Definitions

  • the invention relates to a method for traffic control at a railway crossing according to the preamble of patent claim 1 and an apparatus for performing the method according to claim 7.
  • a road intersect with one or more lanes for road vehicles, hereinafter referred to as vehicles, and a single or multi-track railway line for rail vehicles, which share a common danger area.
  • the danger area comprises a conflict area on which the movement strips of the incompatible traffic streams are superimposed.
  • visible areas are kept free from both sides of the road on both sides of the railroad track, and danger signs, beacons and other road traffic signs are set up.
  • the priority of the railway is indicated to the road users by the setting up of St. Andrews crosses.
  • level crossings are often secured by technical fuses, such as lights with yellow and red signal generator, red flashing lights, barriers or half barriers.
  • Light signals at the level crossing must be included in a traffic light program for traffic control at the intersection.
  • the relevant time constant of the level crossing is composed of a first part-time corresponding to the time needed to influence the traffic to allow the level crossing to be secured and a second part-time equal to the time required to secure the level crossing no adjacent intersection would affect the traffic flow.
  • the first part-time begins at the moment when the traffic light system is affected; it ends as soon as the securing of the railroad crossing can begin.
  • a warning signal device for warning motor vehicle drivers before approaching railway vehicles at level crossings railroad without technical assurance known.
  • a constantly active low-power radio station is installed.
  • a transmitter of another low power, variable range radio signal is also installed, activated by the signals of approaching traction vehicles.
  • a receiver of signals from the transmitters at the level crossings are in the motor vehicles, where the received signal generates a warning tone and / or possibly an additional light signal for the motor vehicle driver as a sign that a railway vehicle is approaching the railroad crossing.
  • the patent DE 10 2007 032 091 B3 discloses an apparatus for monitoring a level crossing with a railway line, a road and barriers located on either side of the railway line.
  • the road is divided from the railway track into a first and a second road section, between which there is a danger area.
  • the device comprises in each case two cameras, which are arranged in front of and behind the danger zone and are designed to receive the first and second road sections in first and second viewing directions, respectively, and an electrical control, which is designed to successively take pictures of an object. which approaches the railroad crossing, crosses it and moves away from it again, wherein the recorded images are compared for the recognition of the object.
  • patent documents WO 2004/053813 A1 and WO 00/46775 A1 also disclose a device or system for monitoring a level crossing.
  • the invention has for its object to provide a method and an apparatus of the type mentioned, with the traffic safety at the railroad crossing can be improved.
  • the sub-task related to the method is achieved according to the invention by a method having the features of claim 1.
  • a traffic flow of vehicles in the exit is detected.
  • Typical traffic variables describing the traffic flow are the traffic volume, that is to say the number of vehicles passing a measuring cross section per unit of time, as well as the speed of the vehicles at the measuring cross section, averaged over a predetermined period of time. From the measured traffic variables, it can be determined whether there is free, stagnant or stationary traffic at the measuring cross section. In particular, it is thus possible to determine whether a backflow end of a backlog of vehicles building up in the exit has reached the measuring cross section formed, for example, by a series of induction loops laid in the road surface.
  • the position of a tailback within a detection range can be localized even more accurately. If the tailback end approaches the danger zone of the level crossing in a critical manner, which may be indicated by falling below a predefinable distance threshold between the tailback end and the danger zone, the access road in front of the danger zone is blocked. This blocking can be done by emitting a light signal or other traffic-inhibiting devices. This is to prevent further entry into the danger zone, which could lead to a dangerous growth of the backwater in the danger zone of the railroad crossing and thus to a dangerous situation when approaching a rail vehicle. This provides a simple and inexpensive solution to the security problem.
  • the solution can be independent of technical safety devices of railway operations, the different security classes have to be sufficient as road traffic signal systems designed.
  • the decoupling of road and rail traffic control systems also eliminates the need for coordination.
  • the signaling can be triggered preventively independent of an actual approach of a rail vehicle.
  • an intrusion of the tailback is reported in the danger zone of a traffic signal system, which regulates the traffic at a road junction following the railroad crossing, wherein on the exit before the follower node waiting or incoming vehicles, a release phase is signaled.
  • the message can be wirelessly wireless or wired between the controllers involved.
