In this paper, we simulate the impacts of Automated Mobility-on-Demand (AMoD) using SimMobility, an integrated land-use transport micro-simulation platform. Using data for Singapore, we examined the future scenarios in which AMoD is added as an additional mode on top of existing modes, or as an exclusive one. We found that AMoD may lead to changes in accessibility, which will consequently affect people’s behaviours. Our results show that a scenario in which AMoD is an additional mode is a preferred option, whereas the exclusion of AMoD will lead to lower accessibility for people in the study area.
