Tcrpm history
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.

2000 treasure coast regional planning model tcrpm
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

Tcrpm what s new
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
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

Serpm history
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

Serpm 6
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

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

What’s New?

Florida Model Task Force

Corradino


Serpm 6 model flow

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

Time of day
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

Pt overview
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

Fta reactions to pt
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

Fdot central office research
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

Serpm 6 trnbuild
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
