Intersections that intersect at a skewed angle or angle notably <br />different than 90-degrees have a greater likelihood of collisions. <br />Squaring up the intersection helps reduce the likelihood of <br />collisions. “Squaring up” an intersection as close to 90 degrees <br />as possible involves intersection reconstruction and approach <br />realignment to provide better visibility for all road users, also <br />reducing high speed turns, reducing length exposure for vehicles <br />and/or bikes passing through the intersection, and reducing <br />pedestrian crossing length. <br />Cost $$$ <br />Low Cost / Quick Build alternative available <br /> <br />INTERSECTIONS & ROADWAYS <br />Increase <br />Attentiveness <br />and Awareness <br />SAFE SYSTEM HIERARCHY <br />Remove Severe <br />Conflicts <br />Reduce Vehicle <br />Speeds <br />Intersection Reconstruction <br />and Tightening <br />Tier 1 Tier 2 Tier 3 Tier 4 <br />Lane narrowing reduces the width of the marked vehicle lanes to <br />encourage motorists to travel at slower speeds.
