Popis: Autonomous vehicles (AVs), but in particular shared autonomous transit on demand (ATOD), promises many efficiencies in future transport provision, and may lead to concomitant changes in urban form. Considering the effects of car-oriented planning on the livability, efficiency and sustainability of 20th century cities, there is growing interest in how we may anticipate the changes that this disruption will bring about. Parking and pick-up drop-off infrastructures are some of the several aspects which may change travel behaviour in the upcoming era of AVs. In the paper, three different parking strategies as well as four types of pick-up drop-off infrastructures are simulated to assess their influence in users and operators. The studied parking strategies include demand-based roaming, parking on the street and parking in depots. The four types of pick-up drop-off interfaces are infinity bay, demand-based bay, curbside and single vehicle. The proposed fleet include 3 vehicle sizes: 4-, 10- and 20-seaters for sharing mobility, and 1-seaters for private mobility. Combinations of different parking strategies and different pick-up drop-off infrastructures were evaluated from the perspective of travel time, walk distance, vehicle occupancy, rejected requests and vehicle kilometers traveled. Results show that strategies produce radically different utilization of vehicles to provide the same minimum service level for a particular study area in Singapore. We conclude that urban designers and policy-makers need to consider these as important parameters when designing or retrofitting neighborhoods if they want to maximize potential benefits from this new transportation mode.
