Description

[Detailed Description of the Invention] [Summary] The traffic situation or the presence situation of vehicles such as cars on roads such as intersections is detected by a monitoring device such as a television camera or infrared sensor, and the screen obtained by this or this The screen is constructed by superimposing the screen on a road map or other drawing of the intersection as required, and then broadcast on television, and the image is received by a television receiver installed in a car to monitor road congestion. We made it possible to know such things while in the car.

[Industrial Application Field] This is a system that allows people in a car to select a route that is appropriate for the congestion situation by understanding the road traffic conditions related to their future route on the screen. be.

[Prior Art] Conventionally, people listen to the road conditions inside a car from radio broadcasts, etc., and choose a route to avoid congested roads.

[Problems to be solved by the invention] However, when radio broadcasting is used in this way, information is only obtained by hearing, so it is difficult to accurately grasp the traffic situation, and it is difficult to understand the traffic situation by yourself. In reality, it is impossible for the course situation required by the applicant to be constantly broadcast.

The present invention eliminates these drawbacks and provides a traffic information service system that allows drivers to visually confirm what kind of traffic situation their own vehicle is in.

[Structure and operation of the invention] Fig. 1 is for explaining the principle of the traffic information service system of the present invention.
A monitoring device S such as a television camera is installed at a position where it can photograph the image, and the obtained image V is transmitted to a center indicated as a regional center C via a communication line.

This regional center receives images similar to those described above from monitoring devices installed at multiple monitoring points within the area it is in charge of, and also directly or pre-images the images from these monitoring devices. A broadcast screen is created by superimposing the above image V on a road map or other drawing of the monitoring area prepared at the center as a map or pattern, and the monitoring area in the area to be broadcast and the screen to be broadcast are created. The selected program is then transmitted as a television broadcast by broadcasting equipment illustrated as a separately provided broadcasting station T in this figure.

The monitoring device may further include a detection device for detecting data such as vehicle traffic volume, such as an infrared tracking device and a passing vehicle sensor, and the data obtained by the detection device is sent to the center along with images via the communication line. This center can also generate road information based on the images and data and transmit it as a television screen or as audio information accompanying this screen as a television broadcast.

In addition, in this broadcasting, the name of the intersection in the image being broadcast, the traffic situation obtained from the traffic volume data d, etc. can be broadcast as audio information simultaneously with the above screen using voice or synthesized voice.

Additionally, this center may transmit the place name of the monitored location superimposed on the broadcast screen so that the displayed monitored location can be viewed together with the road conditions. It would be even more convenient to write the place name, town name, building name, etc. on the image of the intersection, or to indicate the installation positions of traffic lights, fire hydrants, public telephones, etc.

Furthermore, the above-mentioned centers 〇 are set up in each region, and as shown by the dotted lines in Figure 1, a wide-area center CW is set up to centrally receive the above-mentioned images and data from these regional centers. By collectively processing traffic information for a wide area covered by
It is also possible to carry out traffic control over a wide area, and at the same time, it is possible to broadcast traffic information over a wide area on television.

Furthermore, by installing a receiver near the road to receive the traffic information broadcast as described above, it is possible to make this traffic information available even to drivers of automobiles that are not equipped with a receiver. Can be done.

[Embodiment 2] FIG. 2 is an embodiment showing an example of the arrangement of monitoring devices provided in the vicinity of an intersection, which is an example of a monitoring location where traffic conditions are to be detected according to the present invention.

The outer wall of the building 10 or the roof of the building 20 near the intersection that is the monitoring point, the telephone pole or traffic light pole 30 or the telephone box 4 installed near the intersection.
0 and other intersections and the road leading to the intersection, there will be a television camera to obtain a screen containing images of vehicles, as well as an infrared tracking device and passing vehicle sensor to detect data such as traffic volume as required. Monitoring devices 11, 21, 31, and 41 including detection means are arranged, and images of the intersection including images of vehicles detected by these monitoring devices and traffic conditions such as traffic volume data are recorded as shown in Figure 1. As explained above, the information is sent to the center via a wired or wireless communication line.

In Fig. 2, the dotted line shows an example of the field of view that is the monitoring range of the television camera of each monitoring device, and in each case, the television camera is installed with emphasis on photographing the vehicle from the front and upper side. .

The monitoring device 11 installed on the outer wall of the building 10 has the advantage that it does not occupy the roof of the building and there are no structural elements of the building to get in the way, allowing a good field of view. The monitoring device 21 is easy to install, and since both of these devices can provide a screen from a relatively high position, by placing signs such as letters and symbols on the roof of the vehicle, it is possible for the driver etc. This has the effect that the user can check the vehicle he or she is driving on the screen.

Further, it is preferable that the television camera 31 installed on the traffic light pillar 30 has its upper part bent and protrudes above the roadway as shown in the figure. It is clear that the same effect can be obtained not only when installed on a traffic light pole but also on a street light having a similar shape.

The monitoring device 41 installed on the telephone booth 40 has the advantage that it is not only easy to install, but also that the field of view is not obstructed because the telephone booth is generally installed adjacent to the road. It can be similarly installed at subway entrances and exits.

As mentioned in Figure 1, Center 〇 receives the above-mentioned images and traffic data from a large number of monitoring points in each applicable area, and also transmits information on each intersection as a television signal to that area. And this intersection R
The image of the intersection received from is used as a broadcast screen,
Alternatively, a broadcast screen is created in which an image of the vehicle obtained from the image of the intersection is superimposed on a drawing of the intersection prepared in advance as a map or pattern.

Then, each intersection in the area is selected, and these screens are also selected and transmitted as a television broadcast from the television broadcasting equipment installed at this center or other broadcasting equipment such as a broadcasting station.

[Effects of the Invention] According to the present invention, since the screen photographed at the monitoring point is broadcast on TV via the center, when a traffic accident occurs, the occurrence of the accident, its circumstances, and the injured persons are monitored. This center can immediately grasp the status of accidents and quickly and accurately take measures to deal with accidents or respond to emergency activities, thereby preventing the spread of accidents and the loss of human life.

In addition, since the screen shot at the monitoring point will be broadcast on TV, the driver or owner of the vehicle can display the location of their own troops by placing appropriate signs such as letters and symbols on the roof of the vehicle. Since you can check the above, it is easy to predict the required time, and you can easily select whether or not to take a detour or select a detour.

According to the present invention, by installing a television receiver in not only general drivers but also emergency vehicles such as police, fire, and emergency vehicles, and business vehicles such as taxis, buyers, and transportation companies, A special effect can be achieved in that the time required to reach the required location can be significantly shortened.
