The new flashing yellow light signal that is activated immediately by pushing a button is better than the random crosswalk that isn't at an intersection. However by allowing the signal to be activated whenever a pedestrian wants to cross the street means that it isn't timed with the light at the intersection at S Shirlington Rd and S Arlington Mill Dr. Therefore when someone activates the signal right as the light turns green the traffic cannot move and the road backs up.
Is it possible to force the signal to be timed with the intersection lights?
