Spacing between bollards can be different depending on where they are installed. To prevent cars from driving between them, do not exceed the spacing more than 5 feet. Bollard spacing can differ for storefronts, campuses, sidewalks, loading docks, around utilities, landmarks and plantings. The distance between bollards should be between 3 feet - 5 feet, enough to allow for pedestrian traffic and wheelchair access (to comply with ADA), but not enough for a vehicle to pass through. Sometimes, bollard spacing depends on traffic flow in the area. If traffic is aggressive, bollards would be placed in close proximity. However, check with local codes and ordinances for correct placement and spacing requirements when planning bollard installations.
