Problems solved by technology

[0003] However, the existing traffic incident detection is mainly based on video files, so multiple cameras need to be placed on the road, and each camera transmits video files to the platform, and then visually analyzes the video files to obtain traffic incidents. The cost of the method is high; and when extreme weather occurs, the identification efficiency of traffic events is low

Embodiment 1

[0054] The traffic event identification method of the embodiment of the present invention is applied to RSU, such as figure 1 shown, including the following steps:

[0055] Step 101: receiving traffic flow information collected by each sensing coil laid on the road to be predicted;

[0056]Step 102: Using current traffic flow information and historical traffic flow information, determine the traffic parameters of the road to be predicted;

[0057] Step 103: Send the determined traffic parameters to the platform.

[0058] Here, the traffic parameters may include traffic flow, average speed of traffic flow, and time occupancy rate; the time occupancy rate is the ratio of the sum of time that the sensor coils on the road to be predicted are occupied by vehicles to the observation time.

[0059] Wherein, the traffic volume refers to the number of vehicles passing the sensing coil per unit time. The unit is vehicle / h.

[0060] The average speed of the traffic flow refers to: th...

Embodiment 2

[0096] On the basis of the first embodiment, this embodiment describes the process of identifying traffic events in detail.

[0097] image 3 It is a schematic diagram of the system architecture of the embodiment of the present invention. From image 3 As can be seen from the figure, the solution of the embodiment of the present invention is: the sensor coil collects vehicle movement data, and transmits the collected data (traffic flow information) to the RSU, and the RSU calculates the traffic parameters of the road section, and sends the traffic parameters through the base station To the cloud platform, the cloud platform analyzes the collected data for a period of time, analyzes the relevant information of traffic incidents, and sends the classification results of traffic incidents and the location information of traffic incidents to the RSU through the base station, and the RSU broadcasts the information to Vehicles, reminding vehicles to avoid traffic incidents.

Embodiment 3

[0147] In order to realize the method of the embodiment of the present invention, this embodiment provides a traffic event identification device, which is set in the RSU, such as Figure 9 As shown, the device includes:

[0148] The first receiving unit 91 is configured to receive the traffic flow information collected by the sensing coils laid on the road to be predicted;

[0149] A determining unit 92, configured to determine the traffic parameters of the road to be predicted by using current traffic flow information and historical traffic flow information;

[0150] The first sending unit 93 is configured to send the determined traffic parameters to the platform; the determined traffic parameters are used for identifying traffic events.

[0151] Here, the traffic parameters may include traffic flow, average speed of traffic flow, and time occupancy rate; the time occupancy rate is the ratio of the sum of time that the sensor coils on the road to be predicted are occupied by...

Abstract

The invention discloses a traffic event identification method comprising the following steps: receiving traffic parameters (sent by a road test unit) of a to-be-predicted road, wherein the traffic parameters are obtained according to traffic flow information gathered by each sensing coil on the to-be-predicted road; using the traffic parameters and employing a hierarchy classification mode to classify the traffic parameters, thus obtaining a classification result; using the classification result to identify a traffic event on the to-be-predicted road. The invention also discloses a traffic event identification device.

Description

technical field [0001] The invention relates to the Internet of Things technology, in particular to a traffic event identification method and device. Background technique [0002] Traffic incidents refer to sporadic events on expressways that affect traffic safety and smooth flow, such as vehicle traffic accidents, breakdown parking, control, etc. Traffic incidents have a serious impact on road traffic. It has been reported that 60% of traffic congestion is caused by non-periodic congestion caused by traffic incidents, and it is increasing rapidly year by year. Therefore, the detection of traffic events and the prediction of traffic flow changes caused by traffic events have an important impact on the improvement of road traffic efficiency. [0003] However, the existing traffic incident detection is mainly based on video files, so multiple cameras need to be placed on the road, and each camera transmits video files to the platform, and then visually analyzes the video file...
