Method for road one-way restriction and traffic state identification based on floating car technology

Abstract

The invention provides a method for road one-way restriction and traffic state identification based on floating car technology, which is characterized in that a larger number of floating cars equipped with GPS and other vehicle-mounted positioning systems periodically acquire and then return the information related to automobile number, position, direction and speed to a data center in the process of traveling, the information is filtered to obtain road traffic data and extract a dynamic first characteristic factor of road one-way restriction and traffic, the system performs data digging on a road traffic database simultaneously in order to obtain a statistical second characteristic factor of road one-way restriction and traffic in relevant time window, and the system can identify the road one-way restriction and traffic state automatically by matching the first characteristic factor with the corresponding second characteristic factor. The method of the invention can provide dynamic and accurate information related to the change of road one-way restriction and traffic state for various traffic information service systems, has the advantages of low cost in acquiring information and timely and reliable information updating, and is significant to various traffic information service systems.

Description

【Technical field】 [0001] The invention belongs to the field of information technology application. Specifically, it involves the identification method of one-way traffic restriction and traffic status of roads in the traffic information service system, and provides dynamic traffic information services of one-way traffic restriction and traffic status for public travel. 【Background technique】 [0002] Floating car technology, also known as "probe car", has been widely used. Its basic principle is: based on the vehicle's position, direction and speed information regularly recorded by the floating car equipped with on-board GPS during its driving process, the application of map Matching, path estimation and other related computing models and algorithms are processed, so that the floating car position data and urban roads are associated in time and space. At present, in public travel and other traffic information service systems, one-way road restrictions and traffic status cha...
