Embodiment 1

[0040] figure 1 This is a flowchart of a route planning method based on real-time road conditions provided in the first embodiment of the present invention. figure 1 The first embodiment is described in detail. The first embodiment of the present invention provides a route planning method based on real-time road conditions. The method in this embodiment can be independently executed by a car navigation system or a server, or both can be executed in cooperation with each other. The target to be measured can be a vehicle or a pedestrian Etc. The method includes:

[0041] Step 10. Wait until the initial time of the next route planning judgment cycle to obtain the current position of the target to be measured;

[0042] Wait until the initial moment of the next route planning decision cycle. If the car navigator completes this method, the cycle is a fixed value, such as once every 10 minutes; if the server is completed, the cycle is triggered by waiting for a signal from the mobile term...

Embodiment 2

[0054] The second embodiment of the present invention is based on the above technical solutions. Preferably, according to the road condition planning strategy, the road condition change value of each road section to be tested is calculated according to the initial road condition value and the real-time road condition value, and the road condition change value of each road to be tested is calculated Calculating the total road condition change value includes:

[0055] Calculate the total road condition change value P according to the following formula;

[0056] P = X i = 1 n ( P i - P i 0 )

[0057] Among them, n is the total number of sections to be tested, i is the section number of the test section, P i Is the real-time road condition value of section i, P i0 Is the initial road condition value of the i-th section, P i -P i0 Is the road condition change value of the i-th route to be tested.

[0058] In practical applications, the set trav...

Embodiment 3

[0061] In the third embodiment of the present invention, it is preferable that the navigation server on the network side performs the route planning operation. After the optimal route between the two points is planned according to the destination and the current position, the method further includes step 32: sending the optimal route To mobile terminal equipment, such as mobile phones, PDAs, vehicle equipment, etc., such as figure 2 Shown.

[0062] In actual use, the route planning method based on real-time road conditions provided in the third embodiment of the present invention is preferably completed by a navigation server. The navigation server has a fast calculation speed, which can improve the efficiency of real-time navigation, and can greatly simplify the equipment of a car navigation system, such as a car The navigator can be a mobile phone, and the optimal route can be sent to the mobile terminal as a text message.

[0063] There are many ways to determine the position o...

Abstract

The invention discloses a route planning method and service equipment based on a real-time road condition. The method comprises the following steps of: acquiring the current position of a target to be measured at the initial time of the next route planning judgment period; acquiring the optimal determined route; acquiring a current initial road condition value of each road section; determining a road section within a set travel range in the optimal route as a road section to be measured; after setting an acquisition period, acquiring a real-time road condition value of each road section to bemeasured; calculating a total road condition changed value according to a road condition planning strategy; and judging whether the total road condition changed value is less than a preset value, if so, returning to the operation of acquiring the current position of the target to be measured without replanning the optimal route, otherwise, replanning the optimal route between two points accordingto the current position and a destination and returning to the operation of acquiring the current position of the target to be measured. By utilizing the route planning method and service equipment based on the real-time road condition provided by the invention, unnecessary navigation planning can be reduced.

Description

Technical field [0001] The embodiment of the present invention relates 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 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. to the transportation industry to form an information, intelligent, and social A new type of transportation system that enables transportation infrastructure to maximize its effectiveness. 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 navigatio...
