Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for monitoring the operation status of a car traveling on a toll road such as a highway, and more particularly, to calculating an accurate average speed of a car traveling on a highway. The present invention relates to a road operation status monitoring system capable of obtaining accurate operation information.

2. Description of the Related Art Conventionally, when a car enters a highway from a general road, a driver first specifies information such as an entrance gate name and a gate number at an entrance gate of the highway, The driver passes a toll ticket on which predetermined information such as the time when he / she entered the entrance gate is recorded.

[0003] Then, at the exit gate provided at the place where the user arrives at the destination and exits the expressway to the general road,
By giving the toll ticket to the attendant, the toll is calculated by the toll adjusting machine based on the information stored in the toll ticket, and a predetermined toll is paid to perform a payment process. At the exit gate, the average speed of the vehicle is calculated from the time when the vehicle arrives at the exit gate and the entry time recorded on the toll ticket, and if the average speed exceeds the specified speed, driving We are promoting measures to prevent accidents, such as the attention of staff members.

[0004] Further, by calculating the average speed, it is possible to grasp the running state of the automobile on the highway from the point of the entrance gate to the point of the exit gate where the automobile has entered. By collecting and analyzing the speed, it is possible to constantly check the state of the flow of vehicles on the highway line.

[0005] However, service areas provided with facilities such as a cafeteria and toilets are scattered along the highway, and when a car is parked in these service areas, these services are actually provided. Although the vehicle is not traveling during the parking time, since the data of the parking time is not recorded in the toll ticket, there is a problem that the average speed of the vehicle cannot be accurately calculated at the exit gate.

[0006] That is, for example, when many cars running on a highway are parked in a service area,
The time required to reach from the entrance gate to the exit gate is increased by the time spent in the service area, and naturally the average speed is calculated as a speed lower than the actual traveling speed. This is considered to be due to the fact that the flow of cars is poor when the expressway is congested or due to an accident, etc., and always gives inaccurate information to cars that are going to use the expressway in the future. There is a problem that operation management is performed, for example, by providing the service, which is not preferable.

[0007]

According to the present invention, for example, on a toll road such as an expressway, service areas provided with facilities such as a cafeteria and toilets are scattered on the way, and automobiles are parked in these service areas. Even if you do
By removing those parking times from the calculation time of the average traveling speed of the car, it is possible to calculate the accurate average speed, and to accurately grasp the estimated time to pass through the driving use section, so that more reliable operation speed management The present invention provides a road operation status monitoring system capable of performing the following.

[0008]

And a control unit 40.

Next, a processing procedure according to an embodiment of the road operation status monitoring system of the present invention will be described. Here, a description will be given of a case where a car is used on a highway from Tokyo to Shizuoka and is temporarily parked halfway through one service area. First of all, the nearest Tokyo J in order for the car to enter the highway main line from the general road
At the entrance gate 6 of the CT, the driver can contact the non-contact IC storage medium 5.
Is received (S1). At this time, the entrance gate transmitting / receiving device 7 stores the character information of the entrance gate “Tokyo JCT” in the non-contact IC storage medium 5, the time information “11:20:15” passing through the entrance gate, and the vehicle type “normal”. Is written and then given to the driver.

When the vehicle approaches the A service area on the way, the service area entrance transmitting / receiving device 23 provided at the entrance of the A service area sends the vehicle to the non-contact IC storage medium 5 carried by the driver. The character information of "A" SA indicating the A service area and the time information "12:12:05" when passing through the location are transmitted and written to the storage means of the non-contact IC storage medium 5 (S2). .

Next, when the vehicle returns from the A service area to the main line of the highway, the service area exit transmitting / receiving device provided at the exit of the A service area transmits "A" SA indicating the A service area. And the time information "12:52:25" at the time of passing through the location are transmitted and written in the storage means of the non-contact IC storage medium 5 (S3).

Then, when the vehicle arrives at Shizuoka, the destination, and the driver exits the non-contact IC at Shizuoka JCT, which is the exit gate for exiting the expressway to the general road.
The storage medium 5 is passed to the attendant at the exit gate (S4). The attendant reads the information stored in the storage means of the non-contact IC storage medium collected from the driver of the leaving car by the transmission / reception device 15 for the exit gate (S5), and also reads the exit gate name "Shizuoka JCT". Character information and time information "14:05:48" after passing through the exit gate,
It is stored in the storage means 18. These pieces of information are organized by the control unit and stored in the storage unit 18 in a state as shown in FIG. 3, for example.

Then, based on the charge data registered in the storage means 18 in advance, 4,100 yen is calculated by the charge calculation means 20 as a normal vehicle charge from "Tokyo JCT" to "Shizuoka JCT", and the display means (S
6).

Further, from "Tokyo JCT" to "Shizuoka JCT"
The average speed of the vehicle up to is calculated by the average speed means 21 by the following formula. “Tokyo JCT”
The distance from to "Shizuoka JCT" is calculated as 162 km. First, as a calculation of the time spent in the A service area, (12:52:25)-(12: 12: 0)
5) = 00: 40: 20, indicating that the user stayed for 40 minutes and 20 seconds.

From "Tokyo JCT" to "Shizuoka JC"
The time spent staying in the service area A is subtracted from the total time taken until "T", and the average speed is calculated by the following formula (S7). 162 (14:05:48)-(11: 20: 1)
5) − (0:40:20)｝ = 78 km / h.

Further, the calculated average speed is 78 km / h.
Is the legal speed stored in the storage means 18 of 80 km
/ H, and it is calculated by calculation that the vehicle is traveling at a speed slower than the legal speed by -2 km / h, and a determination that there is no speed violation is displayed on the display means 40 (S8).

The charge data and average speed data calculated by the exit gate transmitting / receiving device 15 are transmitted to the host computer 33 via the communication line 14 such as the Internet, and the host computer 33 uses the data based on the data. The data of all the cars running on the highway are totaled by the fare totalizing means 35 and the average speed totaling means 36, and these data are stored in the storage means 37 (S
9).

The central control center or the like where the host computer 33 is installed monitors whether or not the automobile running on the highway is running smoothly based on the totalized data. Accurate expressway operation status information can be provided to the driver who intends to use the road at any time via the Internet (S10).

[0031]

As described above, the road operation status monitoring system of the present invention has service areas provided with facilities such as cafeterias and toilets along the highway, and automobiles are provided in these service areas. Even when parking the car, the manager can grasp the exact operation status of the car running on the highway because the parking time can be calculated excluding the calculation of the average running speed of the car. It is possible to provide a driver who intends to use the expressway from now on, and to provide an accurate predicted time of passage of the use section, thereby enabling more reliable monitoring of the operation status. .
