Centerline hardening involves placing durable plastic bollards , flex posts , and / or rubber curbs along the centerline . When used at intersections , they can be effective at requiring motorists to make left-turn movements at a 90-degree angle , thereby slowing vehicle speeds and improving motorists ’ visibility of the crosswalks across which they travel when turning . When used along a roadway segment , they can be effective at generally slowing vehicle speeds and preventing undesirable left-turning and / or U-turns between intersections .

Uses centerline deflection within existing curb by placing vertical barriers ( e . g ., curbs , onstreet parking ) to require vehicle operators to make frequent horizontal movements , which typically reduces vehicular speeds .
