Embodiment Construction

[0022] Embodiments of the present invention provide a traffic information evaluation method and device for measuring by vehicle-mounted positioning equipment and determining actual measurement data of a merged road section. The merged road section is a road section formed by merging at least two sequentially connected road units. The traffic information data is evaluated according to the measured data of each merged road segment. Due to the large number of signal lights in the main road and the secondary road, by merging road sections, each signal light has less influence on the measured data, thereby reducing the influence of signal lights on traffic information evaluation and improving the accuracy of traffic information evaluation.

[0023] Such as figure 1 As shown, the traffic information evaluation method provided by the embodiment of the present invention includes:

[0024] Step S101. Carry out vehicle positioning equipment measurement, and determine the actual measure...

Abstract

The invention discloses a traffic information evaluation method and a traffic information evaluation device, and relates to a traffic information technology. The traffic information evaluation method in the embodiment of the invention comprises the following steps of: performing vehicle-mounted positioning equipment measurement, and determining the measured data of merged road sections, wherein each merged road section is formed by merging at least two road units which are sequentially connected; and evaluating traffic information data according to the measured data of each merged road section. Each of main roads and secondary main roads has a great number of signal lamps, and the influence of each signal lamp on the measured data is reduced by the merged road sections, so that the influence of the signal lamps on traffic information evaluation is reduced, and traffic information evaluation accuracy is improved.

Description

technical field [0001] The invention relates to traffic information technology, in particular to a traffic information evaluation method and device. Background technique [0002] The traffic information service system is an important part of the intelligent transport system (Intelligent Transport System, ITS). Improving and improving the quality of traffic information service is an important way to alleviate urban traffic congestion and improve the level of traffic information service, and it is also an inevitable demand to promote the further rapid development of my country's intelligent transportation industry. [0003] In actual situations, the traffic information service system collects and processes traffic information, and releases real-time road traffic information (including road speed, road OD travel time, and road congestion status, etc.) through various information release methods. And ways are provided to users so that they can adjust the time, route, and way of...
