ESTIMATING MULTIMODE TRANSIT USE IN A CORRIDOR ANALYSIS

A CHAIN OF MODELS, BASED ON THE UTILITARIAN THEORY OF TRAVEL MODE CHOICE, WAS USED TO REPRODUCE AND FORECAST USE ON COMPETING BUS AND RAIL FACILITIES IN A SUBURBAN CHICAGO CORRIDOR. THE MODELS WERE CALIBRATED BY DATA FROM A SURVEY AREA ENCOMPASSING ABOUT A FIFTH OF THE STUDY AREA POPULATION. NETWORKS AND TRIP TABLES WERE REDUCED FROM REGIONAL SCOPE FOR CORRIDOR APPLICATION. THE CORRIDOR-LEVEL ANALYSIS ALLOWED INEXPENSIVE TESTING OF MULTIPLE-DESIGN ALTERNATIVES. MODEL TEST EXHIBITED A SATISFACTORY ABILITY TO REPRODUCE DATA FROM STUDY AREA TRANSIT RIDER COUNTS AND SURVEYS, INCLUDING MODE SHIFTS RELATED TO INTRODUCTION OF THE SKOKIE SWIFT RAPID TRANSIT SERVICE. /AUTHOR/
