Description

Traffic situation precision measurement system

The present invention relates to a traffic situation precision measurement system, and more particularly, to a traffic situation precision measurement system that can accurately grasp the current information at the site as well as the management office, as well as accurately measure the traffic volume and speed of the vehicle at any time. It is about.

In general, the system for observing the current traffic situation is to install a video camera at a location that is easy to grasp the situation of the road and output the captured situation as a video using means such as CCTV, etc. Observe the current traffic situation.

In addition, it is not a system to grasp the current traffic situation, but it installs the unmanned camera at the point where the driver is likely to drive at a high speed, photographs the vehicle traveling at a certain speed when driving the vehicle, and notifies the driver later. Ventilation prevention systems are in place in some areas.

However, in the former system, the current road traffic situation can only be identified by traffic flow, congestion, and slow motion, and the speed of the vehicle cannot be accurately determined, and these systems can detect traffic violations such as speeding. There is a disadvantage that the driver can not obtain the traffic compliance effect and the traffic accident prevention effect can not be obtained.

In addition, in the latter case, it is not only difficult to grasp the overall road traffic situation, but also, when the inter-vehicle distance is short because the unmanned camera is not repeatedly operated, there is a problem that only the preceding vehicle is photographed to satisfy the use for complete surveillance. .

On the other hand, in recent years, the electromagnetic wave having a specific wavelength and frequency is transmitted and reflected at two or more places, and the speed of the driving vehicle is calculated by a computer and outputted by means of a digital display. The system has been developed and operated to observe traffic conditions or to inform other drivers, but it does not operate continuously and repeatedly, so accurate traffic information is not known. The driver of a vehicle not only did not realize that his vehicle speed appeared outside, but was not able to obtain a satisfactory effect on the detection of a traffic violation vehicle.

In order to solve the above problems, the present invention outputs the driving speed of the car according to the required time of the car that has passed a certain distance so that the driver can see, and at the same time the unmanned camera to grasp all of the above situation By continuously shooting the situation and outputting the recorded situation as a video using means such as CCTV, so that the site as well as the management organization can accurately grasp the current information, and the traffic volume and speed at any time The purpose is to provide accurate traffic condition measurement system that can accurately measure and notify the general driver, which facilitates traffic communication, and achieves the effect of the driver's compliance with traffic laws and prevention of traffic accidents.

The traffic situation precision measurement system of the present invention for achieving the above object is a predetermined period passing time measurement means of the vehicle for measuring the time it takes for the vehicle to pass a certain section, and input in advance corresponding to the required time measured by the measurement means Speed recognizing means according to the measurement time for confirming the speed, speed display means for displaying the speed information output from the speed recognizing means, situation recognizing means for continuously recognizing the situation in which the speed is displayed while the vehicle passes; Characterized in that the output means for outputting the situation recognized by the situation recognition means as an image.

Hereinafter, the traffic state precision measurement system according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a traffic situation precision measurement system according to the present invention. As referred to herein, the traffic situation precision measurement system 1 includes a time required for measuring a section passing time of a vehicle for measuring a time taken for the vehicle to pass a certain section, and a requirement measured by the measuring means 2. The speed recognizing means 3 according to the measurement time for checking the pre-input speed corresponding to the time, the speed display means 4 for displaying the speed information output from the speed recognizing means 3, and the vehicle passing through It consists of situation recognition means 5 which continuously recognizes the situation in which the speed is displayed, and output means 6 which outputs the situation recognized by the situation recognition means 5 as an image.

The time period measuring means 2 for passing the predetermined section of the vehicle recognizes that the vehicle passes the starting point and recognizes the starting point passing recognition means 21 of the vehicle operating the timer, and recognizes that the vehicle passes the end point. And end point passing recognition means 22 for stopping the operation of the timer, and measurement time transmission means 23 for transmitting the information of the time measured by the timer to the speed recognition means 3.

The speed recognizing means 3 according to the measurement time includes the transmitted time recognizing means 31 for recognizing the information of the required time transmitted from the measuring time transmitting means 23 and the corresponding time required in advance. And a speed checking means 32 for checking the speed input, and a confirmed speed transmitting means 33 for transmitting the checked speed to the speed display means 4.

