Factors such as pedestrians, traffic control, turning restrictions, and traffic volumes will affect the design of parking facilities, particularly the location of entry and exit points. As illustrated above, a minimum driveway turning radius of 20 feet is recommended. A driveway width of 25 feet is recommended for two-way traffic flow. Try to locate driveways at least 200 feet from intersections, particularly for larger traffic generators. A qualified engineer should determine the exact spacing and location of access points. When designing access points to parking lots, be sure to use the same design standards for signing and pavement markings as are used for adjacent roadways.
