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 ...

The invention discloses an urban road traffic jam degree evaluation method and a system and a storage medium, and the method comprises the steps: selecting a target road section, dividing the target road section into a plurality of standard segments, and calculating the corresponding road condition grade indexes of the standard segments; based on the road condition grade indexes of the continuousstandard small segments, setting a traffic jam threshold value, and searching a traffic jam source by utilizing a traffic jam source calculation algorithm; calculating a traffic jam damping coefficient of the traffic jam source according to the road condition grade index of the traffic jam section; based on the traffic jam damping coefficient calculated in real time, calculating an average blocking value of the road section in the time period; and after accumulating historical data for a certain time, calculating a historical maximum average blocking value of the road section, and calculatinga blocking index. According to the invention, the resistance to the traffic section caused by the discontinuous state due to the traffic jam source in the road section due to traffic jam can be recorded in real time, the traffic jam degree of the road and the process of spreading, diffusing and disappearing the traffic jam along with the time change can be visually reflected, and a decision basisis provided for the formulation of a traffic jam control strategy.
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...
