Embodiment 1

[0039] figure 1 The flow chart of the route planning method based on real-time road conditions provided by Embodiment 1 of the present invention is combined below figure 1 Embodiment 1 will be described in detail. Embodiment 1 of the present invention provides a route planning method based on real-time road conditions. The method of this embodiment can be executed by a vehicle navigator or a server, or by the cooperation of the two. The targets to be measured can be vehicles, pedestrians, etc. , the method includes:

[0040] Step 10. Waiting until the initial moment of the next route planning determination period, and obtaining the current position of the target to be measured;

[0041] Wait until the initial moment of the next route planning decision period. If this method is completed for the car navigator, the period is a fixed value, such as once every 10 minutes; if the server is completed, the period is triggered by waiting for a signal from the mobile terminal. Such ...

Embodiment 2

[0053] Embodiment 2 of the present invention is based on the above technical solution, preferably, according to the road condition planning strategy, calculate the weighted road condition change value of each road section to be tested according to the travel time, the initial road condition value and the real-time road condition value, through each The weighted road condition change value of the measured road section calculates the total weighted road condition change value including:

[0054] The total weighted road condition change value P is obtained according to the following formula:

[0055] P = Σ i = 1 n ΔP i × ( T - t i ) / T × V

[0056]...

Embodiment 3

[0074] The difference between this embodiment and Embodiment 1 is that after the optimal route between two points is planned according to the destination and the current location, step 32 is also included: sending the optimal route to a mobile terminal device, such as a mobile phone, PDA, car equipment, etc., such as figure 2 shown.

[0075] In actual use, the route planning method based on real-time road conditions provided by Embodiment 3 of the present invention is preferably completed by the navigation server. The navigation server has a fast calculation speed, can improve the efficiency of real-time navigation, and can greatly simplify the equipment of the vehicle navigation terminal, such as the vehicle navigation terminal. The navigation terminal can be a mobile phone, and the optimal route can be sent to the mobile terminal in the form of text information.

[0076] There are many ways to determine the position of the target to be measured, one of which is to install ...

Abstract

The invention discloses a real time road condition based route planning method and service equipment thereof. The method comprises steps of: waiting and acquiring a current position of an object to be measured; acquiring a determined optimal route; acquiring time travelling from the current position to terminal points in the optimal route and initial road condition values; determining roads to bemeasured; setting an acquisition period and acquiring real time road condition values of each roads to be measured; calculating total weighted road condition change values according to a road condition planning strategy; determining whether the total weighted road condition change values is less than a pre-determined value; if it is, considering no need to plan an optimal route again and returning to operate the operation of waiting a current position of an object to be measured; if it is not, planing the optimal route again according to the current position and a destination, and returning to operate the operation of waiting a current position of an object to be measured. The real time road condition based route planning method and service equipment thereof provided by the invention can reduce planning times of a navigation route.

Description

technical field [0001] Embodiments of the present invention relate to intelligent transportation technology, in particular to a route planning method based on real-time road conditions and service equipment thereof. Background technique [0002] Intelligent Transportation 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. A new, modernized transportation system that maximizes the performance of the transportation infrastructure. Real-time route planning is an important part of intelligent transportation system. [0003] Chinese patent CN201069361 discloses a navigation device that can provide traffic information. By receiving traffic information, it provides users with real-time and accurate traffic information. The navigation device can design or change existing routes according to traffic info...
