Description

  The present invention relates to a road sign management program for checking and managing the installation location, type, installation status, consistency of display contents, and the like of road signs installed on a road.

The management of road signs is handled by the country, prefectures and municipalities for each road to which the sign belongs. In each local government, one road sign for each road under its jurisdiction describes the sign photo, installation date, installation status, etc. in the ledger, and the road manager actually understands the current situation. When doing so, the corresponding road sign page is searched from the ledger and the work is compared with the situation at the site.
JP 2002-62152 (3rd page, FIG. 1)

  Currently, the environment surrounding roads is constantly changing due to changes in place names and the creation of new roads, etc.Along with this, new signs are also installed on road signs to guide various road conditions. Or to replace it. However, on the other hand, it was very cumbersome and troublesome to search the corresponding road sign countlessly in the road network and repeat the work of checking the ledger each time. There was a problem that was delayed. In addition, in the electronic map application that is commercially available or the navigation system that guides the route to the destination mounted on the car, the actual road sign installation status and the consistency of direction indications cannot be grasped. It was almost unusable in managing signs.

  The present invention was invented in view of the above problems, and provides a road sign management program capable of quickly and easily managing road signs by reproducing the actual road sign installation state on a map image. It is in.

  According to the first aspect of the present invention, the computer displays the map image data, the road sign image data, and the road sign book data in the database, respectively, and displays the map image data extracted from the database on the screen. Map display means, based on the request data from the user, the corresponding road sign image data is listed from the database, and only the specific road sign image data is superimposed on the map image data and displayed on the screen Means, reading the direction designation data from the road sign book data corresponding to the road sign image data, and the direction of the map image data and the road sign image data with respect to the road sign installed on the actual road Image editing means for rotating and displaying on the screen so that the destination indicated by It characterized in that to function Te.

  The map image data is a concept including address book data such as roads and residences displayed on the map. The road sign book data is a description of various information related to individual road sign image data stored in the database (sign type, installation point, direction designation data indicating the display state of the road sign image data, etc.). . Further, the screen refers to the screen of the display device. In addition, when a road sign image is displayed on an actual road so that the orientation on the map image and the destination indicated by the road sign image are the same, the road sign image is displayed on the map screen. On the screen, it is displayed as seen from the driver who actually travels on the road.

  In addition, when making a request to this program to display a specific type of road sign in the desired area, the user can check various items displayed on the screen and derive the display result. Alternatively, a method of inputting a keyword such as a road name or an intersection name and deriving a search result is selected. Furthermore, when the direction designation data is read, the road sign image data registered in the road sign book data is directly reflected on the map image data. For example, a specific road sign image is designated with a pointing device on the screen. Then, road sign book data corresponding to the road sign image can be extracted on the screen.

  When formed in this way, specific road sign image data listed based on the user's request is displayed on the screen so as to overlap the map image data, and the displayed road sign image data is actually Since the direction on the map is the same as the road sign installed on the road sign and the destination indicated by the road sign is also rotated and displayed in the same way, the user can grasp the installation status of the road sign at a glance.

  According to the present invention, the road sign image data on the map image data is displayed in a state where the direction and the destination are matched in accordance with the road sign where the corresponding road sign image is actually installed on the site. Because the user can grasp the actual road sign installation situation at the site at a glance, there is no need to check a huge amount of road sign books accumulated as paper materials one by one. The time required for searching the road sign book is drastically reduced, and as a result, road sign maintenance and management can be performed quickly and efficiently.

  Next, an embodiment of a road sign management program according to the present invention will be described in combination with a configuration of a processing device for operating this program based on each drawing.

First, the structure of the processing apparatus 1 for operating the road sign management program of this invention is demonstrated below. Specifically, the processing apparatus 1 is as shown in FIG.

