We prepare baseline transport data summaries to establish a clear and accurate picture of existing conditions around a site. This includes traffic flows, network performance, accessibility and travel patterns, providing the foundation for proportionate and defensible transport advice.
A robust baseline ensures that future assessment, design and mitigation are grounded in defensible evidence of current conditions rather than assumption.
What is baseline transport data?
Baseline transport data describes how the transport network currently operates before development is introduced. It provides the reference point against which change is assessed and is a critical component of feasibility studies, Transport Assessments, Transport Statements and technical notes.
Baseline data may draw on new surveys, existing datasets or a combination of both, depending on the site and stage or size of development.
Our baseline transport data summaries are tailored to the site and typically include:
-
Review of surrounding highway network and junctions
-
Summary of existing traffic flows and patterns
-
Identification of peak periods and network sensitivity
-
Review of collision and highway safety data
-
Overview of walking, cycling and public transport provision
-
Review of local parking conditions where relevant
-
Summary of constraints and key characteristics
-
Clear visual and written presentation of findings
The value of robust baseline transport data lies in providing a clear and agreed starting point for all subsequent transport work. By establishing how the network currently operates, we help clients understand whether observed issues are existing or development-related and ensure that future assessment is proportionate and focused. A strong baseline reduces the risk of misinterpretation, challenge or over-assessment, and provides confidence to planning authorities that conclusions are based on a sound understanding of existing conditions.
When baseline transport data is needed
Baseline transport data is commonly prepared:
-
At feasibility or pre-purchase stage
-
Prior to transport assessment or modelling
-
As part of pre-application submissions
-
To support Local Plan or site promotion work
-
When updating or supplementing historic data
-
Where existing conditions are complex or sensitive
Early baseline clarity supports smoother progression through planning.
Our approach
We take a clear, proportionate approach to baseline data preparation:
-
Review the site context and surrounding network
-
Identify the data needed to understand existing conditions
-
Collate and summarise survey and published data
-
Interpret findings using professional judgement
-
Present baseline conditions clearly and concisely
Our focus is on producing baseline summaries that are useful, defensible and easy to understand.
Who we support
We prepare baseline transport data for:
-
Residential and mixed-use developments
-
Commercial and employment sites
-
Education and healthcare projects
-
Energy and infrastructure schemes
-
Strategic land and Local Plan promotion
Our experience across England, Scotland and Wales ensures baseline data is aligned with local authority expectations.
