Trip Generation Models.# of trips attracted to a certain area or generated in a certain ,Dy: trip endsOx= # of trips produced (generated) at zonex(production zone)Dy= # of trips attracted to zoney(attraction zone)Dr. Anna NagurneyFOMGT 341 Transportation and Logistics - Lecture 12. Trip Distribution s andDy s find the O/D travel demand then know how many travelers fromOxwill go toDy; for allx,ypair.
