Several driveway designs may cause safety and access problems for pedestrians,
including excessively wide and/or sloped driveways, driveways with large
turning radii, multiple adjacent driveways, driveways that are not well
defined, and driveways where motorist attention is focused on finding
a gap in congested traffic. In addition, driveways without a level sidewalk
landing may not comply with ADA standards. Refer to Chapter 5 in Designing
Sidewalks and Trails for Access, Part II of II: Best Practices Design
Guide for further guidance.1
Examples of driveway improvements include narrowing or closing driveways,
tightening turning radii, converting driveways to right-in only or right-out
only movements, and providing median dividers on wide driveways.
When driveways cross sidewalks, it is necessary to maintain a sidewalk
level across the driveway of no more than 2 percent sideslope (see sketch).
This is more usable for all pedestrians, especially those in wheelchairs,
and makes it clear to motorists that they must watch for pedestrians.
It is important to minimize large signs and bushes at driveways to
improve the visibility between motorists and pedestrians. The sidewalk
material (usually concrete) should be maintained across the driveway
