PLANNING URBAN TRANSPORTATION SYSTEMS: A MODEL FOR GENERATING SOCIALLY DESIRABLE TRANSPORTATION NETWORK CONFIGURATIONS

THIS STUDY REPRESENTS AN EFFORT TO DEVELOP A MODEL CAPABLE OF DESIGNING A NEW TRANSPORTATION NETWORK OR IMPROVING AN EXISTING ONE, FOR THE ACHIEVEMENT OF A GIVEN SOCIAL GOAL, IN THIS CASE AN INCREASE OF AN INDEX CALLED SATISFACTION LEVEL. THIS INDEX IS A FUNCTION OF OPPORTUNITY (TRANSPORTATION ACCESSIBILITY OR OF EMPLOYMENT) AND SOCIOECONOMIC STATUS. THE MODEL IS STRUCTURED TO PRODUCE A TRANSPORTATION NETWORK DESIGN THAT HAS A HIGHER AND MORE EQUITABLE DISTRIBUTION OF THE SATISFACTION LEVEL INDEX THAN A GIVEN BASELINE DISTRIBUTION. THE DESIGN PROCESS IS GUIDED BY A WEIGHTING FUNCTION WHICH IS A PUBLIC POLICY DETERMINATION. IT GIVES PEOPLE WITH A LOW LEVEL OF SATISFACTION PROPORTIONATELY MORE WEIGHT THAN THOSE WHO ARE PRESENTLY HIGHLY SATISFIED. THE TRAVEL DESIRES OF THIS WEIGHTED POPULATION DISTRIBUTION ARE THEN USED TO GUIDE THE DESIGN OR IMPROVEMENT OF THE TRANSPORTATION NETWORK. SEVERAL EXPERIMENTS WERE DESIGNED AND IMPLEMENTED TO TEST SOME OF THE CONCEPTS INVOLVED AND TO DETERMINE THE SENSITIVITY OF THE MODEL TO CHANGES IN SOME OF ITS KEY PARAMETERS. THE EXPERIMENTAL RESULTS SHOW THAT THE MODEL DOES PRODUCE HIGH PERFORMANCE NETWORK DESIGNS UNDER A WIDE VARIETY OF CONDITIONS AND OVER A WIDE RANGE OF PARAMETER VARIATIONS. /AUTHOR/
