David Simmonds


David Simmonds studied Town and Country Planning at the University of Newcastle upon Tyne, and the use of mathematical models in urban planning for his PhD at Cambridge. During the 1980s he worked for the London Transport Executive as an Economic Analyst, and for Marcial Echenique & Partners as a consultant and subsequently as Technical Director. In 1990 David left ME&P to set up David Simmonds Consultancy, particularly to develop and apply improved methods of forecasting the interactions between land-use, transport and the economy. This led to the development first of the DSCMOD approach and, in 1995, to the first version of the DELTA package. David has since directed a wide range of DELTA-based projects including forecasts used in public inquiries for Edinburgh Congestion Charging and the M74 completion, and work for the Eddington Study. He has also been responsible for a numerous other studies including contributions to the SACTRA report on Transport and the Economy.

Alistair Halls

Senior Analyst

Alistair joined DSC soon after completing a degree in Geography at King’s College London. During his time at university, Alistair studied a vast array of different subject matters. This included urban (economic) geography, for which he penned an incisive piece examining firm location and spillover effects through a reading of Jane Jacobs’ Cities and the Wealth of Nations; and discussed how ‘smart cities’ policy has shaped Manchester. Alistair’s interests lie in modelling and GIS, and through his degree he pursued both of these, both within seminars and modules and in his dissertation. His dissertation looked at the need for incorporating time-dependent travel times into the optimisation of ambulance station locations, with a focus specifically on genetic algorithm-based modelling. To determine this, travel data from ambulances over a 12-month period was analysed and incorporated into bespoke inputs for a genetic algorithm/optimisation model. Prior to and during his degree, Alistair worked for a management consultancy firm specialising in health, the emergency services and facilities access. It was here that he developed an interest in GIS and modelling, operating the company’s many different models and utilising advanced GIS techniques. A key achievement at the company involved developing a method of analysing travel data and incorporating it into time-dependent travel time inputs for models – something studied further in his dissertation.

Elaine M Maclean


Elaine is a Mathematician with a background in combinatorics and applied mathematics. She joined David Simmonds Consultancy in June 2017 having worked as a Data Analyst in the technology expense management sector. She obtained a BSc(Hons) in Mathematics from Heriot-Watt University and a BA in Scottish Gàidhlig from Sabhal Mòr Ostaig (UHI). Within the field of combinatorics and statistical mechanics, Elaine’s dissertation focused on tilings of finite discrete structures in planar regions. Within the project, an algorithm for generating random domino tilings of discrete structures was scrutinised and subsequently optimised in order to efficiently encode the algorithm in the mathematical software package MATLAB. The project also explored the connection between the domino tilings and alternating sign matrices with relations to the six vertex model of statistical mechanics. Gaining proficiency in numerical analysis granted her the ability to analyse complex data sets, scrutinise and examine various approximation methods for systems of differential equations with applications in thermal imaging and planetary motion. Furthermore, mathematical biology modules provided her with thorough understanding of mathematical modelling. Such models were used to describe population dynamics, epidemiological and evolutionary processes in ecological systems.
