Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to information guidance technology for the movement of people using transportation means such as cars and buses, and belongs to ITS (Intelligent Transport Systems) technology.

[0002]

2. Description of the Related Art Traffic jam information is important information when driving a car or the like, and its demand is high, and information has been conventionally acquired. The first implementation was for expressways. On a highway, a beacon is installed on the road at regular intervals, the speed of a car traveling under the beacon is automatically detected, and whether or not congestion is occurring is checked based on the speed. The same has been done on some highways other than highways. The searched traffic jam information is presented to the driver in various ways, such as displaying it on a traffic information board installed along the road, displaying it in a parking area, broadcasting it on the radio, displaying it on a car navigation system, etc. I was

[0003]

[0005] While traffic jam information is important information for drivers, as described in the above-mentioned prior art, only a very small range of roads nationwide, such as expressways and some highways, is used. It is not currently targeted. However, even on other non-public roads, traffic information is very important in the lives of the general public. Examples are given below.

[0004] Case 1: A road that should not always be crowded is crowded and a car does not travel. Where is crowded and how long will it be until xx? I'm worried that I'll be on time for the promise. If it is faster to avoid the congestion and do the detour, I would like to do so, but in that case, what route should I take? If you don't choose an appropriate route, it may take longer.

[0005] Case 2: I want to go to the station by bus, so I wait at the bus stop, but the road is crowded and the bus does not come at all.
I don't want to walk to the station because it takes about 40 minutes, but the time for an appointment to the customer is approaching. Hesitates whether to walk or wait for the bus. It would be helpful to know the current location of the bus and how long it will take you to the station if you use the bus.

On a general road, there are left and right turns and intersections as compared with an expressway, so it is necessary to grasp traffic congestion information more finely.

(First Embodiment) A traffic information guidance system according to a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram of the traffic information guidance system according to the first embodiment, and FIG. 2 is a flowchart illustrating the operation of the traffic information guidance system according to the first embodiment.

As shown in FIG. 1, this traffic information guidance system is installed near a road intersection 1

Traffic information service center 14 to deliver to
And a communication network 15 connecting them are main components. The imaging device 11 is installed at each intersection. In an urban area, the traffic may be at each intersection where there is a traffic light. However, in an area where traffic light is low, it is preferable to install the imaging device 11 at several intersections between traffic intersections.

The traffic congestion information service center 14 obtains image data obtained by the imaging device 11 and the artificial satellite 12 installed at various places via the communication network 15, and the image data obtaining unit 21 obtains the image data. Image recognition processing unit 22 that performs image recognition processing on the processed image data, a traffic jam situation analysis unit 23 that analyzes a traffic jam situation based on the image recognition processed data, A traffic jam information database 24 that stores the traffic jam information analyzed in 23 and a traffic jam information distribution unit 25 that distributes the traffic jam information to the information terminal 13 via the communication network 15 are provided.

The communication network 15 may be any one that can connect and communicate with terminals and the like, such as wireless communication, mobile communication, CATV, optical fiber, the Internet, satellite communication, and other wired communication.

Next, the operation of the traffic guidance system according to the present embodiment will be described with reference to FIGS. First, in the imaging process (step S1), the road intersection 1 is captured using the imaging device 11 or the artificial satellite 12 having an imaging function.
To shoot. The data to be photographed may be a still image or a moving image. In addition, there is a method of taking a picture at regular intervals such as every minute, every 10 minutes, every hour, or the like. In a region where traffic congestion rarely occurs, such as in a local region, a photograph may be taken when there is a traffic congestion information distribution request from a user. Furthermore, when using the artificial satellite 12,
There is also a method of photographing each intersection using the position information of the intersection 1 or a method of photographing a wide area including a plurality of intersections 1 and cutting out necessary image data from the intersection position information.

Each imaging device 11 stores the ID information of the intersection 1 in order to distinguish itself from other imaging devices 11, and transfers the ID information together. When the artificial satellite 12 is used, the ID information of the taken intersection 1 is transferred. When a wide area covering a plurality of intersections 1 is imaged, a plurality of intersection IDs are transferred.

Vehicle speed recognition, traffic volume prediction, and the like are performed, traffic jam information is calculated, and stored in the traffic jam information database 24. The calculation is performed by comparing still images and moving images shot at fixed time intervals with stored recognition results. For example,
A plurality of recognition results are collated, and if the shape, color, position, and the like of the vehicle have not changed, or if they have changed, but are about several meters, it indicates that the traffic flow has deteriorated during that time. Further, if the time is 5 minutes or more, it can be understood that traffic congestion is occurring at the place. Also, if you have a road information database that stores the connection relationships of intersections,
By using the information and tracing the congested intersection ID, it is possible to identify the location causing the traffic congestion and the traffic congestion when traveling along which road and in which direction.
