The first application of DELTA was for Edinburgh. This was developed by DSC as a prototype application, in collaboration with MVA and the University of Leeds Institute for Transport Studies (ITS). MVA provided the START model of Edinburgh to which DELTA was linked. ITS provided substantial assistance in model implementation and calibration, with financial support from the Engineering and Physical Sciences Research Council. The model was subsequently used by ITS for a major project in EPSRC's Sustainable Cities programme.
A second urban application, again in collaboration with MVA and again linked to a START application, was developed to form the Greater Manchester Strategy Planning Model (GMSPM). This was commissioned by the Greater Manchester Passenger Transport Executive (GMPTE) and the Highways Agency. This was used for a variety of project work by several different teams, with period updating, until recently replaced by the more extensive and more detailed GMSPM2 model.
The Edinburgh prototype and the GMSPM model were both designed as models of single cities. The integrated urban/regional form of DELTA to cover multiple, interacting city regions was developed in 1998 for Strategic Environmental Assessment of the Trans-Pennine corridor. The overall structure of DELTA has remained essentially the same since then, although the details have been extensively refined in successive projects, and not all applications have used the full structure.
Subsequent major applications which have used the complete urban/regional DELTA system for modelling full land-use/transport interaction include
The sub-regional models we have developed, with slightly less detail in the regional economic modelling (but other more sophisticated features), include
The DELTA urban models include
Several DELTA-based models with special characteristics have been developed in the course of specific projects - these include
These are (or will be) described on our research pages.
