<br />Vertical Elements <br /> <br />Full! Diagonal Diverter <br /> <br />Purpose <br />A full diverter, sometimes called a <br />diagonal diverter, is a raised barrier <br />place diagonally across an intersection <br />that physicaliy divides the intersection <br />and forces al traffic to make a sharp <br />turn. <br /> <br />~ <br /> <br />Ian <br /> <br />to <br />--~-- <br /> <br /> <br />i:C) <br />--.----.- <br /> <br />~ ld~5d <br /> <br />:Source: Institute ot I ransportatlon I::.ngmeers I raTtlc <;almmg: ~tate of <br />Practice <br /> <br />Effects <br />Volumes May decrease traffic volumes <br />Speed May reduce speed <br />Traffic Noise and Air Little or no effect <br />Traffic Safety Possible improvement <br />Advantages . Reduces traffic volumes <br /> . Restricts vehicle access while maintaining bicycle and pedestrian access <br />Disadvantages . Prohibits or limits access and movement <br /> . Restricts access for emergency vehicles <br /> . May impact drainage <br /> . May impact parking <br />Problems Targeted . Cut through traffic <br /> . Speed - forces driver to slow to make the turn <br />Design . The curvature of the diverter is dependent on the intersection roadway 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 />APRIL 2005 <br /> <br />34 <br />
