Embodiment 1
[0029] figure 1 It is a flow chart of an embodiment of a method for evaluating the degree of road congestion according to an exemplary embodiment of the present invention. The method for evaluating the degree of road congestion can be applied to a computer device, which can be a terminal, a PC, a server, etc. . Such as figure 1 As shown, the road congestion evaluation method includes the following steps:
[0030] Step 101: Obtain the value of at least one congestion evaluation index for each target road segment.
[0031] In this embodiment, the type of the target road section may include a static road section and a dynamic road section. The static road section refers to a road section whose starting position and end position are fixed, and the dynamic road section refers to a road section whose starting position and end position are uncertain. A road segment that changes as it changes, so a dynamic road segment can be composed of at least one sub-segment.
[0032] In an ex...
Embodiment 2
[0062] On the basis of the above-mentioned embodiment 1, the evaluation process of the congestion degree of the road section is introduced below by taking the static road section with the fixed starting position and the ending position as an example:
[0063] (1) Calculate the value of the congestion evaluation index of the static road section.
[0064] For static road sections, commonly used congestion evaluation indicators include average congestion duration, variance of congestion duration, average congestion length, variance of congestion length, etc.
[0065] use Indicates the congestion duration of the static road section i on day d, and D represents the number of days participating in the analysis, then the average congestion duration of the static road section i Calculated as follows:
[0066]
[0067] Congestion duration variance of static section i Calculated as follows:
[0068]
[0069] use Indicates the congestion length of the static road segment i...

Abstract
The invention discloses a road section congestion degree evaluation method and device. The method comprises the steps of obtaining a numerical value of at least one congestion evaluation index of each target road section; determining a weight coefficient of each congestion evaluation index by utilizing the numerical value of each congestion evaluation index under each target road section; and for each target road section, determining a comprehensive evaluation value of the target road section by using the numerical value of each congestion evaluation index under the target road section and the weight coefficient of each congestion evaluation index, wherein the comprehensive evaluation value is positively correlated with the congestion degree. By utilizing the numerical value of each congestion evaluation index under each target road section, the weight coefficient of the congestion evaluation index is calculated in a scientific and reasonable manner to reflect the importance degree of the congestion evaluation index, so that subjective judgment introduced by a decision maker due to lack of quantitative indexes is avoided, therefore, the congestion degree of the target road section is obtained through evaluation according to the weight coefficient of the congestion evaluation index and the numerical value of the congestion evaluation index under the target road section, and the reliability and authority are higher.
Description
technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method, device, equipment, and storage medium for evaluating road congestion degree. Background technique [0002] With the increasing number of cars, road congestion has become a difficult problem faced by many cities. In order to alleviate traffic congestion, traffic management departments need to accurately locate congested road sections. However, limited by manpower and material resources, the traffic management department cannot deal with all congested road sections at the same time, and needs to give priority to solving the most congested roads according to the degree of road congestion. Therefore, it is a technical problem that needs to be solved to provide accurate and reasonable evaluation results of congested road sections for the traffic management department. Contents of the invention [0003] The object of the present invention is to propose ...
