Problems solved by technology

The currently known traffic information quality monitoring and evaluation schemes are realized by on-site sampling testing of dynamic traffic information terminal products; the above-mentioned traffic information quality monitoring scheme requires sampling testing of dynamic traffic information terminal products, making the sample coverage density low, and the single evaluation time is as long as several days, which cannot reflect the current traffic information in a timely and accurate manner, resulting in poor accuracy of traffic information quality; and, because the above-mentioned scheme for traffic information quality monitoring requires on-site sampling testing of terminal products, makes testing costly

Embodiment 1

[0028] This embodiment provides a traffic information quality monitoring method, such as figure 1 As shown, the method includes:

[0029] 101. Obtain the information file containing the statistical information of the traffic road condition quality in real time.

[0030] It should be noted that the dynamic traffic information data processing flow is described as follows: collect GPS (Global Position System, Global Positioning System) track point data during taxi operation and road condition information data observed by video cameras, based on the map link (road link) ) as a unit to match the road condition data to each link of the electronic map to form GPS and video Tjam road condition data respectively; use the event information source to verify the road condition information and then integrate the GPS and video traffic condition data according to certain rules, Generate new Tjam traffic data, and generate RTICjam traffic data and TMCjam traffic data through link matching co...

Embodiment 2

[0050] This embodiment provides a traffic information quality monitoring device, such as image 3 As shown, the device includes: a first acquisition unit 21 , an analysis unit 22 , a first calculation unit 23 , a first comparison unit 24 , and a first output unit 25 .

[0051] The first acquiring unit 21 is configured to acquire information files including statistical information of traffic road condition quality in real time.

[0052] The analyzing unit 22 is configured to analyze the information file acquired by the first acquiring unit 21 to obtain the statistical information of the traffic road condition quality.

[0053] The first calculation unit 23 is used to calculate the travel time information coverage according to the traffic road condition quality statistical information obtained by the analysis unit 22; wherein, the first calculation unit 23 is based on the analysis unit 22. When the obtained traffic road condition quality statistical information is calculated to...

Abstract

The embodiment of the invention discloses a traffic information quality monitoring method and device, which relate to the field of traffic information processing, improve the accuracy of real-time traffic information quality monitoring, and reduce the cost of real-time traffic information quality evaluation and testing. The method includes: acquiring information files containing statistical information of traffic road condition quality in real time; analyzing the information file to obtain the statistical information of traffic road condition quality; calculating the travel time information coverage according to the statistical information of traffic road condition quality rate; compare the travel time information coverage with the monitoring standard travel time information coverage; if the travel time information coverage is lower than the monitoring standard travel time information coverage, the travel time information coverage Output of comparison with monitoring standard travel time information coverage. The invention is suitable for the online monitoring process of traffic information processing process data.

Description

technical field [0001] The invention relates to the technical field of traffic information processing, in particular to a traffic information quality monitoring method and device. Background technique [0002] Dynamic traffic information service has always been a hot research issue in the field of intelligent transportation. At present, the evaluation norms and standards of traffic information products have been issued. A quality monitoring and evaluation program for dynamic traffic information terminal products has been proposed and implemented. The currently known traffic information quality monitoring and evaluation schemes are realized by on-site sampling testing of dynamic traffic information terminal products; the above-mentioned traffic information quality monitoring scheme requires sampling testing of dynamic traffic information terminal products, making the sample coverage density low, and the single evaluation time is as long as several days, which cannot reflect ...
