THE "SIGMO" STUDY. PART II METHODOLOGY. SPECIFICATION AND ESTIMATION OF DISAGGREGATE BEHAVIOURAL MODELS USED IN AGGREGATE FORECAST SYSTEMS

Part II of the "sigmo" study (stadsgewestelijk individueel geschat model, or individually estimated conurbation model) presents a discussion of the major theoretical and methodological issues that face transportation analysts who seek to apply disaggregate models to practical problems in transportation planning and policy analysis. Basic issues in the application of probabilistic disaggregate models to the problem of long range travel demand forecasting are discussed and the structure of the sigmo forecast system is presented. The problems of specifying and estimating the disaggregated models used in the sigmo system are also given. (TRRL)
