How to Write a Site Traffic Management Plan That Actually Gets Followed
Plant-pedestrian contact remains one of the most common causes of serious site injury. A traffic management plan (TMP) that sits in a folder and doesn't match what actually happens on the ground is worse than useless — it gives a false sense of assurance. Here's the process for building one that reflects real site movement and gets enforced.
On-page checklist
- Current vehicle and plant movement mapped by direct observation
- Every pedestrian-vehicle crossing point given a named control
- Reversing manoeuvres minimised and controlled where unavoidable
- Zone-specific speed limits set from actual sightlines
- Review trigger tied to layout change, not just calendar date
- Routes briefed physically at induction and toolbox talk
The step-by-step process
1. Map actual vehicle and plant movements first
Before drawing routes on paper, walk the site during a working period and note where plant, delivery vehicles and pedestrians actually cross paths — not where the site plan assumes they should.
2. Identify every pedestrian route that crosses a vehicle route
Each crossing point is a hazard that needs a specific control: a marked crossing, a banksman, physical segregation, or a scheduled 'plant stop' window.
3. Set one-way systems and turning areas
Reversing remains a leading cause of plant incidents. Design routes to minimise reversing manoeuvres, and where reversing is unavoidable, mandate a banksman or reversing-camera/alarm combination.
4. Segregate pedestrians physically wherever the site allows
Barriers, kerbs or demarcated walkways are more reliable controls than signage alone. Reserve signage-only segregation for low-risk, low-traffic areas.
5. Set speed limits appropriate to sightlines, not a blanket number
A 10mph yard limit may still be too fast on a blind corner with stacked materials. Set limits per zone based on actual sightlines and pedestrian density.
6. Build in a review trigger, not just a review date
A TMP should be reviewed whenever the site layout changes materially — new compound, new delivery point, phase change — not just at a fixed calendar interval.
7. Brief it at induction and toolbox talk, not just issue it as paperwork
Every operator and pedestrian needs to physically walk or be shown the live routes, crossing points and any temporary changes, not just sign that they've read the document.
Common failure points
- A TMP drawn up once at project start that no longer matches the site months later
- Crossing points marked on paper with no physical control on the ground
- Reversing treated as routine rather than a specific hazard requiring a banksman or camera system
- Induction sign-off treated as evidence that people understand and follow the routes
What good looks like
- A TMP drawing that matches what you'd actually observe walking the site today
- Every pedestrian-vehicle crossing point named with a specific control, not a generic 'take care' note
- Operators and site staff able to describe the current routes and crossing points when asked, not just recall signing a document
- A visible trigger process for updating the plan when the site layout changes
FAQs
Who should write the site traffic management plan?
Typically the site manager or a competent person appointed under CDM 2015, often supported by the principal contractor's health and safety advisor, but it must reflect real, observed site conditions rather than being drafted from a desk.
How often should a traffic management plan be reviewed?
Whenever the site layout materially changes — a new compound, phase, delivery point or plant type — in addition to any fixed periodic review your management system requires.
Do banksmen need specific training?
Yes — banksman and slinger duties require specific competence in signalling, exclusion zones and safe positioning; see our banksman/slinger training course.
Does a small yard need a formal traffic management plan?
Any site with plant and pedestrians sharing space benefits from a documented plan, even a simple one-page version — the PUWER and CDM duty to control workplace risk applies regardless of site size.
