One-way traffic systems reduce the risk of head-on collisions between vehicles on construction sites. Poorly managed site traffic is a leading cause of fatalities in the UK construction industry. Every operative must understand how one-way routes work, where they apply, and what to do when routes change. This talk covers the key principles of one-way site traffic management.
Key Hazards
Head-on collision between vehicles on narrow haul roads
Pedestrians struck by vehicles travelling in unexpected directions
Confusion at junctions where signage is missing or unclear
Vehicles reversing against the one-way traffic flow
Control Measures
Establish clearly signed one-way routes using directional arrows and signage at all entry and exit points.
Segregate pedestrian walkways from vehicle routes with physical barriers where practicable.
Brief all drivers and operatives on the current traffic management plan before starting work.
Install speed reduction measures such as chicanes and speed bumps at key turning points.
Use banksmen at blind junctions and areas where visibility is restricted.
Review and update the traffic management plan whenever site layout changes.
Ensure adequate lighting on all one-way routes, especially during winter months and night shifts.
Prohibit reversing except in designated turning areas with banksman control.
Display the current site traffic plan on notice boards and at site entrances.
Remember
One-way systems prevent head-on collisions and keep site traffic flowing safely
Always follow the signed route even if a shortcut seems quicker
Report any missing or damaged traffic signs to your supervisor immediately
Pedestrians must use designated walkways and never walk along vehicle routes
Reversing is only permitted in designated areas with banksman assistance
Check the traffic plan daily because routes may change as work progresses
