Embodiment 1

[0046] This embodiment provides a real-time release method for road congestion reasons, such as figure 1 shown, including the following steps:

[0047] S1: Continuously track each vehicle that enters the video tracking range.

[0048] S2: Respectively acquire the first speed of each vehicle at the first moment and the second speed at the second moment.

[0049] S3: Determine whether the first speed is equal to the second speed, if yes, go to step S4, otherwise go to step S5.

[0050] S4: Judging whether the difference between the first speed and the second speed is greater than or equal to the speed difference threshold, if yes, go to step S6, otherwise return to step S1. The speed difference threshold is flexibly selected according to the location of the road and the traffic flow at that time. For example, the speed difference threshold=(first speed−second speed)*0.5 can be selected.

[0051]S5: Judging whether the first speed and the second speed are both less than or eq...

Embodiment 2

[0069] This embodiment provides a real-time release system for road congestion reasons, such as image 3 shown, including:

[0070] Vehicle-mounted terminals, set up on vehicles that need to release the cause of congestion.

[0071] The speed acquisition unit is configured to acquire the first speed of each vehicle within the video tracking range at the first moment and the second speed at the second moment.

[0072] A first judging unit judging whether the first speed is equal to the second speed.

[0073] A second judging unit, when the first speed is not equal to the second speed, judging whether the difference between the first speed and the second speed is greater than or equal to a speed difference threshold. The speed difference threshold is flexibly selected according to the location of the road and the traffic flow at that time. For example, the speed difference threshold=(first speed−second speed)*0.5 can be selected.

[0074] A third judging unit, when the first...

Abstract

The invention discloses a method and system for releasing the reason for road congestion in real time. According to the method and system for releasing the reason for the road congestion in real time, a vehicle is tracked continuously through the video tracking technique so that the traffic condition of a current roadway can be obtained in real time, the whole road section within the video tracking range can be monitored through the video tracking technique, the condition of the whole road section can be reflected, and once the congestion appears, an image of the area where the congestion appears can be immediately sent to a vehicle-mounted terminal, and then a driver can learn the reason for the congestion appearing on the front roadway and the degree of the congestion according to image information. According to the method and system for releasing the reason for the road congestion in real time, the abnormal parking situation on the roadway can also be monitored accurately in real time, and once a vehicle is parked abnormally, an image of the area where the vehicle is parked abnormally is sent to the vehicle-mounted terminal no matter whether congestion is caused.

Description

technical field [0001] The invention relates to the field of intelligent traffic information release, in particular to a method and system for real-time release of road congestion reasons. Background technique [0002] With the rapid growth of urban traffic demand, road traffic is becoming increasingly busy. Traffic congestion due to heavy motor vehicle traffic, illegal activities, traffic accidents, vehicle breakdowns, icy roads and other reasons occurs from time to time. To this end, the traffic management department adopts various methods to collect, analyze, and process the information of the current traffic conditions, and releases the processing results to the traffic participants in three colors: red, yellow, and green. When the display board or vehicle-mounted terminal sees that the traffic condition of the road ahead is red, it can only indicate that the road ahead is seriously congested. To what extent, how long will it last, and what causes the congestion, traffi...
