes a single The traffic organization design scheme of the circular cross signal control intersection and the traffic organization design scheme of the double circular traffic signal control intersection, combining the double circular traffic signal control intersections to form a new grid-shaped urban road network traffic organization design scheme , and aiming at

Embodiment Construction

[0025] For the convenience of description, the above-mentioned design schemes will be explained in detail below in conjunction with the accompanying drawings.

[0026] The traffic organization design scheme of the new type "overpass level" signal control intersection:

[0027] The technical solution is as figure 2 As shown, it changes the two-way driving ramp of the traditional "interchange leveling" traffic organization form into a one-way ramp. All left-turning vehicles and right-turning vehicles must turn right at the main intersection before the on-ramp entrance to enter the ramp. Signal lights are set up at the entrance and exit for control, forming four secondary intersections and one main intersection. Vehicles turning right at the entrance of the ramp adopt yield control or signal control according to the size of pedestrian flow, and vehicles at the exit of the ramp use the main road Turn left, go straight and turn right at the red light time, the signal control phas...

Abstract

The invention discloses a traffic organization design and control improvement method of intersection passing capacity and road net traffic content in the traffic design and control domain, which is characterized by the following: adapting main road junction peripherial road net to form a micro-circulation system to finish steering task of each direction; adapting the ways such as í‹stop turning left or rightíŒ, í‹one way runningíŒ and so on to simplify the traffic intersection collision to improve the traffic intersection passing capacity; utilizing í‹green waveíŒ to reduce the parking frequency and driving delay. The program is fit for mutual matching of different grades, which realizes the city traffic harmonious development.

Description

technical field [0001] The invention relates to a traffic design and traffic control method for improving the traffic capacity of urban road networks and intersection capacity, and belongs to the field of traffic design and traffic control. [0002] The present invention is organized and discussed according to the traffic rules that vehicles drive on the right. When using the technical solution in countries or regions where vehicles drive on the left, it is only necessary to change "right" to "left" and "left" to "right". "That's it. Background technique [0003] Before discussing improving the traffic capacity of grid-shaped urban road network, we start with improving the traffic capacity of intersections. Most of the bottlenecks in urban road traffic are concentrated at intersections, which are the throats of urban road traffic and are the main factor causing traffic delays. According to statistics, in the urban road network, the time delayed by vehicles at intersections...
