Transport Assessment

Transportation impacts from all developments which are predicted to generate an increase in traffic must be assessed. A Transport Statement or Transport Assessment should be submitted with a planning application for such a development depending on the scale of the proposals. Some developments may also require a Travel Plan.

We have answered frequently asked questions relating to Transport Assessments:

What is a Transport Assessment?

A Transport Assessment is a detailed assessment of all of the transportation effects of a proposed development. In addition to analysing the effects of increased traffic on the local road network a Transport Assessment identifies measures which will be taken to reduce the severity of these anticipated impacts. Further details of how a Transport Assessment is undertaken are provided below.

What is a Transport Statement?

A Transport Statement is a simplified Transport Assessment which may be used for smaller scale or change of use developments which generate less significant transport impacts. For more information on Transport Statements please visit our Transport Statements page.

When is a Transport Assessment or Transport Statement required?

The National Planning Policy Framework (NPPF) states that “All developments which generate significant amounts of movement should be supported by a Transport Statement or Transport Assessment…”

The magnitude of the predicted transport impact determines the detail of assessment required. Larger developments may require a full Transport Assessment, for smaller developments a Transport Statement may be sufficient.

Consultation with the local authority is recommended in order to agree the type of assessment that will be undertaken. Arcus’ Traffic Engineers have extensive experience in consulting with local authorities and will always aim to ensure that the least onerous type of assessment, which satisfies all policy and guidance, is selected.

What is a Travel Plan?

A Travel Plan is a site specific package of measures which aim to reduce the significance of transport effects from a proposed development and encourage accessibility by sustainable modes. A Travel Plan is generally required to accompany Transport Assessment, and in some instances may be required to accompany a Transport Statement. For more information please visit our Travel Plan page.

What is contained within a Transport Assessment?

A Transport Assessment would generally contain the following:

  • Qualitative and quantitative assessment of exiting conditions including:

– Description of existing site
– Qualitative assessment of existing road and traffic conditions
– Baseline traffic count data
– Active travel assessment
– Public transport accessibility assessment
– Traffic accident data analysis

  • Details of the proposed development including:

– Description of proposed development
– Details of proposed access arrangements
– Details of servicing arrangements
– Qualitative description of anticipated traffic movements during construction and operation
– Quantitative assessment traffic generation during construction and operation utilising TRICS database
– Details of car parking

  • Steps which have been taken to reduce the severity of impact including:

– How sustainable transport modes will be promoted and encouraged by the design of the development
– Improvements which may be made to the nearby transport network in order to reduce the severity of impacts

  • Assessment of the residual impact on the road network including:

– Determination of anticipated modal share and route assignment
– Traffic modelling of road and junction network as required to quantify residual impact

  • Development of mitigation measures which may include:

– Maximising use of sustainable transport to access the development
– Physical improvements to infrastructure
