As shown in the table of bus stops (Bus_Stop_Seq) for each route, B, C, and D, which constitute route 1, are the first, second, and third stops of route 1, respectively.

In the case of the section identifier (Section_ID), the bus stop BC of section 1 is section 1, the CD section 2, the DC section 3, the CB section 4, the bus section AC of section 2, section 5, and CE section 6 The EC can be described as the interval 7, and the CA can be described as the interval 8. Hereinafter, a method of providing real-time bus operation information (RT_BSI) in five embodiments according to each description method will be described.

<Example using bus stop identifier>

15 illustrates a method of providing real-time bus operation information (RT_BSI) using a data broadcasting network according to an embodiment of the present invention.

First, the data broadcasting terminal 40 includes a bus stop information (Bus_Stop_Info) including a bus stop name (Bus_Stop_Name) and a bus stop identifier (Bus_Stop_ID), a route construction stop including a list of bus stops per route and a list of bus stop identifiers for each route. A first step S10 of storing the list Bus_Route_Info is performed.

The bus stop information Bus_Stop_Info may be a matching table of the bus stop name Bus_Stop_Name and the bus stop identifier Bus_Stop_ID as shown in FIG. 4. The route construction stop list Bus_Route_Info may be expressed as a list of bus stop identifiers Bus_Stop_ID constituting the route, as in the case of route 1 (2, 3, 4, 3, 2).

Unlike the bus stop information (Bus_Stop_Info) and the route configuration stop list (Bus_Route_Infro), unlike the real-time bus operation information (RT_BSI), since the information is not changed at any time, the broadcast is provided as data embedded in the data broadcasting terminal 40 in advance or transmitted at a low frequency. Preferably provided as data.

14 shows an example of the data configuration of actual bus stop information (Bus_Stop_Info). Where <intunti> is 1 byte, <intunli> is 2 bytes, and <intunlo> is information having a data length of 4 bytes. The bus stop information Bus_Stop_Info may be configured to have various additional detailed information such as the bus stop name Bus_Stop_Name and the bus stop identifier Bus_Stop_ID as well as actual coordinate information. Since the bus stop information Bus_Stop_Info is non-real-time data, for example, a large amount of data may be broadcast before and after 0 o'clock, the time when the bus stops.

13 shows an example of the data configuration of the route construction stop list (Bus_Route_Info). As shown, the route construction stop list (Bus_Route_Info) is generated and sent in units of routes, and is a service identifier indicating <intunti> (id) of 1 byte indicating the route construction stop list (Bus_Route_Info) information, and the corresponding data component for error checking. 2 bytes of <intunli> (n), which is information indicating the total data length of the section of route construction stops by section, 1 bytes of <intunti> (m), which is information indicating the number of bus stops constituting the route, and each And m * <intunlo> of m * 4 bytes, which is a bus stop identifier list. Since the route construction stop list Bus_Route_Info is also non-real-time data, a large amount of data can be broadcast before and after 0 o'clock, for example, when the bus stops.

Next, a real-time bus including a bus stop identifier Bus_Stop_ID in which buses 10 belonging to each line are in proximity, based on the location information of a plurality of buses 10 currently operated by the traffic control station 20. A second step S20 of periodically generating driving information RT_BSI is performed.

The traffic control station 20 collects current location information of all operating buses 10 in the area serving as bus service information service through, for example, GPS information transmitted from the bus 10 or beacons installed at bus stops. . By using the collected information, the traffic control station 20 determines the bus stop identifier Bus_Stop_ID adjacent to the bus 10 of each line. According to the example of FIG. 3, the bus stop D, that is, the bus stop identifier 4, the bus stop identifier 4 and the bus stop bus Bus_2, the bus stop B, that is, the bus stop identifier 2, performs the real-time bus operation. The information RT_BSI is generated periodically.

6 shows an example of the configuration of real-time bus service information RT_BSI based on the bus stop identifier Bus_Stop_ID. As shown, the real-time bus service information (RT_BSI) is generated in units of routes and is <intunti> (id) of 1 byte, which is a service identifier indicating the real-time bus service information (RT_BSI), and information indicating the total data length of the corresponding data component. 2 bytes of <intunli> (n), 4 bytes of <intunlo> representing the bus line unique number, 1 byte of <intunti> (m), which is the total number of buses operating the line, and proximity to each bus location. And m * <bus_route_information_using_bus_stop_id> of m * 4 bytes, which is a bus-by-bus proximity bus stop list composed of a bus stop identifier Bus_Stop_ID.

According to this embodiment, since the location information is generated using the bus stop identifier Bus_Stop_ID having a significantly smaller data amount than the coordinate information of the actual bus 10 or the bus stop name Bus_Stop_Name, real-time bus operation information RT_BSI. Not only can significantly reduce the amount of data, but because the traffic control station 20 reprocesses the location information of the bus 10 based on the bus stop, a large amount of the bus 10 in the data broadcasting terminal 40. It provides an effect that can reduce the computational burden and computation time required to display the location according to the acquisition of the coordinate information for.

