Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a public transportation information processing system according to the present invention.

Referring to the drawings, the system is largely divided into the first and second databases 10 and 20, the public transportation management processing unit 30, the public transportation analysis processing unit 40, the output processing unit 50 and the public transportation guide processing unit 60. It consists of.

As shown in Table 1, the first database 10 is constructed of spatial data of the most basic area in the system.

As shown in FIG. 2, the above spatial data are divided and stored in three types of vector formats. Information indicating a point such as a bus stop or a taxi stand is in the form of a point (a), such as a road network or a bus lane. Linear geographic information is constructed by line (b), and geographic information such as parks and administrative districts is constructed by polygon (c).

In addition, major facilities can be represented as points by sign projection on large scales and represented as polygons along the outline of buildings in large scales to be represented in different vector formats according to map accumulation.

The main facilities are divided into 11 layers, and the classification (legend) for each layer is shown in Table 2.

The second database 20 is constructed with the attribute data of the region, the attribute data of the region includes a bus station database as shown in Table 3, a bus route database as shown in Table 4 and a route route database as shown in Table 5.

In Table 4, the bus route length in the above attribute data is geographic information and is basically included in the line attribute.

In addition, in Table 5, 'direction ID' has a bidirectional progression in the case of a general bus route, but in many cases, it is used to distinguish various route types.

The public transportation management processing unit 30 may change some data such as facility search, bus stop property change, facility information view, facility name change, etc. based on the data constructed in the first and second databases 10 and 20. To provide.

With reference to the drawings looks at each function of the public transport management processor 30.

First, the facility search function performs a search for each bus stop in the facility and region constructed in 11 layers, as shown in Table 2. When the user selects the facility search function, the search is performed as shown in FIG. Provides an input window for entering a condition. When the facility type and the search keyword are input through the input window and a search execution command is given (when the 'Next' button is selected), all the facilities including the string of the main search keyword are displayed as a list as shown in FIG. 3B. In this case, if the desired facility is not included in the list, the user may return to the previous state so that the user can re-enter the search keyword through the 'previous' button. If the desired facility is displayed in the list, the user selects the desired facility and clicks the 'OK' button to center the selected facility so that the local map can be displayed. At this time, the map is enlarged and displayed at a preset magnification.

In the process of performing the bus stop property change function, when the user selects a function and selects a bus stop to change the property on the map, the input window as shown in FIG. 4 is provided so that the property can be changed. 2 Information of the database 20 is updated. In the input window, the input section is displayed to change the bus stop name and detailed name, and an option box (⊙) is displayed so that any one of the bus stop types can be selected. In addition, the presence or absence of bus bays, rest facilities, guides, and token sales tables are indicated through check boxes (□).

The facility information view and the facility name change function provide an input window showing the type of the facility and the name of the facility as shown in FIG. 5 when the user selects the facility information view function and selects one facility on the map. In this case, the facility name is provided with a text box so that the user can change it, and the user changes the contents in the facility name text box and presses the 'save' button to update the property information of the second database for the facility.

In addition, the public transportation management processing unit 30 builds a foreground image of the bus stop in the first database 10, and after selecting a bus stop image viewing function by the user, selecting one bus stop on the map, Provide the foreground image.

The public transportation analysis processing unit 40 provides a function of analyzing the current state of the road and processing the result so that the result can be provided. In other words, it performs road traffic density analysis, redundancy analysis between bus lines and search for bus stops around facilities.

The analysis of road route density and bus route overlap is used to help decision making when planning a new bus route or modifying an existing bus route. In addition, searching for bus stops around facilities can be used to establish new bus stops or to plan existing bus stops.

Hereinafter, each function of the public transportation analysis processor 40 will be described with reference to the accompanying drawings.

First, the route redundancy analysis function provides an input window for receiving a search condition as shown in FIG. 6A when the user selects the route redundancy function. The input window is provided with a standard bus route number input field and a target bus route number input field. In addition, after the user inputs the bus route number in each of the two input spaces, pressing the 'OK' button provides a result window indicating the analysis result as shown in FIG. 6B. The result window displays the total length of the analysis line, the length of the overlapping section of the analysis line and the target line, and the proportion of the overlapping section in the whole section. The algorithm used in the analysis of the route redundancy is that the database structure of the bus route is a combination of each stop and street segment, and these street segments have a departure node, an arrival node, and a section length. If the same record is found for the departure node and the arrival node, the search result can be provided through the result. Also, after the result of redundancy of the route is provided through the above process, if the user selects the map view according to the analysis result, the overlapping section can be easily identified by displaying the color of the entire section and the overlapping section differently on the map. .

The process of performing a function of searching for bus stops around facilities provides an input window as shown in FIG. 7A when a user selects a function of searching for bus stops around facilities. The input window basically provides a facility search function. In addition to the facility search function, a buffer function selection check box (□) and a desired radius input space and bus stop search check box (□) are provided. If you want to be displayed as a buffer in the input window as above, check the buffer check box (□). If you want to search the bus stop near the facility using the buffer, check the bus stop search check box (□). When the user selectively enters the facility name to be searched and each search condition and presses the 'Next' button, a list including the string of the entered keyword is displayed as shown in FIG. 7B. When the user selects a facility from the list and clicks the 'OK' button, all bus stops within the user-specified radius around the facility are displayed again as shown in 7c. In addition, on the map, it finds the facility designated by the user and displays the bus stop with a buffer in a different color from the bus stop outside the radius. Here, the buffer is displayed as much as the user wants based on the outline of the building, and when there are several buildings such as an apartment complex, the buffer is displayed based on the outline connecting all the buildings.

