    • Intersec;on  Design  
    • Principles  of  Good  Intersec;on  Design  •  Compact  •  Avoid  conflicts  •  Simple  right-­‐angle   intersec/ons  are  best  •  Avoid  free-­‐flowing   movements  •  Apply  access   management  principles  •  Signal  /ming  considers   all  users  
    • Universal  Access  
    • Sidewalk  Zones  Single-­‐Family  Residen;al    
    • Pedestrian  Crossings  
    • Principles  of  Pedestrian  Crossings  •  Safe  crossing  is  a  must   •  Don’t  compromise  safety  •  Consider  all  users   to  accommodate  traffic   flow  •  Meet  accessibility   standards  and  guidelines.   •  Design  begins  with   appropriate  speed.  In  •  Crossings  must  be   general,  urban  arterials   “comfortable”   should  be  designed  to  a  •  Use  treatments  with   maximum  of  30  mph  or   highest  crash  reduc/on   35  mph   factors     •  Every  crossing  needs   tailored  design    
    • Design  Considera;ons  •  Ideally,  uncontrolled  crossing   •  Double  (or  triple)  le`  or  right   distances  should  be  no  more  than   turns  concurrent  (permissive)   21  feet.  Streets  wider  than  40   with  pedestrian  crossings  at   feet  should  be  divided  by   signalized  intersec/ons  must   installing  a  median  or  two   never  be  allowed.     crossing  islands.     •  Avoid  concurrent  movements  of  •  Maximum  of  three  lanes  per   motor  vehicles  and  people  at   direc/on  on  all  roads  (plus  a   signalized  intersec/ons.   median  or  center  turn  lane).   •  People  should  never  have  to  wait  •  There  must  be  a  safe,  convenient   more  than  90  seconds  to  cross  at   crossing  at  every  transit  stop.   signalized  intersec/ons.   •  Pedestrian  signals  should  be   provided  at  all  signalized   crossings  where  pedestrians  are   allowed.
