RU2539270C1 - Method for interactively ensuring safety at pedestrian crossing - Google Patents

Abstract

FIELD: physics.

SUBSTANCE: pedestrian crossing is provided with a video camera and light emitters. The light emitters form light images on the road surface and/or pedestrian path. The video camera records the number of vehicles and pedestrians, their size, speed, acceleration, correct movement in the pedestrian crossing area and adjacent areas. The video camera transmits video signals to a hardware and software system for processing and analysing the situation and predicting events. The hardware and software system, based on a specified program, transmits an audio signal and/or instruction to the light emitters. In case of emergency, a computer outputs audio and/or personal light signals to road users in order to detect the source of danger and eliminate obstacles. The hardware and software system continuously determines the radio of pedestrians and vehicles, controls vehicle and pedestrian traffic based on characteristics of the time of the day, the number of road users, giving priority to the majority or emergency vehicles or children or senior citizens.

EFFECT: high efficiency of a pedestrian crossing.

Description

The invention relates to methods for ensuring road safety and can be used to reduce the likelihood of cars colliding with a person in a pedestrian crossing zone, as well as to improve the efficiency of the transport and pedestrian system.

An interactive floor is known to which an image is transmitted, capable of changing when a person moves across the floor. Using interactive computer graphics allows you to create a large number of lighting effects, attracting the viewer and involving him in communication.

However, such interactive systems are not designed to provide security at pedestrian crossings.

Known lighting system for pedestrian walkways (Pat. RU 79295). This pedestrian walkway lighting system contains n-elements needed to illuminate the pedestrian walkway, which comprise a plastic housing and lighting means.

Known street lighting lamp with anti-vandal protection (BC Galushchak and others. Innovative directions in street lighting of cities and rural settlements. - Izvestiya Samara Scientific Center of the Russian Academy of Sciences, 11/23/2009, v.11, 5 (2), p.272-275 ) This lamp contains an electric generator, a supercapacitor, an LED panel, a control unit, an ambient light sensor, a motion sensor, an acoustic sensor, an aero-vacuum turbine, glazed boxes, a deflector, air holes, a console, and a battery.

However, the proposed design is not able to automatically signal drivers about the presence of pedestrians in the area of the pedestrian crossing during the day. In the dark, the proposed design includes an LED panel both in the presence of pedestrians and in the presence of cars. Autonomous operation of the structure from alternative energy sources dramatically reduces the reliability of the structure, increases its cost and maintenance costs. Increases the weight of the structure.

Known multi-purpose signaling system with LEDs for pedestrians and traffic control (Pat. RU 2007146239). This system contains a sensitive means, or a digital camera for determining the presence or absence of pedestrians waiting on the sides of the crossing, with a computer program for the control means, for analyzing the presence of pedestrians and for controlling the signal system so as not to change the signal and avoid unnecessary interruption of the traffic if no pedestrians found. The system additionally contains racks with LEDs installed along the stop line of cars at the transition and connected to the control means to prevent drivers from approaching blinking LEDs when the transition signal is working.

However, the proposed design is ineffective in the conditions of a rapidly changing ratio of pedestrians and vehicles at the crossing, it is not able to automatically adjust the transition in emergency situations and reliably signal the danger to road users.

The task to which the claimed technical solution is directed is to create an interactive method for automatically informing and regulating movement at the transition at different times of the day.

The technical result, the achievement of which the claimed invention is directed, is to increase the efficiency of the crosswalk.

The technical result is achieved by the fact that the transition is equipped with a video camera to determine the presence or absence of pedestrians waiting on the sides of the pedestrian crossing, and the new thing is that at a given height above the pedestrian crossing and in the road areas of the vehicle entrance, video cameras and light emitters are installed that form light images on the roadway and / or pedestrian walkway, video cameras record the number of vehicles and pedestrians, their dimensions, speed, acceleration, adequate The frequency of their movement in the pedestrian crossing zone, as well as in the adjacent territories, video cameras transmit video signals to the software and hardware complex for processing and analyzing the situation, predicting events, the software and hardware complex sends a sound signal and / or command to light emitters according to a given program, when in case of emergency situations, the appearance of “blind spots”, the inadequate behavior of participants in the events at the transition, or the predicted collision with a pedestrian, the computer delivers sound and / or personal light signals with Ignals for traffic participants to identify the source of danger and remove obstacles to movement, the hardware-software complex continuously fixes the ratio of pedestrians and vehicles, regulates traffic and pedestrian flows taking into account the peculiarities of the time of day, the number of participants in traffic and pedestrian traffic, giving an advantage to most or special vehicles or children or persons old age.

The invention is illustrated in figure 1.

The method of interactive security at a pedestrian crossing is as follows. At a given height above the pedestrian crossing 1 and in the road zones 2 of the vehicle entrance 3, video cameras 4 and light emitters 5 are installed, forming light images 6 on the roadway and / or pedestrian walkway. Video cameras record the number of vehicles and pedestrians, their dimensions, speed, acceleration, the adequacy of their movement in the pedestrian crossing area, as well as in adjacent areas. Video cameras transmit video signals to a software and hardware complex for processing and analyzing the situation, predicting events, the software and hardware complex sends a sound signal and / or command to light emitters according to a given program, while in cases of “blind spots”, the behavior of participants in events is inadequate the transition or the predicted collision with a pedestrian, the computer gives general or personal light signals to traffic participants to identify the source of danger and remove obstacles to movement, rammno appliance continuously captures the ratio of pedestrians and transport, regulates the transport and pedestrian flows allowing for the time of day, number of participants in the transport and pedestrian traffic, giving the benefit of the majority, or a special purpose vehicle, or children, or elderly persons.

The proposed technical solution will reduce the number of traffic accidents involving pedestrians in the pedestrian crossing zone and increase the safety of road users.
