Despite the high demand for MPT, it occupies a lot of space and contributes to conflicts and reduced livability. The more sustainable mobility solution of PT, however, is often considered slow, unreliable, and uncomfortable. To overcome these issues, the authors investigate the state-of-the-art research of connected PT mobility, including ways to quantify mobility behavior, micro- and macro-simulations of traffic flow, and the potential of not-yet-established modes of transport such as Mobility on Demand (MoD) for last-mile transportation. MoD could reduce the drawbacks of PT and provide sufficient and sustainable mobility to all citizens, including those in rural areas. To achieve this, precise information on individual traffic flows is needed, including origin–destination (OD) relations of all trips per day. The paper outlines a two-step approach involving the expansion of OD relations to include all modes of transport and diurnal variation, followed by microscopic traffic simulations and macroscopic optimization to determine potentials for on-demand offers within inner-city traffic. The paper concludes by calling for critical questioning of the approach to validate and verify its effectiveness. 4950 https://doi.org/10.3390/su15108171$xR$3Volltext$534 4950 https://nbn-resolving.org/urn:nbn:de:hbz:465-20230810-134856-2$xR$3Volltext$534 4961 https://duepublico2.uni-due.de/receive/duepublico_mods_00078535 5051 620 5550 mixed-integer programming 5550 mobility on demand 5550 modal-shift computation 5550 public transport 5550 time-dependent graphs 5550 travel resistance
