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
