It shows the practicality of the service. Traffic information provided by the running vehicle is transmitted to the base station, and the data is transmitted to other service using vehicles requesting traffic information after calculation through the server.

4) Fig. 4 Server Configuration

It shows the configuration of the server that handles the comprehensive operation. And a transmitter / receiver for transmitting and receiving data transmitted from each mobile Internet base station, a controller for receiving and controlling data therein, a synthesis unit for synthesizing respective data, and an operation unit for calculating each data.

The purpose of this service is to use a portable Internet terminal device, which will be commercialized in the future, so that a large number of users provide their own driving information to a database and provide data back to other users in real time so that there is no need to build a database or collect information. By implementing a system that can provide services that are somewhat cheaper than the existing traffic information service, and providing the most accurate service in real time, the navigation function is used to proceed as well as the current situation of the road desired by the user. It aims to be able to understand the current situation of the planned road.

The existing road traffic information system used the method of providing the service through wireless internet and GPS using the sensor or wireless CCD camera installed on the main road, and the traffic information provided by Korea Expressway Corporation. However, the service provided by the wireless internet using the CCD camera can be used only in the limited area where the user has a very high wireless internet fee using the mobile phone and the CCD camera is installed. In addition, when directly using the CCD camera video, additional service costs are required to pay a very expensive service fee. The service provider has the disadvantage of not only developing a dedicated terminal that can provide services and a server for operation, but also investing a lot of money initially by installing a CCD camera in each region. In the case of the services provided by the Korea Expressway Corporation, the excessive use of the service fee for the wireless Internet service fee and the time difference for providing the service occur a lot, so it is not possible to cope with the constantly changing road conditions in real time so that efficient traffic information can be used. There is no problem.

The present invention is designed to solve the above-mentioned conventional problems, eliminating the costs incurred to obtain traffic information in order to provide a conventional service, and using a user's driving information as a data to provide a low-cost service in real time. It is developing GPS software that can use the mobile internet terminal device that can provide the traffic information that is changed to the mobile phone. The server that can be linked with the mobile internet base station can identify the traffic situation by using the data provided by the mobile internet terminal device. To develop.

The present invention frequently transmits its current driving state to a portable Internet base station in a state where a driver having a portable internet terminal device is connected to the portable internet base station. GPS is installed inside the portable Internet terminal device to determine location information and transmit data to the nearest base station at regular intervals. In the portable Internet base station, the mobile station receives the movement position per unit time, and the calculated speed information is transmitted to the server through the nearest portable Internet base station and recorded in the database. The server records and aggregates the data transmitted from each base station. The calculated database is transmitted to the mobile internet base station in real time, and is sent to the driver who owns a mobile internet terminal that is currently operating in the same region or a road in another region, so as to receive vehicle movement speed or road conditions between roads. Not only that, it is a function that can search the driving information of the desired road by using Navigation.

Each driver transmits their driving status to the server in real time through the mobile internet base station. Receives comprehensive driving information to maintain smooth traffic conditions, reduce travel time for traffic jams to the minimum, and transmit data while the driver is driving, thus maximizing the accuracy of data. There is no separate database collection cost because it is used.

In order to implement the object of the present invention, a server which stores a database to be transmitted from each vehicle and aggregates each database, and a portable Internet base station and a portable Internet terminal device to be commercialized later are needed. In case of service provider, it is necessary to establish a server that can receive and operate database, and need GPS and Navigation software for this service inside PDA that user will use. Do. After connecting to the server, the portable Internet terminal transmits its own driving database to the portable Internet base station at regular intervals. The mobile Internet base station can determine the moving speed of the current road by measuring the moving time using a database transmitted for a predetermined time from the terminal device and measuring the moving distance using the GPS function of the terminal device. In addition, by using the navigation function installed inside, it is possible to select the driving road by identifying the shortest road that can reduce the driving time by searching the situation of the current road as well as other roads that are going to operate. .

1. National Traffic Information                     

The characteristic of this service is that service information of service user is used as data. Since the existing traffic information providing system uses CCTV and sensors, the service can be provided only in limited roads and areas, so it is impossible to obtain traffic information on various routes that service users cannot obtain because the traffic information of various roads desired by service users cannot be obtained. On the other hand, in the case of this service, since the traffic information can be obtained from all the roads operated by the subscriber, it can be expected to obtain the road information of various routes in the nationwide area.

2. Low cost of collecting traffic information

Existing traffic information service requires expensive information collection cost due to initial investment and management cost related to CCTV and sensor installation cost and wireless internet using mobile phone, so service users need expensive service fee. In the case of this service, the service user transmits his / her own driving status and uses it as traffic data by using a mobile internet terminal device which will be commercialized later. have. In addition, since the service is provided using a low-cost Internet service fee using a mobile Internet service, it can be expected to provide a very affordable service to the service user.

3. Real-time traffic situation service

In the case of the existing traffic information service, since the service is provided after accessing the service providing server using a mobile phone, a time difference occurs until the user accesses the server again after using the first traffic information service. Therefore, it has a disadvantage that the service can be used only at the time desired during the driving, and thus it has a disadvantage in that it cannot cope with the traffic situation changing in real time. On the other hand, in the case of this service, it provides data while transmitting its own driving status and is provided with the service in real time while accessing the service server, so it can react sensitively to road traffic conditions that change frequently. Not only can this service lead to a smooth road traffic situation, but also the shortest time route can be selected, so the service users can expect to reduce fuel costs and utilize the best operating time.
