Method for estimating intra-building traffic, and system for estimating intra-building traffic

An OD matrix estimation device comprising:

• an extraction unit that, on a basis of intra-bank OD matrixes that show traffic flow information in respective elevator banks in a plurality of elevator banks and transfer floor information about a transfer floor where transfers among the elevator banks are possible, extracts transfer-related intra-bank OD matrixes having a common transfer floor from among the intra-bank OD matrixes;
• a matching unit that, from among the transfer-related intra-bank OD matrixes extracted by the extraction unit, combines first transfer intra-bank OD matrixes each including OD data in which the transfer floor is defined as an arrival floor with second transfer intra-bank OD matrixes each including OD data in which the transfer floor is defined as a departure floor to create transfer-related OD data;
• and
• an estimation unit that, from the transfer-related OD data obtained through combination processing by the matching unit, estimates OD data for users who transfer and move among the banks to create a plural-bank OD matrix that is an OD matrix of the entirety of the plurality of banks.
