JPH0329090A - Road side zone passage crackdown device - Google Patents

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 and 2, a detection pulse signal is transmitted to a detection signal processing part 4. 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 5 and a camera 7 are started to record picture information, and data is transmitted to the higher-order system by a transmission part 6. Thus, vehicles which illegally pass the road side zone at the time of traffic congestion and are conventionally difficult to clamp down are easily and quickly clamped down.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a roadside traffic enforcement device for controlling vehicles violating the roadside of a road such as a motorway that has a sideband where traffic is prohibited.

BACKGROUND OF THE INVENTION Conventionally, vehicle detectors have been used to identify the types of passing vehicles and to measure traffic volume, and enforcement of roadside traffic violations has been carried out by traffic patrollers.

Problems to be Solved by the Invention However, the conventional enforcement methods described above have 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 makes it possible to easily and quickly stop illegal vehicles even during traffic jams, where it has been nearly impossible to stop them. The purpose of the present invention is to provide an excellent roadside traffic enforcement device that enables the following.

Means for Solving the Problems In order to achieve the above object, the present invention uses a vehicle sensor not only for the conventional purpose of 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 identify the vehicle type (car/two-wheeled vehicle) and determine whether the vehicle is passing along the roadside.When a violation vehicle is detected, the camera records the By recording information on the system and transmitting the data to the host system, it is possible to easily and quickly crack down on vehicles violating roadside lanes.

Therefore, according to the present invention, a vehicle (automobile) passing along the roadside is detected by calculating 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 host system. By doing this, the roadside traffic violation D that can be pressed during traffic jams that frequently occur due to increased traffic volume.
Tightening can be performed easily and quickly, and furthermore, it has the 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. In FIGS. 1 and 2, 1 is a vehicle sensor 1, 2 is a vehicle sensor 2, and is connected to the processing device 3 shown in the figure. 1 and 3 are composed of a sensing signal processing section 4, a recording section 6, and a transmission section 6, which are connected as shown in the figure. Further, a camera 7 is connected to the processing device 3 as shown.

Next, the operation of the above embodiment will be explained. The presence of a vehicle is sensed by vehicle sensors 1 and 2, and a sensing signal is transmitted to a sensing signal processing section 4. In step 4, according to the overall flowchart in FIG. 3, it is determined whether the vehicle is a car and is passing along the roadside belt, and if so, the recording unit in step 6 and the camera in step 7 are activated to record an image. Record as information. Furthermore, at the same time as the sudden movements of 6 and 7, data is transmitted from the transmission unit of 6 to the upper system.

Next, a method for determining a roadside belt violation vehicle according to the above embodiment will be explained with reference to the flowcharts of FIGS. 3, 4, and 6 and the timing chart of FIG. 6.

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

When a passing vehicle is sensed by the vehicle detectors 1 and 2 (step 11), a sensed P/V signal is transmitted to the sensed signal processor. 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 a roadside belt (step 13). If the determination result is that no two-wheeled vehicle is passing along the side strip of the road, the process ends. If the vehicle is a car and is passing along the roadside, 6 and 7 are activated and recorded as image information, and 6 transmits the data to the host system (step 14).

Next, the vehicle determination process will be explained according to the flowchart of FIG. 4 and the timing chart of FIG. 6.

When vehicle detectors 1 and 2 are installed at a certain interval (for example, 2.
5m car length... 63.1e6m Motorcycle length-
--mhx 2.3 8 5 m 1 9 8 B), it is possible to distinguish between a car and a two-wheeled vehicle based on the length of the vehicle. In other words, as shown in the timing chart in Fig. 6, when the sensing pulses sent from the two vehicle sensors are electric (vehicle sensors 1 and 2 are turned on simultaneously) and when they do not overlap (vehicle sensors 1 and 2 are turned on at the same time) ON) occurs. If this is made into a flowchart, it will look like the one shown in Figure 4. In step 21, it is determined whether the vehicle sensors 1 and 2 are in the ON state at the same time. If the vehicle is in the simultaneous ON state, it is determined that the vehicle is a car (step 22), and if not, it is determined that the vehicle 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 sensor is measured, and by calculating this time, it is determined whether or not the vehicle is passing along the roadside belt. In other words, the judgment is made based on whether the reflection time is longer or shorter than an arbitrarily set time t.

If this is made into a flowchart, it will look like FIG. 6. Nutep 31 determines 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 (7. step 33).

Furthermore, as shown in FIG. 2, if this device is installed at a certain distance, it is also possible to determine whether the vehicle is running continuously on the roadside.

In this way, according to the above embodiment, by storing images of vehicles passing on roadside lanes as image information and transmitting the data to the higher-level system, it is possible to easily control vehicles that violate traffic lanes in traffic jams, which has been difficult to control in the past. It also has the advantage of being able to be cracked down quickly.

Furthermore, the above-described embodiment has the 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 has an advantage in that it is possible to easily and quickly crack down on vehicles violating roadside lanes during traffic jams, which has been difficult to crack down on in the past. has.

Further, by enforcing roadside traffic control 1, 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.
