JPH0329091A - 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 store information by a camera and a recording part. 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 6 are started to record picture information. Thus, picture information of vehicles passing on the road side zone is stored to easily clamp down vehicles which illegally pass the road side zone at the time of traffic congestion.

Description

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

2. Description of the Related Art 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 patrol cars.

Problems to be Solved by the Invention However, with the conventional enforcement method 1b, there is a problem in that enforcement 1 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 crack down on violating vehicles even during traffic jams, where enforcement was nearly impossible in the past. The object of the present invention is to provide an excellent roadside traffic enforcement device.

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 determine the type of vehicle (car/motorcycle) and whether or not the vehicle is passing along the roadside. When a violation vehicle is detected, the camera records the information. By recording information in the section, it is possible to easily control 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 traffic volume is calculated by storing information using the camera and the recording unit. This system has the advantage of making it easier to crack down on roadside traffic violations that occur during traffic jams, which frequently occur due to the increase in traffic jams, and to reduce the number of vehicles passing along the roadside that can cause emergency vehicle traffic obstructions in the event of an accident. It has a great effect.

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 is connected to a processing device 3 as shown. The housing 3 is composed of a sensing signal processing section 4 and a recording section 5, which are connected as shown in the figure. Furthermore, the six cameras are coupled to the processing device of the camera 3 as shown.

Next, the operation of the above embodiment will be explained. The vehicle detectors 1 and 2 detect the presence of the υ vehicle, and transmit sensing signals to the sensing signal processing section 4. In step 4, it is determined whether the vehicle is a car and is passing along the roadside belt according to the overall flowchart in FIG. Record as image information.

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. 5.

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

When a passing vehicle is detected by the vehicle detectors 1 and 2 (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 Fi process is terminated. 1. If you are driving in a car and are passing along the roadside, 5 and e are activated and recorded as image information (step 14). , 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...min 3.195 m Motorcycle length...rnax 2.385 m 1 9
8 (From the Automotive Guidebook), it is possible to distinguish between a car and a motorcycle based on the length of the vehicle. One! When the sensing pulses sent from two vehicle sensors overlap as shown in the timing chart in Figure 6 (vehicle sensor 1 and 2 are turned ON simultaneously)
) (vehicle detectors 1 and 2 are each 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 they are both ON at the same time, it is determined that the vehicle is a car (Nutep 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 sensor is measured, and by calculating this time, it is determined whether or not the vehicle is passing along the roadside belt. First, the judgment is made based on whether the reflection time is long or short after an arbitrarily set time t.
If this is changed to flowchart 1, the result will be as shown in FIG. 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).

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.

As described above, according to the above embodiment, by storing images of vehicles passing on the roadside as image information, it is now possible to easily take control of vehicles violating roadside traffic during traffic jams, which was difficult to enforce in the past. It has the advantage that it can be tightened.

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 has the advantage that it is possible to easily control vehicles violating roadside traffic during traffic jams, which was difficult to control in the past. have and,
Furthermore, by enforcing roadside traffic control, 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 caused by emergency vehicles, such as when an accident occurs.
