This paper describes refinements and extensions incorporated into the development of a LUTI model for the Sheffield City Region, and the design and use of a method to assess the economic and accessibility impacts of a range of different investments
This paper describes the development and application of a land-use and transport model for the Sheffield City Region. The model is known as FLUTE (Forecasting Land Use, Transport and Economy). It was developed in 2012/13 and is based upon the existing EMME-based transport model for the City Region and a DELTA land use model. It forecasts changes in population, households, employment, along with the land use they occupy and the trip patterns and flows that they generate. It has added functionality to model the viability of site development and remediation, to calculate the impact on GVA of different policy interventions. The former provides a more realistic pattern of spatial development (and associated trip generation) whilst the latter was a key requirement for prioritising a range of infrastructure schemes.
The model was used to support preparatory work on Sheffield City Region’s City Deal Bid. Specifically it was seen as a tool that would appraise the GVA impacts of schemes in a consistent way. The modelled schemes included enhanced public transport, highways and accessibility improvements, pedestrianisation and cycle ways initiatives, site remediation, public realm investment were tested using FLUTE.
In all, twenty-six different schemes were tested. For each a calculation was made of the impact on employment and GVA at City Region level, the impact upon each District authority area and the impact upon the most deprived areas of the City Region.
The final stage involved the testing of packages of two or more schemes. This was to identify where the impact of a combination of schemes was greater than the sum of the parts or conversely where schemes were part-substitutions for one another.
The FLUTE model and the use made of it for the Sheffield City Region represents a significant advance in the use of modelling methods to test a wide variety of proposed interventions taking account of a full range of land-use, economic, transport and social effects.
