Embodiment Construction

[0035] A method for identifying congestion groups, the method includes the following steps.

[0036] 1. Delineate sampling area I at the upstream entrance of the road section, and delineate sampling area II at the downstream exit of the road section.

[0037] Sampling areas I and II can be delineated by one or a combination of the following methods:

[0038] 1.1) Delineated based on experience;

[0039] 1.2) Set a certain ratio according to the length of the road section for delineation;

[0040] 1.3) Delineate according to normal queuing area and super long queuing area.

[0041] In one embodiment, according to the driving direction, the vehicle travels from the upstream entrance of the road section to the downstream exit of the road section. Sampling area I is the area adjacent to the intersection at the upstream of the road section, sampling area II is the super-long queuing area, and the super-long queuing area is the area adjacent to the normal queuing area. The normal...

Abstract

The invention provides a congestion group identification method and system. Traffic parameter dual sampling is carried out on sampling areas at the two ends of a road section; a time difference duringtraffic congestion of the sampling areas at the two ends is obtained; on the basis of traffic parameters and the time difference, congestion relevance of intersections at the two ends of each road section is established; and the road section with strong congestion relevance and an intersection set form a congestion group. The identification of an influence range of the congested intersections iseffectively improved, so that the intersection signal control can be carried out in a targeted manner.

Description

technical field [0001] The invention relates to the problem of identifying traffic congestion, in particular to a method and system for identifying congestion groups. Background technique [0002] Urban road network is a huge and complex system, including the process of mutual evolution between traffic demand and traffic supply. Before formulating the traffic control strategy, if the traffic conditions on the road network and its temporal and spatial evolution cannot be accurately judged, the control effect of the formulated strategy may deviate far from the expected effect, or even have a negative effect, resulting in traffic congestion. further deterioration of the situation. [0003] In view of this problem, in the field of traffic control, it is increasingly necessary to consider both time and space factors in the process of solving the problem, to grasp the spatiotemporal law of the evolution of traffic conditions on the road network, to identify the evolution characte...
