METHOD FOR DEVELOPMENT OF A MASS TRANSIT EVALUATION MODEL BASED ON SOCIAL SYSTEM VALUES

THIS PAPER DESCRIBES A METHOD IN TRANSPORTATION SYSTEMS ENGINEERING THAT PROVIDES A MEANS OF IDENTIFYING THE CUSTOMERS, OR DECISION-MAKERS, AND THEIR WANTS. THE METHOD WAS DEVELOPED AND APPLIED TO THE HYPOTHETICAL EXAMPLE OF A PEOPLEMOVER FOR DOWNTOWN LOS ANGELES. THE APPROACH COUPLES THE METHODOLOGY OF SYSTEMS ENGINEERING WITH UTILITY THEORY AND SURVEY TECHNIQUES. IT INCLUDES STEPS TO IDENTIFY NEEDS, CHARACTERIZE SYSTEMS, ESTABLISH PERFORMANCE CRITERIA, IDENTIFY DECISION-MAKERS AND THEIR CRITERIA, IDENTIFY THE IMPLEMENTATION PROCESS, AND GENERATE THE EVALUATION MODEL. IN THE EXAMPLE, 4 BASIC GROUPS OF DECISION-MAKERS WERE IDENTIFIED: GOVERNMENT TECHNICIANS, GOVERNMENT MANAGERS AND PUBLIC OFFICALS, LOCAL BUSINESSMEN, AND POTENTIAL RIDERS. QUESTIONNAIRES, TAILORED FOR EACH GROUP, PROVIDED WEIGHTINGS OF THE DECISION-MAKER'S INFLUENCE, DELEGATION OF RESPONSIBILITY, CRITERIA FROM THE GENERAL DOWN TO THE COMPONENT LEVEL, AND UTILITY DATA POINTS FOR ALL SIGNIFICANT COMPONENT CRITERIA. RESULTS WERE FORMULATED INTO A COMPOSITE VALUE MODEL THAT WAS USED TO GENERATE BOTH A TABULAR AND A COMPUTERIZED EVALUATION MODEL BASED ON CORRESPONDING PERFORMANCE CRITERIA AND MEASURES. THE METHOD PROVIDES IDENTIFICATION OF THE SOCIAL SYSTEM DECISION-MAKERS, THEIR NEEDS AND INFLUENCE, AND A MEANINGFUL CORRELATION AND TRANSLATION INTO TECHNICAL CRITERIA. THE RESEARCH SHOWS THE EFFECTIVENESS OF UTILITY CURVES BOTH AS A QUANTITATIVE MEASURE OF PERFORMANCE FOR A GIVEN CRITERIA AND AS A MEANS OF COMBINING WORTHS OF MULTIDIMENSIONAL CRITERIA. /AUTHOR/