Next, the data broadcasting station 30 performs a third step S30 of transmitting real-time bus service information RT_BSI to data broadcasting.

Finally, the data broadcasting terminal 40 receives the real-time bus operation information (RT_BSI) and refers to the bus stop information (Bus_Stop_Info) and the route construction stop list (Bus_Route_Info) in real time bus operation information (Bus_Stop_Name) based on the bus stop name (Bus_Stop_Name). A fourth step S40 of providing the user with RT_BSI is performed.

On the other hand, it is more preferable that the traffic control station 20 generates not only location information of the bus 10 but also operation time information (Section_Travel_Time) for each section in each section between bus stops. Referring to the generation method of section time information (Section_Travel_Time) as follows.

First, the traffic control station 20 performs a fifth step of periodically generating operating time information (Section_Travel_Time) for each section by measuring the operating time for each section based on the location information of the bus 10 collected for each time zone in a route unit. In addition, the data broadcasting station 30 performs a sixth step of transmitting section time travel information (Section_Travel_Time) by data broadcasting, and the data broadcasting terminal 40 receives section time travel information (Section_Travel_Time) and provides it to the user. Perform the seventh step.

Since the traffic control station 20 continuously grasps the location information of the bus 10, it is possible to easily calculate the operating time of the section between each bus stop. 11 shows an example of the data configuration of the travel time information (Section_Travel_Time) for each section. Section time travel information (Section_Travel_Time) is also generated for each route, <intunti> (id) of 1 byte which is a service identifier indicating section time travel information (Section_Travel_Time) for each section, and information indicating total data length of the corresponding data component. 2 bytes of <intunli> (n), 4 bytes of information indicating the bus line's unique number (not shown), 1 byte of <intunti> (m), which is the number of stops constituting the route, followed by each section M * <intunli> (travel_time), etc., of m * 2 bytes representing a time list.

Meanwhile, in the first step S10, in order to improve the user's convenience, it may be configured to further store route additional information (Additional_Service_information) which is detailed information on each route. As shown in FIG. 12, the additional line information (Additional_Service_information) is configured to further store additional line information including at least one of a bus carrier name, a first train time, a last train time, a train interval, fare information, and a round-trip point in a line unit. It is preferable.

The real-time bus operation information (RT_BSI), which is important for rapid update of information in order to improve the efficiency of data operation and provide real-time bus operation information that is convenient for the user, is at least three times more frequent than the operation time information (Section_Travel_Time) for each section. It is preferable to send by. In addition, the real-time bus operation information RT_BSI is transmitted at least five times higher than the frequency of sending the bus stop information Bus_Stop_Info and the bus stop identifier list Bus_Route_Info, which are information that is not required for quick update of information. desirable. According to this embodiment, the data channel limited to bus operation information can be used more efficiently.

<Example using bus stop sequence>

Embodiments described below differ only in the method of describing the above-described bus stop identifier Bus_Stop_ID and the location information of the bus 10, and other parts are the same, and thus, repeated descriptions thereof will be omitted.

First, the data broadcasting terminal 40 includes bus stop information Bus_Stop_Info including the bus stop name Bus_Stop_Name and the number of bus stops constituting each route and bus stop sequence number Bus_Stop_Seq for each route. A first step S10 of storing the route construction stop list Bus_Route_Info is performed. Bus stop number (Bus_Stop_Seq) for each line indicates how many bus stops each bus stop corresponds to each line as shown in the table of FIG. 5.

Next, the bus stop sequence number (Bus_Stop_Seq) of each bus line of the bus stops in which the buses 10 belonging to each line are arranged in line units based on the location information of the plurality of buses 10 currently operated by the traffic control station 20. A second step S20 of periodically generating real-time bus operation information RT_BSI including a) is performed.

According to the example of FIG. 3, in the case of bus 1 of route 1, bus stop D, that is, the third bus of route 1, and in the case of bus 2, bus_2, are bus stop B, that is, the first bus stop of route 1, in real time. The bus operation information RT_BSI is generated periodically.

7 shows a configuration example of real-time bus service information RT_BSI based on the bus stop sequence Bus_Stop_Seq. As shown, the real-time bus service information (RT_BSI) is generated in units of routes and is <intunti> (id) of 1 byte, which is a service identifier indicating the real-time bus service information (RT_BSI), and information indicating the total data length of the corresponding data component. 2 bytes of <intunli> (n), 4 bytes of <intunlo> representing the bus line unique number, 1 byte of <intunti> (m), which is the total number of buses operating the line, and proximity to each bus location. And m * <bus_route_information_using_stop_sequential_number> of m * 1 bytes, which is a proximate bus stop list for each bus including the bus stop sequence Bus_Stop_Seq.

