Description

Real-time traffic information providing system and method using traffic information detecting device for each section {SYSTEM FOR PROVIDING REALTIME TRAFFIC INFORMATION BY USING SECTION CLASSIFIED MEASUREMENT APPARATUS AND THE METHOD THEREOF}

The present invention relates to a traffic information providing system and a method thereof, and more particularly, a driving road of a vehicle using a plurality of traffic information detection devices installed on a roadside and exchanging traffic information data with each other. And a traffic information providing system for providing a driver with customized traffic information on an adjacent road and a method thereof.

Due to the recent rapid increase in vehicles, traffic congestion has become a serious social problem. In order to solve the traffic congestion, the traffic congestion is introduced by providing an intelligent transport system (ITS) that provides traffic information to vehicles in real time to distribute traffic.

However, in order to provide such real-time traffic information, information such as driving speed and position of the vehicle is collected by using a mobile communication device equipped with a GPS (Global Positioning System) receiver. There is a need for a central information center that analyzes the collected information and organizes and provides real-time traffic information.

The traffic information service system provided with the central information center will be described with reference to FIG. 1.

A mobile communication device such as a personal handheld information terminal equipped with a GPS receiver in a vehicle and a vehicle terminal are sensed to detect information about a driving speed and a position of the vehicle. When the detected information is transmitted to the central information center 502, the central information center 502 collects and analyzes the information to construct real-time traffic information. The traffic information thus configured is transmitted to the mobile communication device and the vehicle terminal 501 through the mobile communication network 503. The mobile communication device and the vehicle terminal 501 output the traffic information through a liquid crystal display or a speaker (not shown) so that a driver can recognize the traffic information.

However, in order to service real-time traffic information, the above-mentioned system needs to establish a central system that collects and analyzes traffic information transmitted from all regions and guides traffic information of each road in the country. Therefore, since the system requires a central server that requires a large capacity and high performance processing capacity, high cost is required to construct the system, and when the central server fails, the entire system is paralyzed and thus cannot provide traffic information. There is this. In addition, since the central server processes the traffic information of the entire area takes a lot of load, there is a problem that can not provide accurate information in accordance with the neighborhood of the area where the individual vehicle passes. In addition, in the case where the central server is installed in a certain area unit, there is a problem that it is difficult to provide traffic information of another area when the jurisdiction of the central server passes through another border area.

As one example, Korean Patent Laid-Open Publication No. 2006-0059364 (published on June 2, 2006) includes a vehicle detector installed on a road at a point where traffic information is to be detected and detecting a vehicle to wirelessly transmit a detected signal. A repeater for generating basic data from a signal received by the vehicle detector and transmitting the basic data to a predetermined position through a communication network; and a central control unit for controlling the repeater through the communication network and transmitting traffic information to a predetermined position from the basic data transmitted to the repeater. Disclosed is a system for collecting and providing traffic information comprising a server and a client for requesting necessary traffic information by accessing the central server through the communication network and receiving traffic information transmitted by the central server.

However, the traffic information collection and provision system measures the traffic information of each zone with a vehicle detector and transmits all the traffic information to the central server, and the central server analyzes it and transmits the analyzed traffic information to individual clients. In case of failure of the central server, it is difficult to provide traffic information to the client.

Accordingly, a first object of the present invention is a traffic information detecting apparatus for measuring and exchanging traffic information in each section of a traveling direction of a terminal provided in a vehicle and the vehicle equipped with the terminal, analyzing and guiding the traffic information to the terminal. It is to provide a traffic information providing system to guide the real-time customized traffic information using.

A second object of the present invention is to use a traffic information detecting device for measuring and exchanging traffic information in each section of the traveling direction of the terminal provided in the vehicle and the vehicle equipped with the terminal, analyzing and guiding the traffic information to the terminal. It provides a traffic information providing method to guide the real-time customized traffic information.

In order to achieve the first object of the present invention described above, in an embodiment of the present invention, a terminal provided in a vehicle to receive traffic information of the vehicle, and installed on a roadside to measure traffic information related to the flow of the vehicle. In addition, a traffic information providing system including a plurality of traffic information detecting devices for transmitting and receiving each other, and transmitting the traffic information on the driving direction of the vehicle to the terminal.

In order to achieve the above-described second object of the present invention, in an embodiment of the present invention, (i) the traffic information detecting device searches for a terminal provided in a vehicle traveling on its own section, and then Generating data by measuring the first basic information of the child section related to the flow; and (ii) the traffic information detecting device requests the adjacent traffic information detecting device according to the traveling direction of the vehicle to the second basis of the other section.

Transmitting information data to the terminal, and (iii) the terminal receiving the traffic information data and transmitting the same to the driver. The law is provided.

According to the present invention, it is possible to provide customized traffic information data to a vehicle in operation in real time, and continue to provide overall traffic information even when a failure occurs in a traffic information detection device of a certain section or an error occurs in a central server. Can be. In addition, the central server for managing the entire traffic information is not necessarily required, so the installation cost of the system is substantially reduced.

In addition, since the central server is not necessarily required, a problem arises due to a change in the subject of collecting and managing traffic information, for example, a change of the manager of the central server in a border area of an administrative area. Poor delivery, etc.).

Hereinafter, with reference to the accompanying drawings will be described in detail a method of analyzing the sun area of a building according to preferred embodiments of the present invention. In the drawings below, like reference numerals in the drawings indicate, in principle, like elements.

In describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.
