THE CHOICE OF MODE OF TRAVEL ACCORDING TO SPATIAL STRUCTURES AND PERSONAL PREFERENCES - A BASIS FOR THE EVALUATION OF PLANNING MEASURES IN SALZBURGS CENTRAL REGION

Measures in transportation planning aim at slowing-down the increase o f traffic and at a reduction of private cars in a modal split. There o bviously is considerable spatial influence as to modal split, but chan ges in modal split (1982-1994) are much more marked than changes in sp atial structure. These changes are mainly caused by behavioural change (to be interpreted as the spreading of ''urban lifestyles'') and an i ncreasing flexibility in activity timing, with an increase in the dist ances travelled, thus reducing the competitiveness of public transport . In order to achieve the planning objectives a bundle of measures hav e to be introduced simultanously. A decentral concentration of populat ion in specified centres in the surroundings of the city of Salzburg i s of paramount importance and has to be accomplished by improving publ ic transport in these centres and by measures for multimodal travel (B ike&Ride, Park&Ride).
