1 no stops on ether outbound or inbound direction; 2 one outbound stop leg, no inbound stops; 3 no outbound stops, one inbound stop; and 4 one stop in each direction. The proposed stop location choice model is also a multinomial logit construct. Similar to the destination- choice model, the stop- location model requires a proce- dure for selecting a limited subset of relevant zones (for both model calibration and application) to reduce com- putational burden. In the case of the stop- location model, however, both origin and destination of the jour- ney are known; thus, effective rules were applied to build a âspatial envelopeâ that reflects the observed travelerâs behavior. The current version of the NYMTC model has a time- of- day choice model based on a set of predetermined time- of- day distributions segmented by travel purpose, mode, and destination area. One of the ongoing works of PB Consult for further enhancement of the NYMTC model includes replacement of the time- of- day distribu- tion with a time- of- day choice model sensitive to person, household, and level- of- service variables. Time- of- day choice is followed by trip mode choice (in most cases predetermined by the entire- tour mode) and a preassign- ment processing procedure that constructs mode- specific and period- specific trip tables. In the period from 2002 to 2006, the New York model had been used by NYMTC for more than 30 local planning agencies for various projects, including envi- ronmental conformity analysis, a Tappan Zee bridge study, a Goethals bridge study, a Manhattan, New York, area pricing study, and many others. Since 2002, PB Consult has been constantly supporting NYMTC and the other users through an ongoing model support con- tract with NYMTC. 23DEVELOPMENT OF NEW YORK TOUR- BASED MODEL
