An on-site pedestrian circulation system must be provided, which connects the parking areas and the buildings on the site. The circulation system must be hard-surfaced and be at least five feet wide. Where the system crosses driveways, parking and loading areas, it must be clearly identifiable, through the use of striping, elevation changes, speed humps, a different paving material or other similar material. In order for employees to safely use it at night, the on-site pedestrian circulation system must be adequately lighted.
