Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transportation system using a point number display method.

Currently, many types of maps are being published, but it is quite a laborious task to find a destination point based only on place names on conventional maps, and it is difficult to find a destination point on a conventional map. , I have no idea where it is. Figure 1 shows how inconvenient the current state of relying only on place names is. This will be explained using an example of a car traveling eastbound on National Route N.

A car heading east on National Highway N, heading towards its destination, turned left at the intersection (a) at the intersection (a) according to the atlas, saw a sign for city C, turned left and entered local road R. However, I wasn't sure if I had made a mistake at that intersection, so I continued northward with anxiety. After walking for a while, we came to an intersection (b), where there was a village place name board as shown in Figure 2 (b). So I looked for Village D on the map, but it didn't seem to be listed on the map, probably because it was too small. My anxiety continued to grow, and before long I came to an intersection (c). However, the driver himself was not sure where the intersection was on the map, and when he looked at the direction light display board shown in Figure 2 (c), he went straight ahead and saw only City C, and when he turned right, it only showed City B. I don't know if I will be able to turn right here and reach my destination, JmA Town. So I looked for City B on the map, but unfortunately, City B was not listed on that page but on the next page, so I couldn't find it, so I ended up stopping the car and driving through. I ended up having no choice but to stop the person and ask. Examples like this are nothing special and are something you will experience all the time while traveling. As you can see from this example, the fundamental flaw in the current method is that even if you turn left and go to City C, you don't know if it's in (A) or (D); > Even if I look at the aal, I can't tell where I am.Also, it would be nice if the destination information showed the actual destination, town A, but I've never heard of it before, like city or town C. In most cases, it is displayed as a city.Even if a traveler is given a destination with a place name that they have never heard of, it is difficult to find that place name on a map, and it is difficult to find it on a map. If they cannot be found inside, they are of no use.With this in mind, the Ministry of Construction amended the ministerial ordinance regarding road signs in order to keep them in line with the wave of the age of internationalization. The decision was made to replace road signs across the country by using the Roman alphabet in conjunction with the Roman alphabet.However, the current method of relying only on place names for directions has its limits, even for Japanese people, but this method is especially effective for foreigners. When you think about how useful it is to write in Roman letters, the Hepburn Roman alphabet invented by Americans is different from the original English pronunciation and sounds and is difficult to read even for Anglo-Americans.
I wonder if it will be useful for people in countries other than English-speaking countries where the same letters are pronounced in completely different ways and with different writing systems, such as France, Spain, and Russia.Also, road atlases with Roman alphabets are available at major bookstores. Not there,
Without a road map, I find myself wondering how much of a benefit to internationalization I see when I see a road sign with the name of a place I've never heard of in Roman letters.

In addition to these developments, recently there has been a lot of research into navigation systems that can be used to locate one's own vehicle, as it has a variety of uses. Navigation systems currently being considered include methods that use artificial double layers, the Loran method used for ships, and methods that combine magnets, gyros, and distance meters. However, the satellite method and Lorand method require large-scale receiving equipment because they simultaneously receive radio waves from multiple very distant base points and perform complex calculations to determine the location. Among them, the satellite method has high accuracy but is particularly expensive, and the Loran method is not suitable for mountainous areas or urban areas and is said to lack reliability. @The stone and gyro methods require only relative points, not absolute points, so it is necessary to accurately manually locate the base point, and errors accumulate, making them difficult for the general public to use. There is nothing that can withstand it. Therefore, the emergence of an inexpensive and highly reliable navigation system is awaited. In this way, the overall road transportation system is being reviewed, and part of this effort is the recent gathering of road map-related industries to standardize road maps across the country. The present invention has been made in view of the above.

