The information provided in this memo <br />is information obtained from NCHRP 672: Roundabouts an Information Guide, 2nd Edition and <br />from my own personal experience designing and implementing roundabouts over the past <br />decade. <br /> <br />There are four main aspects that make pedestrians crossings at roundabouts safer than <br />traditional intersections: <br />1. Reduction of conflict points <br />2. Crossing one direction of traffic at a time <br />3. Shorter crossing distance <br />4. Driver multi-stage recognition <br /> <br />Reduction of Conflict Points: <br /> <br />A conflict point is any time two paths of a vehicle or pedestrian cross. Roundabouts reduce the <br />number of vehicle to vehicle conflict points from 32 to 16. They also reduce the number of <br />vehicle to pedestrian conflicts from 16 to 8. A pedestrian that is crossing at a standard <br />intersection not only has to cross multiple lanes at one time, they also have to know where the <br />vehicles are coming from that might be crossing their path. This includes vehicles to the left, <br />right, across from the pedestrian and behind the pedestrian. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />
