Abstract

FIELD: transport.

SUBSTANCE: unregulated pedestrian crossing consists of pedestrian path on traffic way of motor road which pedestrian path is marked at edges on sidewalks by road signs. On their pillars, video cameras are installed combined with device for vehicle speed measurement. The video cameras are oriented towards oncoming transport. The video cameras monitor vehicle presence on a road, and vehicle speed measurement device fixes vehicle speed at a distance of 100 and 50 meters from nearest edge of pedestrian crossing. At these distances additional lines of road marking are drawn, and additional informative signs are installed. When traffic regulations violations by vehicle drivers are fixed the vehicle forced stopping device is actuated. This stopping device is located at 5 meters before nearest edge of pedestrian crossing. At the moment of proposed device actuation, headlamp light is reflected by light-reflective coating of suddenly appearing obstacle thus attracting driver's attention.

EFFECT: lower accident rate on unregulated pedestrian crossings.

Description

The invention relates to the field of traffic regulation.

A pedestrian crossing is a place of increased danger, on it there is an intersection at the same level of traffic and pedestrian flows. In this conflict zone, traffic participants - both pedestrians and drivers - very often make mistakes and miscalculations, leading to injuries and deaths.

According to the traffic police, two types of pedestrian crossings are known throughout the world: an adjustable pedestrian crossing consisting of a pedestrian crossing sign, traffic lights for regulating traffic and pedestrians on both sides of the road, a zebra on the roadway and two transverse lanes on the road surface indicating the stopping place transport before the crossing, and unregulated pedestrian crossing, consisting of a sign on the side of the road, parallel white stripes - zebras, painted on the road surface.

To improve the safety of pedestrians crossing the carriageway through a regulated pedestrian crossing, a solution is known having patent RU 2416821 C1, G08G 1/005, E01F 9/04, 12/10/2009. According to this invention, a pedestrian crossing consists of traffic lights for vehicles and pedestrians mounted on poles along the roadsides, a pedestrian zebra for pedestrian traffic, made in the form of longitudinal white stripes, painted on the road surface along the roadway, two white transverse stripes on each side carriageway in front of a pedestrian zebra, indicating the stopping lines of vehicles before crossing. In the pavement, on the same level with it, metal boxes are installed with lanterns and armored glass mounted in them in reflectors with a corrugated inner surface to ensure a bright glow in all directions. The boxes also have glass heating wires controlled by a device with an LED placed in the internal space of the reflector of each lamp, and a condensate removal system from the lamps and boxes in the ground. Boxes with green lanterns are installed between the white stripes of a pedestrian zebra and have two modes of illumination - constant with green pedestrian and red traffic lights and blinking while the red pedestrian and yellow traffic lights are on. Boxes with red lanterns are installed in the white transverse lines of the vehicle stop before the crossing and glow with a steady red light when the green pedestrian, red transport and when the red pedestrian and yellow traffic lights burn together, prohibiting traffic and allowing pedestrians to complete the transition. This patent is taken as a prototype.

The disadvantage of this invention is the impossibility of its use for unregulated pedestrian crossings.

To improve the safety of pedestrians moving on an unequipped pedestrian crossing, devices for forcibly stopping a vehicle are known.

For example, a device is known as described in patent DE 2515308 A1, E01F 13/00, 01/08/1976, comprising a flexible tape with piercing elements fixed to it.

A disadvantage of the known device is damage to the vehicle during its forced stop, as well as low efficiency due to the impossibility of hidden placement on the road and unexpected use.

Also known is a device for forcing a vehicle to stop, including a container filled with filler (see RU 2132531 C1, F41H 11/08, F42B 23/00, 06/27/1999).

The disadvantage of this device is damage to the vehicle when it is forced to stop, as well as low efficiency due to the impossibility of hidden placement on the road and unexpected use.

A device for forcing a vehicle to stop, including a container filled with a filler (RU 2229552 C2, E01F 13/12, 04/13/2001) is known. The container is made of waterproof material, and dispersed material is used as the filler, the level of which coincides with the level of the roadway, and the device includes fluid supply and drainage systems located in the bottom of the tank, creating a liquid flow ascending from the bottom up, translating the dispersed material into a pseudo-liquid state, and a liquid discharge system that creates a downward flowing liquid, transferring the dispersed material into a dense state.

Finally, there is known a device for forcibly stopping a vehicle (RU 100091 U1 E01F 13/08, 06/21/2010), comprising a housing mounted in a recess of the roadway, inside of which a drive shaft is connected, connected with an obstacle, a cover pivotally connected to the shaft, a latch, remote control panel, a signal receiver from the control panel, characterized in that the barrier is made in the form of one or more box-shaped nozzles mounted on the shaft, one or more surfaces of each of which are made with artificial neros In fact, the lock is made in the form of a ratchet interacting with an adjustable spring mechanism associated with the shaft and the cover. This utility model is taken as a prototype.

The objective of the invention is to reduce the accident rate at unregulated pedestrian crossings by influencing the psychology of the behavior of drivers when crossing a pedestrian crossing.

The problem is solved due to the fact that in the arrangement of the unregulated pedestrian crossing, road signs and road markings are used to inform the driver about the approach to the unregulated pedestrian crossing, equipped with a device for the forced stop of vehicles, consisting of a frame to which the covers and shaft guides are attached with electromagnets holding the spring-loaded shaft with rings treated with a reflective compound, connected to an electric motor controlled to with a limit switch and fixed to the frame through a cable located on the stopping line of vehicles before the crossing and triggered in the event of two events: the presence of a pedestrian at the crosswalk, fixed by weight sensors installed in platforms located on the sidewalk and roadway; the absence of a decrease in speed in a vehicle approaching a pedestrian crossing, as determined by a video camera combined with a vehicle speed measuring device located on a post with a traffic sign.

