4 The plan views shown are for turn lane taper shapes and dimensional purposes only, they do not prescribe the use of curb, curb and gutter, shoulders nor separators specifically to either rural or urban conditions. 2. Total deceleration distances must not be reduced except where lesser values are imposed by unrelocatable control points. 3. right turn lane tapers and distances identical to left turn LANES under stop control conditions. right turn lane tapers and/or distances are site specific under free flow or yield conditions. 4. These left turn configurations apply to continuous left turn LANES only where specifically called for in the plans. 5. For pavement markings see Index No.
5 50 Taper 100 URBAN CONDITIONSRURAL CONDITIONS1. Basis for turn lane configurations: Informed Driver. Stop condition (With Or Without Stop Control). Wet Pavement. Reaction preceeding entry point. Minimum braking distance for urban conditions. 75 min. for L . Comfortable deceleration rates for rural conditions (AASHTO 2001 threshold rate of ).The length of taper may be increased to L for single left turns and L for double left turns when: a. Left turn queue vehicles are adequately provided for within the design queue length. b. Through vehicle queues will not block access to left turn lane. c.
