Transportation policy is the public policy that regulates or affects transportation.

It's topics include:

Urban planning

Reducing externalities associated with the automobile depends in large part on urban planning moving cities and regions from car-oriented to transit-oriented patterns of urban development.[1] In the U.S. for instance, land-use and tax policies have supported suburbanization and auto dependence. Private vehicles remaining underpriced when their externalities are taken into account but imposing additional fees or taxes on auto users is politically unpopular while transit investment is often considered the second-best option.[1] The modal share and associated infrastructure qualities vary per city.

In climate change mitigation

When not including emissions from the manufacturing of motor vehicles or other transport equipment, transport emissions make up ~16.2% of greenhouse gas emissions, one of the largest sources.[3]

The Working Group III for the IPCC Sixth Assessment Report assessed "progress in limiting emissions, and the range of available mitigation options in energy and urban systems, and in sectors such as agriculture, forestry and land use, buildings, transport and industry".[4] The 2023 synthesis of the report concluded "Transport-related GHG emissions can be reduced by demand-side options and low-GHG emissions technologies. Changes in urban form, reallocation of street space for cycling and walking, digitalisation (e.g., teleworking) and programs that encourage changes in consumer behaviour (e.g. transport, pricing) can reduce demand for transport services and support the shift to more energy efficient transport modes (high confidence)" and that "Technology development, transfer, capacity building and financing can support developing countries/regions leapfrogging or transitioning to low-emissions transport systems thereby providing multiple co-benefits".[5]
