Embodiment Construction

[0035] This part further clarifies the present invention in conjunction with example, should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention, after reading the present invention, those skilled in the art can modify various equivalent forms of the present invention All fall within the scope defined by the appended claims of this application.

[0036] A motor vehicle navigation method that integrates safety and travel time. The method first determines all alternative routes between the start point and the end point, and divides the route into n road sections; The safety index and weight of n sections of the route and calculate the safety c of each section; then, determine the travel distance s and travel time t of each section of each route, and calculate the total travel distance S of each route and travel time T; then, according to the safety c and travel distance s of each sec...

Abstract

The invention provides a motor vehicle navigation method integrating safety and travel time vehicle. With the method adopted, various indicators affecting the travel safety of motor vehicles are comprehensively considered, a relationship between travel safety and travel time is solved, and a motor vehicle navigation route enabling relatively optimal safety and travel time on the whole can be recommended. The method includes the following steps that: all alternative routes between a starting point and a terminal point are determined; the safety indicators and weights of n road segments constituting each route are determined according to certain safety evaluation standards, and the safety c of each road segment is calculated; the total travel distance S and travel time T of each route are obtained through calculation; average safety is calculated according to the safety c and travel distance s of each road segment of each route, and then, safety C' corresponding to travel time t is calculated, and the final safety of each route is obtained on the basis of the integration of the average safety and the safety corresponding to the travel time; and a route with the highest final safety scores is selected as an optimal motor vehicle travel route.

Description

technical field [0001] The invention relates to a method for determining the best travel route of a motor vehicle according to the safety and travel time of different alternative routes, and belongs to the technical field of navigation. Background technique [0002] The current navigation technology supports the shortest time, the shortest distance or the least charge. In recent years, people's safety awareness has gradually increased, and they are often more willing to choose a safer route for travel. In the existing navigation software, there has never been a navigation method with safety as the standard. The lack of this method may lead to similar travel time, and the system recommends less safe routes for users, which increases the probability of traffic accidents. Therefore, the present invention proposes a motor vehicle navigation method that integrates safety and travel time. Contents of the invention [0003] The present invention takes the motor vehicle navigati...
