Abstract

The invention provides a road traffic information recording server and a GPS user terminal. In the invention, a traffic information acquisition system based on user information establishes files of each user by collecting the information of common routes of users, driving preference and the like, provides individualized traffic information service to the users and collects the information of the position and the speed of vehicles of the users in the course of traveling to generate the jam information of a road, wherein the user information is used for enhancing the precision of data acquisition so that the generated jam information of the road is more accurate than the traditional floating car system in the course.

Description

technical field [0001] The present invention relates to a road traffic information collection system, and more particularly, to a road traffic information recording server and a GPS user terminal, wherein effective road traffic information is recorded based on user preference and / or historical record information. The invention introduces a method and system for generating road traffic information by using floating user data and floating user preference information. In particular, a method and system for generating road congestion information by using floating user data and floating user preference information are introduced. In the present invention, a floating user is a person or a vehicle that moves on the road and can upload data to the center through a terminal device. The data of a floating user is provided by a floating user moving on the road. It contains at least three kinds of information, user number , time information, location information. The floating user prefe...
