Prior to the popularity of car use which dominated motorised transport from around the 1950s onwards, several transportation modes were used. Pedestrianism for both short and long distances was used, but also travel by horse especially for long distances. Trams, especially powered trams, achieved widespread popularity in the 19th century. Carriages, used for centuries, are still used but mainly for tourism.
The public transport with the highest modal share worldwide is travelling by bus followed by travelling by rail due to infrastructure cost. A pedestrian form of public transport is a walking bus predominantly used by schools. An attempt to transform private transport by bicycle into public transport has been bicycle sharing schemes. Bicycle-sharing systems have been implemented in over 1000 cities worldwide, and are especially common in many European and Chinese cities of all sizes. Similar programs have been implemented across the United States as well, including large cities like Washington, D.C., and New York City, as well as smaller cities like Buffalo, New York and Fort Collins, Colorado. Personal rapid transit is a scheme that has been discussed, in which small, automated vehicles would run on special elevated tracks spaced within walking distance throughout a city, and could provide direct service to a chosen station without stops. However, despite several concepts existing for decades personal rapid transit has failed to gain significant ground and several prototypes and experimental systems have been dismantled as failures.
Private transport
Unmotorised
The private transport with the highest modal share, worldwide that is unmotorised, is pedestrianism followed by cycling.
All of these alternative modes of transport pollute less than at least the petroleum-powered car and contribute to transport sustainability. They also provide other significant benefits such as reduced traffic-related injuries and fatalities, reduced space requirements, both for parking and driving, reduced resource usage and pollution related to both manufacturing and driving, increased social inclusion, increased economic and social equity, and more livable streets and cities. Some alternative modes of transportation, especially cycling, also provide regular, low-impact exercise, tailored to the needs of human bodies. Public transport is also linked to increased exercise, because they are combined in a multi-modaltransport chain that includes walking or cycling. According to the MIT Future Car Workshop, the benefits of possible future car technologies not yet in widespread use over these alternatives, would be:
Increased mobility in rural settings and in some other areas where traffic jams are not severe
Possibly higher social status
Overall a better provision for privacy
Profit for the multinational firms producing cars, and possibly for their employees
