RSA-Not enough time to get through traffic lights at rail crossing intersections-RESPONSE
We contacted the City of Portland and received this response: “Our amber times are based on the safe stopping distance for the speed of the approach and grade. When amber times are increased beyond the normally calculated times, driver behavior changes and more drivers push the amber, having learned that the time has increased. We have a 3 second amber at Jefferson and Columbia which is consistent with most of the signals in the CBD. There is an additional second of all red prior to the opposing vehicle or train getting the green or solid white bar after the side street amber.” The duration of the light will not be changed at this time, based on concerns about driver behavior.
