Oxfordshire Mobility Model: MIMAS project update - September 2020

Welcome to MIMAS and the OMM

MIMAS is the cloud-based transport modelling platform under development with Oxfordshire County Council which supports a move towards a self-service paradigm for modelling. MIMAS is being deployed in early 2021 for use in Oxfordshire as the Oxfordshire Mobility Model (OMM).

What can the OMM do?

Use-cases that can be modelled through the platform are the impact of new housing and employment sites, new roads, public transport improvements, reallocation of road space, parking availability, park-and-ride, impact of developments outside Oxfordshire. OMM is a strategic model and is not intended as a replacement for local models such as LinSig or TRANSYT. Some key features users will access though MIMAS are:
  • Interrogate the model results directly;
  • Visualise Key Performance Indicators (KPIs) to understand the impact of new infrastructure and development schemes;
  • Compare simulation outputs with observed data;
  • Track data and configurations back to source.
The KPIs available on the MIMAS platform include, but are not limited to, traffic flows, turning flows, average speeds, environmental metrics and congestion measures. The Oxfordshire Mobility Model (OMM) is being developed for a base year of 2019 and a do-min forecast year of 2035. Interim years can be developed as separate model runs, or results developed through interpolation, in line with standard approaches. The platform is being developed within existing guidelines, where the underlying model responds to interventions, such as increase in bus frequencies or road closures. However, innovative elements such as agent-based modelling and 24-hour simulations have been applied.   Transport modellers, consultants and developers can interrogate the model directly through MIMAS, and no particular knowledge of transport modelling principles is required.
