JPH06243396A - Parking lot admission wait time display device - Google Patents

Abstract

PURPOSE:To display a wait time in real time by finding the weighted mean of admission time intervals of a prescribed number of vehicles, and displaying the admission wait time by the output of a weighted mean means. CONSTITUTION:Once a vehicle entering a parking lot is sensed at an entry gate, a wait time calculating means 2 inputs the time by vehicle admission information from the entry gate, finds the time difference with the entry time of a preceding vehicle to obtain a time interval, and also calculates the weight mean of time intervals of a prescribed number of vehicles. Then when an admission waiting queue at the entry gate exceeds prescribed length, a vehicle sensor at a prescribed position from the entry gate senses the vehicles which stop for longer than prescribed time. A feature quantity extracting means 1 which receives the sensor output lets a wait time display device 3 operate to display the time interval which is the weighted mean on the wait time display device 3 as a current admission interval for users near the entrance.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically calculating and displaying waiting time at a parking lot entrance.

[0002]

2. Description of the Related Art Conventionally, a parking clerk determines a rough waiting time based on his experience and manually inputs it to a display device, and a device for automatically calculating and displaying the waiting time has not been realized. Absent.

[0003]

As described above, there are problems such as inaccuracy in determining the waiting time based on the experience of the staff, and difficulty in deciding the rewriting timing of display contents and real-timeness in the manual input. is doing. Also, even if time determination and display are automated, each parking lot or date,
There is also a problem that the waiting time depends on various conditions such as the day of the week and the time of day.

The present invention has been made to solve such a problem, and an object thereof is to obtain an apparatus for calculating a waiting time in real time and displaying the waiting time.

[0005]

A parking lot entrance waiting time display device according to the present invention is for displaying to a customer waiting for entry at the entrance of a parking lot, and is provided for a predetermined number of vehicles. A waiting time calculating means for obtaining a weighted average of the entrance time intervals and a display device for displaying the entrance waiting time by the output of the weighted averaging means are provided.

[0006]

The waiting time calculating means calculates the entrance intervals of a predetermined number of vehicles and takes the average thereof. By taking the weighted average of recent time intervals, it is possible to significantly affect the recent waiting time. This average value is displayed on the display device as the current waiting time.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of a waiting time display device according to the present invention. FIG. 2 is a flow chart for explaining the operation of this device. In FIG. 1, 1 is the number of entrances and exits sent from each device such as each entrance / exit gate in the parking lot, vehicle detection sensor, and the presence / absence of vehicles at each parking position, or the parking amount at each current date, day of the week, and time. Change amount, feature amount extraction means for extracting feature amounts such as surrounding traffic conditions, and 2 are waiting time calculation means for obtaining a weighted average of entry time intervals of a predetermined number of vehicles based on entry / exit information sent from the entry / exit gate. Is a waiting time display device for displaying the time obtained by the waiting time calculation means 2 in the queue of the vehicle from the entrance of the parking lot.

When a vehicle entering the parking lot is detected by an entrance gate (not shown), the waiting time calculating means 2 inputs the time based on the entry information from the entrance gate,
The time difference from the entry time of the preceding vehicle is obtained to obtain the time interval, and the weighted average of the time intervals of a predetermined number of vehicles (for example, about 10 vehicles) is calculated. At this time, the weight is increased for each time interval that is more recent, and the time interval closer to the current situation is calculated.

When a line waiting for entry at the entrance gate is formed and the line is connected for a predetermined length or longer, a vehicle detector (not shown) located at a predetermined position from the entrance gate is stopped for a predetermined time or longer. To sense. In response to this, the feature amount extraction means 1 operates the waiting time display device 3 and displays the weighted average time interval described above as the current entrance interval on the waiting time display device 3 to the users near the entrance. .

When there is a parking space and there is no queue for entry, there is no vehicle that has stopped at the predetermined position for a predetermined time or longer, so even if the waiting time calculation means 2 calculates the weighted average. The feature amount extraction means 1 does not display this average value on the waiting time display device 3 but displays other guidance information.

[0011]

According to the parking lot entrance waiting time display device of the present invention, the waiting time can be displayed in real time because the entrance intervals at the entrances in the parking lot are averaged.

Since the current data in the parking lot is used regardless of the experience of the staff, the waiting time can be displayed without being influenced by various conditions such as the day of the week and the time, and the entrance gate can be displayed at several places. Even if it is set, the waiting time is calculated only from the entrance interval of the entrance gate, so that the waiting time can be calculated without being influenced by the conditions of other entrance gates.
