CHOICE OF ROUTES ON URBAN NETWORKS FOR THE JOURNEY TO WORK

ABOUT 13,000 DRIVERS TRAVELING FROM HOME TO WORK WERE INTERVIEWED FOR THEIR DAILY ROUTES ON THE HIGHWAY NETWORK AND FOR THEIR MOTIVATIONS FOR SELECTING THESE ROUTES. THE TRAFFIC CONDITIONS AND CHARACTERISTICS OF EACH ROUTE WERE ALSO INVESTIGATED. TH RESULTS OF THESE INVESTIGATIONS AND AN ANALYSIS OF THE MOTIVATIONS SHOWED THAT TRAVEL TIME, DISTANCE, NUMBER OF POSSIBLE STOPS, AND MAXIMUM LANE VOLUME ON A LINK BETWEEN THE POINTS OF CHOICE ARE IMPORTANT FOR ROUTE SELECTION. THESE FOUR RESISTANCE FACTORS WERE USED TO DEVELOP A TRIP-DIVERSION MODEL. IT WAS FOUND THAT THE PARAMETER VALUES OF THIS MODEL DEPEND ON ROUTE DISTANCE OR DRIVING TIME AND THE TYPE OF TOWN DISTRICT TRAVERSED. OPTIMAL ROUTES IN HIGHWAY NETWORKS WERE FOUND BY DETERMINING A FORMULA FOR LINK RESISTANCE. THE FORMULA CONTAINS TRAVEL TIME, LENGTH, AND LANE VOLUME OF THE LINK AS IMPORTANT FACTORS, AND IT IS SHOWN THAT THE PARAMETERS OF THIS EQUATION ARE A FUNCTION OF THE LINK LENGTH. AN APPLICATION OF THE MODEL SHOWED GOOD RESULTS. /AUTHOR/