  • a critical approach of the tailback is reported to the danger area or intrusion of the tailback end in the danger zone of a traffic signal system, which regulates traffic at a road junction preceding the railroad crossing, the traffic at the Vorknoten depending on the location of Backwater is regulated.
  • the traffic flowing in from the preliminary node via the approach to the railroad crossing can be throttled in such a way that the entire amount of traffic flowing out of the preliminary node does not cause a backlog in the exit.
  • penetration of the tailback end into the danger zone is reported to a control center assigned to rail traffic on the railway line. If a vehicle or other object, despite the aforementioned measures, are in the danger zone, can by understanding the railway control center influence on rail transport. Thus, by remote message from the control center, a rail vehicle approaching the railroad crossing can be prevented from continuing or forced to emergency braking to prevent an accident.
  • video images are taken from the exit and evaluated digitally to detect the position of the tailback.
  • image evaluation algorithms in a video camera on the one hand, an object recognition can take place, depending on the result of which additional security measures can be taken, but also recordings for documentation purposes are stored.
  • the video footage can be used to analyze local events and, if necessary, to prosecute deliberate traffic violations.
  • a length of a vehicle approaching the backflow end is determined by digital evaluation of the recorded video images. Depending on the result of the investigation, a passenger car of short length may still be allowed to pass through the danger area while the access for a truck with a trailer is blocked in order to prevent a blockade of the danger area.
  • the related to the device sub-task is achieved by a device performing a method according to one of claims 1 to 6, with a traffic detector, which is adapted to detect the position of the end of forming on the exit backwater of vehicles and falls below a to announce predefinable distance threshold between tailback and danger zone, and with a traffic signal, which is adapted to receive a message from the traffic detector and to control the vehicle traffic in the railroad crossing area via signalers.
  • a road S which connects two adjacent road junctions VK and FK, and a single-track railway line B intersect.
  • a danger area G in which the lanes of the enemy road and overlap rail traffic flows.
  • vehicle backlog can occur in each of the two directions of the road S, but will be described below for vehicles F, which are located on the road S from Vorkknek VK on the access Z to the level crossing BÜ and from there on the Take exit A to the next node FK.
  • a traffic detector 10 preferably a video camera with image evaluation unit
  • the traffic flow - traffic, average speed, occupancy, and the like - and the length of vehicles F on the exit A is detected and closed on the location of an end E of the back-staking vehicle queue .
  • the field of view of the video camera 10 detects the danger area G and an adjoining section of the exit A in order to detect the jam end E or other lying in the danger area G, stationary objects and recognize.
  • the video camera 10 transmits a corresponding message to a control device 11 at the level crossing BÜ.
  • the control unit 11 switches via a signal generator 12 at the level crossing BÜ a blocking light signal for the level crossing BÜ on the approach Z approaching vehicles F. This prevents further vehicles F drive into the danger zone G, which might not leave them immediately. This considerably reduces the collision risk of a rail vehicle with a vehicle F or other object located in the danger zone G.
  • the blocking of the access Z in front of the danger zone G can additionally be supported by lowering a barrier 13.
  • the decision to block access to the danger zone G can be improved.
  • shorter vehicles F can still pass freely, while longer vehicles F, which would extend the backwater into the danger zone G, would be denied entry.
  • the control unit 11 reports a critical backwater on the exit A to a control unit 21 of a traffic signal 20, which regulates the traffic at the sequence node FK.
  • a green phase is requested for the exit F at the following node FK waiting or approaching this vehicle F and initiated with high priority.
  • the accumulated backwater can degrade in order to make it possible for a vehicle F, which has come to a standstill in the danger zone G, to leave the danger zone G quickly.
  • the control unit 11 reports a critical backwater on the exit A and a control unit 31 of a traffic signal system 30, which regulates the traffic at the Vorknoten VK.
  • the signaling via the signal generator 32 can then be dimensioned so that the pre-notes VK leave only sufficiently small vehicle pulse on the access Z, which then cause no critically large
  • control unit 11 reports a stationary object detected in the danger zone G to a control center 40, which can influence a rail vehicle traveling on the railway line B.
  • the rail vehicle can be denied the exit from a station used or it can be caused by signal or remote message to a slow speed or even emergency braking.
