About the Project

Microscopic traffic simulations coupled with instantaneous emission models have the potential to provide improved assessments of the environmental impact of traffic networks, management strategies and technology implementations. Predictions of vehicle emissions (CO2, NOX, CO etc) using current ‘average-speed’ tools (e.g. www.NAEI.org.uk) do not adequately consider: local speed profiles/ driver behaviour or the benefits of smoothing traffic flow by environmental traffic management strategies e.g. green wave strategies and gating policies. Emerging instantaneous emission models are able to consider for any given speed profile, the influence of road gradient, vehicle loading, engine speed and gear selection on fuel consumption and emissions for Heavy- and Light-duty vehicles. Instantaneous emission models require speed trajectories (or profiles) as input, which can either be obtained from tracking systems (measured) or are an output from traffic micro-simulation models.

The Institute for Transport Studies (ITS) is collaborating with the Institute for internal combustion engines and thermodynamics, Technical University of Graz (TUG, Austria) and has developed, evaluated and applied a coupled traffic micro-simulator and instantaneous emission model (Zallinger, Tate et al, 2008 and 2009). Supported by detailed observations, there is now an opportunity to use these tools to provide improved environmental assessments of traffic networks and environmental management strategies using the best available/ internationally leading Scientific software tools. It is suggested the Headingley district in Leeds is used as demonstration site as a wealth of traffic flow, congestion, driver behaviour and environmental data is available for this area, to support the rigorous calibration and validation of the traffic micro-scopic simulations. There would be an opportunity to under-take a 3-month research placement at the TUG, Austria as part of this PhD project.

Career overview

Dr. James Tate is an Associate Professor at the Institute for Transport Studies, University of Leeds. He holds a BEng (Hons) and an MRes in Civil Engineering from the University of Nottingham, as well as a PhD from the University of Leeds. Dr. Tate''s research focuses on the impact of road transport on the environment, where he develops and applies innovative approaches to survey and model the emission performance of the UK and EU road transport fleet. He is recognised as a UK pioneer in vehicle emission remote sensing and serves as co-chair of the European Research on Mobile Emission Sources remote sensing working group. His work includes advancing detailed emission models linked to traffic microsimulation models and high-resolution telematics data. Dr. Tate utilises his research to design, assess, and forecast the effects of policy interventions such as Low Emission and Clean Air Zones, and to promote and incentivise Low Emission Vehicles. He has contributed to shaping the UK Air Quality strategy through various projects and roles for the European Commission, DEFRA, DfT, Local Authorities, and TfL. Notably, he provided oral evidence to the Commons Select Committee on Vehicle Type Approval in December 2015.
