                        GOAL IDENTIFICATIO




TRAFFIC PLANNING GOALS
must be determined by the in-
stallation decisionmakers, with
the assistance of technical ex-
perts.     Technical      experts
should provide direction for the
decisionmakers           through
rational analysis of installation
needs and policies. With this
information,     decisionmakers
can effectively     select goals
and a planning program that
will insure an end product that
is both workable and desirable.

      EFFECTIVE THOROUGHFARE PLANNING requires concerfed efforf among policymakers                       and the
      technical and administrative   staffs of the installation under study. Each step of the planning process
      must be based on a simple framework in which the installation’s        decisionmakers   can clearly under-
      stand not only the traffic problems, but also the solution to those problems. Committee members
      usually should be selected to represent the installation’s     diverse disciplines and viewpoints. For ex.
      ample, an individual representing each of the groups shown below would be desirable.

THE    FIRST   STEP     IN THOROUGHFARE
PLANNING     is to clearly identify all traffic
problems of the installation being studied.

The term “traffic problem” is defined as any
situation that impairs the sate and efficient
flow of traffic
                                                   FOR EVERY TRAFFIC   PROBLEM,   THERE   IS
In identifying traffic problems. relativity must   A POSITIVE GOAL
be considered; that is, traffic problems vary
among different areas of the country. For ex-
ample, a 5.minute delay in New York City is
considered     as negligible,  while the same
delay in Timbuktu         would be extremely
frustrating to motorists. Therefore, it must be
remembered that traffic problems are relative
to the installation   being studied.

                                                         congestion primarily because of wasted time
                                                         and the resulting increased operating costs.
                                                          Excessive operating costs can be measured
                                                          with a fair degree of precision. For example,
                                                          on a l-mile free-flowing roadway of 30 miles-

                                                           However, evidence       shows that, given a

ACCIDENTS        - Accidents are
the most significant of all traf-
fic problems.       In 1983 alone,
approximately        52,000 motor
vehicle accidents occurred on
military     installations,      and
resulted in an estimated cost
of $117 million to DOD and its
personnel. Recent surveys of
military installations      revealed
that the yearly accident rate
 ranged from 1 to over 95 per
 1,000 people. This wide range
 indicates    that the accident                           ACCIDENT COST TO DOD

                            BE AWARE OF CONFLICTS BETWEEN GOALS

                           Simply having an agreed set of goals and objec-
                           tives is not enough because of the conflicts
                           between goals. For example, the least expen-
                           sive, initially, is to do nothing; whereas, the
                          safest could very likely be the most expensive.
                           Basically, goals should be listed and then
                          screened to eliminate all but the most relevant.
                          The goals selected should then be related to
                          each other, so that losses toward one goal
                          could be offset by gains toward another. Finally,
                          these goals should be related to minimizing the
                          total transportation costs.
