Guidance on Transport Assessment
The National Planning Policy Framework (NPPF 2012) states that all developments that generate significant amounts of movement should be supported by a Transport Statement or Transport Assessment which should be submitted along with a planning application for the proposed development. It will then be used to determine whether the transport impact of the development on transport is acceptable.
Transport Assessments are normally produced by specialist transport planning professionals on behalf of developers and are used by decision makers in the planning process.
The National Planning Policy Framework (NPPF 2012) also states that development should only be prevented or refused on transport grounds where the residual cumulative impacts of development are severe.
Following the withdrawal, in October 2014, of The Department for Transport Document (March 2007) ‘Guidance on Transport Assessment’ guidance on the preparation of supporting documentation in highway assessment terms can be found in the Planning Practice Guidance (PPG) suite of documents and in particular in “Travel Plans, Transport Assessments and Statements in decision taking”. These guidance documents set out the methodology that should be used when undertaking a Transport Assessment and state the importance of entering into early discussions with the Local Planning Authority and other relevant authorities (Local Transport Authority, Local Highways Authority and Highways Agency) to agree the scope of assessment prior to it’s completion and submission as part of a planning application.
Transport Assessments are required for all development proposals that are likely to have a significant impact on the transport network. For developments that are likely to have only a relatively small impact on the transport network, it may be appropriate to provide a Transport Statement instead of a full Transport Assessment and in some circumstances when the transport impact is likely to be minimal then it may not be necessary to provide any formal assessment. Criteria is provided on the Planning Portal. However, the need for, and the level of transport assessment required should be determined in consultation between the developer and the relevant authorities.
Both forms of Transport Assessments should consider the impact of the development on all transport modes, set out proposals to minimise the impact of the development on the transport network and promote measures to encourage sustainable transport. The impact of the remaining development traffic that cannot be reduced further through sustainable transport measures is assessed on the local road network. These assessments take place at the proposed opening year for the development and at a future design year that has been agreed with the Local Authority, which is usually 5-10 years from the date of planning submission, with future traffic forecasts calculated using TEMPro software and adjusted using site specific data if available.
Local Authorities are generally required to ensure that developments which generate significant movement are located where the need to travel will be minimised and the use of sustainable transport modes can be maximised. A key tool to facilitate this will be a Travel Plan. National Planning Policy Framework (NPPF 2012) requires that all developments which generate significant amounts of movement should provide a Travel Plan. A Travel Plan is implemented as part of the development proposals upon occupation and sets out the measures that are proposed to encourage sustainable transport.
