David Simmonds is an internationally recognized specialist in analysis and modelling of the interactions between land-use transport and the economy, with over 30 years’ experience in this field. He established David Simmonds Consultancy (DSC) in 1990, and has led its growth to the present position where it is the leading practice in its particular field. He has also served as a Director of Marcial Echenique & Partners Ltd (ME&P) and of Hague Consulting Group UK (now part of Rand Europe).
At ME&P in the 1980s he was responsible for a wide range of studies using the MEPLAN package. He initiated the development of the DELTA package in 1995, and has been responsible for many enhancements and much of its application since then, in the UK and abroad, with a particular focus on the convergence of land-use/transport and economic modelling and the development of associated appraisal methods. His major projects in the last few years having included the development of land-use/economic models of France for the Société du Grand Paris and of Great Britain for Highways England, and the development of a new approach to combined land-use/transport appraisal for Transport for London, first applied to the Crossrail2 proposals. He is a regular contributor to professional conferences and to professional/academic journals, and an Honorary Professor at Heriot-Watt University, Edinburgh.
Richard Potter has been an Associate with DSC since 2012. He studied Geography at the University of Southampton and Town and Country Planning at the University of Newcastle upon Tyne.

Mélanie joined David Simmonds Consultancy in October 2005 after completing her Master’s studies in GIS and Remote Sensing at the University of Cambridge. She focused her M.Phil research on Transportation issues and undertook her final dissertation on Accessibility Modelling. Prior to joining DSC, Mélanie worked on various GIS-based projects related to diverse domains, including industrial risk assessment and agricultural management. At DSC she was initially involved in the programming of the DELTA package; she has since worked on a wide range of DELTA-based projects, as well as providing specialist GIS contributions across the firm’s work. She was responsible for the coordination of the TELMoS project in Scotland from 2008 to 2010, and is currently managing the development of a national land-use/transport interaction model of France for the Société du Grand Paris. In parallel, she is completing her PhD dissertation at the Centre for Advanced Spatial Analysis, University College London.
Emma is an economist specialising in land-use/tranport planning, modelling and economic appraisal. She has substantial experience in developing new applications of DELTA and in running DELTA models to appraise land use and transport schemes. For Leicestershire County Council, Emma undertook original research using the LLITM Household Survey to inform the calibration of the land-use model. This involved estimating binary logit models for the probability of a household intending to move and multinomial logit models for a moving household’s choice of location. More recently she has taken a leading role in the application of the FLUTE model for the Sheffield City Region. She has also worked on the Auckland model of DELTA since she rejoined the firm in 2006, and is currently managing the development of a new component to model land development taking account of competition from different types of floorspace.
Valentina Nacar is a Principal Consultant with expertise in land-use/transport planning, modelling and economic appraisal. She has been developing her technical skills in the field since she first joined DSC in 2010. Her role at DSC has included a wide range of tasks spanning development, enhancement and calibration of DELTA land-use\transport interaction (LUTI) models; collection, manipulation and processing of data for the database creation; setting up and running tests for the appraisal of transport and land-use schemes and analysis and interpretation of the results including the use of GIS tools and SPSS. She is also contributing to the maintenance and enhancement of DSC’s DELTA software package. She was team coordinator in the development of a national LUTI model for HS2 Ltd, and has since taken the same role in the development of a French national LUTI model for the Société du Grand Paris. Since October 2020 she has been Framework Manager for DSC’s work with Transport Scotland, with responsibility for the development and application of the national land-use/economic model, TELMoS, and for its interfacing with the national transport model (TMfS) and regional models. She has extensive experience in liaising with other consultants, interacting with clients and coordinating junior staff.
Alistair joined DSC as an Analyst in 2016, after completing a degree in Geography at King’s College London. He was promoted to Senior Consultant in 2020. In his time at DSC, Alistair has acquired extensive knowledge of the processes driving land-use and transport planning. He is an expert in the application of the DELTA package, and has provided training in its use to multiple clients. On top of this, he is skilled in the use of VBA and Python, which he has utilised to build tools and programs for DSC and client use.
