Embodiment 1

[0026] An embodiment of the present invention provides a method for determining the release of a traffic event, such as figure 1 As shown, the method includes:

[0027] In step 101, the floating car data in the area where the road link where the traffic incident occurs is acquired.

[0028] The present invention can be realized by using a computer program. Specifically, in this embodiment, the computer can obtain the road link where the traffic event is located from the electronic map stored in the computer through the existing technical means, and obtain the traffic event through the server in the navigation system. The floating car data of the road link where the event is located, for example: in the navigation system, the server regularly records the floating car data on the specific road corresponding to each road link in the storage device (such as database, network hard disk, etc.), and the computer can pass the routine Information transmission or access means to obtain...

Embodiment 2

[0036] An embodiment of the present invention provides a method for determining the release of a traffic event, such as figure 2 As shown, the method includes:

[0037] In step 201, the floating car data in the area where the road link where the traffic incident occurs is acquired.

[0038] Step 202: Obtain the link speed of the link where the traffic event occurred and the link speeds of two adjacent links to the link where the traffic event occurred at the current time according to the data of the floating car.

[0039] Wherein, the link speed is the traffic flow speed on the road corresponding to the link.

[0040] For example: in the computer, the road links in the area can be expressed in the form of a set: L={l|l=(l-1, l, l+1)} is a continuous uninterrupted set of directed road links, where , l represents the road link where the traffic incident occurred, specifically the ID number of the road link where the traffic incident occurred in the electronic map, and the com...

Embodiment 3

[0071] An embodiment of the present invention provides a device for judging the release of a traffic event, such as image 3 As shown, the device includes:

[0072] The floating car data acquisition module 31 is used to acquire the floating car data in the area where the road link where the traffic incident occurs.

[0073] The link speed acquisition module 32 is configured to acquire the link speed according to the floating car data.

[0074] Wherein, the link speed is the traffic flow speed on the road corresponding to the link.

[0075] A judging module 33, configured to judge whether the traffic event is resolved according to the link speed.

[0076] The device for determining the release of a traffic event provided by the embodiment of the present invention can obtain the link speed of the link where the traffic event is located through the link speed acquisition module according to the floating car data, and determine whether the traffic event can be canceled according...

Abstract

The embodiment of the invention discloses a method and device for judging release of a traffic incident, relating to the field of intelligent traffic systems. Whether the traffic incident is released is automatically judged according to a quantized specific value obtained according to floating car data, and subjective deviation caused in a manual judgment process is avoided, thus the accuracy of judging the release of the traffic incident is improved. The method provided by the invention comprises the steps of: obtaining the floating car data in an area where a road link generating the traffic incident occurs; obtaining a speed of the road link according to the floating car data, wherein the speed of the road link is a traffic flow speed on a road corresponding to the road link; and judging wherein the traffic incident is released or not according to the speed of the road link. The invention is suitable for judging the release of the traffic incident.

Description

technical field [0001] The present invention relates to the field of intelligent traffic systems, in particular to a method and device for judging the release of traffic events. Background technique [0002] With the acceleration of the urbanization process, the urban traffic situation is becoming more and more severe, and the number of various traffic accidents and traffic incidents is increasing. For the existing traffic information service system, the ability to eliminate traffic incidents and restore the road to normal traffic It directly affects the operating efficiency of the traffic information service system. [0003] In order to enable the traffic information service system to determine in time whether the traffic incident can be resolved, the prior art provides the following methods: [0004] In the traffic information center of the traffic information service system, a set of judging standards for canceling events corresponding to various traffic events is formul...
