Planning for Shared Mobility

Shared mobility refers to the shared use of a vehicle, bicycle, or other low-speed travel mode. In North America, shared mobility encompasses the submarkets of carsharing, bikesharing, ridesharing, on-demand ride services, scooter sharing, and alternative transit services. Shared mobility directly influences and is influenced by most facets of urban planning, including transportation, land use, urban design, economic development, conservation, and climate action. The latest PAS Report explores the impacts commonly associated with shared mobility modes and provides recommendations to planners and policy makers about incorporating shared mobility into plans and local policies.

PAS subscribers will receive the report in late July or early August and can download it here.

Others may order it from APA.

Historic Reports

PAS published its first Information Report in 1949. To celebrate this history, each month we'll present a new report from the archives. We hope you enjoy these fascinating snapshots of planning issues of yesteryear.

Information Report No. 126, September 1959

In the late 1950s, the subdivision of hilly areas was a new and growing problem as developers began turning to these once-bypassed areas after running low on more easily developed vacant flat land. This historic PAS Report draws on the few reports available on this topic at the time to introduce planners to the special zoning and grading challenges inherent in hillside development.