(3) Various interfaces for inputting / outputting various data to / from the processing device 1 (for example, a modem device, a LAN port, a USB port, etc.) 4,
(4) A display device connected to the interface 4 and displaying the editing data 18 as a user interface screen (hereinafter referred to as a screen) 50, and a printer for printing out one screen of the screen 50 on printing paper. Including output device 5,
(5) The input device 6 including a pointing device such as a mouse or a keyboard is constituted by the devices (1) to (5).
Reference numeral 7 is a ROM for reading various data, reference numeral 8 is a RAM for accessing various data, and reference numeral 9 is a device for reading an external storage medium such as a CD-ROM or MO.

  Next, the modules 10a, 10b, 10c, 11 stored in the storage device 2, and the map-related database 12 and the road sign-related database 13 will be described with reference to FIG.

  First, the map-related database 12 stores map image data 14 and address book data 15 describing information on existing locations of houses and roads (for example, Nakagawa ○ chome × address, Takaoka City, Toyama Prefecture). In addition, the user can voluntarily register the update of the map-related database 12 and the registration of new information, but in general, the latest version of the map image data 14 and address book data 15 are stored from a software house or the like. A method is selected in which a storage medium such as a CD-ROM is distributed, or the data 14 and 15 are rewritten by network distribution via the Internet. Next, the road sign related database 13 stores road sign image data 16 and road sign book data 17 respectively.

  Then, the data synthesis modules 10a, 10b, 10c, as shown in the flowchart of FIG. 3, map image data 14, address book data 15, road sign image data 16, road sign register stored in the databases 12, 13 described above. The data 17 is extracted based on the request data 19 from the user on a “road sign display condition setting” screen 30 described later, and the request conditions (road name and intersection name, road sign type, installation date, etc.) are used. After the corresponding map image data 14 and road sign image data 16 are narrowed down, the address book data 15 allocated to the map image data 14 and the road sign image data 16 are collated, and the address book data 15 and 15 match. That can process the display of the road sign image data 16 superimposed on the map image data 14 To generate the data 18.

  Next, FIG. 4 to FIG. 7 show specific processing procedures when the road sign management program is actually operated. In addition, the description of this processing procedure is displayed on the screen 50 after the processing of each data 14, 15, 16 is actually performed based on the request data 19 input from the user in the processing device 1 described above. The edit data 18 is shown.

  First, FIG. 4 shows a “Signal image display condition” screen 30 for setting a request condition when the road sign image 16 corresponding to the request data 19 input by the user is displayed on the map image 14. It is. On this screen 30, <installation category> 31 representing the actual road sign installation status, <jurisdiction office> 32 managing roads, <sign type> 33, <sign owner> 34, <route> 35, For each item such as <Installation Date> 36, <Installation Method> 37, etc., a procedure for extracting road sign image data 16 to be displayed on the map image 14 for the items for which the user has turned on each check box 38 is taken. Then, the user actually turns on the check box corresponding to each item, and designates the <Apply display conditions> button 39 with the pointing device. By doing so, the corresponding road sign image data 16 is extracted from the road sign related database 13, and as shown in FIGS. 5 and 6, the corresponding coordinate point that becomes the address book data 15 on the map image 14 is displayed on the screen 50. A road sign image 16 is displayed.

  The configuration of the edit data 18 for displaying FIGS. 5 and 6 will be described. This edit data 18 is represented by coordinate data (for example, x and y) based on the address book data 15 with respect to the road sign image data 16. ) And collated with the coordinate data previously assigned to each of the address book data 15 on the map image data 14, and the two image data 14, 16 of the map image data 14 and the road sign image data 16 are overlapped. Data processing to be combined. Further, when the editing data 18 is generated, the direction designation data 20 for instructing the display direction of the road sign image data 16 on the map image 14 is generated.

  The formation of the direction designation data 20 will be described later with reference to FIG. 7, but there is an item that can process the road sign image data 16 read from the road sign related database 13 on the “Traffic sign register description” screen 40, Here, after the road sign image 16 is rotated in a plane and matched with the display direction of the road sign that is actually installed on the site, the road sign image data 16 that has been subjected to the data processing is again used as the road sign related database. By registering in No. 13, the direction designation data 20 is allocated to the corresponding road sign image data 16.

