Peter Davidson Consultancy build and use transport models for clients and have a 21-year sound track record for delivering all types of transport models ranging from the very simple single-mode corridor models, through the hierarchical choice models needed for DfT WebTAG multi-mode appraisal, to the innovative activity based transport models emerging as the new paradigm. PDC are at the forefront in transport modelling encompassing the development of innovative techniques such as activity based models, discrete choice models, stated/ revealed
preference models and incorporating travel behaviour. Peter Davidson is a leading international authority on transport modelling and has been responsible for major innovation in modelling techniques including park and ride assignment, matrix building, matrix estimation, stated preference and disaggregate modelling. Peter Davidson has developed his leading-edge Visual-tm (Visual Transport Modeller) software for transport modelling which PDC use on projects and market internationally.

Role in the project

PDC will lead and coordinate the modelling work in ESPRIT, work package 7 “Business model estimation tool developments”. Modelling at strategic, tactical and operational levels is all part of the work package, and the inputs and outputs at each level will depend on different models.
PDC will be responsible for delivering the business model for ESPRIT. This is an innovative approach to transport modelling, which will build upon its experience and skill in all aspects of transport planning. PDC has designed its own bespoke software package for advanced choice modelling which is marketed internationally, and that can be used as a development platform to research and develop the final methodology for LiTSyM.

Personnel involved

DAVIDSON Peter, male, is an international expert in transport modelling who has been instrumental in developing new transport modelling techniques. Peter is a computing expert, especially in developing new transport modelling software. He is expert at measuring the behavioural responses required for developing complex models of people’s travel choice making behaviour. He has been instrumental in developing new demand and revenue forecasting techniques. He has recently developed new discrete choice techniques for estimating latent class mixed logit, latent class nested logit and prepare efficient stated preference designs.
Peter will act as a technical expert to work package 7. His skill and experience in innovative transport modelling techniques will ensure that the objectives are reached within time and budget constraints, but that the skills of the participants are used to achieve the maximum possible.
PORTER Helen, female, is an experienced transport modeller with a good understanding of both traditional transport modelling methodology, as well as agent and activity based modelling.
Helen Porter will be leading ESPRIT work package 7 “Business model, Market, Traffic and modal share modelling”.
