Description

DESCRIPTION

Management system for the circulation of vehicles in urban and interurban roundabouts.

Sector of the technique

Circulation of vehicles and Road Safety.

BACKGROUND OF THE INVENTION

Roundabouts are an element of regulation of urban and interurban traffic.

We understand by roundabout all that intersection equipped with a central obstacle, materially impassable and surrounded by an annular causeway, which facilitates the organization of crossings of roads, through the revolving circulation.

Numerous circular crosses existed before the arrival of the roundabouts, including the Place de l'Etoile at the Arc de Triomphe in Paris, Columbus Circle in New York, and several circles in Washington, DC. However, the operation and input characteristics of these circles differed considerably from modern roundabouts. The first roundabout was built at Letchworth in 1909, originally intended as a traffic island for pedestrians.

The widespread use of roundabouts began in the 1960s when Frank Blackmore invented the mini roundabout to overcome his capacity limitations and safety issues.

The roundabouts provide, with respect to the traffic signals:

- Speed and fluidity in the crossing.

- Greater flexibility in the itineraries (allows a greater number of itineraries, the complete change of direction or correction in case of mistake, taking a full turn to take the correct direction).

- Provides greater clarity for users (more indications can be given with fewer signals).

- Minimizes environmental impact (occupies less land than a regulated crossing with pre-selection lanes, and generates less noise and pollution due to the fluidity it brings to circulation.

- It is more economical for the administration (it occupies less public space and generates less exploitation and maintenance costs than a traffic light).

The general rule to be taken into account when driving through a roundabout is regulated in article 21, section 2.C of the Road Safety Law (LSV), according to which:

"In the absence of a signal that regulates the right of way, the driver is obliged to assign it to vehicles approaching from the right, except in the following cases:

In the roundabouts, those who are inside the circular way will have preference of step on which they try to accede to those ".

However, when the roundabouts are multi-lane, the maneuver made by vehicles that are already circulating through them and intend to change lanes to leave the roundabout, is governed by Art. 28.2 of the LSV, which states that:

"Any lateral displacement maneuver involving lane change shall be carried out respecting the priority of the one that circulates in the lane intended to be occupied".

At the time of accessing a roundabout, vehicles that circulate through it have the right of way over those that try to access the roundabout. Therefore, when entering a roundabout, you will always have to yield to cars passing through it. inside.

To exit the roundabout, we will always have to do it from the right lane (outer lane). In the event that this maneuver is not possible, we will complete the roundabout until we are allowed to change lanes.

Explanation of the invention

The roundabouts have become one of the most dangerous traffic points both in the city and in the intercity route. The circulation of vehicles in the roundabouts of two or more interior lanes, presents safety and fluidity drawbacks both in the access, as in the interior circulation and the exit of the same, due to the speeding, and mainly to the incorrect use of the interior lanes, using the outer lane for circulation in search of the chosen exit, and the inner lane for diagonal circulation, which decreases safety and fluidity.

The current signage of the roundabouts, does not allow the use of the access and exit lanes, in cases where there are more than one.

The object of the invention is to improve in practice, traffic safety and fluidity in urban and interurban roundabouts, by incorporating standardized road markings, which guide and manage traffic.

By incorporating the road markings that are the subject of this invention, we achieve:

At the access to the roundabout

This management system improves the location of the vehicles in the access to the roundabout, selecting the correct lane for the circulation inside, depending on the exit to take, with the consequent fluidity in the access to the roundabout.

In circulation inside the roundabout

The use of the inner lane in the roundabout, improves the attention of the driver during the location of the exit lane, which will have access, making a lateral change to the outside, prior to this. All indicated by arrows and the continuous line that defines the outputs. This entails a decrease in the speed of the layout, greater control of the vehicle and with it, better safety conditions.

At the exit of the roundabout

This management system forces out the roundabout, vehicles that circulate in the outer lane of the ring, to leave it for the next exit, without producing any alteration in the rest of vehicles that circulate or wish to access it, giving utility to all access lanes, internal circulation of the roundabout, and mainly to the exit lanes.

PREFERRED EMBODIMENT OF THE INVENTION

For the correct incorporation of the road markings and depending on the number of access lanes, inner circulation lanes and exit lanes, the direction or lane selection dates will guide us to select the correct access, the exit arrows will inform us of the place by which to accede to the chosen exit, by means of a lateral change towards the outer lane, and the continuous line, will indicate us the exit of the roundabout. (Figures 1 and 2).

The road markings to be incorporated in the roundabouts are the following:

Direction or lane selection arrows M-5-2

An arrow painted on a roadway divided into lanes by longitudinal markings means that every driver must follow with his vehicle or animal the direction or one of the directions indicated in the lane through which it circulates.

Discontinuous longitudinal marks M-1.3

A discontinuous line on the roadway is intended to delimit the lanes in order to guide the movement, and means that no driver must travel with his vehicle or animal on it, except when necessary and the safety of the traffic allows it. These marks usually exist in most of the roundabouts, in order to separate the two interior circulation lanes.

