R3 is calculated using R2 or R4 speed + acceleration to crosswalk. <br />2. Relative Speed Differential is from minimum speed (typically R4) within roundabout. <br />according to NCHRP Report 672: Roundabouts an Informal Guide: Second Edition <br />3. Relative Speed Difference should be in the range of no more than 10 - 15 mph, Date: Printed:WSB Filename:K:\011498-000\Cad\Exhibits\ICE\F7 - Fast Path Analysis.dgn10/8/2018 <br />County Road E at Old Snelling Ave <br />ICE Report|Arden Hills, MN <br />N N
