Abstract

PURPOSE:To facilitate crackdown of illegal passing on a road side zone by detecting a vehicle (automobile) passing the road side zone by the arithmetic processing of the vehicle detection signal obtained from a vehicle sensor to not only store information by a camera and a recording part but also transmit data to a higher-order system. CONSTITUTION:When a passing vehicle is detected by vehicle sensors 1 to 3, a detection pulse signal is transmitted to a detection signal processing part 5. This detection pulse signal is subjected to arithmetic processing to discriminate whether the passing vehicle is an automobile or a two-wheeled vehicle and whether it passes the road side zone or not. If the detected vehicle is an automobile and passes on the road side zone, a recording part 6 and a camera 8 are started to record picture information and data is transmitted to the higher- order system by a transmission part 7 after the passing speed is calculated. Thus, picture information of vehicles passing on the road side zone is stored and data is transmitted to the higher-order system to easily and quickly clamp down vehicles which illegally pass the road side zone at the time of traffic congestion and vehicles which pass the road side zone at an illegal speed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is used to crack down on vehicles violating the roadside strip and speeding vehicles on the roadside strip of a road such as a motorway that has a prohibited roadside strip. Relating to roadside traffic enforcement devices.

Conventional technology Conventionally, vehicle detectors have been used to identify the types of vehicles passing by and to measure traffic volume, and enforcement of roadside traffic violations and speeding violations within roadside zones has been carried out by traffic patrol cars. There is.

Problems to be Solved by the Invention However, the conventional enforcement method described above has a problem in that enforcement becomes nearly impossible when it is difficult for patrol cars to pass, such as during traffic jams.

The present invention solves these conventional problems, and allows for easy and quick enforcement of violating vehicles even during traffic jams, where enforcement was nearly impossible in the past. The purpose of this invention is to provide an excellent roadside traffic enforcement device that enables traffic control.

Means for Solving the Problems In order to achieve the above object, the present invention uses a vehicle sensor not only for the purpose of detecting the presence or absence of a vehicle, but also for detecting the presence or absence of a vehicle.
A vehicle detector and a sensing signal processing unit are installed, and by calculating the detection signal and reflection time, it is possible to distinguish the vehicle type (car or motorcycle) and determine whether or not to pass along the roadside belt, and calculate the traffic speed, thereby detecting a violation vehicle. By recording information on the camera's recording unit and transmitting the data to the host system, it is possible to easily and quickly crack down on vehicles violating the roadside lane and speeding vehicles within the roadside zone. It is something.

Therefore, according to the present invention, a vehicle (automobile) passing along the roadside is detected by processing the vehicle detection signal obtained from the vehicle sensor, and the information is accumulated by the camera and the recording unit and the data is transmitted to the upper system. By doing so, traffic volume increases and il3! ; Enforcement of roadside traffic violations can be carried out easily and quickly by pressing the button when traffic is delayed. In addition, speed enforcement within the roadside belt can be carried out at the same time. Furthermore, it has an excellent effect of reducing the number of vehicles passing along the roadside, which can be a cause of obstruction to the passage of emergency vehicles in the event of an accident.

Embodiment FIGS. 1 and 2 show the structure of an embodiment of the present invention. Referring to FIGS. 1 and 2, 1 is a vehicle sensor 1, 2 is a vehicle sensor 2, and 3 is a vehicle sensor 3, which is coupled to a processing device 4 as shown. . Further, numeral 4 is composed of a sensing signal processing section 5, a recording section 6, and a transmission section 7, which are connected as shown. Furthermore, 8
The camera is connected to the processing unit 4 as shown in the figure.

Next, the operation of the above embodiment will be explained. 1. According to the overall flowchart in the figure, it is determined whether the vehicle is a car and is passing along the roadside strip, and if so, it is recorded as image information by activating the recording unit 6 and the camera 8. . change (7 at the same time as C, 6 and 8 start)
Data is transmitted from the transmission unit to the upper system.