The basis of the present invention is a transportation system that does not rely on place names. To explain this specifically, as shown in claim v, item 1, the whole of Japan is divided into 1000 or less regions. The reason why we targeted the whole country is because this method is not effective even if we target only some regions, so the number of divisions is 1.
000 or more would be fine, but the reason I chose 1000 or less is that many of the road maps that are commonly used among commercially available maps are about 1/200,000 to 250,000: The 0-division method is used because it is considered appropriate from a practical point of view. Conventional road maps are divided into houndstooth patterns according to the topography to eliminate waste in marine areas. Although there are many cases, it is preferable to divide it into a regular grid if possible in order to facilitate the distance calculation described later. Regarding this division, if there is already uniform division, it may be used. A different three-digit area number between 000 and 999 is sequentially assigned to each divided area. Then, divide the length and width of each divided area into squares of 100 or less, and mark each area as 0.
Two-digit numbers from 0 to 99 are assigned, and the numbers assigned vertically and horizontally may represent line numbers or cell numbers. In reality, it is more convenient for each grid to be a square, as it is easier to calculate distances (described later) and to know directions based on the difference in numbers, and the width-to-height ratio of a general atlas is approximately 10 Because of this, it seems most practical to divide the horizontal direction into 100 equal parts and the vertical direction into 70 equal parts. Furthermore, if the scale is as above, the size of each square is 1km square or 500m square, which is a size that makes it easy to calculate distances, and it is more convenient if all areas are of the same size. So, as an example, 1st square 5
If it is 00m square, the size of one area is 501v horizontally and 35cm vertically.
+s (This is the same as that often seen in general road atlases. In this way, the area is identified by a 3-digit area number and 2-digit numbers each for the vertical and horizontal directions, a total of 7 digits. It represents a point within.

When it is necessary to represent a more detailed point, such as in a partially enlarged view, each square is further divided into 10 equal parts, and three-digit numbers are used for each of the vertical and horizontal lines. In the above example, one square is 50 meters square, and a very detailed area can be expressed. In this case, one digit will be added to each of the vertical and horizontal directions, so the point display will be 9.
It will be expressed as a number of digits. If a method for expressing points throughout the country in a unified and unified manner is determined by the method set forth in claim 1 or 2, then the method set forth in claim 3 can be achieved. Sea urchin, area code and vertical,
It is possible to create a map as shown in the example of FIG. 3 in which a scale corresponding to the horizontal number is placed in the yR box. In addition to the map for each region, this map may also be a partially enlarged map or a map of several regions.As shown in claim 4, the map shown in FIG. b) (b) (
As in the example shown in Figure 4 (a), (c), the a-mushi board shown in c) is the point number indicating the current location of the point where the board is installed, and in the case of a destination board, the destination. The location number should also be indicated. Alternatively, it may be a destination display board as shown in FIG. 5(a), or it may be a board displaying only the point number of the current location as shown in ([)). Using this method, the previous example would become as follows.

Here, the map of the area shown in the gi diagram is marked with the claims (here, it is assumed to be 123, and the part of city B is 124), and the scale and (the faded third
Assume that you have the map shown in the figure. A car traveling east on the national highway found the destination information board shown in Figure 4 (a) at the intersection (a). At the bottom of the sign board, the point number 123-60-65 indicating the current location of the intersection is shown, and the point number +23-22J is also written at the bottom of the destination C city.
If you look at points 60 on the horizontal scale and 65 on the vertical scale on the map with area number 123 shown in Figure 3, you will see that your current location is at the intersection (A), and if you turn left you will enter the R local road that leads to City C. This can be confirmed, and the location of City C can be easily found in the same way.

If you continue north on R local road and find the place name board shown in Figure 3 (exit), even if the place name is not on the map,
From the number 123-511i-44, you can accurately determine whether you are currently running at the point on the map.
If you know the point number of the destination A town, you can easily find its location on the map, and the road to get there is to turn right at the intersection (c) with point number +23-51-28. I understand. Then, by finding the destination information board in Figure 4 (C), even if you don't know about City B,
By looking at the number displayed on the current location, you can confirm that this is the point where you should turn right. Also, even if you are looking for City B just to be sure, you can quickly find out where it is on the next page from the point number written on the guide board. As can be seen in this example, if such signs are arranged and the point number of the destination is known, there is no need to know the names of places along the way. In other words, even if you are a foreigner who cannot read any kanji, you can easily and accurately reach your destination using the same road map designed for Japanese people, even if there is no romanization. In this way, road signs that use the universal numeric point display system are more suitable for the age of internationalization than those that use Roman letters.

Furthermore, the convenience of this method is that, as mentioned earlier, if
If you make a chart like Figures 6 and 7, assuming that each cell is a 500m square, you can simply calculate the distance between two points whose point numbers are known. In other words, find the difference in the horizontal scale and the difference in the vertical scale between the two points, apply them to Figure 6 or Figure 7, and look at the intersection.The former is a number, and the latter is easy to see on the diagram. The distance is required. This distance is of course a straight line distance, not an actual distance. However, compared to conventional road maps, where you add up the distances for each section, and find the midpoint between sections by eye, it is much easier to find the approximate distance. Note that when calculating distances between other regions, it is troublesome if adjacent maps are misaligned. For this reason, conventional road maps often divide the country into regions in a houndstooth grid pattern according to the topography, but in this case, it is preferable to divide the country in a regular grid pattern rather than in an arbitrary manner.

