How To Make Good Organized Transportation Planning

As has been indicated earlier, even the simplest decisions about either rural or urban transportation have ramifications beyond those on users or others who are directly affected. Some of the other functions that are impacted are listed around. Notice that the figure indicates that the single-system decision process goes on in each of the areas indicated. It would also be employed when evaluating the combined impacts.

 A useful guide to thinking in several regards. First of all, the maze of lines indicates the many interrelationships that must be explored if all implications of all public decisions are to be investigated. Secondly, it sug­gests the two-way nature of the decision-making process. For example, trans­portation decisions such as the level of funding determine the accessibility and cost of developing potential resources such as energy. On the other hand, a de­cision to develop an energy source, for example coal, affects not only plans for transportation, but also economic and social well-being, environment and health, housing, and other concerns. On the urban scene, decisions about trans­portation affect almost every other activity shown on the chart.

 To date, we have little knowledge and almost no quantifiable measures of most of these ripple effects or of one on the others. A further complication is that the systems  are dynamic and not static over time. Some of the responses to change come quickly, but others stretch over a decade or more. Suggest that by this form of planning it is possible to determine a best action or set of actions, the true situation is that even single-system decisions are seldom the optimum ones, and means for over­all system optimization are far in the future.


 More specifically to the economic and other impacts of highways, and provide a useful checklist of the factors that must be consid­ered. Although the study from which they were taken was for urban freeways, with a few additions and some change in emphasis they could be applied to almost any highway or transit system, urban or rural, in the United States or to any other nation where the broader problems of the relationships between over­all economic development and land access must be considered.  Although, with certain exceptions, units in which the various effects can be ex­pressed are suggested, there is serious question that many of the community fac­tors listed there can be measured accurately or that the proposed units are ap­propriate.
