RU2445419C2 - Method and device to design stop-free and safe passage of crossing lying on same level by vehicles - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: this invention proposes a method and a device to design a stop-free and a safe passage of a street-traffic network crossing lying on the same level by vehicles. It is achieved by the fact that a vehicle does not cross this crossing, but only bypasses it, driving into a road adjacent on the right and turning there, moves back to the crossing and in this manner until the vehicle chooses a road it has to drive on.

EFFECT: invention provides for traffic safety, reduction of transport delays and increased speed of traffic.

Description

The invention relates to the field of organization of road traffic, and more specifically to the organization of movement at the intersection of the road network.

In modern conditions of intensification of automobile traffic, especially at road intersections of the road-road network of large cities, the issue of ensuring traffic safety, reducing traffic delays and increasing speed is an urgent issue. One of the effective ways of fast and safe traffic (passage) at the intersection is the construction of transport intersections at different levels. But they require huge investments and they can not always be used in existing street-road networks.

Currently, traffic management [1] is widely used to organize traffic at intersections that are on the same level. But traffic control has several disadvantages. The variable mode of movement of cars, frequent stops and their accumulation at the intersection leads, in general, to a decrease in the speed of vehicles, to a decrease in the speed of delivery of goods and passengers to their destination, as well as to increased environmental pollution by car exhaust products.

At the intersection also apply the organization of circular motion. But with a high intensity of the flow of cars, especially during rush hours, cars cannot enter the circle, which leads to traffic congestion on the road.

The aim of the invention is a method and device for creating a non-stop and safe passage by cars of the intersection of the road network, lying on the same level.

The method of non-stop and safe passage by cars of the intersection of the road network is as follows.

Regardless of how many roads adjoin the intersection, the car, to get to one of them, does not cross the intersection, but turns right (with right-hand traffic) and leaves on the road closest to the right. It travels along it for some distance, then turns left, goes to the direction of oncoming traffic and moves back to the intersection along it. At the intersection, it turns back onto the road closest to the right and moves along it, etc. In this method, the car does not cross the intersection, but travels around it. If we consider all the roads and cars adjacent to the intersection on these roads, then cars moving along these roads to get to one of the roads behind the intersection must turn right to the nearest road on the right side and drive along it for some distance, then turn left. in the direction of oncoming traffic and drive along it back to the intersection, turn right again onto the road closest to the right, drive along it for some distance and turn left into the direction of oncoming traffic and move to erekrestka, etc., until the car will not choose adjacent to the crossroads at which it needs to move.

At the same time, on the section of the road where the car turns left and leaves for the left extreme lane of the oncoming traffic, guiding safety islands are installed that allow the car to leave for this separate extreme left lane without interference.

Thus, the car, in order to get on one of the adjacent roads to the intersection, this method allows you not to cross the intersection, but go round it, providing uninterrupted and safe traffic. This method also allows you to abandon the use of both a roundabout and traffic lights, and provides conflict-free intersection.

A device for creating a non-stop and safe passage of an intersection lying on the same level is as follows. At the intersection formed by the intersection of several adjacent roads, for example, the intersection of two roads, which can be considered as an intersection with four adjacent roads 1, 2, 3, 4 (Fig. 1), road markings are applied in the form of intersecting solid lines 5 (or borders, etc. . constructions) that prohibit the car from passing through the intersection, and makes it possible to turn the car only to the right on the road adjacent to the right side. In this case, the intersecting solid lines 5 are, as it were, a continuation of the solid lines 6 dividing each of the roads into the directions of oncoming traffic. At a certain distance from the intersection, on each of the roads, these solid lines 6 are interrupted and zones 7 are created for turning the car and moving them to the oncoming traffic lane 8, which are separate leftmost lanes for these directions. Thus, these lanes 8, in this direction of movement, are bounded on the left by the side of solid intersecting lines 5, and on the right by a dashed line 9.

At the end of the width of zone 7, where a solid line 6 begins again, dividing each of the roads into oncoming traffic directions, safety guide islands 10 are installed, which enable cars to turn left and freely enter a separate leftmost lane 8 of the oncoming traffic direction.

In order for the car from road 1 to get onto road 3, which in this case is a continuation of it (Fig. 1), the car needs to be rebuilt and take a separate leftmost lane 8, drive along it, turn to road 2 closest to the right side, drive along it to zone 7, there turn left onto lane 8 of the oncoming traffic direction, and move along this lane to the intersection. At the intersection, turn onto the right adjacent road 3, which you had to get into, and go straight on it.

Thus, this device only by applying road marking allows you to control the traffic flow at the intersection without crossing this intersection, but only bypassing it, stopping on the right adjacent road and turning there, move back to the intersection. Then again call on the road adjacent to the right, and so on until the car selects the road on which it needs to move.

The use of this device will ensure conflict-free, non-stop and safe movement of cars at the intersection, using only a maneuver to rebuild the car from one lane to another on a section of the road in one direction. In addition, this device will allow you to abandon the use of modern expensive traffic light control systems, not always effective roundabout at the intersection and improve the environmental situation in the city.
