Device for traffic-dependent control of barriers and light signals at a grade crossing
In a method for traffic-dependent output of a control signal for at least one of a barrier and a traffic light signal at a grade crossing, a radar sensor device detects motions of traffic objects over a street traffic area of the grade crossing, a control signal is emitted to a control unit for the barrier and/or for the traffic light signal situated on the inflow side of the grade crossing, using a lead time before an expected time of arrival of a train at the grade crossing, and the lead time is determined with the aid of a curve over time of the detected motions of the traffic objects, the lead time for a slow-moving traffic being greater than for a more rapidly flowing, unimpeded traffic.

Method For Commanding A Railway Level Crossing Protection System
A method for commanding a railway level crossing protection system comprising: a) activating a railway signal preventing a train from driving beyond a level crossing; b) detecting an incoming train approaching the level crossing and measuring a speed of said incoming train; c) calculating a waiting time, as a function of the train's measured speed; d) waiting until expiration of the calculated waiting time and, once said waiting time expires, sending an order to commute the protection system into the protected state; and e) querying the state of the protection system and if said protection system is found to have commuted into the protected state, deactivating said railway signal, and maintaining said railway signal in the activated state otherwise.
Train simulator test set and method therefor
A train simulator test set is disclosed that can be operably coupled to a railroad track to measure the resting impedance of that track circuit and simulate a train by varying the railroad track inductance over a set period of time. The test set can select the speed, direction, and number of trains to simulate. By applying a variable inductance on the railroad tracks, the test set can simulate a train moving at variable speeds toward and away from the island. The test set can apply inductances to the railroad tracks to simulate two or more trains moving in each direction of the tracks at the same time, along with multiple looks and routes. The train simulator test set can include simulation software to vary the parameters of the train simulation and couple a variable inductance on the railroad tracks.
Modular railroad track simulator
A system for simulating a railroad track. The system comprises one or more modular track simulation units that are smaller than conventional track simulators and are easy to use with and be connected to a device being tested (e.g., grade crossing predictor). Each track simulation unit may have one of a plurality of impedances associated with a corresponding railroad track length. The units are combinable such that the system can simulate multiple, different track lengths. Each unit has a plurality of test points that can be connected to the device under test and/or used to alter conditions of the simulated track.
