Description

  • The invention relates to an additional system for increasing safety at a railway crossing, in which a traffic route for road vehicles crosses a rail track for rail vehicles. The invention also relates to a method for increasing the safety of such a level crossing and a computer program for carrying out the method.
  • There are already various approaches to securing level crossings. There is a general distinction between non-technically secured level crossings and various types of technically secured level crossings, e.g. Fuse with traffic light system, level crossings with half-cabinet fuses, level crossings with full barrier closure. For non-technically secured level crossings, the leader of a road vehicle approaching a railroad crossing on a traffic route is obliged to look to see if a train is approaching the railroad crossing and to check whether a whistle signal from a rail vehicle can be heard.
  • According to a survey on the causers of accidents at level crossings in Germany, it is found that the responsibility lies with the road users in approx. 95% of all accidents. Only 5% of accidents are due to human or technical failure on the part of the railway. Much of the accident caused by road users is due to road users' ignorance of the importance of the St Andrews Cross and the safety technology and the required behaviors.
  • The invention has for its object to improve the safety at level crossings, especially in non-technically secured level crossings, with little effort significantly.
  • This object is achieved according to claim 1 by an additional system for increasing the safety at a railway crossing, in which a traffic route for road vehicles crosses a rail track for rail vehicles, with the following features:
  1. a) the auxiliary system has a first lighting device which is arranged on the traffic route to the left of the traffic route with respect to a prescribed direction of travel, and a second lighting device which is arranged on the traffic route to the right of the traffic route with respect to the prescribed direction of travel,
  2. b) the first and the second lighting device each have at least one controllable light source, the light sources being visible from a road vehicle located on the traffic route,
  3. c) the auxiliary system has a control device, which is set up for switching on the light sources of the first and the second lighting device depending on at least one external event, but regardless of whether a rail vehicle is at the railroad crossing or approaching it.
  • With the described additional system, a level crossing can be made safer without major costs. The structural and other technical effort for attaching the first and the second lighting device and possibly a sensor for detecting an approaching road vehicle is comparatively low. In contrast, the improvements in security are significant. By the arrangement of the first and the second lighting device in a certain minimum distance from the traffic route as well as the switching on of their light sources in response to an external event, but not whether a rail vehicle is at the railroad crossing or approaching this, road vehicle drivers can be made to deliberate left and right at the railroad crossing to look to the right to check whether a rail-bound vehicle on the railway line approaching the railroad crossing. In particular, the additional system according to the invention is therefore advantageous for non-technically secured level crossings. But it can also be used advantageously at other technically secured level crossings. At each type of railroad crossing safety is increased.
  • The system according to the invention can thus be an additional system that operates autonomously by the control and safety technology of the railway. As a result, it can remain cheap and remain promising for use.
  • The additional system makes use of automatic processes of visual human perception for its advantageous mode of action. By arranging the first and the second lighting device at a certain minimum distance from the traffic route their light appears in the peripheral field of view of a driver of a road vehicle, so that it looks almost automatically in the direction of the switched-light source. It is advantageous to arrange the first and the second light source close to the rail track, e.g. at a distance of a few meters. As a result, when the light sources are switched on, the driver's gaze is automatically directed in a direction in which a possibly approaching rail vehicle would be recognizable.
  • Advantageously, in the auxiliary system according to the invention, the light of the light sources is automatically triggered, namely as a function of at least one external event, for example, depending on the fact that a road vehicle is approaching the level crossing, but is still at a certain distance therefrom. As a result, the view of the leader of the road vehicle automatically Directed in the direction from which the light comes. If a rail vehicle approaches the railroad crossing, its probability of detection would be increased by the driver of the road vehicle using the system. The correct behavior at the railroad crossing by the road user is thus automatically triggered, even if the driver of the road vehicle, for example, has a poor knowledge of the importance of the railroad crossing signage.
  • Using the additional system according to the invention, it thus does not matter whether a road user can derive from the signage of the level crossing that he is approaching a railroad crossing. Nor is it necessary for him to recall the right mental models from his memory. By the peripheral light stimuli of the first and the second lighting device automatic processes of human perception are set in motion and used to improve security.
  • The first lighting device and / or the second lighting device may in particular be designed as a stationary lighting device, which is arranged at a fixed position with respect to the rail route and the traffic route for road vehicles.
