Abstract

The extensive market introduction of autonomous vehicles will be revolutionary for traditional transportation systems. Especially today's clear boundaries between private and public transportation systems will blur. Due to the possibility of an autonomous relocation of cars, car-sharing will become more relevant and compete the protected taxicab market in Germany. Private car ownership might even become redundant. Having these possible future circumstances in mind, we use a microscopic travel demand model to simulate the mode choice behaviour in a case study for the Stuttgart region: we presume a world without private cars and the presence of a large autonomous mobility on demand (AMOD) service instead. Following, under the assumption that up to four persons share a ride, we calculated the number of cars needed to run the AMOD service smoothly. We show that not all trips, previously made by private car, are substituted by the AMOD service; the modal share of walking, public transportation and bicycling is increasing as well. Due to lower cost of the AMOD service compared with car trips, trip lengths increase as well. The results show that about 45% of all vehicle movements and 20% of all vehicle kilometres could be saved. Furthermore, the results show that about 85% of all vehicles in the Stuttgart region might be dispensable.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
