TRCPM Corradino Renaissance Planning Group Cambridge Systematics SERPM 6 Corradino AECOM Consult Consultant Teams • With thanks to … • FDOT Districts 4 & 6 • MPO staffs of Palm Beach County, Broward County, Miami-Dade County, Martin County, St. Lucie County and Indian River County • SFRTA 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. Florida Model Task Force Corradino
2000 Treasure Coast Regional Planning Model (TCRPM) • Cube Voyager based model • Covers three counties • Indian River • St. Lucie • Martin • Two Flavors • Highway – Only • With Transit 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 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 • 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 Florida Model Task Force Corradino

TCRPM RMSE Florida Model Task Force Corradino
SERPM - History • Earlier FSUTMS/Tranplan Versions: 1 - 5 • 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 Florida Model Task Force Corradino
SERPM 6 • Palm Beach, Broward and Miami-Dade Counties • 4,134 TAZs (ZONESA) • 3 Time periods (AM 6:30-9:30, PM 3:30 – 6:30, Off-peak) • 10 Transit modes • 22 – 28 hours run time on 3.4 GHZ computer Florida Model Task Force Corradino
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 What’s New? Florida Model Task Force Corradino
Setup controls and file names External – EE by period Trip Gen – LSGEN by auto ownership and TOD Highway – Including speed and capacity calculators Distribution – Including equilibration of peak period highway speeds Transit Nets – PT Trnbuild and connectors, paths, skims and fares Mode Choice Transit Assignment by access path and TOD Highway Trip Tables – Combines trip tables for assignment Highway Assignment – by TOD (use most computer time) Highway Evaluation – HEVAL and RMSE by TOD and county SERPM 6 – Model Flow Florida Model Task Force Corradino

Time of Day • FSUTMS uses auto speeds from 24-hour assignment as for HBW mode choice • HBO & NHB use free-flow speeds • SERPM6 uses time of day • Peak period trips use AM congested speeds • Off-peak period trips use free-flow speeds • Standard FSUTMS design expected for most models Source: AECOM Consult Florida Model Task Force Corradino
PT Overview • Multi-path algorithm • Can produce two or more paths per O/D pair • Skims reflect weighted values of all paths • Advanced fare system & transit speed features • Good network features • Has ability to generate access connectors Source: AECOM Consult 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 • 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 Florida Model Task Force Corradino
FDOT Central Office Research • Citilabs added a best-path switch in PT • Addresses FTA’s New Starts quality control tests • Mimics single-path path-builders • Developed and tested 3 prototype models • (1)PT multi-path (2)PT best-path (3)PT-TRNBUILD hybrid • Purposes: • Provide empirical data to assist with FTA/Citilabs discussions • Help determine best design for PT model that produces explainable results that are sufficient for New/Small Starts analysis • Identify any issues as early as possible • Developed modeling standards (“frameworks”) for multi-path system, adjusted slightly for other 2 systems Source: AECOM Consult Florida Model Task Force Corradino
SERPM 6 - TRNBUILD • Could not wait for PT “best path” • Single-path builder from TP+ & available in Voyager • Link-based, some similarities to Tranplan’s path-builder • Well-known to FTA • Reliable history that dates back to MINUTP • Used nationwide • Atlanta, Washington DC, Columbus OH, Northern NJ • Can read Voyager highway networks directly • Easy to convert PT network & connectors • Only being used in Florida for SERPM6 • Future development not supported by Citilabs Source: AECOM Consult Florida Model Task Force Corradino
SERPM 6 – Mode Choice Applied for Peak and Off-peak Florida Model Task Force Corradino
SERPM 6 – Transit Assignment • By TOD (AM, Off-peak) • By Access Mode (Walk, Auto) • By Transit Mode • Bus • Metrorail • Tri-Rail • New Mode Florida Model Task Force Corradino
SERPM 6 – Highway Assignment • By Time-of-Day • AM Peak • Off-Peak • PM Peak • Composite 24 Hours (add preceding) Florida Model Task Force Corradino
SERPM 6 – Highway Evaluation • SUMMARIES BY: • SERPM 6 Region by Time-of-Day • Each County for 24 hours • Trucks alone – each County for 24 hours Florida Model Task Force Corradino
SERPM 6 - Validation • Standard FSUTMS • +++ Plus Speed Validation • Speed compromises made in favor of Volume/Count • Good Volume/Count ratios • Very good RMSE • Good transit assignment results Florida Model Task Force Corradino
