SWEDEN'S STATE OF THE ART REPORT TO THE INTERNATIONAL COLLABORATIVE STUDY ON FACTORS AFFECTING PUBLIC TRANSPORT PATRONAGE

The aim of this report is to collect and evaluate Swedish experiences from studies of factors affecting public transport patronage and to analyse factors affecting travel patterns and modal choice in urban areas. Development trends in urban areas and domestic travel are described together with a general framework of factors affecting travel consumption in a 40-year context. Four different methods of analysing travel behaviour are discussed and aggregated and disaggregated models are compared. Results from Swedish cross-sectional studies are presented. An analysis of different factors such as modal choice and demand elasticities is performed. This analysis comprises disaggregate studies using the logit model and studies based on aggregate data (a car ownership model and a transportation market - equilibrium mode - TRAMA). The interdependence between urban structure and travel pattern is analysed by means of three different sensitivity studies. The first of these studies uses the Ic-S-model, based on a combined cross-sectional and time-series data set. The two following sensitivity studies utilize the TRAMA-model as a tool for evaluating travel pattern in different urban structures. /TRRL/
