With the emergence of several new providers of shared mobility services, such as Uber, Biketown and Car2go, there has been the promise of changes to the traditional way of owning and using a vehicle. One potential consequence of the new mobility services is the reduction in vehicle ownership. At the same time, cities are trying to anticipate these changes by reducing the amount of space dedicated to parking. This thesis aims to asses the extent to which new shared mobility and transportation policy strategies (especially parking requirements and transit pass availability) relate to vehicle ownership among residents of multifamily dwellings. To do this we use a web-based survey targeted to residents of multifamily apartments from Portland, Oregon.
