Do LEDs make rail better?

March 2010 | David Bruijn, Henk Frieling, Richard Weide

This paper describes the application of LEDs in railway signals. These light sources are traditionally equipped with incandescent light bulbs but LEDs are different in their light characteristics. The driver’s task needs to be considered in order to redesign the signal in such a way that it performs in the same way, or better. A human factors specialist can assist in this. The benefits will outweigh the cost of the advice.
