  According to the present invention, it is possible to generate accurate traffic congestion information without resorting to manual labor.

It is a figure which shows the traffic congestion information system of embodiment which concerns on this invention. In an embodiment concerning the present invention, it is a figure showing a relation between a running vehicle and a vehicle running ahead of the running vehicle.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following, similar elements are denoted by the same reference symbols in all the drawings, and redundant description will be omitted. Further, in the description in the text, the reference numerals described before are used as necessary.

  FIG. 1 is a diagram showing a traffic congestion information system 10 according to an embodiment of the present invention. FIG. 2 is a diagram showing a relationship between a traveling vehicle 8 and a vehicle 8 traveling in front of the traveling vehicle 8 in the traffic congestion information system 10 according to the embodiment of the present invention.

  The traffic jam information system 10 is a system that provides information about traffic jams on general roads and highways. The traffic jam information system 10 includes an information acquisition / generation unit 12 that is connected to a vehicle 8 traveling on a general road, an expressway, or the like via the network 2.

  The network 2 is a communication technology capable of realizing high speed and large capacity, connection of a large number of terminals, ultra low latency, and ultra high reliability in the IoT era (Internet of Things) where various things are connected to the Internet, for example, the fifth generation. It is composed of a mobile communication system (so-called 5G).

  The information acquisition / generation unit 12 includes a position information acquisition unit 14, an inter-vehicle distance acquisition unit 16, a speed acquisition unit 18, an average calculation unit 20, a traffic jam information generation unit 24, and a dynamic price setting unit 26.

  The vehicle 8 includes a position information sensor unit 29, a distance sensor unit 30, and a speed sensor unit 31. The position information sensor unit 29 receives radio waves from a plurality of GPS satellites managed by the U.S. Department of Defense and calculates the distance to each GPS satellite to determine the current position of the vehicle 8.

  The distance sensor unit 30 measures the inter-vehicle distance between the vehicle 8 traveling on the road and the vehicle 8 traveling in front of the vehicle 8. As an example of the distance sensor unit 30, for example, an optical camera sensor can be used.

  Since the optical camera sensor can digitize the information displayed by the camera, it can recognize not only the vehicle but also the white line on the road. Further, the optical camera sensor can recognize the brake lamp of the vehicle 8 in front of which the image is colorized and which is lit in red.

  Alternatively, a stereo camera having two optical cameras arranged side by side may be adopted. Since the stereo camera enables the same binocular stereoscopic vision as a human, it can grasp an object in three dimensions, and enables finer control than a monocular camera equipped with only one optical camera.

  As described above, the distance sensor unit 30 has been described with respect to an example using a camera, but of course, it may be measured by another method, for example, by a millimeter wave radar mounted on the tip of the vehicle 8 or a grill part. The distance to the vehicle 8 running ahead may be measured.

  The characteristics of the sensor using the millimeter-wave radar are that it is not easily affected by bad weather such as rain or fog or at night, and in addition to the information on the distance, relative speed, and angle with the vehicle 8 traveling ahead, The point is that it is possible to instantly recognize a change such as whether the own vehicle is approaching or far from the vehicle.

  The speed sensor unit 31 includes a sensor provided on the axle of the tire of the vehicle 8 for measuring the number of revolutions, and a display unit for converting the number of revolutions obtained from the sensor into a velocity and displaying the velocity.

  Although there are a plurality of methods for measuring the number of rotations of a tire, a method using a magnetic sensor will be described here. The magnet is attached to the spokes of the wheel, and the sensor is attached to a position where the magnet passes on the forks that sandwich the wheel.

  The sensor is provided with a device called a "Hall element" that produces a signal when the magnet passes by. The sensor generates a signal each time the wheel rotates and the magnet passes near the sensor.The vehicle speed is calculated from the number of times this signal is generated in a certain time and the outer circumference of the tire, and it is displayed on the speedometer. There is.

  The position information acquisition unit 14 has a function of acquiring the position information of each vehicle 8 transmitted from the position information sensor units 29 of the plurality of vehicles 8 connected via the network 2. The timing of transmission from the position information sensor unit 29 of the vehicle 8 can be set to a predetermined period, for example, 60 seconds.

  The inter-vehicle distance acquisition unit 16 acquires the inter-vehicle distance between each vehicle 8 transmitted from the plurality of distance sensor units 30 connected via the network 2 and the vehicle 8 traveling in front of the vehicle 8. It has a function. The timing of transmission from the inter-vehicle distance acquisition unit 16 of the vehicle 8 can be set to a predetermined period, for example, 60 seconds.

