RELATIONSHIPS BETWEEN DRIVERS' ATTITUDES TOWARD ALTERNATE ROUTES AND DRIVER AND ROUTE CHARACTERISTICS

DRIVERS REASONS FOR CHOOSING ONE TRIP ROUTE OVER ANOTHER ARE RELATED TO DRIVER AND ROUTE CHARACTERISTICS. DATA ARE OBTAINED FROM HOME INTERVIEWS. TESTS ARE MADE TO DETERMINE WHETHER THE IMPORTANCE OF REASONS CITED DIFFERS WITH THE TYPE OF TRIP. FACTOR ANALYSIS IS USED TO DETERMINE WHETHER RESPONSES ABOUT DIFFERENT REASONS FOR ROUTE CHOICE ARE MEASURING THE SAME OR DIFFERENT UNDERLYING VALUES. ATTITUDES ARE EXAMINED TO DETERMINE WHETHER THEY ARE INFLUENCED MOST STRONGLY BY SOCIO-ECONOMIC CHARACTERISTICS OF THE DRIVERS OR BY PERFORMANCE CHARACTERISTICS OF THE ROUTES. CANONICAL CORRELATION METHODS, REGRESSION ANALYSIS AND GROUPING TECHNIQUES ARE USED FOR A STATISTICAL EXPLANATION OF ATTITUDES, IN TERMS OF DRIVER AND ROUTE CHARACTERISTICS, TO FIND HOW STRONGLY THE VARIABLES ARE INTERRELATED.
