Peter has been developing other people’s transport modelling software since 1976. In 1988 he started Peter Davidson Consultancy for transport planning, railways, research and software. In 1991 he started Visual-tm software development with ERICA followed by networks, mode choice, stated preference and tools, with the distribution model being added in 2000. During this period it was used for dozens of projects including major schemes, highway models, LTPs, toll roads, airport access, new air services, freight and transport strategies.
From 2001 to 2003 it was completely re-engineered, re-written and re-tested. In
2004, we re-branded it as Visual-tm (short for Peter Davidson’s Visual Transport Modeller) and
re-launched it (May 2004) with version 2 (May 2005) and version 3 (May 2006). It has continued to deliver successful projects ever since.
New features in version 3:
- Time of day assignment modelling
- Highway junction delay
- Public transport overcrowding and delay
In the past year, Visual-tm has been tried and tested on the following major projects: Ashford masterplan, Merseytram demand and revenue forecasting, Gloucestershire Regional Spatial Strategy, Gloucestershire major scheme bid and Truro major scheme bid. We are also calculating the National Core Accessibility Indicators for DfT.
