RU2658210C1 - Road user warning system of pedestrians presence on or near pedestrian crossing - Google Patents

Abstract

FIELD: traffic control systems.

SUBSTANCE: invention relates to the field of road safety. System includes a power system that can operate from a public grid or can be an autonomous, battery-powered pedestrian crossing that is limited to four posts, in each of which sensors for detecting the presence of objects, laser visible light generator, and the existing columns contain one laser beam generator acting horizontally perpendicular to the roadway from one column to the other, located on opposite sides of the carriageway, in this case, in conjunction with laser light generators, prismatic or rotary laser devices are built in, and the inclusion of laser visible beam and prism or rotary laser devices comes from transmitting a signal to them from sensors detecting the presence of objects when a pedestrian passes between posts or next to posts. Mode of operation of laser visible-beam generators and prism or rotary laser devices provides for both their joint operation, and separately, and also in a flashing mode.

EFFECT: road users are warned about the presence of pedestrians at or near a pedestrian crossing.

Description

The warning system for road users about the presence of pedestrians at or near a pedestrian crossing belongs to the field of road safety and can be used to ensure the safe passage of pedestrians through the carriageway at a pedestrian crossing and to prevent traffic accidents in the pedestrian crossing area.

Known invention (US Pat. RU 2539270) that implements a method of interactive security at a pedestrian crossing, which consists in the fact that at a given height above the pedestrian crossing and in the road areas of the entrance of vehicles are installed cameras and light emitters that form light images on the roadway and / or a pedestrian path, 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 e in the adjacent territories, video cameras transmit video signals to a hardware-software complex for processing and analyzing the situation, predicting events, the hardware-software complex sends a sound signal and / or command to light emitters according to a given program.

The disadvantage of this method is the complexity of the design, the high cost of equipment, installation, commissioning and maintenance during operation.

The invention is known (US Pat. RU 2506368), which implements a method of notifying drivers about the presence of a pedestrian at a pedestrian crossing, including lighting a pedestrian crossing when a pedestrian presence sensor is triggered at a pedestrian crossing. Lighting a pedestrian crossing is carried out by visible, regardless of the time of day, light using an LED spotlight.

The disadvantage of this method is the presence of a beam fixed to the support located in the pedestrian crossing area above the lanes of vehicles, which limits the height of the roadway.

Known pedestrian crossing (US Pat. RU 156964), limited to four columns containing several generators of laser beams, acting in the same direction, but in different planes and at different angles (prototype).

A disadvantage of the known traffic control system at a pedestrian crossing is the driver’s difficulty in viewing moving objects located in relation to the driver behind the numerous visible oblique rays, as well as the lack of a warning system for drivers (the inability to provide the driver with information) about the presence of a pedestrian at or near a pedestrian crossing.

The task to which the proposed system is aimed is to ensure the safety of pedestrians at the pedestrian crossing and to provide drivers with information about the presence of the pedestrian crossing and pedestrians at the crossing.

The technical result, to which the claimed technical solution is aimed, is to warn road users about the presence of pedestrians at or near a pedestrian crossing, including a power supply system that can operate from a public utility network or can be autonomous, battery-powered, a pedestrian crossing, which is limited by four columns, each of which has built-in sensors for detecting the presence of objects, a visible laser beam generator, and existing columns the kiosks contain one laser beam generator that acts horizontally perpendicular to the carriageway from one column to another, located on different sides of the carriageway, while prism or rotary laser devices are built into the columns together with laser beams (like a building laser level ), and the inclusion of laser visible beam generators and prism or rotary laser devices occurs from the transmission of a signal to them from sensors for detecting the presence of objects when passing a pedestrian between columns or next to columns. The operating mode of the visible laser beam generators and prism or rotary laser devices provides for their joint work, as well as separately, as well as in flashing mode.

The essence of the claimed system is illustrated in FIG. 1, which depicts a pedestrian crossing.

The list of positions:

1 - column;

2 - laser beam generator;

3 - sensors for detecting the presence of objects;

4 - prism or rotary laser devices (as a building laser level).

The crosswalk containing the zebra type marking is equipped with additional equipment, which is a system of four columns installed at the corners of the crosswalk 1 with generators of visible red laser beams 2, prism or rotary laser devices (like a building laser level) 4, sensors detecting the presence of objects 3.

The system operates as follows.

When a pedestrian passes between columns, the sensors for detecting the presence of objects include visible laser beam generators and prism or rotary laser devices. The laser beam generator transmits the beam in a horizontal direction perpendicular to the carriageway from one column to another, located on different sides of the carriageway. The prism laser device has LEDs, the narrow luminous flux of which with the help of a prism is converted into a laser plane, when projected onto the roadway a visible light line is formed. At a certain tilt angle, the visible light line becomes equal to the width of the lane or the entire carriageway. Drivers of all traffic lanes, including the second and next traffic lanes, are informed about the presence of a pedestrian at the crosswalk.