The road route density analysis function calculates the density of the route passing through the street section using data such as road width, lane, and passing rower. The density is calculated as the density per lane and the density per 1M of the width, and is calculated by the following equations (1) and (2).

The output processor 50 provides a function of processing the bus route to be output. The output includes attribute information related to the bus route, such as the route type, route length, dispatch interval, number of buses and type of bus. In addition, the output processing unit 50 allows not only the bus route but also the basic diagram of the region.

The function of the output processor 50 will now be described with reference to the drawings.

First, in order to output the bus route, when the user selects the bus route output function while the area map screen is opened, an input window for receiving the bus route number is provided as shown in FIG. 8A. When the user enters the bus route number in the input box and presses the 'OK' button, the route display for the entered bus route number is displayed on the map of the region as shown in FIG. 8B. If the bus lines diverge in the middle or at the end of the line, they are displayed in a different color so that the user can easily identify them. Meanwhile, at the bottom, information about the starting point, the end point, the route length, the number of running lines and the dispatch interval is searched in the second database and added to the table. When the user selects a print command while the screen is displayed, the map displayed on the screen can be printed.

In addition, in order to output the area base map, the user opens the area map on the screen, and if the base map output function is selected, the map of the entire area is displayed on one screen. At this time, the guide line for the output is displayed as shown in Figure 9a. When the user selects a cell of a location to be output, a map of the selected cell is displayed on the screen as shown in FIG. 9B, and when a print command is selected, the map displayed on the screen can be printed.

The public transportation guidance processor 60 performs a function of providing corresponding public transportation usage information from the first and second databases 10 and 20 according to the input search condition. At this time, as a method for guiding public transportation information, the user can perform a route search by inputting a bus route number and a facility search by input of facilities. In addition, the terminal point search can be performed by inputting a departure and arrival stop. In particular, the model point search guides the distance from the departure point to the arrival point, as well as the number of stops, and the direction of the bus.

With reference to the drawings looks at the function of the public transport guide processor 60.

The public transportation guidance processing unit 60 is divided into a frame that allows input of a search condition on a part of the screen and a frame showing a map, as shown in FIG. 10A. The function is executed, and route search function is performed by selecting the 'route search' tab. The figure shows that the 'Facilities finder' tab is currently selected. In the 'Find Facility' tab, a facility type selection box and a facility name input box are provided, and a passage search check box (□) is provided.

With reference to Figure 10 looks at the facility search and guidance process,

First, select the type of facility you want to find in the facility type selection (for example, educational facility), enter a search term (for example, 'medium') in the facility name input field, and press enter. All facilities will be searched and displayed in a list at the bottom. If you select a facility from the list, the facility is centered on the map on the right. If the Pass Route Search checkbox is checked, all bus routes passing through the facility are searched and the route bus number is displayed by route bus type in the route bus number display window below the list. When one of the route bus numbers displayed on the route bus number display window is selected, the selected route is indicated by a thick line on the right map.

The route search function is developed when the 'route search' tab is selected as shown in FIG. 11A, and is divided into a route search and a departure-destination route search. There is also a route bus number display window and route route check box (□) at the bottom.

In the above configuration, the route finder selects the stop name through the mouse or the user directly enters the stop name with the keyboard and sends a search execution command to search all the bus lines passing through the stop and display it in the route number display window at the bottom. . If any route bus number is selected in the route number display window, the line of the selected number is displayed on the map on the right in bold line. Here, it is not necessary to input all of the search keywords when the keyboard is input. If only a specific character included in the stop name is input, the list of stops including the specific string is displayed through an auxiliary window shown in the drawing.

On the other hand, the starting point-destination route search method is similar to the route finding method, except that two stop names should be selected with only the starting and destination stop name input fields.

Looking at the search and guidance process of the departure-destination route search with reference to Figure 11a as follows.

When the user selects or inputs the name of the starting point and the destination of the destination using the mouse or the keyboard, respectively, and the search execution command is transmitted (selecting the "Search Route" button), the bus route number from the starting point to the destination is displayed on the route display window. If any route bus number is selected (mouse clicked) in the route display window, the line of the route bus number selected on the map on the right is displayed in bold lines.

If you want to know the distance from the starting point to the destination and the intersection and bus stop to go through, check the Show route route check box as shown in Fig. 11b and select the bus route from the route bus number display window. Then another window shows the intersections and bus stops from the starting point to the destination of the bus number in that order, along with the cumulative distance from the starting point to the destination.

In the above, the system designed to be used in a PC (Porsonal Computer) is shown, and the public transportation guidance processing unit according to the present invention is constructed as a web server together with the first and second databases, and uses public transportation through the Internet as shown in FIG. The guidance system is achieved.

As described above, the public transportation information processing system according to the present invention can systematically construct public transportation related information and provide bus routes analysis and detailed information to the user so that the public transportation administrator can make a reasonable decision. In addition, it is possible to provide convenience to users of public transportation.
