Third Party Model Access Protocol
Gloucestershire County Council (GCC) in partnership with National Highways (formerly Highways England), as Highway Authorities within Gloucestershire, have developed a suite of highway assignment models. The choice of traffic models currently available comprise the following;
- Central Severn Vale SATURN highways Traffic Model (CSV Model)
- A46/Tewkesbury S-Paramics Model.
- The Gloucestershire Countywide SATURN Model (GCTM).
The suite of highways traffic models can be / have been used to;
- Assess the impacts of individual planning applications;
- Assist in the development of Local Plans and emerging land use allocations.
- Inform the development of GCC’s Local Transport Plan and Capital programme.
Details of how to access Gloucestershire’s suite of highways traffic models, as well as information on the associated Model Access charges, are provided in the Third Party Model Access Protocol.
Stroud District Council (SDC), working in partnership with Gloucestershire County Council and National Highways has developed a series of 2040 future year forecast traffic modelling scenarios using the initial version of GCC’s Gloucestershire Countywide Traffic Model (GCTM version 1.0), to help inform the assessment of proposed development site allocations as part of the emerging Stroud District Local Plan (2040). GCC has developed a Model Access Protocol to the GCTM and other GCC owned transport models, to enable external third parties to assess the impact of individual planning applications. Whilst the GCC Model Access Protocol deals with arrangements for third parties to access the GCTM models and to undertake specific model testing, the supporting data and traffic modelling inputs/outputs that form the Stroud Local Plan 2040 future year forecast scenarios are owned by SDC and access to this data is subject to the agreement of the District Council.