Next, Fig. 3 shows the method for determining roadside lane violation vehicles according to the above embodiment. This will be explained with reference to the flowcharts in FIGS. 4 and 6 and the timing chart in FIG.

First, the entire process will be explained according to the flowchart in FIG.

1. When a passing vehicle is detected by the vehicle detectors 2 and 3 (step 11), a sensing pulse signal is transmitted to the sensing signal processing section. By calculating and processing the sensed Barne signal, it is determined whether the passing vehicle is a car or a two-wheeled vehicle (step 12), and it is further determined whether the vehicle is passing along the roadside belt (step 13). If the determination result is that the two-wheeled vehicle 1 is not passing through the roadside belt, the process ends. If the vehicle is a car and is passing along the side of the road, after calculating the traffic speed (step 14), e and 8 are activated to record as image information, and 7 transmits the data to the host system. (Step 15).

Next, the vehicle determination process will be explained according to the flowchart of FIG. 4 and the timing chart of FIG. 5.

When vehicle detectors 1 and 2 are installed at a certain interval (for example, 2.
6m Vehicle length...mm3,195 rn *
Motorcycle length: max 2.388 m, 1
9 8 8 Automobile Guide Guide) allows the commander to distinguish between automobiles and motorcycles. Two cabinets. As shown in the timing chart in Figure 6, there are two cases in which the sensing pulses sent from the two vehicle sensors overlap (vehicle sensors 1 and 2 are ON simultaneously) and when they do not overlap (vehicle sensors 1 and 2 are each ON). arise. If this is made into a flowchart, it will be the fourth
It will look like the figure. In step 21, it is determined whether the vehicle sensor 1.2 is in a simultaneous KON state. If they are both ON at the same time, it is determined that the vehicle is a car (Step 22), and if not, it is determined that it is a two-wheeled vehicle (Step 23).

Next, the road side strip traffic determination process will be explained according to the flowchart of FIG. 6.

The reflection time from the vehicle of the ultrasonic waves emitted by the vehicle detector is determined, and by calculating that time, it is determined whether the vehicle is passing along the roadside belt. The judgment is made based on whether the reflection time is longer or shorter than the arbitrarily set time tp.

If this is made into a flowchart, it will look like FIG. 6. In step 31, it is determined whether the reflection time is less than or equal to the set time t. If it is less than the set time t, it is determined that the vehicle is traveling on the roadside (step 32), and if not, it is determined that the vehicle is traveling in the passing lane or the overtaking lane (step 33).

Next, speed calculation will be explained. As shown in Fig. 2, the distance between the vehicle detectors is Lm and L2m, and as shown in Fig. 6, the time at 1 when a vehicle sensor turns on and the next vehicle sensor turns on is T1 (S). ,T2(s
), then the following equation is used.

V = (3.8 XL1)/T1Ax/h1 V = (3.6 XL)/T2b/h2
2 ■=(v1+v2)/2k! lV/h As shown in Figure 2, if this device is installed at a certain distance, it will also be possible to determine if the vehicle is running continuously on the side of the road.

In this way, according to the above embodiment, by storing images of vehicles passing along the roadside as image information and transmitting the data to the higher-level system, it is possible to improve roadside traffic during traffic jams, which has been difficult to enforce in the past. This has the advantage that it is possible to easily and quickly control illegal vehicles and speeding vehicles within roadside lanes.

Furthermore, according to the above-described embodiment, there is an excellent effect of reducing the number of vehicles passing along the roadside that become a traffic obstruction factor for emergency vehicles when an accident occurs.

Effects of the Invention As is clear from the above-mentioned embodiments, the present invention makes it possible to easily and quickly catch vehicles violating roadside traffic violations and vehicles violating speeding in roadside zones during traffic jams, which was difficult to enforce in the past. It has the advantage of being able to be tightened. Further, by controlling roadside traffic, the number of vehicles passing along the roadside is reduced, and as a result, it is possible to reduce the number of traffic obstruction factors for emergency vehicles such as when an accident occurs.