Looking at the operation of the traffic situation precision measurement system (1) configured as described above are as follows.

First, a predetermined section of the road is selected, and starting and ending point passing recognition means 21 and 22 of the vehicle are installed at starting and ending points of a certain section, respectively, and starting and ending point passing recognition means 21 and 22 of the vehicle. As the timer is operated and stopped, the time required for passing a certain section of the vehicle is measured.

Here, the distance between the start point passing recognition means 21 and the end point passing recognition means 22 may be arbitrarily selected, but if it is too short, it may be recognized that two or more vehicles are passed when a long vehicle passes. There are disadvantages, and if it is too long, one or more vehicles can pass together in a certain section, so the present invention is applied only to the preceding vehicle and the following vehicle is not applied to the system, so the interval of 20m is most desirable. Do.

In addition, the starting point passing recognition means 21 and the end point passing recognition means 22 of the vehicle is grounded by a vehicle commonly used in the technical field to which the present invention belongs, for example, when the vehicle passes, so that a signal is operated. A device such as a device or a device for transmitting a radio wave of a specific frequency from one side and detecting a vehicle passage according to a time difference of a signal received may be used.

When the required time of the vehicle passing the predetermined section is measured in the same manner as described above, the measurement time transmission means 23 having the same configuration as a known transmission means recognizes the measured time required by the speed recognition means 3. And the time recognizing means 31 recognizes the transmitted information and outputs the recognized information to the speed checking means 32.

The speed checking means 32 checks the speed by substituting the required time measured by the passing time measuring means 2 through a predetermined section for each speed of the integer.

For example, if you set a certain distance to 20m and drive 120Km / hr as a speed corresponding to an integer according to the formula “Speed = Distance / Time”, you need to enter the time required to drive 20m, that is, 0.6 seconds. The 20m driving time corresponding to each speed is inputted by the method, and the speed is determined by measuring the time taken for the vehicle to travel 20m and recognizing the speed corresponding to the measured time.

The identified speed transmitting means 33 transmits the speed confirmed by the above-described method to the speed displaying means 4, displays the traveling speed of the vehicle on which the speed displaying means 4 is traveling, and the driver of the vehicle that is driving. Of course, the vehicle driver of vehicles with short distances can easily recognize the speed of the vehicle, and the speed of the vehicle is displayed until the speed of the vehicle driving behind it is displayed, so that the driver of the next vehicle can check it. do.

However, since such a configuration can be observed or measured only in the field, the situation recognition means 5 is installed at a position where it is possible to easily identify both a certain section and an area where the speed display means 4 is installed, and it is wired or Receives wirelessly and outputs to output means 6 so that all situations can be observed at a glance at a distance or wirelessly, and speed can be measured precisely, so any traffic situation in any area can be informed with the current vehicle driving speed. It will provide accurate traffic information.

The situation recognition means 5 may use a device such as a known camera, and the speed display means 4 and the output means 6 may use a liquid crystal display device or a monitor, and various measurement means constituting the present invention; The recognition means can be integrated into a computer.

2 is an operation flowchart of the traffic situation precision measurement system according to the present invention, the operation is as follows.

First, the timer is activated when it is recognized that the vehicle has passed the starting point, and the timer is stopped when the vehicle passes the end point. Thereafter, the speed corresponding to the required time measured by the operation of the timer as described above is confirmed, the speed confirmed by the transmission is displayed by the speed display means, and the display state is photographed and output to the remote management organ.

As described above, the traffic situation precision measurement system according to the present invention is a predetermined section in a state in which the driving speed of the car according to the required time of the car that has passed a certain distance based on the formula of speed = distance / time is input to the computer in advance. Measure the time required for passing cars and display the speed corresponding to the measured time so that the driver can see it, and install an unmanned camera in a location where all of the above situations can be grasped. By using the means such as CCTV and outputting the recorded situation, it is possible to accurately grasp the traffic situation at the site and the management institution, and to have the driver comply with the traffic laws.
