Conclusions One-Ways are trivial to implement and are readily reversible – A few one-way signs, some paint, reprogramming of the traffic light at Alex&Univ to activate only for pedestrian Xing requests. Eliminates all turning movement conflicts at Alex&Univ Substantially reduces Wawa Access conflicts & improves access to Dinky Kiss&Ride Only slightly alters existing travel patterns Decreases traffic flow along upper Alexander (Mercer Hill) Better utilizes College Rd by having it absorb some increased traffic; (increased from essentially zero) Adds only few left turning movements from Univ to College Rd. Adds a little more traffic on upper Univ which can be readily handled by the light at Univ&Nassau
