  A car navigation system is known that displays an icon indicating a facility such as a hotel or restaurant on a screen of an output device (display or the like) together with a map so that the position of the facility on the map can be understood (Patent Document 1).

Japanese Patent Laid-Open No. 7-270171

In addition, the applicant displays an icon indicating a traffic information board that is installed on a road and displays a traffic information such as a congestion state or a construction advance notice on a vehicle traveling on the road. We developed a traffic-related information display device that displays the map along with a map on the screen of the output device.
However, in the conventional display method of the traffic related information display device, there is a problem that it is difficult to grasp whether the traffic information board provides the traffic information to the vehicle traveling in the upward direction or the downward direction of the road.
So, for example, even if you want to extract a traffic information board that provides information only to vehicles traveling up the road, which of the traffic information boards installed on the road I couldn't easily figure out what to do.

FIG. 9 is a screen diagram showing an example in which a conventional traffic related information display device displays an icon indicating a traffic information board together with a map on the screen of the output device.
In FIG. 9, “TIB1” to “TIB6” indicate traffic information boards, and “L001” to “L007” indicate road sections that are sections between adjacent intersections on the road.
The icons indicating the traffic information boards “TIB1” to “TIB6” have a pattern in which letters are written in a square, and the letters “multi-pattern” indicate a multi-pattern traffic information board. The letters “free pattern” indicate a semi-free pattern traffic information board. Here, the multi-pattern traffic information board is an information board that displays characters, symbol marks, symbols, etc. by remote control from the traffic control center, and the semi-free pattern traffic information board is a traffic information board. It is an information board that displays the display contents registered in advance by selecting the pattern number from the traffic control center.

For example, although it can be seen that the traffic information board “TIB1” is installed in the road section “L001”, the traffic information board “TIB1” is trafficked to the vehicle traveling in the upward direction (from the bottom to the top in FIG. 9) of the road section “L001”. It is impossible to grasp whether the information is provided or whether the traffic information is provided to the vehicle traveling in the downward direction (from the top to the bottom in FIG. 9).
Therefore, even if it is desired to extract a traffic information board that provides information only to vehicles traveling in the upward direction of the road section “L001”, the traffic information board “TIB1” installed in the road section “L001”. And “TIB2” could not be easily known.

  The present invention has been made in view of such circumstances, and a traffic-related information display device capable of easily grasping whether a traffic information board provides traffic information to a vehicle traveling in an installation road. The purpose is to provide.

  The traffic-related information display device according to the first aspect of the present invention is an icon, which is a pictograph indicating a traffic information board that is installed on a road and displays and provides traffic information on a vehicle traveling on the road, at the installation position of the traffic information board.

Means (Claim 1).

Here, the pictogram includes a design and a character.
According to the first aspect of the invention, the traveling direction of the vehicle that the traffic information board provides traffic information is different in shape depending on whether it is up or down the road where the traffic information board is installed. Since the icon is displayed, it is possible to easily grasp whether the traffic information board provides the traffic information to the vehicle traveling in the upward direction or the downward direction of the road.

  The display means may display the icon having a different shape according to the extending direction of the road (claim 2).

In the display method of the conventional traffic related information display device, when the traffic information board is installed near the intersection, it is determined which of the plurality of roads flowing into the intersection is the traffic information board. There was a problem that it was difficult.
For example, in FIG. 9, it is difficult to grasp whether the traffic information board “TIB1” is installed in the road section “L001”, the road section “L002”, the road section “L003”, or the road section “L004”. .
On the other hand, in the first invention, since icons of different shapes are displayed according to the extending direction of the road where the traffic information board is installed, even if the traffic information board is installed near the intersection, It is possible to easily grasp the road on which the traffic information board is installed.

  The display means is configured to display the icon on the screen of the output device, and the display means further displays a pointer, which is a pictograph for indicating an arbitrary position on the screen, on the screen. The display unit is configured to display, and includes an operation unit that receives an operation of moving the position of the pointer on the screen, and the display unit has a position indicated by the pointer on the icon by the operation received by the operation unit. If it is moved to, information based on the traffic information displayed on its display surface by the traffic information board corresponding to the icon may be displayed on the screen (claim 3).

