Traffic lights?

Running Bing

Whats the deal with traffic lights today? When I press the button does it actually make it light any quicker or are they just for blind people crossing the road? I remember they used to have the old traffic lights where you'd press a button and wait would come up but the new ones dont seem to make a difference. Also I notice its nearly always only old people who actually press it. So should I be pressing the button or are they just for blind people.

Depends on the location, I'm pretty sure in the likes of DCC most are optimized for smooth traffic flow, both motorized and pedestrian. Where as the single set of traffic lights in Cavan town do nothing unless the button is pressed, upon which they turn red within seconds.

Push the button. The WAIT sign is a thing of the past - just wait for the double-time beeps and you can cross safely

Like Mirror says - depends on the location. Some pedestrian lights allow for pedestrian traffic all the time (in a city for example) others work on an 'on demand' basis.
