FIG. 1B is a graph showing the X, Y, and Z points in FIG. 1A, that is, the passing traffic before the intersection A, before the intersection Y, and before the parking lot P. The point indicates that the number of vehicles turning right or left at intersection A is greater than the number of vehicles entering intersection A. Further, at the point Z, the number of vehicles turning right or left at the intersection B is smaller than the number of vehicles entering the intersection B. The graph shown by the solid line Z in FIG. 3 shows the daily change in the passing traffic volume at this Z point (Step 100 in FIG. 4; the steps are hereinafter referred to as “S”). The measurement of the passing traffic volume at each point is performed based on a detection signal when a car (not shown) has passed the road R by a sensor such as a known ultrasonic sensor or an optical sensor. The detection signal from each point is transmitted to the center device 1 via a communication line (not shown), and the center device 1 measures the passing traffic volume at each point, or information on the passing traffic volume measured at each point. (Data) is transmitted to the center device 1 via the communication line.
[0014]
FIG. 1C is an entry / exit pattern (entrance / exit distribution) (T) showing the entry state and exit state in the parking lot P over time. Here, for simplicity of explanation, the parking lot P is shown as capable of parking 12 vehicles. The entry / exit pattern (T) shown in FIG. 1 (c) is initially (early time) flat when 12 cars are parked, and gradually decreases at late time. Present. The entry of a car into the parking lot P and the exit of a car from the parking lot P are detected using a known ultrasonic or optical sensor. Then, the detected signal (including the detection signal of the current number of parked vehicles in the parking lot P) is configured to be transmitted to the center device 1 via a communication line (not shown) (S100b in FIG. 4). .
[0015]
Note that the above-mentioned entrance / exit pattern (T) is an entrance / exit pattern of only the parking lot P, but may be an entrance / exit pattern of a plurality of parking lots in a predetermined area. For example, a wide-area parking lot including a plurality of parking lots around the station that can be used by the P & R system may be used. In this case, the guidance of the parking lot of the P & R system can be effectively performed in a wide range.
[0016]
FIG. 3 compares the state of the passing traffic volume (Z) per day at the Z point in front of the parking lot P with the entrance / exit pattern (T) indicating the increase / decrease state of the number of parked vehicles per day in the parking lot P. ((Z) / (T)) is a graph shown together for easy study (S102 in FIG. 4). As a matter of course, the graph shown in FIG. 3 shows various modes depending on the day of the week, the beginning of the month, the end of the month, and the like. Therefore, the value considered by the above-mentioned comparison ((Z) / (T)) is based on past data such as the previous day, the previous week, the previous month, the previous year, and all other conditions such as climatic conditions in the same period in the past. Learning using the past data obtained is performed in the center device 1 (S104).
[0017]
As a result of the learning described above, suppose that the graph shown in FIG. 3 is obtained as the passing traffic volume (Z) and the entrance / exit pattern (T) of the day (S106 in FIG. 4). The contents to be displayed are determined and displayed on the display boards 2a, 2b, 2c installed at the X point, the Y point, and the Z point of 1 (a) (S108 in FIG. 4). That is, when the passing traffic volume (Z) at the Z point in front of the parking lot P is indicated by a solid line in FIG. 3, the entry / exit pattern (T) of the parking lot P is indicated by a chain line (T) in FIG. 11:00, it is predicted that 12 cars will be full. Therefore, for example, when the parking rate of the parking lot P reaches 90% (11 vehicles) (in the example of FIG. 3, the display panel 2c depends on the distance from the display panel 2c to the parking lot P). At about 10:30), it is displayed that the vehicle is full. Similarly, depending on the distance between the display boards 2a and 2b and the parking lot P, for example, the display board 2a indicates when the parking rate of the parking lot P becomes 50% (six) (9 in the example of FIG. 3). At about 30:30), it is displayed that the car is full, and the display board 2b indicates that the parking rate of the parking lot P has reached 70% (eight cars) (about 10:00 in the example of FIG. 3). A message that the vehicle is full is displayed. Each of the display boards 2a, 2b, and 2c indicating that the vehicle is full is reduced by a predetermined rate (for example, 20%) from the above-described parking rate (in the case of a 20% reduction, 70%, 50%, and 30%). A message indicating that the vehicle can be parked in the parking lot P, that is, an empty vehicle is displayed (S110 in FIG. 4).
