As part of the traffic impact study for the 2013 State Garden Exhibition in Sigmaringen, the requirements for managing and directing the expected visitor traffic as well as providing sufficient and attractive parking supply were determined. Furthermore, the effects of the closure of the Burgenstraße Bridge during the Exhibition on the transport system of the city were investigated and illustrated.
As part of the parking space concept, the available parking spaces were assessed and evaluated for two possible traffic generation and mode choice scenarios. For both scenarios, the necessary additional parking space for private transport and coach buses parking facilities were dimensioned and proposal for their location and layout illustrated. The effects of the closer of the Burgenstraße Bridge were investigated in terms of private transport, public transport and non-motorized traffic. Alternative bus routes were proposed and the required changes to stop sequences and timetables prepared. The effects of the detour on trip distance and time for private transport were quantified. Regarding pedestrian traffic, a survey of pedestrians on the bridge was conducted. The origin / destination as well as the trip purpose for a representative sample of pedestrians were surveyed and extrapolated for the entire pedestrian traffic.