  • According to an advantageous development of the invention, the first and the second lighting device are arranged at least 20 meters away from the middle of the traffic route. According to an advantageous development of the invention, the first and / or the second lighting device are at least 40 meters away from the middle of the traffic route, or at least 60 meters. According to an advantageous development of the invention, the distance of the first and / or the second lighting device from the middle of the traffic route is determined depending on the maximum speed allowed on the traffic route for road vehicles. The higher the permissible maximum speed, the greater the distance between the first and / or the second lighting device of Traffic route arranged.
  • According to an advantageous development of the invention, the additional system for emitting pulsating light, in particular stroboscopic pulsed light, is set up by the light sources of the first and / or second lighting device. Experiments have shown that in such pulsating light stimuli people's attention is particularly high. The pulsating light may e.g. be generated by the fact that the light sources of the first and / or the second lighting device by means of the control means are switched on and off pulsating, or in that the light sources themselves are formed as pulsating light sources, e.g. as LED flash light.
  • According to an advantageous embodiment of the invention, the additional system for emitting light in different and / or changing colors of the first and / or the second lighting device is set up. As a result, a further increase in attention among road users can be achieved. Thus, e.g. change the color of a light source in temporal change. If a plurality of light sources are present in a lighting device, they can also be formed with different colors or controlled in different colors by the control device.
  • According to an advantageous development of the invention, an external event, by virtue of which the first and / or the second lighting device is switched on for the purpose of emitting light, is the approach of a road vehicle traveling on the traffic route to the railroad crossing. For detecting a road vehicle on the traffic route, the additional system may have at least one sensor. It is advantageous here if the sensor for detecting a road vehicle is set up at a distance of at least 20 meters from the level crossing, or at least 40 meters, or at least 70 meters. In any case, the approach of a road vehicle on the traffic route is thereby clearly recognized prior to the time at which the road vehicle reached the railroad crossing. Thus, a timely switching on the light sources of the auxiliary system is possible, so that the attention of the leader of the road vehicle is directed sufficiently early in the direction of the peripheral areas of the railroad crossing and a timely braking response in response to the maximum speed allowed.
  • According to an advantageous embodiment of the invention, the distance of the road vehicle from the railroad crossing, in which the first and / or the second light emitting device is switched on for the delivery of light, depending on the permissible on the roadway for road vehicles maximum speed set. The higher the permissible maximum speed, the greater the distance from the road user to the level crossing, the lighting devices are triggered.
  • The sensor can be realized according to different physical principles, e.g. in the form of an induction loop embedded in the lane of the traffic route, as a radar, camera or ultrasonic sensor, e.g. is located at the edge of the traffic route, or in the form of a geolocation sensor (e.g., GPS) of the road vehicle so that the geoposition of the road vehicle e.g. can be transmitted via a Car2X system, a mobile network or any other communication system to the control device of the additional system according to the invention. In this way, the controller may also detect the approach of a road vehicle on the traffic route as an external event. In this case, the auxiliary system itself does not have the sensor, but an interface for communication with a sensor of the road vehicle or with an associated evaluation device of the road vehicle.
  • According to an advantageous embodiment of the invention, the additional system is adapted to turn on the occurrence of an external event, the light sources of the second lighting device at a different time than the Light sources of the first lighting device. Thus, the gaze of the leader of the road vehicle can be directed first in one direction and then in the other direction.
  • According to an advantageous embodiment of the invention, the additional system is adapted to turn on the occurrence of an external event, the light sources of the second lighting device at a later time than the light sources of the first lighting device. In this way, the light sources of the light direction in the direction of travel left of the traffic route are first turned on, and only then the light sources arranged in the direction of travel right of the traffic signal. In this way, the correct behavior of the driver of the road vehicle when approaching the railroad crossing can be further promoted.
  • According to an advantageous embodiment of the invention, the distance of the first lighting device from the center of the traffic route substantially corresponds to the distance of the second lighting device from the middle of the traffic route. Thus, the first and the second lighting device are arranged with respect to their spacing symmetrical to the traffic route. Furthermore, it can be provided that substantially an equilateral triangle is formed between the position at which the presence or approach of a road vehicle on the traffic route is detected via the sensor, and the position of the first and the second lighting device. Such a geometry has been found to be particularly advantageous for influencing the attention of the driver of a road vehicle when approaching a railroad crossing.
