There should be enough visibility at junctions and bends to allow drivers and pedestrians to see anything that might be dangerous.
Avoid sharp or blind bends on vehicle routes wherever possible. Where you cannot avoid them, you should consider measures such as mirrors to help drivers and pedestrians see what is around the corner.
When visibility at a bend or junction cannot be improved, stop signs or signals may be appropriate. It may be necessary to prevent people from using the junction or bend altogether by enforcing a one-way system, or even blocking the road.
Limiting the speed that vehicles move around the workplace is a very important part of controlling traffic.
Using fixed features, for example: humps, narrowed routes (by bollards, raised kerbs, chicanes, built-in routeside features and so on – these are sometimes known as ‘pinch points’), and ‘rumble’ devices (such as rumble strips, rumble areas or jiggle bars).
Humps should be repeated at intervals along a route and should not be used where FLTs operate or within 15 m of a junction or bend.
Speed limit signs may need to be repeated around the site roads instead of just one sign being put up at the entrance to a limit area.
The humps themselves should also be clearly marked.
Sometimes speed cushions can be used instead of speed humps. Speed cushions work in a similar way as speed humps, but do not stretch across the whole road. Instead, they leave some space clear for certain types of vehicle to drive through or straddle the raised areas (for example, cyclists or larger emergency vehicles). See Figure 13.
Protective barriers to keep vehicles away from pedestrian areas.
Where needed, you should provide suitable barriers or guard rails at the entrances and exits to buildings; at the corners of buildings; and to prevent pedestrians from walking straight onto roads.
Protective barriers should be built to the standards set out in BS 7669-3: 1994 Vehicle restraint system. You should read the British Standards= Code of Practice BS 6180: 1999 Barriers in and about buildings for more information.
