Abstract

The invention discloses a description method and a device for a traffic state. The method comprises the steps of receiving a traffic state inquiry request of a client, acquiring a line unit corresponding to the traffic state inquiry request, judging whether to describe the whole traffic state of the line unit according to a traffic state of a traffic state of a road section corresponding to directed road section sequence, generating a whole traffic state description for the line unit if so, generating a detailed traffic state description for the line unit is not, integrating the acquired whole traffic state description and / or the detailed traffic state description of the line unit to obtain a comprehensive traffic state description, and returning the comprehensive traffic state description to the client. The method and the device can provide more comprehensive and more traffic information for a user, and ensure that the user can learn the traffic states of the line units wholly and in detail and makes a travel plan.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method and device for describing traffic states. Background technique [0002] With the progress of urbanization in our country, the traffic environment has become increasingly severe due to the rapid increase of vehicles. Therefore, users need the assistance of the service system to understand dynamic traffic information, thereby saving users' travel time, relieving traffic pressure, and reducing traffic congestion. and delays. [0003] Due to the continuous improvement of the real-time traffic information collection and release system, the accuracy and coverage of dynamic traffic information are getting higher and higher, and the application of traffic information services has gradually entered people's daily life. [0004] In my country, there are not only traffic information release platforms based on VICS (Road Traffic Information and Communication System) ...
