Description

In the presence of traffic jams for ambulances there is a problem to get through the traffic jam.

Ambulance calls are very urgent, the condition of the patient can be so difficult that not only every minute, but even seconds, are available to provide him with urgent care. It can be an emergency operation, on which a person’s life depends.

Under these conditions, an ambulance in a traffic jam is completely unacceptable.

Ambulances are equipped with a special sound signal (siren) and a light signal.

According to the rules of the road, all other cars are obliged to give way to the car with the special signal turned on, to ensure its immediate movement in the right direction.

Unfortunately, in urban conditions, drivers do not always fulfill this humane universal human mission - to let the ambulance forward.

However, in some cases, with all the desire of the drivers, this is impossible to do:

1) An ambulance cannot go around a traffic jam that occupies the entire carriageway. In these cases, the SP car is forced to go into the oncoming lane or move along the sidewalk. In both cases, the risk of injury to road users and pedestrians is increased.

2) The SP machine itself is located inside the cork (“sandwiched” between other machines) and cannot continue to move.

To ensure in all cases the ambulance (SP) can move, it is proposed to install a special device on the machine (let's call it Barmashnet). This device transmits via the Internet a signal to traffic lights that are in the way of the joint venture machine from its emergency call to a medical center (hospital, place of operation). An Internet signal switches oncoming traffic lights to green for unobstructed movement of the SP machine.

All traffic lights that are in the way of movement are equipped with a device for receiving an Internet signal. Each of these traffic lights becomes a virtual object. An electronic number is assigned to these objects to be able to send an Internet signal to it.

The traffic light is equipped for this with a special receiving device. The received signal is converted so that the traffic light switches to a green light for a certain time to pass the SP machine in the desired direction. (At the same time, the signals of this traffic light are switched respectively for other directions of movement).

Thus, this traffic light turns from a normal traffic control object operating according to a given program within the network and becomes a traffic control object, which can be additionally controlled “outside”, depending on the situation at the given moment at a given intersection. A traffic light receives this signal over the Internet from a Barmashnet device installed on the SP machine.

Electronic numbers of all traffic lights that are in the way of the movement of the joint venture machine to the place of operation are entered into the Barmashnet device. These traffic lights sequentially receive (via the Internet) a signal about the need to switch the traffic light to green to ensure unhindered passage of the SP car. The sequence and time of switching the signal is set depending on the distance of the SP machine to the traffic light. The distance to the traffic lights and the location of the vehicle in a given section of the road can be determined using the GPS system.

If the joint venture machine cannot currently go around the traffic jam or the joint venture machine itself is inside the traffic jam (“squeezed” between other cars), then the possibility of removing it from the traffic jam is provided due to the gap between the cars, allowing it to maneuver between standing cars.

Despite the measures taken, the formation of cork is now commonplace. Cork is recognized by all as a harmful phenomenon. However, when it occurs, attention is not paid to the shape (location) of cars inside the cork. Of course, the cork itself is largely spontaneous. The beginning of its formation (and sometimes the place) is not always amenable to accurate prediction. There are places on the roads where traffic jams on certain days and hours can be predicted with high probability.

But you can partially adjust the shape of the cork, in particular the placement of machines inside the cork.

The existing rules of the road do not indicate what the minimum distance should be between cars so that a car that wants to get out of the traffic jam by maneuvering can fulfill this intention. Now, when traffic jams form in multi-lane traffic, cars usually approach each other at a minimum distance (they stop one after the other almost close to each other). At the same time, a joint venture car “jammed” in a traffic jam, wishing to perform any maneuver, cannot perform it. To the left and right of it are other cars. They do not have the ability to shift left or right. There is another car in front of this car. There is also a car at the back. It turns out that the “jammed” joint venture car can only start moving forward together with other cars when the whole traffic jam begins to advance. The delay in the plug can last a fairly long period of time.

Maneuvering inside the cork is only possible if there is a “gap” between the cars in the cork.

It is appropriate to recall that motorcycles and scooters (without a stroller) never get stuck in traffic. They can freely maneuver between standing machines.

It is necessary to create the possibility of maneuvering in traffic jams and for cars.

To do this, they must stop in a traffic jam at a certain distance from each other, allowing for maneuvering. In our opinion, the length of the car going behind can be taken as the minimum clearance.

The size of this gap does not have any effect on the capacity of the road. In the process of driving cars can move at any safe distance from each other. But before stopping in areas where jamming is possible, this minimum clearance between them must be observed. The presence of such a gap allows maneuvering between cars in traffic jams for ambulances, emergency, fire, police and other services without the need to go into the oncoming traffic lane and sidewalks. (Further consideration of the operation of the device is carried out on the example of ambulances (SP).

The required minimum clearance between the cars can be set using the driver’s eye and with a simple location device.

To do this, a sensor for a weak, for example, ultrasonic radiation directed to the rear car is installed on the car in front. A receiver for this signal is mounted on a vehicle going behind. If the distance between the cars is less than the specified value, then the receiver will catch a signal, a light signal will light up on the control panel of the rear car. This indicates that the driver of the rear vehicle should increase the clearance between the vehicles. If the receiver does not pick up the ultrasonic signal, then the light on the panel does not light up, the driver is informed that the distance between the cars is not less than the preset one, allowing maneuvering.

Now the need for such an arrangement of cars in traffic jams is not specified. This does not allow the “jammed” JV machines to get out of the traffic jam. Obviously, in the future, when creating a new version of the traffic rules, which will include such a concept as “traffic jam formation”, creating a clearance between the cars in the traffic jam will be a prerequisite for drivers.

Thus, the Barmashnet device and the gap between the cars make it possible to solve a very important task under traffic conditions - to ensure unimpeded movement of the joint venture machine.

In the absence of traffic jams, the use of this device is most often not required. Drivers in most cases obey the sound and light signals of the SP cars and pass them. This device is supposed to be used in the presence of "impenetrable" traffic jams. Such traffic jams will exist until the global task is solved - the elimination of traffic jams. Using the device during this time will save the lives of many people.

As noted above, Barmashnet is a device that allows you to send via the Internet a signal to switch certain traffic lights to green. The list of these traffic lights (their electronic numbers), the switching sequence, the duration of the burning of the green signal (if necessary) are included in the device’s work program.

The Barmashnet device can be permanently installed on a JV car or can be removable. The receiver of the Internet signal installed at the traffic light is a simple device similar to the receiver of this signal of any personal computer.

The cost of a set of "transmitting + receiving device" is approximately $ 100.