  The speed acquisition unit 18 has a function of acquiring speed information of each vehicle 8 transmitted from the speed sensor units 31 of the plurality of vehicles 8 connected via the network 2. The transmission timing from the speed acquisition unit 18 of the vehicle 8 can be set to a predetermined period, for example, 60 seconds.

  The average calculating unit 20 has a function of calculating the average of the inter-vehicle distances acquired by the inter-vehicle distance acquiring unit 16 and the traveling speed acquired by the speed acquiring unit 18 for each vehicle 8 within a predetermined period.

  Here, the “predetermined period” can be set to 60 seconds, for example. If it is a relatively short period of 5 seconds or 10 seconds, for example, it may be mistaken for a state of being almost stopped while parking at a parking lot such as a shopping center, but if it is 60 seconds. This is because it is considered to cover the time required to complete parking after entering the parking state.

  By being transmitted from the position information sensor unit 29, the distance sensor unit 30, and the speed sensor unit 31 every 60 seconds, unnecessary data can be reduced and the above-mentioned erroneous recognition can be prevented.

  The traffic jam information generating unit 24 associates the position information of each vehicle 8 with each inter-vehicle distance and each traveling speed calculated by the average calculating unit 20 at predetermined intervals (for example, every 60 seconds) to obtain a plurality of them. It has a function of generating congestion information based on collective intelligence obtained from the following distance, traveling speed, and position information.

  When the average inter-vehicle distance calculated by the average calculator 20 is, for example, 2 m and the average speed is, for example, 15 m / h in a predetermined area, congestion occurs at the position of the corresponding group of vehicles 8 (a predetermined area). It can be determined that there is a possibility that

  The network 2 is composed of a communication technology capable of realizing high speed and large capacity, connection of a large number of terminals, ultra low delay, and ultra high reliability, for example, a fifth generation mobile communication system (so-called 5G). The innumerable position information sensor unit 29, the distance sensor unit 30, and the speed sensor unit 31 of the vehicle 8 can be connected.

  As a result, it is possible to generate more reliable traffic jam information by the collective intelligence obtained from the countless vehicles 8.

  The dynamic price setting unit 26 can change the service usage price based on the traffic congestion information generated by the traffic congestion information generating unit 24. Generally, a parking lot (parking) or a highway has a fixed charge, but the cost may be dynamically changed depending on the congestion due to congestion.

  For example, in a temporarily used parking lot that is temporarily used, a high parking fee is set when the number of parked vehicles 8 is large, and a parking fee is set when the number of parked vehicles 8 is low. The price may be set low and the parking fee may be changed according to the congestion level.

  Also, when using the expressway, for example, the Meishin Expressway from Osaka (Suita) to Shiga (Otsu), when there is congestion near Kyoto (Kyoto South), depending on the distance and time of the congestion, The cost may be set lower than when there is no traffic.

  Next, the operation of the traffic jam information system 10 having the above configuration will be described. Conventionally, the traffic congestion occurrence situation on general roads and highways is generated by a traffic volume surveyor while visually confirming the traffic congestion situation. Therefore, there is a problem that it is not possible to create accurate traffic congestion information for a place where the traffic information inspector does not wait.

  However, according to the traffic jam information system 10, a communication technology capable of realizing high speed / large capacity, connection of a large number of terminals, ultra low delay, and ultra high reliability, for example, a fifth generation mobile communication system (so-called 5G) is used. The traffic jam information is generated based on the information obtained from the position information sensor unit 29, the distance sensor unit 30, and the speed sensor unit 31 of the countless vehicles 8 connected to the network 2. Therefore, since the traffic congestion information can be obtained by the collective intelligence obtained from the innumerable data, it is possible to obtain the traffic congestion information with higher reliability.

  Further, according to the traffic congestion information system 10, since the position information, the inter-vehicle distance information, and the speed information of the vehicle 8 are not always transmitted (acquired) but are transmitted (acquired) every 60 seconds, unnecessary information Transmission (acquisition) can be reduced.

  Further, as described above, if the interval is 60 seconds, for example, the risk of erroneously recognizing the time zone parked in the parking lot as a traffic jam can be suppressed, and thus more accurate traffic jam information can be transmitted to the user or the like. There is an advantage that you can.

  Further, according to the traffic congestion information system 10, since it is possible to change the fee for the expressway and the fee for using the parking (parking lot) based on the traffic congestion, it is possible to connect to the user's sense of fairness. It has the effect of reducing traffic congestion.
