Abstract
The regional model system presented here has the following characteristics: applicability to work days for the period 0- 24 hour, three trip purposes and three modes. Furthermore, it is possible to apply it to particular periods of the day, e.g. the peak hour, and to make calculations for selected areas at a much higher level of detail. The following five submodels are dealt with: 1) trip production and attraction, and intrazonal trips; 2) trip distribution; 3) modal split; 4) time split; 5) road and public transport network assignment. Apart from the usual explanatory variables use is made of two zone typologies: a classification of zones according to service level and employment, and one with respect to urban and non-urban areas.
