Embodiment 1

[0040] 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 independently by the vehicle navigator or the server, or can be executed in cooperation with each other. The targets to be measured can be vehicles and pedestrians. etc., the method includes:

[0041] 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;

[0042] 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 si...

Embodiment 2

[0054] Embodiment 2 of the present invention is based on the above-mentioned technical solution, preferably, according to the road condition planning strategy, calculate the road condition change value of each road section to be tested according to the initial road condition value and the real-time road condition value, and calculate the road condition change value according to the road condition change value of each route to be tested Calculating the total traffic change value includes:

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

[0056] P = Σ i = 1 n ( P i - P i 0 )

[0057] Among them, n is the total number of sections of the road section ...

Embodiment 3

[0061] In Embodiment 3 of the present invention, it is preferable that the navigation server on the network side executes the operation of route planning, then after planning the optimal route between two points according to the destination and the current position, step 32 is also included: sending the optimal route to To mobile terminal equipment, such as mobile phones, PDAs, vehicle-mounted equipment, etc., such as figure 2 shown.

[0062] 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 a 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 a vehicle-mounted navigator, such as a vehicle-mounted navigation system. The navigator can be a mobile phone, and the optimal route can be sent to the mobile terminal in the form of text information.

[0063] There are ma...

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] 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...
