Publication: Transport Mode Choice for Disaggregated Mobility Demand Generation

14.05.2025

Our new publication presents the integration of mode choice into our disaggregated mobility demand generator OMOD.

Abstract:
The OpenStreetMap Mobility Demand Generator (OMOD) is an open-source tool that creates realistic synthetic mobility demand for any region in Germany. The tool focuses on ease of use and fast prototyping, and requires only OpenStreetMap (OSM) data from the user. In this work, we introduce the aspect of traffic mode choice into OMOD. We utilize a two-stage multinomial logit model that works with precise origin-destination coordinates and exact departure times to determine each trip’s travel time and other level-of-service attributes based on network information acquired from OpenStreetMap and GTFS public transit schedules. We evaluate the performance of our model in two stages: first, directly on a separate test set of the household travel survey, and second, for a microsimulation of three different German cities. On the household travel survey, we reach accuracies between 64.3 % and 77.8 % with well-fitted calibration curves. Achieving high performance in the microsimulation is more difficult due to the existence of downstream errors. Nonetheless, we achieve close fits for all modes with the exception of the car passenger mode.