In the conventional traffic-related information display device, when the operator moves the mouse pointer over the traffic information board icon and clicks the icon with the mouse, the traffic information displayed on the traffic information board is displayed. Although the contents could be displayed on the screen of an output device such as a display, it was necessary for the operator to perform a two-stage operation, and the operation load was high.
On the other hand, in the first invention, the operator simply moves the mouse pointer on the traffic information board icon and displays the contents of the traffic information displayed on the traffic information board on the screen of the output device. Therefore, it is not necessary for the operator to further click the icon with the mouse, and the operation load on the operator can be reduced.

  The display means may display the icon having a different shape according to the type of the traffic information board.

The conventional traffic related information display device is complicated because the type of the traffic information board cannot be recognized unless the characters written on the icon of the traffic information board are read.
On the other hand, according to the first invention, icons of different shapes are displayed according to the type of the traffic information board, so that the type of the traffic information board can be easily recognized without reading the characters described on the icon. Can do.

  A computer program according to a second aspect of the present invention provides an icon, which is a pictograph indicating a traffic information board provided on a road and displaying traffic information on a vehicle traveling on the road, at the installation position of the traffic information board. A computer program for functioning as a traffic-related information display device for displaying on a corresponding map, the computer depending on the direction of travel on the road of the vehicle on which the traffic information board is to provide the traffic information In order to function as display means for displaying icons of different shapes (claim 5).

  The computer program of the second invention is substantially the same computer program as the first invention.

Depending on the combination, it is selected which icon of FIG. 4 is used, and the icon is overwritten on the map displayed above based on the “installation position” information in the extracted traffic information board information for display. To do.

  On the other hand, when displaying the traffic information board 7 with the icon shown in FIG. 6, the calculation unit 101 first refers to the information of “installed road section ID” in the extracted traffic information board information for display, Information on the road section corresponding to this “installed road section ID” is extracted from the map information stored in the storage unit 102, and from the start point / end point / interpolation point position information of this road section, from the start point of this road section A direction toward the end point (upward direction) and a direction from the end point of the road section toward the start point (downward direction) are calculated. Then, the display surface of the traffic information board 7 travels in any of the 16 directions in FIG. 6 based on the up and down directions and the “up / down” information of the extracted display traffic information board information. Calculate whether it is directed to the vehicle. Then, the icon of the traffic information board 7 is selected according to the direction and the “type” of the extracted display traffic information board information, and the “installation position” information of the extracted display traffic information board information is selected. Based on the above, the icon is overwritten on the map displayed above.

  For example, in the case of the traffic information board 7 “TIB1” with the traffic information board ID “0001”, since the installed road section ID is “L001”, the information of the road section “L001” is extracted from the map information. A direction from the start point of the road section to the end point (upward direction) and a direction from the end point of the road section to the start point (downward direction) are calculated. As a result of the calculation, if the upward direction is approximately north-northeast and the downward direction is approximately south-southwest, the traffic information board 7 “TIB1” is “uphill” as the traffic information board 7 “TIB1”. Is calculated to be directed to the vehicle traveling in “4 (upper)” of the 16 directions in FIG. 6. Since the traffic information board 7 “TIB1” is “multi-pattern”, the multi-pattern traffic information board icon corresponding to “4 (upper)” is selected. Since the installation position of the traffic information board 7 “TIB1” is (X1, Y1), the selected icon is overwritten and displayed at the position (X1, Y1) on the map displayed above.

  Next, when the operator moves the mouse pointer onto the icon of the traffic information board 7 displayed on the screen of the output device included in the display unit 103 using the mouse included in the operation unit 105, the calculation unit 101 Extracts the information of the traffic information board 7 from the display traffic information board information stored in the storage unit 102, refers to the “display information content”, and displays the traffic information displayed on the traffic information board 7 The icon indicating the content of the traffic information is created and displayed near the icon of the traffic information board 7.

  In the above-described embodiment, the configuration has been described in which icons indicating the multi-pattern traffic information board and the semi-free pattern traffic information board are displayed on the screen of the output device, but the present invention is not limited thereto. Furthermore, it may be configured such that icons of different shapes are prepared for various traffic information boards such as a free pattern type traffic information board and a dedicated pattern type traffic information board and displayed on the screen of the output device. Here, the free pattern type traffic information board is an information board that can display any character within 15 characters (for example, “20 minutes from here to □□ intersection”) by remote control from the central device 2. The dedicated pattern type traffic information board is an information board that displays a specific character (for example, “20 minutes”), a figure, etc. by variable display of a part of the information board and remote control from the central device 2 It is.
