CZ201076A3 - Telematic device for increase of road traffic safety - Google Patents

Abstract

A road safety telematics device, in particular for the movement of maintenance vehicles (3) and / or integrated rescue systems, includes variable traffic signs (4) located at a speedway at a distance from a critical point in road traffic that is manageable a remote switch (5) stored in a maintenance vehicle (3) and / or an integrated rescue system. The remote traffic sign variable switch (5) is configured to switch the traffic sign variables coded by a radio signal. A critical point in road traffic is the place for turning vehicles (3) of maintenance and / or integrated rescue systems on motorways (1) and / or expressways. As a rule, the variable traffic sign (4) is located at two distances both before and after the critical point in road traffic, usually at a distance of about 300 meters and about 600 meters ahead and beyond a critical point in road traffic.

Description

Telematic equipment to increase road safety

Field of technology

The invention relates to a telematics device for increasing road safety, in particular when moving integrated rescue system vehicles and / or road maintenance vehicles on motorways.

State of the art

At a time of increasing motorization, there is often a very high degree of traffic not only in urban areas, but also in high-capacity line constructions in urban areas. In addition, it operates a significant proportion of accidents on high-density motorways and expressways due to instability of the traffic flow, which has fatal consequences in connection with the high speed of vehicles.

For these reasons, too, there is an increasing amount of investment in telematics systems on all major roads in the European Union. Detectors are installed informing about traffic intensities, traffic flow speeds, etc. At the same time, significant amounts are invested in distribution channels in the form of variable traffic signs and other sophisticated technologies. Many traffic problems and dangers exist only temporarily or in places that do not receive such attention. However, under the circumstances, these places can be very dangerous, even tragic.

For example, there are places on motorways and expressways that are designed to "turn maintenance vehicles". These are the places of the crossings of the middle dividing strip for the transfer of traffic to the opposite lane during closures, or the crossings for level turning of the integrated rescue system vehicles, but also the road manager's vehicles during routine maintenance, winter maintenance and inspections. Vehicles using these turning points cause a sharp change in speed in the motorway lane. Only a slight inattention of the arrival

-2drivers can cause a serious accident with a rotating or slow-moving vehicle.

At present, the crossing points of the middle dividing strip are not marked visibly enough. Although they are marked with the vertical traffic sign A22 "Other hazards" with the additional table "Turning maintenance vehicles", because this traffic sign is permanently in place even when no vehicles are turning here, drivers very often tend to ignore it, because drivers they know that the real danger is only a fraction of the time that this road sign stands by the road.

The essence of the invention

These shortcomings of the prior art are largely eliminated by telematics devices for increasing road safety, in particular when moving integrated rescue system vehicles and / or road maintenance vehicles on motorways or expressways, the essence of the invention being that it includes variable traffic signs, located at the roadside in front of a critical point in road traffic, which are controllable by a remote switch stored in the road maintenance vehicle and / or the integrated rescue system. In a preferred embodiment of the telematics device according to the invention, the remote variable traffic sign switch is designed to switch the variable traffic signs by a coded radio signal. In another preferred embodiment of this telematics device, the critical point in road traffic is the place for turning the integrated rescue system vehicles and / or the road maintenance vehicles on motorways and / or expressways. In other preferred embodiments of this telematics device, the spacing of the variable traffic sign in front of the critical point in the road is in the range of 200 to 400 meters or in the range of 700 to 900 meters, but it is best if two variables are located in front of the critical point in the road. traffic signs, one at a distance from

-3,200 to 400 meters and the second at a distance of 700 to 900 meters. It is advantageous if the variable traffic sign is a sign indicating other dangers and if it is provided with an indication of the distance of a critical point in road traffic from this variable traffic sign and, if appropriate, flashing warning lights.

Overview of figures in the drawings

The invention will now be described in more detail with reference to the accompanying drawings, in which FIG.

Examples of embodiments of the invention

Fig. 1 shows a section of the motorway 1 with an interrupted center lane 2 to allow the maintenance vehicles 1 or the integrated rescue system to turn. Along the motorway 1, in both directions of traffic flow before the interruption of the dividing middle lane 2, variable traffic signs 4 are placed at a distance of approximately 600 and 300 meters.

Fig. 2 shows an exemplary embodiment of the variable traffic sign 4. In the middle there is a warning triangle 6 with an exclamation mark indicating possible danger on the LV motorway. 8.

In operation, the telematics device will operate on the principle of wireless communication of the maintenance vehicle 3 or the integrated rescue system with traffic signs 4 located near the critical point on the motorway 1 and designed to increase road safety at this critical point. Driver of 3 maintenance vehicle or integrated rescue system,

-4 arriving at a critical point, such as the turning point 3 of the maintenance vehicles 3 or the integrated rescue system, if he plans to turn his vehicle 3 over the separating center lane 2, the remote switch 5 closes, which sends a coded signal to an unidentified variable traffic sign control circuit 4 and it is activated. The warning triangle 6, usually red, lights up with a white exclamation mark, the critical point distance indicator 7 on motorway 1 also lights up and the warning lights 8 start flashing to warn all drivers that the danger at the critical point of motorway 1 is really acute. .

The remote switch 5 is designed as a switched transmitter of a high-frequency coded signal, wirelessly switching a non-illustrated control circuit of the variable traffic sign 4, generally operating in a code used by all variable traffic signs 4 within the scope of the respective maintenance vehicle 3 and / or integrated rescue system. .

Although in Fig. 1 the variable traffic signs 4 are shown as being located along the outer edge of the motorway 1, they can be located in the separating middle lane 2 of the motorway 1, of the rescue system are the most dangerous places of the motorway 1. The variable traffic signs 4 can of course be located simultaneously both along the outer edge of the motorway 1 and in the separating middle lane 2 of the motorway 1.

The distances of the variable traffic signs 4 from the critical point can be determined according to local conditions, so that in some places it may be advantageous to draw attention for the first time to an approaching critical point, for example already at a distance of 2000 m.

Although the situation on the motorway 1 is described in the exemplary embodiments, it is possible to use a telematics device for increasing road safety according to the invention also on expressways or other roads.

Industrial applicability

The invention can be used for more efficient traffic management instead of fixed markings in places where vehicles, with the exception of the fast lane, can move unexpectedly slowly and thus be a risk for other road users.
