Sharon Valley Road Roundabout

Sharon Valley Road will be closed at the intersection with Evans Boulevard and the access road to The OSU/COTC campus, beginning Monday, June 5th until Wednesday, August 16, 2017, for the installation of a roundabout. Motorists will need to use an alternate route during the closure.

***Access to the Legend and Liberty schools will be maintained by a temporary access driveway accessible from the TJ Evans athletic complex parking lot.

 

WHAT IS A ROUNDABOUT?

•       CIRCULAR INTERSECTION (70-180 FEET DIAMETER)

•       GEOMETRY PROVIDES DEFLECTION TO SLOW SPEEDS (~15-20 MPH)

•       ENTERING VEHICLES YIELD TO CIRCULATING TRAFFIC

•       CIRCULATING TRAFFIC HAS RIGHT OF WAY

•       SPLITTER ISLANDS

•       DEFINED TRAVEL PATH

BENEFITS OF ROUNDABOUTS1:

•      35% REDUCTION IN TOTAL CRASHES

•      76% DECREASE IN INJURY CRASHES

•      81% REDUCTION IN FATAL CRASHES

•      30-40% DECREASE IN PEDESTRIAN CRASHES

1Compared to Signalized Intersections, as published in NCHRP Report 572, Roundabouts in the United States, Transportation Research Board, 2007

 

WHY ARE THEY SAFER?

•      SEVERE CRASH TYPES NEARLY ELIMINATED

•      (NO HEAD-ON, ANGLE, AND LEFT TURN CRASHES)

•      FEWER CONFLICT POINTS (VEHICLES AND PEDESTRIANS)

•      (LESS CONFLICT = LESS CRASH POTENTIAL)

•      VEHICLE SPEEDS ARE REDUCED THROUGH GEOMETRY

•      (SLOWER SPEEDS = DECREASE IN CRASH SEVERITY)

•      SHORTER PEDESTRIAN CROSSING WIDTHS

•      (LESS TIME IN STREET = LESS POTENTIAL FOR CRASH)

•      NO ABILITY TO SPEED UP TO “BEAT THE LIGHT”

•      NO RED LIGHT RUNNING

•      DRIVER’S ATTENTION FOCUSED ON ROADWAY, NOT UP AT TRAFFIC SIGNALS

 

HOW TO DRIVE SINGLE LANE ROUNDABOUTS:

•      YIELD TO PEDESTRIANS AT THE ENTERING CROSSWALK

•      YIELD TO TRAFFIC INSIDE THE ROUNDABOUT (LOOK LEFT)

•      YIELD TO PEDESTRIANS AT THE EXITING CROSSWALK
