Example Embodiment
[0053] Example one
[0054] The traffic incident recognition method of the embodiment of the present invention is applied to RSU, such as figure 1 As shown, including the following steps:
[0055] Step 101: Receive traffic flow information collected by each sensor coil laid on the road to be predicted;
[0056] Step 102: Use current traffic flow information and historical traffic flow information to determine 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 total time that the sensor coils on the road to be predicted are occupied by vehicles and the observed duration.
[0059] Wherein, the traffic volume refers to the number of vehicles passing through the sensor coil in a unit time. The unit is vehicles / h.
[0060] The average speed of traffic flow refe...
Example Embodiment
[0095] Example two
[0096] On the basis of Embodiment 1, this embodiment describes the process of traffic incident recognition in detail.
[0097] image 3 It is a schematic diagram of the system architecture of an embodiment of the present invention. From image 3 It can be seen that the solution of the embodiment of the present invention is: the sensor coil collects vehicle motion data, and transmits the collected data (traffic flow information) to the RSU. 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 cloud platform analyzes the collected data for a period of time, analyzes the relevant information of the traffic incident, and sends the traffic incident classification result and the traffic incident location information to the RSU through the base station, and the RSU broadcasts the information to Vehicles, reminding vehicles to avoid the location of the traffic incident...
Example Embodiment
[0146] Example three
[0147] To implement the method in the embodiment of the present invention, this embodiment provides a traffic incident recognition device, which is set in the RSU, such as Picture 9 As shown, the device includes:
[0148] The first receiving unit 91 is configured to receive traffic flow information collected by each sensor coil laid on the road to be predicted;
[0149] The determining unit 92 is configured to use current traffic flow information and historical traffic flow information to determine the traffic parameters of the road to be predicted;
[0150] The first sending unit 93 is configured to send the determined traffic parameter to the platform; the determined traffic parameter is used for traffic incident recognition.
[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 total time that the sensor coils on the road to be predicted are occupied b...
