HIGHWAY AND URBAN
TRANSPORTATION PLANNING
The Development of Highway
Planning:
In
the United States before 1930, the primary attention of highway agencies was
focused on establishing a system of all-weather rural roads. With this
objective there seemed to be little need for “planning” the problem was to get
the roads built.
About 1930 the attitude toward
planning began to change. City streets were in relative distress, and many
rural highways were overloaded. The practice of using all federal aid and the bulk
of state highway funds for the improvement of main rural highways needed
examination. And yet what were the next most important groups of roads or
streets? Should their improvement supersede the demand for reconstruction of
much of the main system that was rapidly becoming inadequate for increased
traffic?
From the data at hand such questions
were unanswerable. To get facts on which to base decision, the so-called
“highway planning surveys” were under taken. Beginning with the Federal-Aid Act
of 1934, Congress authorized expenditures not to exceed 1 ½ % of federal-aid
funds apportioned to each state for the making of surveys, plans, and
engineering investigations of projects for future construction. In addition,
the usual “matching” provision was waived. By 1940, all the state highway
departments were assembling the facts necessary to develop long range highway-
improvement programs.
Today, planning has become a basic
activity of every major highway or transportation agency. Data assembled by the
planning departments are used to develop programs for the years ahead, and in
almost administrative decisions. New planning procedures are under continuous
development; in many of these activities, scientific applications such as
special instruments, statistical methods, and computer analysis are replacing the
cumbersome and time consuming hand-labour methods of earlier days. But in spite
of developments such as these, the planning premises and approaches of highway
agencies and the proposals for highway improvements stemming from them are
being challenged on many fronts. As a result, some projects, particularly urban
freeways, are not being constructed at all and others have been substantially delayed.
For example: a 1971 study by the Texas Highway Department indicated that an
average of 8 years and 5 mo elapsed between authorization to proceed with a
project and its opening to traffic, and even longer lead times are anticipated
when the environmental impact statements called for by the Environmental
protection Act are required.
