Urban trips have a wide variety of purposes. The above figure illustrates a typical set of daily trips associated with one employed individual with a child; an activity space (daily spatial behavior). Although the individual is directly involved in passenger movements (in this case as the driver), freight trips are

Variations in the urban transport demand by purpose are observed according to income levels. The higher the income, the more trip generated, but each type of trip has a different elasticity. Work-related trips tend to have little elasticity since they are the most fundamental forms of mobility, irrespective of income.

Source: adapted from American Public Transportation Association, Public Transportation Fact Book. The impacts of individual mobility and motorization on urban transportation have been significant. The outcome was a substantial decline in the share of public transit in urban mobility to less than 2% of the passenger miles in the early

Photo: Dr. Jean-Paul Rodrigue, 2007. The streetcar, although sometimes seen as an artifact of transit, is still a prominent form of public transportation in many cities around the world, such as in Lisbon, Portugal. This particular system began to be constructed in 1873 and has been operating with similar technology

The introduction of urban transit systems in the mid-19th century permitted the first forms of separation between the places of work and residence. By the middle of the nineteenth century, higher-income households relocated to relatively rural locations and commuted by rail into the city center. The “commutation” of fares to

Source: London Transport Museum. Although the first omnibus services appeared in Nantes in 1826 and Bordeaux in 1827, the first wide-scale commercial public transit ventures began in 1828 in Paris. Stanislas Baudry, a retired French general, had been experimenting with a scheme to draw new customers to his steam bath

Source: adapted from A. Bertaud (2001) Metropolis: A Measure of the Spatial Organization of 7 Large Cities. Cities can structurally be classified as polycentric (more common) or monocentric and major urban mobility flows as organized or disorganized (more common). Flows can be classified as primary, reflecting main road and transit

Urban areas, as economic units, are influenced by globalization in the scale and scope of their development. Since globalization was relying on different technological and economic drivers through time, this temporal
