Samenvatting
The article deals with the subject of car ownership, car use and air pollution. A simulation model (FACTS) is presented by which forecasts can be made of car ownership and use, air pollution, fuel usage and government income from inter alia road taxes and excise duties. It is concluded that the model behaves reasonably well having been tested for the base year (1985) and "backcasting" the year 1981. A simulation run for the year 2010 predicts a growth of both car ownership and use of 70%.
