Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a comprehensive management system for traffic safety facilities such as traffic lights, road signs, and road markings.

[0002]

2. Description of the Related Art Conventionally, in order to ensure traffic safety and smooth flow of vehicles, police have installed traffic safety facilities such as a large number of traffic lights, road signs and road markings along the road to regulate traffic. Was going on. These traffic safety facilities
Due to the road safety facilities being installed along the road,
The role does not end, but the role can be fulfilled through proper maintenance after installation. In particular, the installation and renewal of applicable traffic safety facilities must be carried out promptly and reliably in accordance with changes in traffic regulations.

However, the conventional management of this kind of traffic safety facility is usually managed by a ledger. In addition, in the conventional management by the ledger, since the management of the signs and markings is all done manually, it takes a lot of time for all the work, and it is easy to make mistakes in the complicated design and the integration of construction costs. was there.

In addition, it is difficult to say that it has been possible to sufficiently cope with the management of road traffic which has become more sophisticated in recent years. For example, when a sign is damaged due to a traffic accident or the like and urgent repairs are required, it may be time-consuming to prepare the necessary documents for repair work by referring to the ledger that is managed individually. Takes too much.

Further, even if the design drawing of the sign is saved, its attribute data is not saved, or the contents of the design drawing and the contents of the attribute data are different,
In some cases, there was a discrepancy between the data. Furthermore, in the conventional management, since it is written on a normal map, it is difficult to see when the installation location is located at the joint of the pages of the map, and it is written on a page different from the adjacent sign. There was also a problem that it was difficult to capture the relationship between the two.

Further, in the conventional ledger system, traffic regulation, signs, and markings are managed in individual ledger list formats, and thus are not linked to each other. In addition, since the signs and markings are only described as marks on the map, the attribute data and detailed data of the design status are not included, and the entire traffic safety facility is
It was difficult to manage it centrally and visually.

[0008] Furthermore, since the idea of unifying the traffic regulation and the signs and the markings to manage them in a unified manner has not been established, the signs and the markings installed based on a certain traffic regulation are not established. In order to extract just enough, it was necessary to refer to all of the management ledgers. Further, when a new traffic regulation is performed, it is a difficult and time-consuming task to confirm whether or not there is a contradiction with existing signs and markings.

In addition, the CPU is used to manage road auxiliary equipment such as drains and guardrails.
The one described in Japanese Patent Application Laid-Open No. 10-31416 is known. What is disclosed in the publication is "a map storage means for storing a map and a graphic arrangement of road auxiliary equipment on a map for each of a plurality of geographical areas, and a display and a dimension value of the road auxiliary equipment for each of the plurality of geographical areas. Based on the search condition input from the input means over the plurality of geographical areas, the facility storage means to store in, the search condition input means, the display and the dimension value of the road auxiliary equipment stored in the facility storage means. Search means for searching, a totaling means for totalizing the step value of the search result by the searching means, a map and a graphic arrangement stored in the map storage means, a search result by the searching means and the totalizing means A management system for road incidental equipment, characterized in that it has a means for outputting a counting result. "

[0010]

As described above, conventional traffic safety facilities are usually managed by a ledger, and even if they are computerized by using a CPU,
The actual situation is that the data of the conventional ledger management is converted into electronic data as it is, and the problem is that there is originally no system to perform centralized management of traffic safety facilities such as traffic regulations and traffic lights, road signs, and road markings. there were.

An object (object) of the present invention is to carry out centralized management and update work by creating a database relating traffic control facilities and traffic safety facilities such as traffic lights, road signs, and road markings together with road map data. It is to provide a system that can be easily used. It is another object of the present invention to provide a system that enables even a person who does not have special knowledge about a computer to easily plan and place an order for inputting into a database and updating road signs and road markings using the database.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION A configuration of a traffic safety facility management system of the present invention will be described with reference to FIG. In FIG. 1, reference numeral 1 is a computer for a traffic safety facility management system of the present invention, and a stationary computer 1-1 or a portable notebook computer 1-2 is used. In particular, in the case of a 1-2 notebook computer, the notebook computer is moved to an arbitrary place in the field and a GPS signal using an artificial satellite shown in 6 is provided in the GPS provided in the notebook computer. A receiving unit (not shown) receives the data, and various input operations can be executed while indicating the current position on the map data.

