Embodiment 1

[0024] This embodiment will combine the schematic figure 1 Provides a way to evaluate traffic information such as figure 2 As shown, the method includes:

[0025] In step 101, the test road segment is tested by a road test track device to obtain sample track data of the test road segment.

[0026] Specifically, when the test vehicle enters the planned test road section, the road test track device is turned on. The drive test track device takes the test vehicle as the target and records the track points of the test vehicle at each moment when it is driving on the test road section. Each track point has a The track point data with the track point is: sample track data, which includes information such as the speed of the vehicle to be tested at a certain position at a certain time, so as to collect and obtain the speed of the test vehicle at a certain spatial position at a certain time on the field. For example: at 8:02, at the position of coordinates (X1, Y1), the vehicle spe...

Embodiment 2

[0064] This embodiment provides a device for evaluating traffic information, such as Image 6 As shown, the device includes: a sample trajectory acquisition unit 61 , a standard answer processing unit 62 , and an evaluation unit 63 .

[0065] The sample trajectory acquisition unit 61 is used to test the test road section by the road test trajectory equipment so as to obtain the sample trajectory data of the test road section; the standard answer processing unit 62 is used to process the sample trajectory data according to the road test standard calculation method processing to obtain the standard answer road condition information; the evaluation unit 63 is used to evaluate the accuracy of the traffic system according to the real-time dynamic traffic flow information according to the standard answer road condition information.

[0066] Wherein, the standard answer processing unit 62 includes: a standard calculation module 621 and a standard answer acquisition module 622 .

Abstract

The embodiment of the invention discloses method and device for evaluating traffic information, which relates to the field of traffic information application and solves the technical problem of poorer reliability of the traffic information referenced by a user in the prior art. The method of the embodiment of the invention mainly comprises the following steps of: testing a tested road section through road testing track equipment to obtain sample track data of the tested road section; processing the sample track data according to a road testing standard computing mode to obtain standard answer road condition information; and according to the standard answer road condition information, evaluating the accuracy of the road condition information obtained by a traffic system according to real-time dynamic traffic flow information. The embodiment of the invention is mainly applied to evaluating the traffic information and providing traffic information service.

Description

technical field [0001] The invention relates to the application field of traffic information, in particular to a method and device for evaluating traffic information. Background technique [0002] At present, people's living standards are constantly improving and road traffic is constantly expanding. However, due to the rapid growth of vehicles and traffic, traffic contradictions are also very prominent. In order to ensure the passing time, people pay more and more attention to road conditions. Therefore, the operation of the intelligent transportation system was born. The intelligent transportation system can point out whether the current road conditions are congested or not, and the traffic information, etc. for users based on the detected real-time dynamic traffic flow information. [0003] However, with the growth of traffic demand, the reliability of road condition information obtained according to real-time dynamic traffic flow information is also particularly importan...
