18) Avoid striping crosswalks at unsignalized <br />intersections with inadequate sight distance. <br />Either mitigate the inadequate sight distance or <br />direct pedestrians to alternative crossing loca- <br />tions. Minimum intersection sight distance is <br />based on local, state, or AASHTO guidelines. <br />19) If a raised median nose extends into the <br />crosswalk, provide an ADA -compliant channel <br />through the median. <br />20) Use local, state, or AASHTO guidelines to <br />determine decision and stopping sight distance <br />triangles at uncontrolled and stop controlled <br />intersections before striping a crosswalk. <br />21) Provide illumination for intersections with <br />striped crosswalks. <br />22) Signal timing for pedestrians shall be based <br />on MUTCD standards. <br />23) Provide signal heads (Walk/Don't Walk) at <br />all signalized intersections, except where <br />pedestrian movements are prohibited. <br />Push buttons at signalized crossings improve <br />conditions for pedestrians <br />_: <br />Curb ramps improve street access for those <br />who use wheelchairs <br />24) Provide pedestrian pushbuttons at all vehicle <br />activated signals except where pedestrian <br />movements are prohibited. <br />25) Provide pedestrian pushbuttons and signal <br />heads on median refuges at signalized intersec- <br />tions where median refuges are used. <br />26) Provide ADA -compliant wheelchair ramps <br />(two per corner) at all intersections. <br />
