This is true not only in large cities, but also in many smaller communities and throughout entire metropolitan areas. Transit is used for about 10 percent of urban trips in Western Europe, compared with about 2 percent in the United States.

Canadians use public transit about twice as much as Americans, although there is considerable variation across Canada, just as there is in Western Europe and the United States. A number of factors have contributed to this differential, from higher taxes on motor vehicles and fuel to concerted efforts to control urban development and preserve the form and function of historic cities.
Western Europeans and Canadians have devoted considerable attention and resources to ensuring that transit service is convenient, comfortable, and reliable.
This report reviews these policies and practices and the historical, political, and economic circumstances that have influenced them. The focus is on comparing the largest industrialized countries of Northern and Western Europe, 1 as well as Canada, because their economic, social, and political conditions are most like those of the United States.
The comparisons provide insight into why public transit is used more in Western Europe and Canada, as well as ideas on how to increase ridership in the United States.

Grid-style street systems, ample land for expansion, thriving economies, mass immigration, and a general willingness by the public to try new transportation technologies fostered a streetcar revolution that swept across the country.
Hundreds of American cities were served by privately operated streetcar lines. In many respects, however, the same characteristics that gave rise to electric traction hastened its decline during the middle of the century.
Increasingly affluent and able to afford automobiles, Americans began buying them in droves after World War I. Byone of every four households owned a car, and by there was one car registered for every two Americans. The faster and more flexible automobile vastly increased the amount of land available for residential and commercial development.
Urban development could, and did, take place increasingly farther from the traditional central cities and early suburbs formed along transit lines. Large urban areas—many shaped almost entirely by the automobile—emerged after the streetcar era had passed.
Even as these trends were becoming manifest between the two world wars, little attention was being given to the lasting changes that were taking place in American cities, much less to the profound effects these changes would have on urban transit systems. Indeed, the migration of households to the suburbs—seeking better schools, more land, and larger homes—was generally viewed as a positive trend that would strengthen cities by relieving crowding and alleviating traffic congestion.
A host of government policies, from tax incentives that fostered home ownership to the construction of freeways radiating out from city centers, would come to reinforce and accelerate this outward migration.
Businesses soon joined the flow of people to the suburbs. As central cities lost households, jobs, and shopping places, transit use fell sharply. Not until the mids, however, did the diminishing fortunes of American cities and the intertwined fate of transit attract national attention, precipitating large-scale federal and state investments in public transportation.
By this time, the Page 3 Share Suggested Citation: Having limited political influence and contributing a dwindling share of operating revenues, these remaining riders endured declining levels of service.
Among more affluent travelers with other transportation options, transit usage fell still further. Today transit operators in the United States continue to face significant challenges in attracting and retaining riders. However, transit still plays an important role in the transportation systems of many large American cities, serving suburban commuters and city residents alike.
Renewed interest in its role as a complement to the automobile has arisen with recent increases in bus and rail ridership in several large urban areas; signs of central city rejuvenation; and a widening recognition of the importance of transit to the urban poor, disabled, and elderly.
Retaining and Rebuilding Transit in Western Europe By the time electric railways had been widely introduced early in the 20th century, most Western European cities were already quite mature, shaped by centuries of carriage by foot, water, and animal. Seeking to preserve their historic centers, many Western European cities were cautious in adopting new transit technologies—especially private streetcars.
Rather than entrust the private sector with supplying this service, many opted to build and operate their own electric streetcar systems. Thus almost from the beginning of the century, transit was treated as a public rather than private enterprise in Western Europe—in sharp contrast with circumstances in the United States.
Western European transit systems, both public and private, drew little competition from the automobile until late in the 20th century. Recovering from two devastating world wars, few Western Europeans could afford automobiles before the s, and fewer still could afford new homes farther outside the city.Same-sex An introduction to the reasons why germany was defeated in world war one marriage, the an introduction to the comparison of free trade and protectionism practice of marriage between two men or between two women.
- Traffic and Urban Congestion: In , Great Britain still had no urban freeways. But with the ownership of private cars becoming ever more common, the problem of congestion in British cities was unavoidable. This resurgence arose from many factors: growing ecological consciousness from the environmental movement of the late s and s, revolts by citizens against the negative consequences of urban freeways, energy crises, and general disillusionment with .