Reference numerals 2-1 to 2-8 denote various databases formed on the storage device, which are a map DB and a traffic regulation D, respectively.
B, sign DB, marking DB, traffic light DB, accident DB, other DB, parts DB are included and linked to each other via a database link 7. Traffic regulation DB, sign D
Detailed attribute data of each of B, the marking DB, and the traffic light DB is accumulated. In the parts DB, C
AD data is accumulated. Reference numeral 3 is a system control file in which a program for operating the traffic safety facility government system is stored. Reference numeral 4 is a printer that outputs a plan / ordering form that accompanies updating of signs and markings, and 5 is a data output unit that outputs electronic data.

Further, in the map DB2-1 of the database, detailed map data mainly on roads are accumulated in relation to the surrounding houses and buildings. Also, this map DB
Is linked to the position data by the GPS signal, and when the portable notebook computer is taken out to the field, the current position can be indicated on the map displayed on the display unit of the computer.

The traffic regulation DB 2-2 stores various traffic regulations for each road or each region. Then, using the traffic regulation data, for example, a one-way road,
It is possible to display the range of the speed limit of 50 km / h and the like together with the road display on the map together with the sign and the sign. Therefore, if there is a sign or sign that does not comply with the regulation, it can be easily found. Further, when a new sign or sign is installed or changed from the conventional one, it is possible to automatically eliminate the sign or sign that does not conform to the regulation by using the program.

In addition, the data of all road signs is stored in the sign DB 2-3, and the data such as the installation position, installation time, type, color and size of each sign is stored for each sign and each installed road. It is managed so that various statistics such as

In addition, the data of all road markings are accumulated in the marking DB 2-4, and the data such as the installation position, the installation time, the type, and the size of each marking can be obtained for each marking and each installed road. It is managed so that various statistics can be obtained.

Data of all traffic signals are stored in the traffic signal DB2-5, and data such as the installation position, installation time, type, etc. of each traffic signal are stored in various statistics such as each traffic signal and each installed road. It is managed so that it can be taken.

The accident DB2-6 and other DB2-7 are
Although not directly related to this traffic safety facility management system, it will be used as a reference material for updating traffic safety facilities by accumulating data such as road position and time of accident data.

The component DB 2-8 stores individual data such as traffic signals, road signs and road markings, and stores not only the type and size thereof, but also individual prices and the like as data. It is effectively used when planning and ordering new or updating traffic lights, road signs and road markings.

Next, with respect to the procedure for designing and ordering road signs using the traffic safety facility system of the present invention,
An example will be described. In the storage means of the traffic safety facility management system (either internal storage means or external storage means is possible), map DB of the database, traffic control DB, sign DB, marking DB, traffic light DB, accident DB, other DB, parts DB , Map data, existing regulation data, and traffic safety facility data are stored.

By selecting a predetermined map screen, a road map is read from the map DB 2-1 and displayed as shown in FIG. Then, on this map screen, the existing signs, displays, and traffic lights are read out from the signs DB2-3, the display DB2-4, and the traffic lights DB2-5, respectively, and are regarded as similar to the actual shape as shown in the drawing. Is displayed.

First, from the map screen of FIG. 2, create a sign (H)
When is selected, the screen shown in FIG. 3 is displayed. (Step S1) Here, a case will be described in which a new sign is installed next to a sign that prohibits traffic in the designated direction. Next, on the screen in Figure 3,
The installation position of the sign or sign to be installed is confirmed by pointing with a mouse or a cursor as indicated by a cross in the figure. The determined position is recorded in the database in latitude and longitude based on the position data by the GPS system. (Step S2)

The screen is changed by the operation of step S2 as shown in FIG. On this screen, a window showing the input items of the input screen of the newly installed or changed sign or display attribute is displayed on the screen. An example of the details of this window is shown in FIG. This attribute data can be input using the input items shown in the figure (for example, sign type, jurisdiction,
Enter the major construction name, construction period number, route name, target object name, etc.) from the keyboard. (Step S3)

The screen is changed to the CAD screen of FIG. 6 by step S3. On the CAD screen, the selection of each sign is
It can be easily executed by selecting from the accumulated DAC data with a mouse or the like. (Step S4) On the screen of FIG. 6, the sign map before construction and the sign map after construction are displayed side by side. At this time, the attribute data input in step S3 is displayed on the same screen.

