- A pervasive transportation network has helped transform the vast geographic expanse into a surprisingly homogeneous and close-knit social and economic environment. Another aspect of mobility is flexibility, and this freedom to move is often seen as a major factor in the dynamism of the U.S. economy.

To overcome geography, transportation requires a footprint. Transportation infrastructures are important consumers of space, which includes the right of way (e.g. roads and rail lines) as well as the terminals. Jointly they form transportation networks.

Cities are locations having a high level of accumulation and concentration of economic activities. They are complex spatial structures supported by infrastructures, including transport systems. The larger a city, the greater its complexity and the potential for disruptions, particularly when this complexity is not effectively managed. Urban product...
Automobile use is related to a variety of advantages, such as on-demand mobility, comfort, status, speed, and convenience. These advantages jointly illustrate why automobile ownership continues to grow worldwide, especially in urban areas and developing economies. When given a choice and the opportunity, most individuals will prefer using an automo...
Congestion can be perceived as an unavoidable consequence of the usage of scarce transport resources, particularly if they are not priced. The last decades have seen the extension of roads in urban areas, most of them free of access. Those infrastructures were designed for speed and high capacity, but the growth of urban circulation occurred at a r...
In some areas, the automobile is the only mode for which adequate transportation infrastructures are provided. This implies less capacity for using alternative modes such as transit, walking, and cycling. At some levels of density, no public infrastructure investment can be justified in terms of economic returns. Longer commuting tripsin terms of a...
As cities continue to become more dispersed, the cost of building and operating public transportation systems increases. For instance, as of 2021, about 205 urban agglomerations had a subway system, the vast majority of them being in developed economies. Furthermore, dispersed residential patterns characteristic of automobile-dependent cities make ...
One of the most fundamental relationships supported by transportation involves how much space can be overcome within a given amount of time. The faster the mode, the more significant the distance that can be overcome within the same amount of time.
Sep 1, 1994 · First, the paper considers the development of transport geography up to the 1970s, and the establishment of a strong linkage between transport study and the spatial-organization view as model building and spatial analysis were added to a long- standing concern with cartographic analysis.

Public transit policy is based on two objectives: to provide basic mobility for the transportation of disadvantaged, and to serve broader social and environmental goals by reducing car use in metropolitan areas of the United States.
Geographic changes can shift transportation demand or change transportation needs. Social changes influence preferences and expectations, while technological innovations change what is possible, including how activities are completed, the transportation services available, and the way goods and services are provided.
