Full / Diagonal Diverter <br />Vertical Elements <br />Purpose <br />A full diverter, sometimes called a diagonal <br />diverter, is a raised barrier place diagonally <br />across an intersection that physically <br />divides the intersection and forces al traffic <br />to make a sharp turn. <br />Source: Institute of Transportation Engineers <br />Traffic Calming: State of Practice <br />Effects <br />Volumes <br />May decrease traffic volumes. <br />Speed <br />May reduce speed. <br />Traffic Noise and Air <br />Littleor no effect. <br />Traffic Safety <br />Possible improvement. <br />Advantages <br />• Reduces traffic volumes. <br />• Restricts vehicle access whilemaintaining bicycle and pedestrian access. <br />Disadvantages <br />• Prohibits or limits access and movement. <br />• Restricts access for emergency vehicles. <br />• May impact drainage. <br />• May impact parking. <br />Problems Targeted <br />• Cut through traffic. <br />• Speed – forces driver to slow to make the turn. <br />Design <br />• The curvature of the diverter is dependent on the intersection roadway <br />widths. <br />• Special care needs to be taken with drainage design. <br />• The intent is to divert traffic to arterial and collector streets. <br />• Needs to be good visibility approaching the diverter for drivers to react and <br />navigate the turn safely. <br /> <br />
