David Simmonds


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.

Emma Revill

Managing Consultant

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 the 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

Senior Consultant

Valentina is a consultant with expertise in land use 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 consists of a wide range of tasks including: model development; enhancement and calibration of DELTA land-use transport 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 with the help of GIS tools and SPSS.

In addition, Valentina has experience in liaising with other consultants and interacting with clients.

Mingfei Ma


Mingfei has degrees in Architecture and Environmental Design, and a PhD from the Department of Architecture, University of Cambridge. In her PhD project, she used urban land use and transport interaction (LUTI) models to assess the impacts of urban greenbelts on local businesses, residents and their travel behaviours. Her modelling skills lie in establishing, calibrating and validating LUTI models, and using them for policy tests. She also has experience in handling large amounts of data and establishing links among datasets. She has worked as a research associate in the Martin Centre for Architecture and Urban Studies in the University of Cambridge, where she used urban analytical models to assess policy appraisals for the Greater Cambridge and Greater Peterborough Enterprise Partnership.

He used a bespoke panel dataset including various economic, social and political data for around 40 different countries across the past five decades. Fixed effects and random effects regressions were used to quantify the main factors of growth across the 40 countries studied, before further analysis on Singapore in particular.
