In highly frequented tourist areas, tourist trips can occupy a major part of the traffic volume. This paper covers the integration of tourists in an already existing macroscopic transport model of the province of Salzburg.
The cross-border project "EuRegioBahnen Salzburg - Bayern - Oberösterreich" (ERB) is funded by the European Union with funds from the European Regional Development Fund ERDF (INTERREG). Within the ERB project, a traffic concept for public transport was developed and evaluated for the cross-border region of Salzburg city. The main objective of the project is to foster public transport and to create a relief effect of the city, the country and the traffic, while the mobility needs of citizens, commuters and tourists, should be met. This paper covers the integration of tourists in an already existing macroscopic transport model of Salzburg.
The province of Salzburg is a highly frequented touristic region with 26.2 million overnight stays per year. The tourism intensity is with 48 overnight stays per inhabitant higher than in Austria’s capital Vienna. Due to big ski resorts in in the south of the province there is a lot of touristic traffic especially in the winter season. At weekends traffic congestions produced by the overlap of arrivals and departures and day tourists occur. In the summer season a high traffic volume in the capital Salzburg and the closer region can be observed. So far, tourist traffic is barely recognized in transport modelling, because the available data in this field is sparse or even non-existing. There are only some statistics available about the behaviour of tourists concerning arrival and departure, but no statistics about traffic behaviour at the holiday resort. Touristic traffic is part of leisure traffic and can also be classified as very spontaneous and difficult to describe.
The current macroscopic transport model of Salzburg, called “VerMoSa” is based on an analysis of working day traffic. In the current model touristic traffic got no attention, there are no touristic OD-groups or structural data. This paper describes the development of two independent demand models for touristic traffic in the province of Salzburg for summer and winter season. VerMoSa is using VisEVA, an activity-based approach for calculating the traffic demand. This simultaneous working approach is advantageous for modelling traffic flows which are induced by touristic traffic. Relevant touristic demand objects and structural data must be created for developing the models. The number of tourists at the holiday resort is used for the structural data at the origin and a newly defined tourist attraction potential is used for the structural data at destinations. As data base for the touristic traffic behaviour acts a survey which was conducted in hotels in the relevant area. In this survey characteristic parameters of sociodemographic and traffic data of tourists (trips a day, number of passengers in a car, modal split and mobility rates) were collected.
The final paper will include the evaluation of the survey, which include an analysis of tourist mobility behaviour and the calculation of the traffic demand with the two touristic demand models. The assignment results from the demand models will also be compared with collected data and data form literature.
