Problems solved by technology
[0003] Under the existing technical conditions, the evaluation of the degree of road congestion is either limited to a limited road section, or can only make an inaccurate evaluation of the entire route between two locations, which lacks sufficient guiding significance for travel
In addition, under the existing technical conditions, it is not possible to evaluate the road congestion degree of the road network in a geographical area, which is not conducive to understanding the traffic conditions of the road network in a geographical area

The invention belongs to the technical field of big data, and relates to a road congestion degree evaluation method, device, computer equipment and a storage medium. The method comprises steps: N selected road sections are determined in a road network database, wherein N is a positive integer; the maximum traffic flow Bi (i=1, i=2, i=3...i=N) of each selected road section in a preset time period is acquired from a traffic flow database; a traffic flow Ai (i=1, i=2, i=3...i=N) of each selected road section in an evaluation time period is acquired from the traffic flow database; a congestion index ei of each selected road section in the evaluation time period is calculated according to the acquired traffic flow Ai and the maximum traffic flow Bi; according to the acquired maximum traffic flow Bi, the weight wi of each selected road section contributing to the congestion of all the selected road sections is calculated; and in combination of the congestion index ei of each selected road section and the weight wi for contribution to the congestion of all the selected road sections, a congestion index E of all selected road sections is calculated. Thus, the congestion degree of the roadcan be accurately evaluated.
Description
technical field [0001] The application belongs to the technical field of big data, and relates to a method, a device, a computer device and a storage medium for evaluating the degree of road congestion. Background technique [0002] Road checkpoints refer to electronic devices distributed at road intersections for collecting vehicle information data. The electronic eye at the road crossing is a kind of said road checkpoint. The road checkpoint adopts photoelectric technology, image processing technology, pattern recognition technology, etc. to collect information data such as the image of each passing vehicle. The information data of vehicles collected at road checkpoints are stored in the traffic flow database. The number of vehicles passing a road section within a unit time can be obtained through the vehicle flow database. [0003] Under the existing technical conditions, the evaluation of road congestion is either limited to a limited road section, or can only make an...
