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

Embodiment approach

[0040] This embodiment provides an implementation manner of step 102, including the following steps:

[0041] Step 1021, obtaining each road segment on the non-real-time traffic route starting from the current estimated position within the specified travel time;

[0042] Wherein, the designated travel time may be 3 minutes, 5 minutes or 10 minutes, etc., and may be adaptively adjusted according to actual road condition information. If the traffic condition information is relatively smooth, the specified travel time can be set larger, otherwise, the specified travel time can be set smaller. By setting the specified travel time and judging whether to re-plan according to the information of each road section within the specified travel time, the accuracy of the judgment result can be improved and the planning can be made more reasonable.

[0043] Specifically, when the real-time traffic route planning device obtains the non-real-time traffic route, it also estimates the time spe...

Abstract

The invention provides a planning method and a device of real-time road conditions and routes. The method comprises the following steps: according to the current position of the real-time road condition and route of a user, acquiring the current estimated position of an unreal-time road condition and route of the user, wherein, the unreal-time road condition and route is different from the real-time road condition and route and is an optimal route from a starting position to a destination of the user; judging whether the sum of weighted changing values of the road conditions of each roads in specified journey time from the current estimated position of the unreal-time road condition and route is larger than a preset threshold or not, if yes, carrying out planning on the real-time road condition and route from the current position to the destination to obtain the data of optimal real-time road condition and route. According to the invention, the planning volume of the route planning device can be reduced, unnecessary planning is avoided, the route planning efficiency of ITS is improved, and the burden of ITS is reduced.

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 According to the road condition information, the user's driving route is ...