According to this embodiment, since each data component is generated for each line and the bus route unique number is included as basic information, the bus stop sequence number (Bus_Stop_Seq) of one byte which is less data than the 4 byte bus stop identifier (Bus_Stop_ID) of the first embodiment. ) May be used to generate location information of the bus 10. Therefore, the data amount of the real-time bus operation information (RT_BSI) can be significantly reduced, and since the traffic control station 20 reprocesses the location information of the corresponding bus 10 based on the bus stop, the data broadcasting terminal 40 It provides an effect that can reduce the computational burden and computation time required for the position display according to the acquisition of the coordinate information for a large amount of bus 10 in the.

Next, the data broadcasting station 30 performs a third step S30 of transmitting real-time bus service information RT_BSI to data broadcasting.

Finally, the data broadcasting terminal 40 receives the real-time bus operation information (RT_BSI) and refers to the bus stop information (Bus_Stop_Info) and the route construction stop list (Bus_Route_Info) for real-time bus operation information based on the bus stop name (Bus_Stop_Name). A fourth step S40 of providing the user with RT_BSI is performed.

<Example using section identifier>

First, the data broadcasting terminal 40 includes bus section information (Section_Info) including a bus section name (Section_Name) and a section identifier (Section_ID) between bus stops, and a section identifier constituting the number and sections of sections constituting each route. A first step S10 of storing a route configuration section list Bus_Route_Info including a list of Section_IDs is performed. The section refers to the section between the bus stops as described above, it is preferable to divide by each route, and in the case of a round-trip route, it is more preferable to divide the up and down lines into different routes.

Next, based on the location information of the plurality of buses 10 currently operating by the traffic control station 20, the section identifiers (Section_ID) corresponding to the sections in which the buses 10 belonging to each line are currently located, are provided in line units. A second step S20 of periodically generating real-time bus service information RT_BSI is included.

According to the example of FIG. 3, the bus stop D, the bus stop D, that is, the bus stop D, the bus stop D, the bus stop D, and the bus stop D, the bus stop D, the bus stop D, and the bus stop D, the bus stop information are periodically generated. .

8 shows an example of the configuration of the real-time bus service information RT_BSI based on the section identifier Section_ID. As shown, the real-time bus service information (RT_BSI) is generated in units of routes and is <intunti> (id) of 1 byte, which is a service identifier indicating the real-time bus service information (RT_BSI), and information indicating the total data length of the corresponding data component. 2 bytes of <intunli> (n), 4 bytes of <intunlo> indicating the bus line unique number, 1 byte of <intunti> (m), which is the total number of buses operating the line, and current location information for each bus. And m * <bus_route_information_using_section_id> of m * 4 bytes, which is a neighbor bus stop list for each bus, which is composed of a location section identifier (Section_ID).

According to this embodiment, there is a disadvantage in that bus section information (Section_Info) is required. However, since each data component grasps location information of the bus 10 by using section information generated for each route and divided up and down, a more accurate real-time bus. The driving information RT_BSI may be provided.

Next, the data broadcasting station 30 performs a third step S30 of transmitting real-time bus service information RT_BSI to data broadcasting.

Finally, the data broadcasting terminal 40 receives the real-time bus operation information (RT_BSI) and refers to the bus section information (Section_Info) and the route configuration section list (Bus_Route_Info), based on the bus section name (Section_Name). A fourth step S40 of providing the user with RT_BSI is performed.

In the second step (S20), the traffic control station 20 is based on the location information of the plurality of buses (10) currently operating the bus stop in which each of the buses 10 belonging to each line in a route unit near each departure Real-time bus service information RT_BSI is generated periodically including an identifier (Start_Bus_Stop_ID) and the bus stop identifier (End_Bus_Stop_ID) to arrive.

9 shows an example of the configuration of real-time bus service information RT_BSI based on the departure and arrival bus stop identifier Bus_Stop_ID. As shown, the real-time bus service information (RT_BSI) is generated in units of routes and is <intunti> (id) of 1 byte, which is a service identifier indicating the real-time bus service information (RT_BSI), and information indicating the total data length of the corresponding data component. 2 bytes of <intunli> (n), 4 bytes of <intunlo> representing the bus route unique number, 1 byte of <intunti> (m), which is the total number of buses operating the route, starting with location information for each bus And m * <bus_route_information_using_section_of_bus_stop_id> of m * (4 + 4) bytes, which are a start and arrival bus stop list consisting of a bus stop identifier Start_Bus_Stop_ID and an arrival bus stop identifier End_Bus_Stop_ID.

<Example using departure and arrival bus stop sequence>

This embodiment uses a second bus stop sequence (Bus_Stop_Seq) as described above, except that the departure bus stop sequence (Start_Bus_Stop_Seq) and the arrival bus stop sequence (End_Bus_Stop_Seq) are used to provide more accurate bus service information. Since it is the same as the embodiment, hereinafter, only portions that differ from the second embodiment will be described.

Next, based on the location information of the plurality of buses 10 currently being operated by the traffic control station 20, the bus stop sequence number of the bus stops of the bus stops from which the buses 10 belonging to each route departed, respectively ( A second step S20 of periodically generating real-time bus service information RT_BSI including Start_Bus_Stop_Seq) and the bus stop sequence number End_Bus_Stop_Seq of each route of the bus stop to arrive is performed.
