Aufteilung von erholungsaktivitaeten im raum und in der zeit

Abstract

The thesis contributes to the improvement of the methodical apparatus of recreation and transportation planning both in the field of long-distance and short-distance recreation. The author has developed models of the space-time allocation of extra-urban recreational activities. In the first part of the thesis the traits of the long-distance recreation are investigated focusing on the coastal-oriented domestic tourism in Greece at a spatially aggregate level. The dependent dimensions specified, structured in a recursive sense, concern: - the attracted site-specific tourist demand on a transregional level (attractiveness model) - the interaction-framework of generation and distribution of recreation demand (simultaneous model). The multidimensional character of the natural and cultural attractiveness of the holiday areas is considered through development of activity-specific composite indices. Based upon the models developed, an impact assessment and comparisonof policy alternatives is undertaken (e.g. introduction of anew tourist site in the recreation system with alternative scalesof development, respectively changes in the transport system).From the findings may be derived, that in the short-run: - the newly generated tourist demand that originate in any agglomeration is more affected by the level of the socioeconomic characteristics of the agglomeration than by the level of the supply of tourist opportunities. - the newly generated demand (production effect) compared to the diverted from all other opportunities (substitution effect) - like the effects of the e.g. introduction of a new or improved tourist site in the recreation system - does not represent the critical magnitude; the competition among the opportunities being for more decisive.

The second part treats the short-distance recreation on summer weekends at a disaggregate level, dealing with the recreationists emanating from Greater Athens Area with the trip purpose of swimming in the sea. Recognising the household as the decision-making unit for recreational travel choices, following choice situations, structurally related in a sequential-recursive manner, are modelled: - the (discrete) frequency choice - the (continuous) duration choice conditioned by the frequency choice - the (discrete) destination choice conditioned by the duration and frequency choice. Both former choices describe in particular how the households allocate time to swimming activities. Special attention is paid to the consideration of spatial, temporal, informational and/or role-related (i.e time geographical) constraints of the households, respectively to their subjective perceptions of environmental attributes. The short-distance recreation system considered, we may state that - relative to the destination choice, policies improving the relative location of recreational sites are more efficient concerning spatial demand dislocation than policies improving site attractiveness per se, very effective, concerning the same dislocation are zoning policies for second homes in the coastal areas - the destination choice is more sensitive to spatial policies affecting the overall accessibility of the households to swimming opportunities than frequency choice.
