Long 3 minute light; Controls one way traffic; Wait for green
The traffic light mentioned here controls traffic on a one-lane road in a rural area in Pennsylvania. I could see that something would probably need to be posted about the hazard here, since after waiting three minutes, drivers might think the light was broken and go. However, I would consider instead using a pedestrian countdown signal, especially since newer models can be installed without being programmed. There is only one problem with that idea -- if this light is 3 minutes long, then a pedestrian countdown signal would be inadequate since it could only display "99" and not the "180" seconds that the light would take to cycle.