In FIGS. 5 and 6, the enlarged / reduced display of the map image 14 can be adjusted by raising and lowering the bezel 21 on the right side of the main screen 50. In addition, when the map image 14 is displayed in a wide area, it is assumed that many road sign images 16 are displayed on the screen 50. Therefore, the display state of each road sign image 16 is displayed by the switching button 22 on the right side of the screen 50. Can be appropriately changed to a pin 16b (shown as a reference number (eg, H-73-108-4) in FIG. 5) that displays only the reference number.
Reference numeral 23 denotes an end button of the program.

  FIG. 6 is an enlarged view of the map image 14 of FIG. 5 adjusted by the bezel 21 beside the screen 50. In this figure, the road sign image 16 displayed in the direction determined around the intersection is shown. Has been placed. In this case, it can be immediately confirmed that each road sign image 16 is consistent with <notation place name> and <direction indicating destination> on the screen 50. Furthermore, when a pointing device is specified together with each road sign image 16, the screen jumps to the “road sign book” screen 40 of the corresponding road sign image 16, and this screen 40 is displayed in a separate window (see FIG. 7).

  Furthermore, on the “road sign book” screen 40 shown in FIG. 7, in addition to referring to various information related to the road signs actually installed as described above, the information can be updated and newly registered. For example, in addition to changing the <reference number> 41 recognized by the processing device 1 assigned to the individual road sign image data 16 and the road sign ledger data 17, the corresponding road sign management <office name> 42, < After changing various information such as route name> 43, <installation category> 44, <signature number> 45, <installation date> 46, <constructor> 47, <current photo> 48, etc. By designating the <Register> button 49, if the road sign ledger data 17 having the same name as the <reference number> 41 exists, it is overwritten. If not, the road sign related database is newly registered data. Save to 13.

In addition, the “road sign book” screen 40 has an item of <current situation photograph / board surface description item>, and in this item, the road sign image data 16 can be newly read as a current situation photograph. Further, the read new road sign image data 16 can be processed by freely rotating and displaying the image in the item <display sign edit> 20. Then, after the road sign image data 16 is processed in the direction matching the road sign installed at the actual site, the <Register> button 49 is designated on the map image 14 together with the pointing device. The displayed road sign image 16 is also reflected in the display state as it is after the data processing.
The <Delete> button in the screen 40 is used to delete the displayed road sign ledger data 17.

  The <installation category> item is provided with a check list function 61 for actual road signs as shown in FIG. 8. On the screen 60 displaying the check list 61, the relevant road sign register data 17 is displayed. In addition, specific installation conditions other than the attribute (sign type, installation date, etc.) of the road sign are shown in detail for each predetermined item. And the checklist function 61 changes the description contents of each item of the checklist so that the detailed installation status of the road sign can be confirmed in addition to the ○ / × notation that discriminates whether the installation status of the road sign is good or bad An editing function is also provided.

  In addition, this program has a function to list various conditions related to road signs and create a related data list by summing up the conditions (not shown). In this case, it is possible to carry out the counting items (administrator name, sign type, road sign status, etc.) corresponding to the items set by the user, and target all the road sign ledger data 17 registered in the road sign related database 13. Information on road signs actually installed on the site can be obtained from various items, and the totalized data list can be output on a paper by a printer, or interface (LAN, modem device, etc.) 4 from the processing device 1 If it is transmitted to other terminals using the Internet network W via the network, it can be effectively used as road sign management data.

  The road sign management program can be used jointly from a plurality of terminals 71 via the Internet network W. In this case, as shown in FIG. 9, the management server 70 is installed at a predetermined location, the road sign related database 13 is stored in the storage device of the management server 70, and each terminal (for example, this program is installed) By storing the map-related database 12 in the storage device 71, for example, a person in charge of each civil engineering office having a different jurisdiction over the road actually visits the site. Then, the road sign installation status investigated and accessed from the terminal 71 to the management server 70 is input / registered in the road sign book data 17, and the road sign related database 13 is updated so that other persons in charge When the management server 70 is accessed via the Internet network W, the updated road sign ledger data 17 can be viewed, and as a result, a wider and more detailed road sign management system Shekel.