Output arrows M-5.3

Tell drivers where they can start the lane change to use an exit lane.

Continuous longitudinal marks M-2.2

Continuous line on the road means that no driver with his vehicle or animal must cross it or circulate on it, forcing the driver to leave the roundabout by the chosen exit. The length of these lines will depend on the characteristics of each roundabout.

Other elements to incorporate:

Cat eyes or marks with extruded paint on the pavement.

Its installation along the continuous longitudinal marks will produce, when passing over the wheels of the vehicle, a vibration that would contribute to inform the driver that he is performing an unauthorized maneuver. The extruded paint on the pavement will improve the visibility of the line in dark and rainy conditions.

Signs limiting the speed R-301

With the installation of speed limitation signs at 30 km / h at the access roads to the roundabouts, we will achieve:

- Increase the safety of circulation.

- Increase the efficiency of circulation.

Pre-signaling signals.

The pre-signaling signal indicates the directions of the different exits of the next roundabout. If any inscription appears on a blue background, it indicates that the exit leads to a motorway or highway.

The correct way of circulation in the roundabouts R.I., once incorporated the horizontal signaling, and depending on the number of lanes of access and exit, will be the following:

Rotonda R.l. 1.2.

One access lane, two inside and one outside (Fig. 3).

If you want to leave the roundabout for the first exit.

Access the outer lane of the roundabout (right lane). From this lane you will not be able to continue driving in the outer lane of the roundabout. The continuous line that separates both inner lanes from the roundabout does not allow it.

Exit the roundabout for the first exit.

If you want to leave the roundabout for the second exit

Access the inner lane above the dashed line that separates both interior traffic lanes.

Indicate your intention to change lanes using the right indicator. After the continuous line of the first exit, the dashed line allows access to the outside lane. The continuous line forces the driver to exit through the second exit of the roundabout, as in the lane outside can not continue circulating. The continuous line that separates both inner lanes from the roundabout does not allow it.

If you want to exit through the third exit

Access the inner lane above the dashed line that separates both interior traffic lanes.

Indicate your intention to change lanes using the right indicator. After the continuous line of the second exit, the dashed line allows access to the outer lane. The continuous line forces the driver to exit at the third exit of the roundabout, since the outside lane will not be able to continue circulating. The continuous line that separates both inner lanes from the roundabout does not allow it.

If you want to make a U-turn

Access the inner lane above the broken line separated by both lanes of traffic.

Indicate your intention to change lanes using the right indicator. After the continuous line of the third exit, the dashed line allows access to the outer lane. The continuous line forces the driver to exit through the fourth exit of the roundabout, as it can not continue to circulate in the outer lane. The continuous line that separates both inner lanes from the roundabout does not allow it.

Rotonda R.l. 2.2.

Two access lanes, two internal circulation and two exit lanes (Fig. 4).

If you want to exit the roundabout by the first exit on the right.

Go through the right lane and access the outer lane of the roundabout.

Exit the roundabout for the first exit. The continuous line forces the driver to exit at the first exit of the roundabout, since the outside lane will not be able to continue circulating. The continuous line that separates both inner lanes from the roundabout does not allow it.

In this way, if the first exit of the roundabout has two lanes, you can also exit through it from the inside lane of the roundabout, safely.

If you want to leave the roundabout for the second exit

Go through the left lane and access the inner lane of the roundabout above the broken line that separates both lanes of traffic.

Go through the inside lane of the roundabout and indicate your intention to change lanes using the right turn signal. After the continuous line of the first exit, the dashed line will allow you to access the outer lane of the roundabout. Exit the roundabout for the second exit. The continuous line that separates both inner lanes from the roundabout does not allow it to continue circulating inside the roundabout.

In this way, if the second exit of the roundabout has two lanes, you can also exit through it from the inside lane of the roundabout, safely.

If you want to exit the roundabout by the third exit

Go through the left lane and access the inside lane of the roundabout above the Circuile through the inner lane of the roundabout and indicate through your right turn signal, your intention to change lanes. After the continuous line of the second exit, the broken line will allow you to access the outer lane of the roundabout. Exit the roundabout for the third exit. The continuous line that separates both inner lanes from the roundabout does not allow it to continue circulating inside the roundabout.

In this way, if the third exit of the roundabout has two lanes, you can also exit through it from the inside lane of the roundabout, safely.

If you want to leave the roundabout for the fourth exit

Go through the left lane and access the inner lane of the roundabout above the broken line that separates both lanes of traffic.

Go through the inside lane of the roundabout and indicate your intention to change lanes using the right turn signal. After the continuous line of the third exit, the dashed line will allow you to access the outer lane of the roundabout. Exit the roundabout for the fourth exit. The continuous line that separates both inner lanes from the roundabout does not allow it to continue circulating inside the roundabout.

In this way, if the fourth exit of the roundabout has two lanes, you can also exit through it from the inside lane of the roundabout, safely.
