The origin destination matrix can be compiled using three sets of parameters: the mix of traffic (incoming traffic, outgoing traffic, inter-floor traffic and inter-entrance traffic) the floor populations and the entrance percentage bias (i.e., the relative strength of the arrivals at the entrance floors).
This chapter relaxes this restriction and shows a method for developing the origin-destination matrix that allows any floor to either be an entrance floor an occupant floor or both. However, that chapter placed the restriction that any floor must either be assigned as an entrance floor or an occupant floor, but not both.
A previous chapter described the methodology for constructing the origin-destination matrix (OD matrix) from the user requirements. The row index denotes the origin floor and the row index denotes the destination floor for the passenger journey. The origin-destination matrix is a two-dimensional matrix that describes the probability of a passenger travelling from one floor in the building to another.
