DB 50 is established.
[20] This mapping may be done periodically or at a specific point in time, such as when the bus route, base station and road information are updated.
[21] In addition, the terminal location information receiver 180 receives location information from the mobile terminal 190 through the base station 230, and the terminal location information manager 150 stores the location information received by the terminal location information receiver 180. The terminal location information DB 60 is constructed based on the information of the base station information DB 40 for each bus route and the information DB 50 between the base station and the link.
[22] The traffic information collector / processor 160 collects traffic information based on information of the base station information DB 40 for each bus route, the information DB 50 between the base station and the link, and the terminal location information DB 60. The traffic information DB 70 for each driving section is established by grasping the speed of the vehicle, and the information of the traffic information DB 70 for each driving section is provided to the traffic information user 210 and the bus company 220. As information for display, a mapping information DB 80 between a link and a section for providing traffic information including speed information by mapping information between a road link and a section of a base station is constructed.
[23] In addition, the traffic information distributor 170 provides traffic information of the mapping information DB 80 between the link and the section to the traffic information user 210 and the bus service company 220.
[24] The driving route manager 110 of the traffic information collecting system having the above configuration manages a bus operating company and a bus of the driving company.

It stores and manages information such as ID, link name, link length, link type code, start node ID, end node ID, number of lanes, speed limit and link traffic.
[28] Then, using the information of the DB managed by each of the managers 110 to 130, the mapping information generator 140 substantially constructs information necessary for generating traffic information in advance.
[29] The DB previously constructed includes a base station information DB 40 for each bus route and an information DB 50 between a base station and a link, and the base station information DB 40 for each bus route includes a route number and a bus type classification (high speed / long distance), It includes information such as bus dispatch time, order of base station list by route, corresponding base station ID and distance between previous base station, and information DB 50 between the base station and the link includes information such as base station ID and link ID.
[30] In such a state, the terminal location information receiver 180 receives the location of the bus in real time whenever the mobile terminal 190 mounted on the bus in operation moves between the base stations. The location information is transmitted to the information manager 150, and the terminal location information manager 150 is based on the information constructed as described above, the number and bus ID of the mobile terminal 190, the report date and time, the ID of the corresponding base station, Location information of the terminal such as latitude, longitude, zip code and address is calculated.
[31] The calculation result is stored in the terminal location information DB 60 and provided to the traffic information collector / processor 160.
[32] Then, the traffic information collector / processor 160 receives the speed information of the bus based on the information of the terminal location information DB 60, the base station information DB 40 for each bus route, and the information DB 50 between the base station and the link. It extracts traffic information for each section of the base station, which includes section ID, section name, start base station ID, end base station ID, start link ID, end link ID, section length, collection date and time, and traffic speed. It is stored in the traffic information DB 70, where the section refers to the space between the base station and the base station.
[33] In addition, the traffic information collector / processor 160 may display the section ID, the link list order by section, the link ID, the number of location coordinates, the X coordinate, and the like for display information provided to the traffic information user 210 and the bus company 220. Information about the Y coordinate is stored in the mapping information DB 80 between the link and the section.
[34] When the traffic information is collected in the above manner, the traffic information distributor 170 may provide the information when the traffic information user 210 and the bus service company 220 request the traffic information through the wired / wireless Internet network. It is.
[35] As described above, the traffic information collection system according to the present invention should grasp the location information from the mobile terminal mounted on the bus moving the corresponding line.
[36] In the present invention, the location information of the bus is extracted in the following manner.
[37] First, as shown in FIG. 3, bus location information may be extracted using a hand-off function of a mobile communication network switch.
[38] Hand-off refers to making a call without disconnection even when a mobile terminal moves between a cell and a cell, which is a service area of a mobile communication network service.
[39] At this time, the location of the mobile terminal is detected through the base station where the hand-off has occurred to determine the location of the bus.
[40] The bus speed is extracted using the time at which the hand-off occurs and the interval distance between the base station.
[41] That is, in FIG. 2, when the bus equipped with the mobile terminal moves along the line and moves from the section of the base station a to the section 300 passing from the section of the base station b to the section of the base station b, the switching station of the mobile communication network automatically performs a hand-off function. (S500).
[42] At this time, the terminal location information receiver 180 transmits the location information of the terminal and the time at which the hand-off has occurred to the terminal location information manager 150, and this information is stored in the terminal location information DB 60 (S510).
[43] Further, if the bus continues to move and moves from the base station b to the base station c to the section 400, the hand-off occurs again (S520), and similarly, the time at this time is stored (S530).
[44] Then, the traffic information collector / processor 160 extracts the speed of the bus by using the difference between the stored time and the interval distance between the base station b (S540).
[45] Second, as shown in FIG. 4, the mobile terminal can extract the location information of the bus by notifying the base station at a predetermined time interval.
[46] When the mobile terminal mounted on the bus informs the base station at a regular time interval, the base station knows which bus is present in the section of the base station, and when the base station is changed, the speed is extracted using the moving time and the section length of the base station. .
[47] For example, if the mobile terminal of the bus informs the base station of location A at point A of FIG. 2 and informs the location at point B, then announces the location at point D (S550, S560), points A and B belonging to the same base station. The speed of the bus is extracted using the time difference informed at the point and the interval length of the base station a (S570).
[48] To be precise, the speed must be extracted by using the time difference between points A and C and the section length of base station a. However, the moving speed of the bus according to traffic conditions and the time interval at which the mobile terminal mounted on the bus notifies the base station. Some errors may occur.
[49] In general, the distance between base stations is 500m, and the distance between two stations can be entered on a bus line.
[50] If the mobile terminal mounted on the bus reports the location at regular intervals, it uses the time when the base station changes, and uses the interval time and the interval length of the base station before the base station changes. To extract the velocity.
[51] As described above, the method of extracting location information of the bus may be alternative to the method of FIGS. 3 and 4, or other methods including the two may be used in combination.
[52] Generally, base stations of mobile communication networks are installed on major road axes.
[53] In view of this, the main roads to collect information in the traffic information collection system according to the present invention are highways and main roads, and mobile terminals are installed on expressways and intercity buses that regularly operate the highways and main roads. Traffic information is collected using the location information of the base station of the mobile communication network installed along these highways and major national roads.
[54] As described above, the present invention has an effect of simply collecting real-time traffic information using an existing mobile communication network by mounting a mobile terminal on a bus running a certain line.
[55] In addition, by providing information about the bus route to the bus service company in real time, there is an effect of efficiently managing the bus operation.
