Description

System for previous warning of jaywalking on national roadway for drivers}

The present invention is to prevent pedestrians and cyclists who are crossing the road at night and to prevent traffic accidents caused by the crossing, and more specifically, to enter the road or village entrance to the road and the road. By installing a smart precast panel that can detect pedestrians and cyclists at the edge, if the pedestrians and cyclists step on or pass through the smart precast panel, the pedestrians and bicycles are traversed with piezoelectric sensors and motion sensors. The driver detects the driver and emits light from the LED light emitting part installed at the top of the smart precast panel to recognize the presence of pedestrians and cyclists who cross the road through the light to the driver who is driving on the national road and road at night. Pedestrians and bicycle luck in LED panel unit displays the presence of a person on the LED panel unit by text message method and wirelessly transmits the sensing data to the traversalless advance warning system on the national highway for drivers installed at a certain distance from the opposite lane. By displaying on the display, it is possible to recognize that there is a stepless step ahead through a display unit while the driver is driving at a certain distance, so that the stepless advance warning system on the road for the driver can prevent accidents caused by stepping. It is about.

In general, our society today is undergoing rapid development of road traffic, and automobiles are a popular means of transportation, resulting in hundreds of thousands of casualties and property damage every year. Traffic accidents are also changing dramatically due to the increase in human and physical exchanges between regions due to the frequent urbanization of the population, the rapid movement of the economically active population, and the rapid increase of the leisure population following the five-day workweek.

The emergence of automobiles indispensable in modern life has benefited us, but the majority of roads shared by both drivers and pedestrians are occupied by cars, limiting the pedestrian's right to walk. It is causing disastrous results.

Statistics show that the total number of traffic accidents in the first half of this year was 100,000, down 0.9% from the same period last year. As a result, pedestrian traffic accidents increased 1.1 percent from 22,411 to 2,443. The number of pedestrian traffic accidents was 940, accounting for 37.4% of all deaths, of which 24.1% (227) were involved in an accident while crossing the street. Among these, pedestrian crossings were the most frequent during the night time (18: 00 ~ 24 hours).

Most of the pedestrian traffic accidents occur in crosswalks or roads, so the presence of vehicles and pedestrians on certain road sections is very serious. Looking closely at the form of pedestrian traffic accidents, it often occurs in the driver's carelessness, inadvertent driving, and in the driver's self-centered driving behavior. Accidents occur due to the pedestrian culture.

In rural areas, the number of older people is increasing due to aging, and the elderly are more likely to be evacuated to dangerous situations due to the lack of exercise nerves. It is happening frequently.

Conventionally, in order to prevent unauthorized crossings, an endless prevention fence or the like is installed to install posts fixed at regular intervals on the boundary between the road and the sidewalk or the center line of the road, and a panel-type fence such as a chain or a partition is installed on the posts. It is fixed to prevent pedestrians from crossing the road without permission. However, the conventional stepless fence is applied to roads more than two lanes in one way, and the installation work also installs posts on the center line of the road, which causes a lot of manpower and cost, and blocks entry of pedestrians. If the pedestrian crosses the stepless fence beyond the stepless fence, it may cause a larger accident, and the driver may not be aware of the pedestrian crossing. Therefore, the driver cannot perform defensive driving.

The present invention has been made to solve the above problems to detect the pedestrians and cyclists who cross the road at night, the road and the road driver to drive through the piezoelectric sensor and the motion detection sensor, through which the LED emits light A busy driver detects pedestrians and cyclists who walk through LED lights and display messages, and installs a warning system for road crossings for drivers at a certain distance from the opposite lane using USN communication. By transmitting the detected data wirelessly, the driver in the opposite lane can recognize pedestrians and cyclists who are crossing the street at a certain distance, thus minimizing human accidents on the crossing. The purpose is to provide an unauthorized advance warning system.

The present invention provides a pedestrian crossing advance warning system for drivers that can prevent traffic accidents caused by pedestrians and cyclists who are crossing the roads and roads at night to recognize pedestrians and cyclists.
