THE PROBLEMS OF CALCULATING RESPONSE INTERVALS FOR FLASHING LIGHTS (AND GATE PROTECTION) AT RAILWAY GRADE CROSSINGS

The length of the response interval for flashing light signals to be activated depends upon the approach time of the highway vehicle, the speed of the train, and the relationship between certain signalling and operational conditions. Since safety requires the assumption of the fastest train when calculating the response interval, slower trains and trains that come to a stop before reaching the crossing impose longer waiting times, and cause annoyance to the highway users. This can be avoided by having the response made sensitive to the speed of the train, which will cause the response interval to be adjusted accordingly. This article describes this system, presenting mathematical equations, charts and tables of the data.
