Peter Davidson Consultancy
undertakes specialist transportation modelling projects for clients especially
where this involves difficult modelling problems. We are at the forefront in
transport modelling including the development of innovative techniques. Peter
Davidson has developed his leading-edge Visual Transport Modeller (Visual-tm)
software for transport modelling which we use on projects and market internationally.
Peter is a leading international authority on transport modelling and has been
responsible for major innovations in modelling techniques including park and
ride assignment, matrix building, matrix estimation, stated preference and
disaggregate modelling. The consultancy has undertaken over 100 modelling projects
so far and is well known in the field as a consultancy to be watched!
We are specialist at building very large models for clients, including regional
highway models. We have developed the techniques into those recommended by the
Department for Transport (DfT) today - especially for building complex origin-destination
matrices, where we developed DfT’s ERICA software which is the industry-standard
for matrix building. We have built two very large regional traffic models for the
Highways Agency covering the east (ERTM) and southeast regions (SERTM), linked
together to produce an inter-regional traffic model for the whole of the southeast
and after being updated to 2001 it is still being used for scheme identification
We develop public transportation models for clients to forecast the ridership and
revenue of a transportation system, undertake economic appraisal (eg TUBA, COBA),
prepare business cases so as to support bids for franchise or funding. Our models
can also be used to refine a system's design, optimise its operation, investigate
it's future target markets and assess it's popularity. They support revenue and
funding decisions for private clients such as Merseytram, GNER, Eurotunnel, and
for Major Scheme Bid submissions such as Gloucester and Ashford.
We build multi-modal models for clients which include the complex interactions
between modes, individuals' travel choice making behaviour and the supply/demand
equilibrium. Our models are capable of addressing such difficult problems as traffic
restraint, decongestion, park and ride, corridor switching, parking supply, tariff
structures and pricing regimes, new transport modes, significantly enhanced transport
systems, policy issues, ticketing, sustainability, pedestrianisation and travel
reduction targets and are capable of tackling very large and complex transport problems.
Examples of other modelling projects include PRISM, Eurotunnel, a Regional Spatial
Strategy model for Gloucestershire, A stated preference disaggregate model for Scottish
Air Travel, Rail/LRT models for LB Newham, South Hampshire LRT, Kingston and Kings Lynn,
LTP models for Epsom, Woking, Taunton and Kendal.
