The intersection of the SW Corridor Park, Tremont St., and Malcolm X Blvd is very bad. There are 8 lanes of traffic coming from 4 different directions to pay attention to, and the crosswalk is the old-fashioned kind that gives no acknowledgement when the button is pressed. Everybody assumes the pedestrian cross request button doesn't work, so nobody ever pushes it, and as a result, pedestrians and bicycles both ignore the light and cross whenever the feel they can. I commute the SW Corridor by bike every day and I can't even count the number of near disasters I've seen at this intersection. It would be dramatically improved if the new crosswalk buttons that have a light and audible confirmation when pressed were installed here. I have noticed that pedestrians and bicyclists are far more inclined to wait for the light at intersections where these devices are used.
