Traffic management plans for mobile plant: how to build one that works
A traffic management plan sets out how vehicles, plant and pedestrians move around a site without meeting in the wrong place. On sites with excavators, dumpers, telehandlers and delivery lorries, it is the single document that does most to prevent people being struck or crushed.
The plan does not need to be long. It needs a clear drawing, a few firm rules and someone responsible for keeping it current as the site changes. A plan that was right in week one and never updated is one of the most common findings after an incident.
Logan Plant Training covers traffic management in its one-day Managing Mobile Plant course, delivered on the customer's own site so the plan can be discussed against real routes.
Key points
- Separate pedestrians and plant physically wherever you can.
- Design out reversing before relying on banksmen.
- Show routes, crossings, loading areas and exclusion zones on one drawing.
- Brief everyone, including delivery drivers and visitors.
- Review the plan whenever the site layout changes.
The legal basis
On construction sites, CDM 2015 requires the site to be organised so pedestrians and vehicles can move safely, with suitable traffic routes. In other workplaces, the Workplace (Health, Safety and Welfare) Regulations 1992 require traffic routes to be organised similarly. HSE guidance HSG144 sets out practical measures for vehicles on construction sites.
None of this prescribes a format. What matters is that the plan fits the site and is actually followed.
What to put on the drawing
Start with a site plan and mark the vehicle entrance and exit, pedestrian entrance, haul routes, one-way systems, crossing points, parking, loading and unloading areas, plant working zones and any overhead or underground hazards. Use colour so the separation is obvious at a glance.
Mark where plant turns and where reversing cannot be avoided. Those are the places that need the strongest controls.
- Separate vehicle and pedestrian gates
- Barriered walkways along haul routes
- Marked crossing points with good visibility
- One-way loops to remove reversing
- Defined exclusion zones around working plant
Controls in order of effectiveness
Removing the need for vehicles and people to share space comes first. Then physical segregation with barriers. Then procedural controls such as timed deliveries and banksmen. Warning devices, cameras and hi-vis help, but they support the plan rather than replace it.
Banksmen are useful but should not be the default answer to a layout problem. If reversing can be designed out with a turning area or one-way loop, do that.
Deliveries, visitors and changing layouts
Delivery drivers are often unfamiliar with the site. Give them the rules before they arrive, meet them at the gate and guide them to a defined unloading area. Visitors should be escorted or kept to marked routes.
Every time an excavation opens, scaffold goes up or a new phase starts, the routes change. Name the person responsible for updating the plan and re-briefing the team.
Checking it works
Walk the routes regularly and watch what people actually do. Worn paths across barriers or plant cutting corners are signs the plan does not match how the site works, and the plan should change rather than the problem being ignored.
Record near misses involving vehicles and use them to adjust the layout.
Traffic management controls from most to least effective
| Control | Example |
|---|---|
| Eliminate | Deliver materials to a point outside the working area |
| Segregate | Barriered walkways and separate gates |
| Design out reversing | One-way loops and turning areas |
| Procedural | Timed deliveries, banksmen, permits |
| Warning aids | Cameras, sensors, alarms, hi-vis |
Frequently asked questions
Is a traffic management plan a legal requirement?
The law requires traffic routes to be organised safely. A written plan is the normal way to show that on a plant site.
Who should write the plan?
Someone who understands the site and its plant, usually the site manager or supervisor, with input from operators.
How often should it be reviewed?
Whenever the layout or activities change, and at regular intervals.
Does Logan train supervisors on this?
Yes, within the one-day Managing Mobile Plant course delivered on your site.
