Definitions

  • the invention relates to a telematic device for enhancement of road-traffic safety, particularly in connection with the movement of rescue vehicles and/or road maintenance vehicles on highways.
  • Such stretches comprise locations where the medial strip is interrupted to enable diverting the traffic into a contra-flow lane when a closure of traffic is unavoidable or level crossing reserved for the rescue vehicles as well as for the vehicles operated by the highway maintenance depots that are responsible for routine and winter maintenance and for regular inspections.
  • the utility vehicles cause an abrupt change of speed within the respective traffic lane. Then, even a slight inattention of an approaching driver may cause a serious traffic accident involving a collision with the utility vehicle turning round or slowly driving away.
  • the stretches including the crossings in the medial strip are not sufficiently marked with visible signs.
  • Such stretches are usually marked with vertical traffic sign A22 "Another danger” provided with a supplementary verbal explanation "Turning of maintenance vehicles” but since the above traffic sign is permanently installed in the respective location, i.e. even when no maintenance vehicles are present, the passing drivers often ignore the sign because they know that an actual danger will only rarely occurs.
  • the telematic device for the enhancement of road-traffic safety, particularly in connection with the movement of road maintenance vehicles and/or rescue vehicles on highways or motorways, according to the present invention, wherein said telematic device comprises variable road signs located along the road at a specific distance in front of the critical traffic area, said variable road signs being controllable by means of a remote switch installed inside a road maintenance vehicle and/or inside a rescue vehicle.
  • the remote switch is designed to switch the variable road signs on and off by means of an encoded radio frequency signals.
  • said critical traffic area comprises a sector of a highway or motorway that is intended for turning of road maintenance vehicles and/or rescue vehicles.
  • the distances of the variable road signs in front of the critical traffic area are in the range of 200 to 400 meters or in the range of 700 to 900 meters, the most preferred embodiment comprising two variable road signs, the first one being placed in the distance ranging from 200 to 400 meters and the other one being placed in the distance ranging from 700 to 900 meters.
  • the variable road sign is supplemented with an additional warning sign and with an additional indication of the remaining distance between the variable road sign and the critical traffic area.
  • the variable road sign may also be supplemented with flashing warning lights.
  • Fig. 1 shows a stretch of a highway with an interrupted medial strip, in which stretch a telematic device for the enhancement of road-traffic safety according to the present invention is installed
  • Fig. 2 shows an exemplary arrangement of the variable road sign that can be used for the telematic device according to the invention.
  • the telematic device will work on the basis of a wireless communication between the respective road maintenance or rescue vehicle 3 and the road signs 4 situated near by the critical area of the highway 1 and intended to enhance the road-traffic safety in that critical area.
  • the driver of the road maintenance vehicle / rescue vehicle 3 arriving in the critical area e.g. approaching the sector reserved for turning such road maintenance vehicles / rescue vehicles 3
  • the remote control switch 5 which sends an encoded signal to the control circuit (not shown) of the variable road sign 4 so as to activate the same.
  • the warning triangle 6 that is typically red and includes a white exclamation mark, illuminates.
  • the indicator 7 informing of the remaining distance to the critical stretch of the highway 1 illuminates and the warning lights 8 begin to flash in order to draw the attention of all drivers to the fact that there is an actual danger in the critical stretch of the highway 1 .
  • the remote switch 5 is designed in the form of a switched transmitter of encoded high frequency signals that are sent to the control circuit (not shown) of the variable road sign 4 in a wireless manner, typically being encrypted by means of a code that is accepted by all the variable road signs 4 within the operational range of the respective road maintenance vehicle / rescue vehicle 3 .
  • variable road signs 4 shown in Fig. 1 are placed in the medial strip 2 of the highway 1 (because the inner traffic lanes adjacent to the interrupted medial strip 2 , which are mostly used for turning of the road maintenance vehicles / rescue vehicles 3 , constitute the most dangerous passages of the highway 1 ), they may be placed along he outer auxiliary lane of the highway 1 , as well. It is obvious that the variable road signs 4 may be simultaneously placed both along the outer auxiliary lane of the highway 1 and inside the medial strip 2 of the highway 1 .
  • the distances between the individual variable road signs 4 and the critical area may be determined in accordance with the actual local traffic situation. Under certain circumstances, it may be preferable to install the first warning sign, e.g., even in the distance 2000 m in front of the critical area.
  • the telematic device for enhancement of road-traffic safety according to the invention may also be used on motorways or other traffic roads.
  • the telematic device according to the invention may be utilized instead of fixed road signs to control the traffic more effectively in such areas of highways where authorised vehicles may move unexpectedly slowly in the fast traffic lane, thus putting the other drivers at risk.
