Embodiment 1

[0046] This embodiment 1 provides a system for judging an interruption state of a road segment, and the system includes:

[0047] The acquisition module is used to acquire the historical traffic flow between the gantry pairs;

[0048] The calculation module is used to calculate the boundary threshold of the historical traffic flow under different characteristic conditions based on the historical traffic flow;

[0049] The judgment module is used to judge whether the real-time traffic flow between the gantry pair is equal to zero, if it is equal to zero, then judge whether the real-time traffic flow between the gantry pair is lower than the boundary threshold, if it is lower than the boundary threshold, then the gantry pair Road traffic is disrupted.

[0050] In this embodiment 1, the above-mentioned road segment interruption state judgment system is used to realize a road segment interruption state judgment method, which includes the following steps:

[0051] Get historical ...

Embodiment 2

[0065] This embodiment 2 provides a method for judging the interruption state of a road segment, such as figure 1 As shown, calculate the traffic flow between the gantry pairs based on the gantry data, and classify the data according to different characteristics, such as holiday characteristics, week characteristics, hour characteristics, etc., calculate the traffic flow between the gantry pairs under different characteristic conditions Calculate the real-time traffic flow between the gantry pair, determine whether the real-time traffic flow between the gantry pair is equal to zero, if so, further judge whether the real-time traffic flow between the gantry pair is lower than the boundary threshold, If so, it is judged that the road traffic between the pair of gantry is interrupted.

Embodiment 3

[0097] Embodiment 3 of the present invention provides an electronic device, including a memory and a processor, the processor and the memory communicate with each other, the memory stores program instructions that can be executed by the processor, and the processor invokes the A method for judging the interruption state of a road segment is executed according to the program instruction, and the method includes the following process steps:

[0098] Get historical traffic flow between gantry pairs;

[0099] Calculate the boundary thresholds of historical traffic flow under different characteristic conditions based on historical traffic flow;

[0100] Determine whether the real-time traffic flow between the gantry pair is equal to zero, if it is equal to zero, then judge whether the real-time traffic flow between the gantry pair is lower than the boundary threshold, if it is lower than the boundary threshold, the road traffic between the gantry pair is interrupted state.

Abstract

The invention provides a road section interruption state judgment method and system, and belongs to the technical field of traffic operation management, and the method comprises the steps: obtaining the historical traffic flow between portal pairs; calculating boundary thresholds of the historical traffic flow under different characteristic conditions based on the historical traffic flow; and judging whether the real-time traffic flow between the portal pairs is equal to zero or not, if so, judging whether the real-time traffic flow between the portal pairs is lower than a boundary threshold value or not, and if not, judging that the road traffic between the portal pairs is in an interrupted state. According to the invention, the problems of false report, missing report and untimely report of the sampling data are avoided; the problem that only the slow or congested state of the road section can be judged according to the designed speed of the highway, the average speed of the road section and the saturation is solved; according to the method, a traffic flow boundary condition calculation method is provided, interruption state judgment conditions are established, the situation that the road section between the gantries is mistakenly judged to be in an interruption state can be effectively avoided, and the accuracy of judgment of the interruption state of the road section is improved.

Description

technical field [0001] The invention relates to the technical field of traffic operation management, in particular to a method and system for judging the interruption state of a road section based on the full amount of gantry data. Background technique [0002] "Interim Technical Requirements for Highway Network Operation Monitoring and Service", "Technical Requirements for Expressway Network Operation Monitoring and Service", and "Research on Real-time Evaluation Parameters and System Implementation of Road Network Traffic Operation Situation" in "Traffic Technology and Management" No. 34 in 2021 The "interruption rate" index is introduced to describe the interruption of road sections in the road network, including three indicators: road section interruption status, road interruption status and road network interruption rate. [0003] The link disconnection state describes whether a link is connected or disconnected. The connected state refers to the state where the vehicl...