The proposed device unregulated pedestrian crossing is presented in figure 1. For 100 m to the nearest edge of the pedestrian crossing, road marking 2 is applied on the roadway 2 “Double strip of approach to the pedestrian crossing” in the form of parallel sequences of contrasting shaded triangles and a road sign 3 “Attention! Crosswalk!". 50 m to the nearest edge of the pedestrian crossing, the road marking 4 “Approach to the pedestrian crossing” is applied in the form of a sequence of contrasting shaded triangles and the road sign 5 “Driver! Skip the pedestrian! ” 5 m to the nearest edge of the pedestrian crossing, a stop line 6 is applied in the form of a transverse strip on the road surface and a device is installed to force stop the vehicle 7. A video camera 10 is installed on each of the supports 8 and 9 of the road signs opposite the roadway and combined with the device for measuring vehicle speed, directed towards oncoming vehicles 11. The pedestrian crossing on both sides has platforms 12 with built-in weight sensors, one of which is date IR weight 16 on one side and a weight sensor 20 on the opposite side are located on the sidewalk 13, and the other is a weight sensor 18 on one side and a weight sensor 19 on the opposite side on the carriageway 1. For the guaranteed movement of pedestrians on the pedestrian crossing 14 on the sidewalk 13 a guard 15 is provided on each side. Signals from the weight sensors 16, 20 and 18, 19 and the video camera 10 enter the control unit 17 (FIG. 2, FIG. 3). The device for the forced stop of the vehicle 7 (Fig. 1) consists of electromagnets 21 (Fig. 4), a shaft 22 with removable rings treated with a reflective composition 23, guides 24, mounted on the frame 27, under the action of springs 25, an electric motor 26, fixed on the frame 27 and the rotating pulley 28, on which the cable 29 is wound, fixed at the other end to the shaft 22. The power supply from the electric motor 26 is disconnected and connected to the electromagnets 21 automatically after the operation of the limit switch 30. a sealed container 31, which are attached to the guide 24 and the frame 27.

The principle of operation of the proposed device unregulated pedestrian crossing is as follows.

Subject to the Rules of the road regarding the passage of unregulated pedestrian crossings by drivers of vehicles, the system operates as follows (figure 2). A pedestrian steps onto a platform 12 equipped with a weight sensor 16, the signal from which enters the control unit 17. Next, the system waits for a signal from the weight sensor 18 - this will mean that the pedestrian has stepped on the roadway, after which the control unit accesses the video camera 10, combined with a device for measuring vehicle speed. A video camera records the presence of vehicles on the carriageway and, if available, their speeds are measured at a distance of 100 m - V1 and 50 m - V2 from the pedestrian crossing. The speed V1 should be 40 ± 10 km / h, and V2 <V1. In this case, the system detects the vehicle deceleration and the signal for triggering the device to force stop the vehicle is not supplied. The control unit expects signals from sensors 19 and 20, which will record that the pedestrian has crossed the roadway. The system provides for the appearance of a pedestrian from the opposite side. The triggering of the sensors in this case differs only in the reverse sequence.

If there are several pedestrians moving in opposite directions, their total weight and approximate travel time of the carriageway, calculated by the formula, will be taken into account:

t = S / Vп,

where t is the expected time from the moment the signal from the sensor 16 or 19, s; S is the width of the roadway, m;

Vп - pedestrian speed, m / s, Vп≈1,2 m / s.

In case of non-compliance with the Rules of the road regarding the passage of unregulated pedestrian crossings by drivers of vehicles, the system operates as follows (figure 3). A pedestrian steps onto a platform 12 equipped with a weight sensor 16, the signal from which enters the control unit 17. Then the system waits for a signal from the weight sensor 18, after the signal is received, the control unit accesses the video camera 10, combined with a device for measuring vehicle speed. The video camera detects the presence of vehicles on the roadway and measures their speed V1 - at a distance of 100 m and V2 at a distance of 50 m from a pedestrian crossing. In case of exceeding the speed V1 of 50 km / h and (or) in the case of V2> V1, the control unit opens the power supply circuit of the electromagnets 21 (Fig. 4) of the device for forcibly stopping the vehicle 7 (Fig. 1). In this case, the shaft 22 (Fig. 4) with removable rings treated with a reflective compound 23 rises up along the guides 24 mounted on the frame 27 under the action of the springs 25. The maximum lifting height is not more than 10 cm. After 5 seconds (the minimum time required for overcoming a vehicle moving at a speed of over 40 km / h, a distance of 50 m), the control unit supplies voltage to an electric motor 26, mounted on a frame 27 and a rotating pulley 28, on which a cable 29 is wound, fixed at the other end to the shaft 22. Disconnecting the power from electric motor 26 and its connection to the electromagnets 21 is carried out automatically after the operation of the limit switch 30. The device is closed by casings 31, which are attached to the guides 24 and the frame 27.

The system provides for the appearance of a pedestrian from the opposite side. The sequence of operation in this case is similar.

At the moment the device for forced stopping the vehicle is triggered, the headlights are reflected from the reflective coating of the surface of the sudden obstacle, attracting the attention of the driver, who will be forced to stop in front of the obstacle, allowing pedestrians to finish crossing the road.
