Ambitious growth plans for the Cambridge sub-region and the wider area, mean there is an increasing demand for accurate evaluation of the impact of proposed developments on the transport network.

To help developers and other organisations predict these impacts, Cambridgeshire County Council is making its sophisticated computer modelling systems available as part of a new transport planning service.

Based on reliable and accepted information, the council’s models are tested and updated and can provide significant savings in time and costs over sourcing similarly robust and relevant data elsewhere.

The new service includes:

Cambridge Sub-Regional Model (CSRM)

  • a comprehensive, multi-modal, interactive land use and transport model which enables the assessment of the wider impact of growth strategies, local plans and development proposals
  • used to assess potential transport implications of large scale developments such as Northstowe and Alconbury


  • simulation traffic assignment model that can be integrated with CSRM
  • corridor and town-wide road network models
  • as used in Ely and St Neots

Local micro-simulation traffic models

  • localised assessment of parts of the Cambridge and market town transport networks
  • as used in Chequers Court, Huntingdon; Ely level crossing

Consultancy, advice and management

  • provided by experienced council officers and their consultants

How to gain access to the CCC transport models?

Developers and developer agents interested in finding out more should contact the Transport Modelling team.

There is a range of one-off fees for accessing the models, depending on the model required and the size and type of development.

Use of CCC transport modelling for planning applications

All transport assessments of proposed developments will be judged on the impact, mitigation measures and validity of the results, irrespective of the forecasting models used. Use of the CCC models will not guarantee or imply a favourable planning decision.
