The relationship between transit success and density is one that should be considered when planning transportation. Transit lines need to consider cost per passenger-mile in order to ensure financial feasibility. Some scholars suggest minimum density thresholds for successful transit of different types, but these rules do not always represent accurate ridership numbers. However, higher density in cities generally makes transit more feasible.

"Beyond Mobility is about prioritizing the needs and aspirations of people and the creation of great places. This is as important, if not more important, than expediting movement. A stronger focus on accessibility and place creates better communities, environments, and economies. Rethinking how projects are planned and designed in cities and suburbs needs to occur at multiple geographic scales, from micro-designs (such as parklets), corridors (such as road-diets), and city-regions (such as an urban growth boundary). It can involve both software (a shift in policy) and hardware (a physical transformation). Moving beyond mobility must also be socially inclusive, a significant challenge in light of the price increases that typically result from creating higher quality urban spaces."

Through a review of long-range transportation plans and interviews with planners, this article examines how large metropolitan planning organizations are preparing for autonomous vehicles. In just a few years, the prospect of commercially available self-driving cars and trucks has gone from a futurist fantasy to a likely near-term reality. However, uncertainties about the new technology and its relationship to daily investment decisions have kept mention of self-driving cars out of nearly all long-range transportation plans.
