We undertake swept path analysis to demonstrate that vehicles can safely and practically access, manoeuvre within and exit a site. Our work tests real vehicle movements against proposed layouts, ensuring access, servicing and emergency arrangements are workable and compliant with highway authority expectations.
Swept path analysis is a critical component of access design and is frequently required to support planning applications and highways approvals.
What is swept path analysis?
Swept path analysis uses vehicle tracking software to simulate how different vehicle types move through access points, junctions and internal layouts. It is used to test whether vehicles can manoeuvre safely without conflict, overrunning or reliance on unrealistic assumptions.
Swept path analysis is commonly required for refuse vehicles, delivery vehicles, emergency vehicles and HGVs, and is typically required by Local Highway Authorities, National Highways and other consultees to demonstrate safe movements at junctions without conflict.
Our swept path analysis is tailored to the site, proposal and vehicle requirements and typically includes:
-
Selection of appropriate design vehicles
-
Vehicle tracking at site access points
-
Swept path analysis within internal layouts
-
Assessment of turning areas and servicing arrangements
-
Iterative testing of layout refinements
-
Testing of Abnormal Indivisible Load (AIL) vehicles
-
Clear swept path drawings and written commentary
The value of robust swept path analysis lies in confirming that layouts work in practice, not just in theory. By testing real vehicle movements early, we help clients avoid access arrangements that appear acceptable on plan but fail operationally. This reduces the risk of late-stage redesign, highway objection or operational issues once a site is built. Clear, defensible swept path evidence also provides confidence to highway authorities that servicing, refuse and emergency access have been properly considered and can be accommodated safely.
When swept path analysis is needed
Swept path analysis is commonly undertaken:
-
To support planning applications
-
For new or altered site access
-
Where servicing or refuse access is critical
-
For constrained or tight layouts
-
To support dropped kerb or crossover approvals
-
As part of post-application design refinement
It is particularly important where large vehicles interact with public highways or sensitive internal layouts.
Our approach
We take a clear, practical approach to swept path analysis:
-
Understand the development layout and access strategy
-
Agree appropriate design vehicles with the client or authority
-
Undertake proportionate vehicle tracking
-
Identify conflicts and test refinements
-
Present clear drawings and advice to support approval
Our focus is on realism, clarity and producing outputs that directly support decision making.
