What about the other seemingly ridiculous situation of multiple sets of lights - sometimes just a few metres apart?
Perfect example on Davitt Road at the Goldenbridge Luas stop - a set of pedestrian lights with a set of junction lights only about 20 metres further on - often in conflict with eachother.
In an effort to make it 'clearer' for drivers, in someone's wisdom, a shield has been fitted over the green light on the citybound set at the junction, making it difficult to see unless you have passed through the pedestrian lights and, in my opinion, making it uncertain as to whether the light is functioning or not.
Why didn't they just move the junction line back 20-metres to the Luas stop?
Further examples of multiple sets of lights short spaces apart and at odds with the road layout and eachother are on the Rathfarnham Road above Terenure, Stoneybatter and Knocklyon near Superquinn.
Anyone got other examples of where traffic lights are springing up places that make you say 'why are the lights located here?'
