Problems solved by technology

However, due to the large and increasing number of driving users, if the ITS route planning is unreasonable, it will not only fail to respond to the user's navigation request in time, the planning efficiency will be low, and it will also increase the burden on the ITS. Therefore, how to make a reasonable route Planning becomes a big issue for ITS

Abstract

The invention provides a method and a device for planning a real-time road-condition route. The method comprises the following steps: acquiring a current estimated position of a user on a non-real-time road-condition route according to a current position of the user on a real-time road-condition route, wherein the non-real-time road-condition route is different from the real-time road-condition route and is the optimal route of the user from a starting point to a destination; judging if the summation of change values of road-conditions from the current estimated position to an appointed section of the destination on the non-real-time road-condition route is more than a preset threshold value; and if yes, planning the real-time road-condition route from the current position to the destination, so as to generate the optimal road-condition route information. The technical scheme in the invention can be used for reducing planning capacity of a route planning device, avoiding unnecessary planning, promoting route planning efficiency of an ITS (Intelligent Transportation System) and reducing ITS load.

Description

technical field [0001] The invention relates to intelligent transportation technology, in particular to a real-time road condition route planning method and equipment. Background technique [0002] Intelligent Transport System (Intelligent Transport System; referred to as: ITS), refers to the application of advanced information technology, data communication transmission technology, electronic control technology, computer processing technology, etc. , Socialized new transportation system, which enables the transportation infrastructure to maximize its effectiveness. Driving guidance for users traveling by car is one of the main functions of ITS. [0003] Since there are usually multiple driving routes between the starting point and the destination point of the user's trip, and the road conditions on each route are different and will change in real time, one of the tasks of ITS to guide the user is to The information plans the user's driving route in real time to provide th...
