| Abstract: | In microscopic travel demand models, all residents are modelled as individuals that each make their own choices based on their characteristics and circumstances. Modelling individual behaviour offers detailed insights into mobility patterns and the effects of policies on specific target groups. The travel demand modelling begins with the generation of a synthetic population, representing either a reference population or a future scenario. The current population synthesizer used by Dat.mobility and Goudappel has its limitations. During the last step, household compositions are not preserved, leading to inconsistencies, where characteristics of individuals do not reliably represent complete households. To ensure the new population synthesizer addresses these limitations, and generates consistent households, the population synthesis problem is formulated as a mixed-integer linear program that enforces both household consistency and compliance with marginal totals. Additional requirements are incorporated in extensions of the mixed-integer linear program. The proposed formulations are evaluated on a full-scale travel demand model using the open source solver HiGHS. |
