Developing forecasting models and appraisal methods

Since the late 1990s, our modelling work has been concentrated on the development and use of the DELTA package.  Work on the design of DELTA started in early 1995; that original design has proved remarkably robust, but the detail of the package has been greatly refined and extended.  A description of the current DELTA package can be found via the "DELTA package" link at the top left of this page.  Below that, the "DELTA applications" link leads to a summary of the major models that have been built using the DELTA package - most, but not all, linked to strategic transport models so as to create land-use/transport interaction models.

The next three links relate to DSCMOD, an earlier and much more limited modelling approach which we developed in the early 1990s.  For most purposes, this has been replaced by the use of DELTA, but there are still some occasions when the use of the DSCMOD method may be appropriate.

The final link refers to our contributions to developing various other models.
