Operating Urban Transportation Engineering - Part 1
Generalizations
based on average statistics transportation engineering such as those given above, although they portray
the overall situation, must be viewed with caution in evaluating individual
situations. For example, in the United States as a whole, motor vehicle
ownership, averaging about 1 for every 1.8 persons, ranges from about 1 for
every 1.3 in predominately rural states to 1 for every 2.8 in the District oi
Columbia, which is almost wholly urban. In major European cities these ratio?
range from 1 to 3.2 in Munich to 1 in 5.2 for Copenhagen. London is 1 to -4.7.
Certainly
availability of an automobile affects transit use. Again, 70% o; the nationwide
work trips are by auto; but for the larger, older, and denser urban areas,
transit work trips are far more numerous. The 1970 census shows work trips by transportation transit as follows: New York, 61%; Boston, 38%; Philadelphia, 37%; and Chicago,
36%. These cities all have rail as part of their system. At the other extreme,
work trips by transit were 18% in Detroit, 9% in Los Angeles, and 8% in Houston.
Data for the San Francisco Bay area taken soon before the 1979 gasoline
shortages and price increases show rail rapid transit (BART) carrying 5% of
the to-and-from-work movements, buses and street cars 18%, and motor vehicles
77%. Transit use in the 14 largest metropolitan areas accounts for 70% of the
nation's transit passengers, and New York alone accounts for 38%. These
percentages are much lower for the more than 400 all-bus svstems operating in
the urban transportation areas which have populations over 500,000 and the more than 500
systems in smaller communities.