Another advantage of this method is that you can find the direction by knowing the increase or decrease of the numbers. In other words, if the number increases in the horizontal direction, the direction is east, and if the number increases in the vertical direction, the direction is south. In other words, you can easily tell which direction you should go based on the difference between the numbers between your current location and your destination location, and even when you are driving at night and don't know where you are going or in what direction, you can easily tell the direction you should go from one location sign to the next. You can easily tell which road and direction you are heading by looking at the changes in the numbers up to the point sign.

As mentioned above, by using the method set forth in claim 2, if the vertical product is further divided into ten equal parts and each point is represented by a 3-digit number, gt9-digit number, a small area such as 5 o 11 corners can be specified. I can do it. This means that it can also be used to display the location of private houses. Of course, if it is 50m square, several houses will use the same number, but it has sufficient practical value.

This system will be adopted for road signs across the country, and this point number will also be written on place name display boards installed at intersections, town name display boards and telephone poles at each crossroads, etc. As you can see from the previous explanation, it is extremely easy to find the house you are looking for even if you do not have a map. All households now use their home location number as part of the address display, and if the location number is listed along with the address of the destination, not only courier services and department store deliveries, but also postal deliveries. It will be very convenient. In the past, a map of the area was often used, but in the future it will be easier and more reliable to search by adding the location number to the map. This 9-digit number may seem very long, but it is by no means long considering that telephone numbers, including the area code, use 10 digits.

In this way, if you simply want to know your current location, if the above-mentioned signs are in place, you will not need to use a complicated navigation system. However, if this point display method is used, it is possible to more easily realize a navigation system that is inexpensive and has high utility value that anyone can obtain.

As shown in claim 5, suppose that a transmitter that continuously transmits the number 1236065 or a coded version thereof is installed at a certain point, for example, the point (a) in Fig. 3. . Then, a car carrying the receiver set forth in claim 7 and traveling east on National Route N will (a) display the display device installed in the driver's seat when it comes within the range of the radio waves of the transmitter at the location; 123-80-65 is displayed.

Drivers who see this will know in advance that the point (a) is nearby, and will not miss the sign shown in Figure 4 (a).Such transmitters are installed on major arterial roads, key points in urban areas, etc. Once it becomes popular on a nationwide scale, you will be able to easily check your current location at any time, no matter where you go in the country, as long as you have a reception desk and a map. The transmitter frequency must be able to be received anywhere in the country with the same receiver, so transmitters installed anywhere in the country must have the same frequency. Seven digits is considered to be sufficient for practical purposes, but it would be effective to set it to nine digits (in urban areas, etc.).

Furthermore, as shown in claim 6, for example, FM
By transmitting on two channels, one side can transmit the point number of the location where the transmitter is installed, and the other side can be operated when necessary to send another point number and a backup code of one or more digits. It becomes an effective road information system. To give an example, suppose that an accident occurs at a point P in the eastbound lane of a road running east-west as shown in FIG. 8, and congestion in the eastbound lane is expected. At this time, operate the transmitter (■■■ in the diagram) up to a certain range west of the 2 points, and select the transmitter! Along with the point number of the 2nd place, the point number of the P point and the preliminary code can be sent (The contents of this preliminary code are as follows.
For example, it is predetermined that 1 is an accident, 2 is an accident being handled, 3 is under construction, 4 is a natural traffic jam, etc., and in this example, a code of 1 is transmitted. Suppose that a car traveling east on this road hits a traffic jam at point 9, a few kilometers before point P. In the past, drivers would have had no idea what was causing this traffic jam or why it was continuing for such a long time. However, in the case where the aircraft is equipped with 248 aircraft as described in claim 8, the signal emitted from the three points near point Q will immediately tell you your location, the location of the accident site, and the cause of the traffic jam. This is understandable. Then, depending on the situation, it can be determined that it is better to take a detour. Also, this road is an expressway, etc., and the P point is not an accident, but there is a rest stop there, and I have decided on the number of the rest stop with the backup code, and usually I issue that code at the point ■■■. If you keep this in mind, you can easily find out in advance where the rest area is and how far it is from the explanation given earlier. Each transmitter may be operated directly, or by wired or wireless instructions.It is possible only with the method of the present invention to be able to transmit and receive road information at other points in addition to the current location. The satellite method cannot be imitated by any other method. It is thought that many of these receivers are used as car-mounted receivers as shown in claim 9, but there is a receiver that receives radio waves of a specific frequency and displays a 7-digit or 9-digit number on a liquid crystal display. Since the receiver can be made extremely compact, it is possible to make a portable receiver as described in claim 10. Then, if you put it in your pocket when you go on a trip, you can easily find out where you are. In such cases, it would be convenient if the transmitter could be installed not only on roads, but also at tourist spots, for example.

