EFFECTS OF REVERSIBLE LANE MOVEMENT SIGNALIZATION OF THREE LANE HIGHWAYS
SINCE THE ARTERIAL, DIRECTIONAL MOVEMENTS DURING PEAK HOURS WERE FOUND TO BE EXCEPTIONALLY UNBALANCED, IT WAS DECIDED THAT GREATEST EFFICIENCY WOULD RESULT FROM A PLAN OF OFF-CENTER LANE, OR REVERSIBLE CENTER LANE MOVEMENT, SIGNALIZATION. ACCORDINGLY, 11 INTERSECTIONS WERE SIGNALIZED AND CONTROLLED BY MASTER EQUIPMENT TO PROVIDE TWO INBOUND LANES DURING MORNING PEAK, TWO OUTBOUND LANES DURING AFTERNOON PEAK, AND TWO-WAY CENTER LANE USE BETWEEN UNBALANCED FLOWS. A COMPREHENSIVE STUDY OF LANE USE, TRAVEL TIME, CAPACITY, OVER-ALL VOLUMES, PARALLEL ROUTE USE, AND DELAY WAS MADE THREE MONTHS BEFORE SIGNALS WERE INSTALLED. A SIMILAR FOLLOW-UP STUDY WAS MADE NINE MONTHS AFTER SIGNALS BEGAN OPERATION. ANALYSES OF THESE STUDIES REVEAL THAT THE SIGNALIZATION HANDLES LARGER VOLUMES, REQUIRES SLIGHTLY LONGER TRAVEL TIME, RESULTS IN MORE ORDERLINESS OF ALL MOVEMENTS, MORE OVER-ALL STANDING DELAY, MORE TRAFFIC ACCIDENTS, LITTLE OR NO DIVERSION TO PARALLEL ROUTES, LIMITED ILLEGAL USE OF LANES, REMARKABLE ACCEPTANCE BY USERS, AND VASTLY IMPROVED PUBLIC RELATIONS. /AUTHOR/
