3December 12, 2006 Florida Model Task Force Corradino TCRPM - History Earlier FSUTMS/Tranplan Versions: 1 & 2 TCRPM 3 – Highway-only model developed and calibrated completely in TransCAD … thought we were done! Model development switched to Cube Voyager after Model Task Force action in the fall of 2004.

5December 12, 2006 Florida Model Task Force Corradino TCRPM – What’s New? Cube Voyager Platform Initial Speeds from Posted Speed and Traffic Signal Data on the network PT for a simple transit network Matrix for Mode Choice Highway Evaluation Connected to standard FSUTMS RMSE and HEVAL programs

6December 12, 2006 Florida Model Task Force Corradino TCRPM Uses FSUTMS Facility and Area type coding Trip generation rates are county specific Mode choice model Splits auto and transit trips Splits auto and transit trips Further splits auto trips in occupancy levels Further splits auto trips in occupancy levels Run time for the full model is 7 min. on a 3.4 GHZ machine Traffic Analysis Zones = 731

9December 12, 2006 Florida Model Task Force Corradino SERPM - History Earlier FSUTMS/Tranplan Versions: SERPM 5 – 1999 Base Year with restructured mode choice responding to FTA concerns SERPM 6 is a Cube Voyager model, no Tranplan required. Custom-written Fortran code for LSGEN, Mode Choice and a few other minor components

11December 12, 2006 Florida Model Task Force Corradino What’s New? Zdata in TAZ Shape file DBF 3 Period Time-of-day Dynamic area types Estimation of initial speeds from posted speed and signals 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 estimation of kiss-and- ride and park-and-ride at stations

17December 12, 2006 Florida Model Task Force Corradino FTA Reactions to PT Strongly recommended micro-coding fixed-guideway, park-and-ride & kiss-and-ride stations to better represent transfer time Existing FSUTMS standards utilize same node for rail & bus stations Existing FSUTMS standards utilize same node for rail & bus stations Confirmed that multi-path builder is not compatible with existing FSUTMS mode choice structure PT v4.0 can not provide the necessary information for New Starts quality control tests Trying to quantify impacts of multi-path systems on New/Small Starts; would prefer single-path but do not require it Helpful to have empirical evidence of typical New/Small Start situations in PT Source: AECOM Consult
