E . Raised Crosswalks
Raised crosswalks are applicable for busy streets with multiple lanes . They are similar to speed tables and typically wider than a speed humps . Raised crosswalks are appropriate at some intersections , mid-block crossings , and drop-off and pick-up zones for high pedestrian traffic generators , such as schools , parks , libraries , and airports . Raised crosswalks are typically marked with high visibility pavement markings , signage , lights , and may be surfaced with special pavement material . Raised crosswalks can directly reduce motorist speeds and increase the occurrence of motorists yielding to crossing pedestrians . Marked crosswalks on both sides of a street allow for better visibility of crossing pedestrian zones by motorists ( Figures 7.9.14 and 7.9.15 ).
Design Criteria :
• Surface should be smooth and a different paving and color than the road to enhance pedestrian safety and visibility .
• Pavers or pavement sections shall meet local , state , and federal load-bearing standards .
• To ensure crosswalk visibility , crosswalks must be marked with reflective lines ; high visibility markings are best .
• Proper signage and pavement marking are required in advance of raised crosswalks .
• Refer to the City of Arlington Design Criteria Manual for Crosswalk Standards .
• Evaluate storm drainage and utility locations prior to design and installation of raised median or crosswalks .
• Paving materials are important to the function and look of a street , both in the road and on the sidewalk . Occasionally , paving materials in and of themselves act as a traffic-calming device ( e . g ., when the street is paved in brick or cobblestone ). These materials are however noisy and unfriendly to bicyclists , pedestrians , or wheelchairs . In particular , cobblestone should not be used in the expected bicycle path , although they may be used as aesthetic elements in a streetscape design . Smooth travel surfaces are best for all pedestrians .
• Utilize a concrete paver or natural stone paver with sufficient load-bearing strength .
