Peter Davidson - Managing Director
Peter is a Chartered Civil Engineer with 35 years experience in Transport Planning and is an international expert in transport modelling. His experience covers all forms of transport including rail, air, sea, road, high speed rail, new air services, quality bus, park and ride. Public Private Partnership toll roads and bridges. He has prepared transport plans, prepared business cases, undertaken scheme appraisals and provided transport planning advice for many cities and countries.
Peter is an international expert in transport modelling who has been instrumental in developing new transport modelling techniques. He 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.
He is an experienced transport planner who has been responsible for moving the profession towards more carbon-friendly modes of transport such as park and ride and cycling.
After extensive experience with consultancies and the public sector prior to 1988, Peter then formed his own consultancy Peter Davidson Consultancy Ltd to specialise in transport planning and modelling. As a specialist in modelling he has an especially keen eye for developing new transport plans and measures, which will actually work in practice. He tends to have a long-term relationship with his clients including nearly 20 years with DfT for example.
Peter has undertaken 200 transport planning studies while at PDC for which the consultancy gained a strong track record including the following example projects:
- Multi-modal transportation studies of the West Midlands, Taunton, Yeovil, Bridgwater, Woking, Epsom, Kendal, Kent Public Transport Strategy Study, Tajikistan for the UN
- Multi-mode transport models: Transport Model for Scotland, Cheshire Sub Regional Model, Gloucestershire County Model, Ashford Area Strategic Transport Model, Truro Transport model
- Traffic models: Eastern Region Traffic Model, South Eastern Regions Traffic Model, City of London traffic model
- Transport research several studies for: the UK Department for Transport (DfT), the European Commission, Transport Research Laboratory, the Scottish Office, Activity based parking model for Truro
- Toll road studies for National toll road strategy for Morocco, Transaction Advisor for PPP studies for Shagamu-Benin-Asaba-Onitsha-Enugu (1000 km), Niger, Ibi, Baruku, Digital toll Bridges, Lagos-Ibadan Expressway, Nigeria
- Stated and revealed preference studies for British Rail, Network SouthEast, Northern Spirit and other train operating companies
- Cycle studies: Leatherhead, The Eden Project
- Bus studies for Centro, the Eden Project, Truro
- Park and ride: Bedford, Kendal, Truro, Preston
- Light rail studies in Liverpool, Kingston, Bristol, Leeds, Portsmouth, Loyang China
- Heavy and high speed rail Middle East HSR, Great North Eastern Railway Co (GNER), Kings Lynn to King Cross, Rural rail in Essex, West Coast mainline, Gloucester Parkway, Eurotunnel.
He has recently undertaken a series of PPP studies for toll roads in Nigeria, is still undertaking more there and is helping the Tajik Government and the United Nations prepare a transport plan for Dushanbe which maximises air quality. He has recently been awarded responsibility for the development of the Transport Model for Scotland by the Scottish Government's Transport Scotland in consortium with SIAS, WSP and AMEY. He was responsible for helping Eurotunnel specify, evaluate and let a series of major market share studies to consultants so as to forecast the short-term build-up of traffic and revenue on Eurotunnel. He went to China for the World Bank to help negotiate a huge loan for the Chinese Government. He built a passenger and freight database and forecasting model of Eastern Europe from Ukraine/ Moldova, through Azerbaijan, Georgia, Armenia, through Kazakhstan, Uzbekistan, Tajikistan, Turkmenistan, Kyrgyzstan to Mongolia for the European Commission. He was part of the Dateline consortium, which did a household long-distance travel diary survey covering the whole of Europe for the European Commission. He led the 2 million euro MYSTIC project to prepare travel matrices for the whole of Europe. He has applied transport models for roads and LRT in China, a national toll road system in Morocco and airport access in Kuala Lumpur. He has also worked in Hong Kong, Malaysia, Dubai, Qatar, Bahrain, Jordan, Saudi Arabia, Algeria, Morocco, Nigeria, Romania, Bulgaria, Azerbaijan, Ukraine, Kazakhstan and China.
He has developed several transport modelling software products and directs PDC's transport planning and modelling software activities. He developed Peter Davidson's Visual Transport Modeller (Visual-tm) which covers all the tools needed to build transport models and use them to forecast patronage, traffic, revenue, undertake scheme appraisal, optimize the design of a transport system, devise public transport operations, provide environmental improvements and accessibility planning. The software has an innovatory highway assignment with junction delays which model the queue build-up using time dependent queuing and assignment.
Rob Culley - Principal Consultant
Rob Culley is a principal consultant and experienced project manager with 19 years' transport planning and modelling experience with PDC. Since joining PDC in 1997, he has been building and applying statistical transport models, developing modelling software tools, applying and undertaking fundamental research in transport planning. He has been responsible for developing the Consultancy's transport modelling software (Visual-tm) and is project director for the development of Visual Choice, the Consultancy's Choice Modelling software.
Rob has recently been developing and running a CUBE model of Scotland used by Transport Scotland for planning and development of major transport schemes. In particular, he has developed an innovative long distance module for this model which will be used to assess the impact of a major highway upgrade.
Rob has worked on projects for the UK Department for Transport, the Corporation of London, and Nigeria PPP schemes, as well as a range of other UK and international projects. Rob is a statistical modeller and physicist with a BSc (Hons) in physics (1988), an MPhil in physics (1991), two years research experience in laser physics with the University of Southampton and is a Member of the Institute of Physics.
Majid Adeeb - Principal Transport Planner
Majid is a Principal transport planner with over 26 years' experience in transport planning, design, research and congestion monitoring programmes. Has successfully managed over 157 national and international transport planning and research projects. Experienced at delivering high profile extensive data collection projects, to fulfil complex briefs within tight timescales and budgetary constraints. Diverse international experience, having managed various research projects in the Middle East Africa and Europe.
Principal areas of expertise include household travel diary surveys, stated preference (SP) surveys and Statistical Models and Analysis. Has conducted over 50 SP studies, testing mode switch propensity and value of time for business travel by rail and car.
