SOCIOECONOMIC FACTORS AND THE HIGHWAY DECISION PROCESS

THE SOCIOECONOMIC FACTORS ASSOCIATED WITH DECISIONS IN HIGHWAY LOCATION AND DESIGN ARE DISCUSSED. COMMUNITY DESIRES MUST BE TAKEN INTO CONSIDERATION, AND THE HIGHWAY SHOULD BE FITTED TO THESE DESIRES, IF LOSSES IN MOTORISTS' BENEFITS DO NOT EXCEED GAINS TO THE COMMUNITY. THERE IS SOME TRADE-OFF OF GAINS NECESSARY BETWEEN MOTORISTS AND COMMUNITY IN ORDER TO PERMIT ACHIEVEMENT OF THE MOTORISTS' OBJECTIVE OF IMPROVEMENTS IN HIGHWAY FACILITIES. THE FACTORS WHICH SHOULD BE CONSIDERED ARE BRIEFLY SUMMARIZED: (1) BASIC COMMUNITY ATTITUDES TOWARD CHANGE MUST BE IDENTIFIED AS EARLY IN THE ROUTE LOCATION PROCESS AS POSSIBLE, (2) IT MAY NOT BE POSSIBLE, OR PRACTICAL, TO IDENTIFY EVERY POTENTIAL SOCIOECONOMIC EFFECT OR COMMUNITY VALUE, BUT ONLY THOSE KEY ISSUES THAT MAY CAUSE ADJUSTMENT IN LOCATION OR DESIGN OF THE BEST CHOICE SELECTED ON A RATIONAL BASIS, (3) SUBJECTIVE EVALUATIONS OF THE RELATIVE IMPORTANCE OF SOCIOECONOMIC FACTORS AND POINT-GRADING SYSTEMS ARE NEARLY VALUELESS AND MAY BE INIMICAL TO RATIONAL DECISION, (4) SOCIOECONOMIC FACTORS CANNOT BE WEIGHED IN HIGHWAY ENGINEERING ECONOMY STUDIES BUT SHOULD BE IDENTIFIED AND QUANTIFIED IN MONEY TERMS OR DESCRIBED AS TO POTENTIAL EFFECT WHEN NECESSARY TO AID IN A DECISION TO ACCEPT LOWER NET BENEFITS, AND (5) THE DECREASE IN, OR DEFERMENT OF, NET BENEFITS BY REASON OF COMMUNITY-REQUESTED LOCATION OR DESIGN ADJUSTMENT MUST BE CAREFULLY CALCULATED. THE RELATIONSHIPS BETWEEN COMMUNITY ATTITUDES, ECONOMIC CONDITIONS, AND OBSERVED CHANGE ARE A MATTER OF GREAT CONCERN, AS IS ALSO THE PLACE OF THE HIGHWAY IN THE CHANGE PATTERN.
