Embodiment Construction
[0048] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments.
[0049] Such as figure 1 As shown, the urban road traffic congestion evaluation method described in the present embodiment comprises the following steps:
[0050] S01. Select the target road section, divide a plurality of standard subsections, and calculate or obtain the corresponding road condition level indicators of these standard subsections from a third-party data source;
[0051] S02. Based on the road condition grade index of the continuous standard segment, set the congestion threshold, and use the congestion source calculation algorithm to ...

A method, system, and storage medium for evaluating the degree of urban road traffic congestion of the present invention include: selecting a target road section, dividing a plurality of standard subsections, and calculating corresponding road condition level indicators of these standard subsections; based on the road condition level indicators of continuous standard subsections, setting Determine the congestion threshold, use the congestion source calculation algorithm to find the congestion source; calculate the traffic damping coefficient of the congestion source according to the traffic level index of the congestion section; calculate the average Obstruction value: After accumulating historical data for a certain period of time, calculate the historical maximum average obstruction value of the road section, and calculate the obstruction index. The present invention can record in real time the amount of resistance to the traffic section caused by the discontinuous state caused by the source of congestion in the road section where the congestion occurs, and can intuitively reflect the degree of congestion on the road, and the process of the congestion spreading, spreading and disappearing over time. The establishment of control strategies provides a basis for decision-making.
Description
technical field [0001] The invention relates to the technical field of urban traffic management, in particular to a method, system and storage medium for evaluating the degree of urban road traffic congestion. Background technique [0002] In the current urban traffic congestion evaluation system, the congestion index or congestion coefficient is generally used as the evaluation index of traffic operation status, which can directly reflect the actual congestion status of the road, but in the same level, the evaluation of the degree of traffic congestion cannot be reflected. of. Contents of the invention [0003] The method and system for evaluating the degree of urban road traffic congestion proposed by the present invention can intuitively reflect the degree of road congestion and the process of the spread, spread and disappearance of congestion over time, and provide decision-making basis for the formulation of congestion control strategies. [0004] To achieve the abov...
