Which methods are offered for matrix correction and for updating of existing demand matrices and which differences do they have?
Basically, the following methods are available: 1) TFlowFuzzy: - To adjust a given OD matrix in such a way that the result of the assignment closely matches the observed link volumes or origin/destination travel demand: - For PrT and PuT. - For Link volumes. - For OD travel demand by zone. - For Turn volumes at nodes. - For Any combination of these three. - Counts and tolerances. - Use of user defined attributes.
2) Matrix calibration: - Calibration procedure according to Lohse. - Only counts, no tolerances. - Only AddValues, no user defined attributes.
3) Projecting PrT Path Volumes: - Adjusts the OD-matrix of a certain PrT Demand segment to count data of certain manually choosen links. - Only counts, no tolerances. - Only AddValues, no user defined attributes.
