The ‘Capacity Planning’ department of SBB‘s passenger transport division is responsible for planning and operating an attractive and dependable rail service that meets both current and future demand. To best meet these capacity requirements, since 2001 SBB has relied heavily on PTV Visum for strategic planning and analysis. PTV Visum is the leading software for traffic analysis, traffic forecasting and GIS data management, and was specially integrated into ‘SIMBA’, SBB‘s internal planning and modelling landscape. PTV Visum is used to visualise the network, calculate demand, identify and select optimal routes, map traffic flows, and manage timetables and services.
