A Determination Method of Motor Vehicle Travel Route Based on Historical Data

Abstract

The invention relates to a motor vehicle travel route determination method based on historical data, which assumes that the travel time of a road section is mutually independent, and is in normal distribution, and the congestion probability is mutually independent, and particularly comprises the following steps that: step 1, setting the origin point and the destination point, resolving traffic network balance problem considering section capacity restrain to obtain a candidate route set and section congestion waiting time, for candidate routes, evaluating the steering delay at crossings, calibrating the difference of the expected value of the travel time of the road section and the standard, and taking the road section lower than 10km / h as a congestion road section to calculate the congestion probability of the road sections; step 2, respectively resolving the waiting time of the candidate routes, determining the travel time distribution of the candidate routes to obtain the alpha-position travel time of the candidate routes, and calculating the congestion probability of the candidate routes; and step 3, displaying the alpha-position travel time, the congestion probability and the waiting time of the candidate routes according to the small to large order of the alpha-position travel time of the candidate routes, and selecting the travel route by a user from the candidate routes.

Description

technical field [0001] The invention relates to a method for determining a travel route of a motor vehicle that only uses historical data and considers travel time reliability, waiting time and congestion probability. [0002] Background technique [0003] The route determination method is to select the best driving route for the user based on the starting and ending points set by the user and using the map and traffic information mastered. At present, the route determination methods in most vehicle navigation systems and geographic information websites only consider the level, geometry and topological characteristics of the road network itself, according to the user's preferences (such as choosing whether to use expressways, whether to prefer to drive on arterial roads) , choosing the geometrically shorter path. Although the intelligent transportation systems in most cities in China are still unable to determine the best driving route for users based on real-time dete...

Problems solved by technology

[0005] From the user's point of view, when the travel time of the route is not much different, the influence of the waiting time and the congestion probability of the route on the user's choice cannot be ignored, and most of the current route determination methods do not consider these information
