Professor John Polak is Professor of Transport Demand and Head of the Centre for Transport Studies at Imperial College London.

He is Director of the Intercollegiate MSc courses in Transport and coordinates the Universities' Transport Partnership. He is a mathematician by background specialising in the areas of travel behaviour and transport demand modelling.

He is a past President of the International Association for Travel Behaviour Research and a past Council Member of the Association for European Transport and past chair of the AET Applied Transport Modelling programme committee.

He is a member of the EPSRC Peer Review College and serves on the US Transportation Research Board's Committee on Traveller Behaviour and Values. He has served as an advisor to Transport for London on the design of LATS 2001 and the London Congestion Charging monitoring programme and to the Department on the quality assurance reviews of the NTS and of Road Freight Statistics as well as to the Singaporean and Norwegian governments on the modelling road pricing measures.

He has extensive experience of working with ITEA and its predecessors on a wide range of topics. Polak has been in the forefront of innovative transport model development in the UK for a number of years, contributing to the development of techniques for stated preference data collection, activity based modelling, econometric aspects of discrete choice modelling, the assessment of the welfare impacts of transport policy measures, the treatment of errors in revealed preference data. He has published extensively on a number of aspects of travel behaviour and demand including the effects of experience and information on trip planning and spatial choice, the modelling of journey scheduling and peak spreading, household activity scheduling, the influence of network unreliability on travel behaviour and the dynamics of day-to-day adaptation.
