DIADEM (Dynamic Integrated Assignment and
Demand Modelling) software package has been
recently introduced to complement the variable
demand modeling process. The fundamental
impetus of DIADEM is to test the robustness of
highway scheme benefits and this software
package is intended to be complementary to
conventional demand modeling software. This
paper tests a small hypothetical network of a
town in the UK to compare the benefits under
the current conventional methodology and under
the DIADEM methodology
