Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment of the present invention will be described in detail.

1 is a block diagram of an intelligent traffic information collection system using GPS terminal location information according to the present invention.

As shown in Figure 1, the intelligent traffic information collection system according to the present invention and the GPS terminal 10; Information processing server 20; Information storage server 30; Location collection server 40; And an LSB server 50.

The GPS terminal 10 includes the input / output, storage, radio transmission and reception functions and control functions like the general mobile communication terminal, and further includes a GPS reception function for receiving GPS signals from satellites. GPS reception may be implemented using a wireless communication chip having a GPS function.

At this time, the GPS terminal 10 may have any form as long as it has a GPS receiver and a control unit of the above-described functions. That is, it is a broad concept including all terminals such as cellular phones, PCS, IMT-2000, PDA, GSM or CDMA.

The information processing server 20 processes the information by combining the subscriber location information and the additional service information stored in the information storage server 30, and transfers all the processed information to various terminals (e.g., WEB, WAP, voice). It is converted into a form that can be displayed and displayed.

The information storage server 30 stores a subscriber number list of the location to be checked, and the location collection server 40 interoperates with the LSB server 50 connected to the existing switching network system to request location information and to be notified of the response. , And serves to store it as the information storage server 30.

The LSB server 50 serves to provide the location number server 40 with the terminal number, location information (latitude / longitude), and positioning time of the GPS terminal 10 identified through the switching network.

2 is a flowchart illustrating a method of providing and utilizing intelligent traffic information using GPS terminal location information according to the present invention.

First, the location collection server 40 requests the information storage server 30 for the subscriber number list of the location to be checked according to a predetermined condition (S110).

At this time, the condition that the location collection server 40 can request the information storage server 30 can be set as follows.

First, you can request a subscriber number that has elapsed a certain time from the previous subscriber location checking time, and second, you can request a subscriber number of a specific location using the previous location information of the subscriber. You can request an expected subscriber number.

Fourth, it is possible to request a subscriber number in which the short-term moving distance of the subscriber has rapidly increased.

Here, the condition of the first subscriber number is requested periodically, for example 5 minutes, 10 minutes, and the remaining conditions (second to fifth) can be requested aperiodically to maintain the freshness of the information.

In this state, the location collection server 40 requests the subscriber information of the location object to the location-based service (LBS) server 50 linked with the existing switching network system (S120).

Thereafter, the LBS server 50 notifies the location collection server 40 of the terminal number, location information (latitude / longitude), and positioning time of the GPS terminal 10 identified through the switching network (S130). .

At this time, the location collection server 40 converts the collected location information into local information mapped to the latitude / longitude and stores the location information in the information storage server 30 (S140).

Thereafter, the information processing server 20 processes the information by combining the subscriber location information and the additional service information stored in the information storage server 30 (S150). At this time, the processing method of the information is as follows.

First, it is possible to process the vehicle average moving speed information of the road using the subscriber's mobile coordinate information and time. This is to calculate the moving speed of the vehicle by averaging the speed information when the terminal corresponding to the previous location and the current location of the terminal corresponds to the designated road section.

Second, it is possible to process the optimal movement route information between specific points using the vehicle speed information for each road. This uses the movement speed DB by road to derive the optimal movement route based on time.

Third, it is possible to process the arrival time information to the destination considering the vehicle moving speed for each road. This measures the time required for each section by using the moving speed DB for each road and calculates the time required for arrival to the destination as a sum.

Fourth, it is possible to process road traffic jam section information using the location distribution of the subscriber station. This provides vehicle location information concentrated in a specific area by using the current location information of the terminal.

Fifth, the road guidance information to the destination using the subscriber location information can be processed. It processes the information of the future movement direction by using the current location information of the subscriber.

Sixth, data information for driving and travel information may be processed in consideration of the expected vehicle movement route. This will provide speeding guidance using speed information for each subscriber, future traffic area travel information and travel information using previous and current locations.

Finally, all the information processed in the information processing server 20 is converted and displayed in a form that can be delivered to a variety of terminals, the user selects the desired information to obtain the optimal information for them (S160)

At this time, the information processed by the information processing server 20 is converted so that it can be displayed not only through the GPS terminal 10 but also through various communication terminals including WEB, WAP, ARS, and the like.

As described above, according to the present invention, it is possible not only to reduce the enormous cost required for the construction of the existing ITS system, but also to shorten the time and expand and promote additional services that meet the needs of various customers.

Therefore, in the present invention, it is possible to build a low-cost and high-efficiency traffic information system by utilizing the location information and the movement route of the GPS terminal.
