In principle, the calculation of skims between stop areas is analogous to the calculation of skims between zones. The calculation is performed via the procedure Calculate stop area skim matrix, either headway-based or timetable-based (Using Visum: Calculating stop area skim matrices). The results are output in matrices with the number of stop areas. The calculation is a mere skim matrix calculation. It is not based on the assignment results of demand. This means capacity restriction cannot be taken into account. The skim discomfort is not available.
Information on the temporal distribution, however, is still required. It is derived from the time series of demand segments, for which the skim calculation is performed. The time series used must be in per cent, as only then is there no reference to zones. You may also output skims between stop areas for analysis time intervals. In this case, the restrictions listed in the respective section apply (Skims of time intervals).
