Abstract

The embodiment of the invention discloses a traffic information quality evaluation method, a device and a system therefor, and relates to the communication field. In order to ensure the user to obtaina traffic information service with reliable quality, the technical scheme comprises the steps: acquiring road unit data of a specified area; acquiring track point data measured by a vehicle positioning device within the specified period of time; acquiring evaluation criterion data according to the acquired road unit data and the track point data; and evaluating the quality of the traffic information data provided by a traffic information service system according to the evaluation criterion data. The invention is applicable to process the traffic information.

Description

technical field [0001] The present invention relates to the communication field, in particular to a traffic information quality evaluation method, device and system. Background technique [0002] By obtaining real-time traffic information, estimating the time required for OD, inducing public travel routes, making full use of the space-time resources of the traffic system, and dispersing the utilization rate of main roads in the road network are one of the main methods to solve traffic congestion. ATIS (Advanced Traffic Information System, Advanced Traffic Information Service System) integrates mass information processing, data communication, electronic sensing and electronic control and other technical means into the entire traffic management and service, providing a wide range, comprehensive Real-time, accurate and efficient comprehensive traffic information service that plays a role in location. [0003] In actual situations, ATIS often releases real-time road traffic inf...
