This paper proposes a model for parameterizing time dependent origin-destination (OD) matrices. This model builds the basis for the exploitation of high frequent count data for the estimation of OD-matrices. Such data sets become increasingly available due to recent advances in automatic pedestrian counting technology paired with a business interest to analyze the number as well as the fluctuation of the number of customers for shopping centres or passengers for junctions of mass transport. OD-matrices are needed for simulation, monitoring of the demand and (depending on the location of the counting sensors) for the evaluation of the attractivity of parts of the building. The model contains a full specification of the data set including a stochastic model for the measurement errors which directly suggests a method for the estimation of the parameters.