On this screen, the construction cost is automatically calculated and can be displayed on the same screen. When the blueprint before or after construction is changed, it is automatically recalculated and redisplayed. In addition, the unit price for the construction is registered in advance.

When the CAD design in step S4 is completed, the screen changes to the screen shown in FIG. On this screen, the sign map designed in step S4 is displayed side by side with the sign map before and after the construction on the road map displayed on the screen.
(Step S5)

When the sign is actually changed after the construction is completed, the sign before the work is deleted from the database so that only the sign after the work is registered in the database.
(Step S6) Even after the construction is completed, the sign before the construction can be saved as a past state for reference.

Next, an installation diagram of road markings will be described with reference to FIG. When repainting road markings (crosswalks), first display a map including the corresponding road positions on the screen as shown in FIG. 2, and the conventional road markings are displayed on the screen by accessing the map DB and the marking DB. Is displayed in.

In FIG. 8, not only the pedestrian crossing and the stop line,
Notice signs and even stop letters are displayed on the road on the screen. In addition, the length of each road marking is also organized and recorded in the database for each corresponding road and each type of marking.

Therefore, when the road marking is repainted, the drawing of FIG. 8 also serves as a construction order slip, and the construction cost can be easily calculated by multiplying the unit price of the repainting work. Needless to say, if the position of a pedestrian crossing or the like is changed on the input screen, the new marking position is recorded on the map data.

As described above, in the traffic safety facility management system of the present invention, by linking various data accumulated in the database, on the map displayed on the display screen,
Using the CAD system, it is possible to easily draw and input the marking map and the marking map without any special expertise.

Then, on one screen, the current sign map (sign) and the post-construction sign map (sign) are arranged side by side,
Since it can be displayed in different colors, it is possible to have a phase relationship depending on the construction content.

Further, when the post-construction sign (display) diagram is designed, the cost for the construction is automatically calculated by simply inputting the quantity, and the construction cost and the result of the calculation are shown in the same drawing. It can also be displayed above. Then, the construction cost and the like can be output as a printed matter.

Further, in the traffic safety facility management system of the present invention, it is possible to easily move from the map screen to the sign and sign design screen. Since the operation moves to the CAD screen when a predetermined point on the map is selected, a marker and a sign corresponding to the selected CAD data are displayed at that point. Since the map screen (data) has a function as a ledger, a visually superior ledger different from the conventional list-type ledger can be obtained. Further, by executing the design of the sign and the sign from the map screen, an attribute data ledger in which the attribute data of the sign and the sign are registered is automatically created.

[0041]

According to the present invention, by having the structure described in claims 1 to 7, the drawings before and after construction can be displayed on the same screen in the design work of signs and markings. Can be easily grasped, and rationalization and accuracy of work can be achieved. Further, the cost can be accumulated by directly calculating the computer directly from the design screen using the prices of the individual signs and markings registered in advance. Therefore, in designing and ordering of signs and markings, it is possible to significantly reduce working time and reduce human error.

Also, the signs and markings are CAD-printed on the map screen.
By displaying the data, it is possible to visually grasp the contents of the sign and the marking together with the position information. Further, since it is possible to visually grasp the surrounding road condition and the relationship with the building, it is possible to realize the proper installation of the sign and the sign.

CAD of signs and markings displayed on the map
When the data is selected, the attribute database of signs and markings linked to the CAD data is displayed, so that it is not necessary to refer to the map database and the attribute database separately. Further, by clarifying the link between the CAD data and the attribute data, the contradiction between the data is resolved. Also, when a specific sign or sign is selected from the list of attribute data, the CAD data on the linked map is switched to, so there is no need to separately manage the drawing DB and the attribute DB.

When a specific traffic regulation is selected from the traffic regulation DB, the linked signs and markings are displayed as CAD data on the map, so that it is possible to clearly understand the traffic safety facility based on each traffic regulation. Become.

According to the eighth and ninth aspects of the present invention, a program for operating the traffic safety facility management system of the present invention and a recording medium storing the program can be obtained.