  • The above-mentioned object is further achieved by a method for increasing the safety of a railroad crossing, in which a traffic route for road vehicles crosses a rail track for rail-bound vehicles, with the following features:
    1. a) it is checked by means of a sensor, whether a driving on the road Road vehicle approaches the railroad crossing,
    2. (b) If it is found that a road vehicle traveling on the traffic route is approaching the railroad crossing, the light sources of a first traffic signal located on the traffic lane to the left of the traffic route, and / or the light sources, before the road vehicle reaches the railroad crossing a second lighting device, which is arranged with respect to the prescribed direction of travel on the road to the right of the traffic route, regardless of whether a rail vehicle is at the railroad crossing or approaching it, the light sources visible from a located on the roadway road vehicle are.
  • Hereby, too, the advantages explained above can be realized. The method can advantageously be developed with the previously described functions of the auxiliary system, e.g. the delivery of pulsed light by the light sources, the delivery of light in different and / or changing colors from the light sources or the staggered switching between the light sources of the first and the second lighting device.
  • The object mentioned at the outset is also achieved by a computer program having program code means, in particular program code means, which are stored on a machine-readable carrier, set up to carry out the method of the previously described type, when the computer program is executed on a computer. Hereby, the advantages explained in the introduction can also be realized. The computer can e.g. be a computer of the control device of the additional system according to the invention, i. e.g. a microprocessor or microcontroller of an electronic control device.
  • The invention will be explained in more detail using an exemplary embodiment using a drawing.
  • The drawing FIG. 1 shows a arranged at a railway crossing additional system from a bird's eye view.
  • A traffic route 5 for road vehicles 6, e.g. a federal highway or a country road. The traffic route 5 has a lane 51 with a prescribed direction of travel 52, and a lane 50 for the opposite direction of travel. On the lane 51 is a road vehicle 6, which moves in the prescribed direction 52.
  • Furthermore, a rail track 7 is shown for rail vehicles. The rail track 7 crosses the traffic route 5 at a railroad crossing 8. The railroad crossing 8 is e.g. a non-technically secured railroad crossing on which, for example, a signage 9 is present for securing.
  • There may also be a second rail track to allow simultaneous rail traffic in two directions.
  • To improve the safety at the level crossing 8 there is installed an additional system according to the invention. The additional system has a first lighting device 1, a second lighting device 2, an electronic control device 3 and a sensor 4. The sensor 4 and the first and the second lighting device 1, 2 are connected via electrical lines to the control device 3, which are shown in the drawing as dotted connecting lines between the components 1, 2, 3, 4.
  • The first and the second lighting device 1, 2 are clearly spaced from the traffic route 5, that is arranged at least 20 meters away from the center 53 of the traffic route 5. For traffic routes with relatively high permitted maximum speeds, eg highways or highways, even greater distances than 20 meters are advantageous. The first and the second lighting device 1, 2, however, are arranged in the vicinity of the rail track 7 in order to direct the gaze of the driver of the road vehicle 6 in the direction of the rail track 7. The lighting devices may be located on both sides of the rails, ie from the approach direction of the road vehicle in front of or behind the track body. The lighting devices 1, 2 have one or more controllable light sources 10, 20 which can be switched on and off by the control device 3 and / or can be actuated to emit pulsating light. The light sources 10, 20 need respect. The respective lighting device 1, 2 does not radiate the light in a 360 ° angle, but it is sufficient if a radiation 11 or 21 is provided, which is aligned in the direction of the traffic route 5 and the it allows the driver of the road vehicle 6 to perceive the emitted light well before reaching the level crossing 8, for example, after passing the sensor. 4
  • The sensor 4 has a detection beam 40, over which a road vehicle 6 passing the detection beam 40 can be detected, e.g. in the form of reflected ultrasonic waves or interrupted or reflected light, e.g. in the form of a light barrier or a retro-reflective sensor.
  • If a road vehicle 6 traveling through the detection beam 40 is detected by the sensor 4, this is detected in the control device 3 and used as an external event for switching on the light sources 10, 20 of the lighting devices 1, 2. The controller 3 switches e.g. Immediately after receiving the signal from the sensor 4, the light sources 10, and a little later the light sources 20. The lighting devices may e.g. be switched off again after a definable number of pulsations or a definable time interval. The light of the light sources 10 and 20 may be e.g. be controlled so that it pulsates ten times in alternation in different colors, e.g. in the colors pure white and pink.
  • As a result, the driver of the road vehicle 6 becomes shortly after passing the vehicle Detection beam 40 caused by the light signals to look first in the direction of the first lighting device 1, and then in the direction of the second lighting device. 2
