This paper presents a methodology for generating an origin-destination matrix (ODM) that integrates trip generation, attraction, and distribution—an approach rarely found in the literature. It leverages secondary data, such as population and housing censuses and databases on job, education, commercial, and recreational facilities (Points of Interest, POI). Trip generation is calculated based on the a-posteriori probability of an individual undertaking a trip to fulfill a specific need, considering the socio-demographic characteristics of each individual in a Traffic Analysis Zone (TAZ). The model determines trip attraction based on the Points of Interest (POIs) within each TAZ and models trip distribution using Gravity, Regression, and Logit Models, factoring in generalized cost between origin-destination pairs. This versatile methodology estimates ODMs for motorized and non-motorized transport, many trip purposes, and at different frame times. Its flexibility and applicability to diverse scenarios set it apart from existing studies, which typically only address some of these dimensions simultaneously. Moreover, the approach does not require an initial ODM, making it particularly useful in regions needing more detailed travel data, such as urban zones in developing countries. Only a few household surveys are needed for calibration and validation, underscoring the method’s cost- and time. The ODM reveals the spatial distribution of population groups and facilities, providing essential data for urban planning. It helps decision-makers balance service supply with mobility demand, reduce inter-TAZ travel, enhance zone autonomy, and promote sustainable urban environments.
