Abstract

The present invention provides a terminal for collecting traffic information and generating traffic information. The terminal generating a data set and transmitting the data set to a remote traffic information center, wherein the data set includs information about a measurement start point and a travel locus, periodically measured for a predetermined period from the start point, using DR information based on DR and GPS information. The start point includes a vehicle ID, and absolute coordinates and an absolute time at the start point, and the travel locus information includes relative coordinates of each measurement location with respect to a previous measurement location. A method for generating traffic information in a remote traffic information center using information collected from the terminal is also provided. Accordingly, the present invention can reduce the amount of data provided by the terminal to the remote traffic information center, and can generate high-precision traffic information even in an area in which the reception of GPS signals is not possible and GPS signals are weak.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Application No. 10-2007-0122088 filed on November 28, 2007, the disclosures of which are incorporated herein by reference. technical field [0003] The present invention relates to a terminal mounted on a vehicle for collecting traffic information, and a method for generating or processing traffic information at a remote traffic information center using source data collected from the terminal. Background technique [0004] Recently, in order to alleviate the problem of traffic congestion or traffic congestion on roads, a technology for providing road traffic information to drivers in real time has been developed. [0005] The method of providing the traffic information is to obtain the position information of the vehicles from a plurality of vehicles each equipped with a terminal for collecting the traffic information by using the equipment, and the remote traffic informatio...