Tourist buses these days rarely provide tourist information, and it is common for passengers to have no idea where they are traveling until they reach their destination. Therefore, as described in claim 11, a receiver is installed on the bus.
Place the display in a conspicuous place, and hand out route maps with point scales that include point numbers and tourist information for sightseeing spots that can be seen outside the window, so that passengers can always know their current location. This is an excellent service as you can get to know more about the scenery and get more interested in seeing the scenery outside. Such services are also possible on long-distance railways.

Moreover, when applied to navigation systems, even better systems will become possible. That is, as described in claim 12, a map created by the area division method described in claim 1 is recorded in advance on an image recording device, and the map as described in claim 5 or 6 is By receiving the signal of the current location emitted from the transmitter mentioned in the section, the corresponding map is automatically searched from the area number and displayed on the CRT screen. A display device that can display your current location can be created by making the corresponding part emit light, emit color, or blink. In addition, the signal from the transmitter described in claim 6 is received, and information on the accident location and its cause is displayed on the screen, as described in claim 8. Scope of patent claims @13
You can display HR for the staff. In this case, the distance between point P and point Q can be calculated and displayed on a part of the screen. According to such a navigation system, the display points automatically change as the car moves, and the map also changes automatically even when the area changes. Therefore, there is no need to go through an atlas to find a map of the area based on a place name that you have never asked before, or to find out which point in the map, and it is displayed immediately on the CRT. Therefore, it is incomparable to the conventional method of having an atlas in hand. It would be even more convenient if the map of another area could be displayed by blinking or by inputting the area code.Furthermore, as described in claim 14, If a device is installed in the vehicle that records the point number received at a certain time on an IC card along with the time, it can be used as a vehicle operation record.This device can be used with #9 to record the point number received at a certain time, for example, along with the cumulative distance, etc. Record it on an IC card and read it on your phone at the end of the day.This will allow you to check the day's driving route and operation status, which previously had to be checked.

As a result, records are kept in a very organized manner, making it possible to perform statistical processing and obtain valid data that could not be obtained in the past.It also provides valuable data as labor management materials for drivers. Ru.

This application is very effective in places where vehicle management is required, such as taxis, buses, various patrol cars, and trunks for transportation.

It is desired to monitor all of a large number of vehicles, such as patrol cars and taxis, simultaneously in real time and to understand their current locations. Therefore, as described in claim 15, each vehicle receives the completed signal from the transmitter described in claim 5 or 6, and the received point number is sent to the vehicle. Equipped with a transmitter that can send vehicle numbers, especially in the case of taxis, signals indicating whether the vehicle is real or empty, receives these signals sent from each vehicle at once, and automatically calculates the location number from the received point number. In general, being able to display the location of all vehicles on one display provides a system that allows the entire army to be monitored at a glance.

The disadvantage of this method is that it receives the point number directly from a single transmitting station, rather than receiving and calculating multiple radio waves like the artificial double layer method or Lorand method, so the range of radio waves is limited. The wider the area, the wider the range of a certain point, and the worse the position accuracy becomes. Therefore, in order for such a system to be effective, it is desirable to install as many transmitters with short radio wave reach as possible, for example, at each major intersection. So, for example, if we were to install these transmitters at one location per square kilometer in the entire area of central Osaka (212 km), a total of 212 transmitters would be required, but the required reach distance for 11 waves is 500 m. Well,
Since the output of this transmitter is still smaller than that of a transceiver, the unit cost per unit is very small and the total cost is not very large. In reality, it can be said that this level of positional accuracy is sufficiently practical for the positional accuracy required by the general public.
