All zonal data (ZDATA1/ZDATA2/ SCHOOL/WALK) in TAZ Shape file DBF 3 Period Time-of-day & 24-Hour Highway Model 2 Period Transit TOD Model Dynamic area types Estimation of initial speeds from posted speed and signals data Estimation of capacities from roadway physical characteristics Estimation of time delays at freeway merges Equilibration of speeds in peak period pre-assignment Trips for HHs with autos distributed using highway skims, while 0-auto HHs use transit skims Micro-coding of fixed-guideway transit stations Model is validated to observed highway speeds as well as to traffic counts Transit nets kept in PT, but Trnbuild used for paths, skims and assignment Non-motorized mode choice Built-in mode choice constant estimation process Better External Trip Process for Freeways More Scrutiny of Toll Facility Data and Volumes
