Embodiment 1

[0025] Embodiments of the present invention provide a method for detecting traffic events, such as figure 1 As shown, the method includes:

[0026] 101. Obtain the GPS (Global Position System, Global Positioning System) information of the road link to be tested and the floating vehicle on the road link adjacent to the road link to be tested, and the road link adjacent to the road link to be tested includes the The preceding link and the succeeding link of the measuring link, the GPS information includes the speed information of the floating car.

[0027] Wherein, the preceding road link and the succeeding road chain of the road chain to be tested are two road chains connected with the road chain to be tested, and the road chain to be tested can extend to the successor road chain along the driving direction of the vehicle, and inversely The driving direction of the vehicle can be extended to the previous link. Since the vehicle travels in two directions on the same road link,...

Embodiment 2

[0034] The embodiment of the present invention also provides a method for detecting traffic events, such as figure 2 As shown, the method includes:

[0035] 201. Acquire GPS information of a floating car on a road link to be tested and a road link adjacent to the road link to be tested, wherein the GPS information of the floating car includes speed information of the floating car.

[0036] 202. According to the speed information of the floating car, generate speed values ​​of the link to be tested and links adjacent to the link to be tested.

[0037] Wherein, the expression method of the speed value may use the same expression method as that in the step 102 .

[0038] 203. Determine whether there is a traffic incident on the road link to be tested at the first time stamp, and the first time stamp is the previous time stamp of the current time stamp; if it is determined that the road link to be tested has no traffic incident at the first time stamp If a traffic event occurs,...

Embodiment 3

[0060] Embodiments of the present invention provide a method for detecting traffic events, such as image 3 As shown, the method includes:

[0061] 301. Acquire GPS information of a road link to be tested and a floating car on a road link adjacent to the road link to be tested, wherein the GPS information of the floating car includes speed information of the floating car.

[0062] 302. Generate speed values ​​of the link to be tested and links adjacent to the link to be tested according to the speed information of the floating vehicle.

[0063] Wherein, the expression method of the speed value may use the same expression method as that in the step 202 .

[0064] 303. Determine whether a traffic event occurs on the link to be tested at a third time stamp, where the third time stamp is a time stamp preceding the current time stamp. If it is determined that no traffic event occurs on the road link to be tested at the third time stamp, go to step 304 ; otherwise go to step 311 ....

Abstract

The invention discloses a method and a device for detecting traffic incidents and relates to the field of processing of traffic information, and the method and the device can be used for lowering the traffic incident detection cost. The method comprises the following steps: obtaining the global positioning system (GPS) information of a link to be tested and a floating car on a link adjacent to the link to be tested, wherein the link adjacent to the link to be tested comprises a front relay link and a rear relay link of the link to be tested, and the GPS information comprises the speed information of the floating car; according to the speed information of the floating car, generating the speed values of the link to be tested and the link adjacent to the link to be tested; and according to the speed values of the link to be tested and the link adjacent to the link to be tested, analyzing and determining the current traffic situation of the link to be tested. The embodiment of the invention is mainly used for detecting the traffic incident process.

Description

technical field [0001] The invention relates to the field of traffic information processing, in particular to a method and device for detecting traffic events. Background technique [0002] Increasing urban traffic congestion, frequent accidents, environmental degradation and energy shortages caused by traffic have become common challenges faced by countries all over the world. Traffic problems have become an important issue that governments of all countries need to solve. Among them, the frequent occurrence of urban road accidents is closely related to people's life safety and self-interest, and is related to the economic development and long-term stability of the society. It has gradually become a key issue of concern to the city's government and people. Paying closer attention to the application. [0003] Traffic incident detection is to use computer and information technology to act on the existing traffic information service system to timely, quickly and accurately loc...
