CFRPM Overview

From Central Florida Regional Planning Model
Jump to navigation Jump to search

The Central Florida Regional Planning Model, Version 7 (CFRPM 7) is a system of processes and demand models designed to accurately reflect the transportation network and demand for 11 Florida counties: Brevard, Flagler, Indian River (northern half only), Lake, Marion, Osceola, Orange, Polk, Seminole, Sumter and Volusia.

Region Information[edit]

Geography[edit]

CFRPM 7 Modeling Coverage Area

The Central Florida region is bounded by the Atlantic Ocean on the east, the Sumter, Polk and Marion County boundaries on the west, the Marion and Flagler County boundaries on the north, and the Osceola, Polk and Indian River County boundaries to the south. The region includes all nine counties inside District 5 of the Florida Department of Transportation: Brevard, Flagler, Lake, Marion, Osceola, Orange, Seminole, Sumter and Volusia; the region includes Polk County from District 1 and the northern half of Indian River County from District 4. Throughout the CFRPM area, the suburban and rural areas are generally separated by environmental preserves or park lands that prohibit large-scale development.

Transportation System[edit]

The surface transportation system consists of roadways, bus transit, and SunRail commuter rail with the primary air transportation system in the Orlando International Airport (MCO). Roadways include eight limited-access facilities and varying types of arterial and local roads. Bus transit is provided in every county except Flagler and Sumter. The Orlando International Airport is one of the top ten airports in the country with over 50 million passengers annually.

Travel Patterns[edit]

CFRPM 7 Travel Patterns

The Central Florida region produces an estimated 16 million person trips a day, generating 11 million vehicle trips and 116 thousand transit boardings. The 16 million person trips generates over 142 vehicle-miles of travel (VMT) in Central Florida per peak season average weekday which requires 4 million vehicle-hours of travel (VHT).

Central Florida is expecting very strong growth in population and employment over the next 30 years. The population is expected to grow 51%, with every county experiencing at least a 27% increase. These socio-demographic changes will cause a corresponding increase in transportation demand. Trips are expected to increase by 56% to over 25 million trips per day, and VMT is expected to grow by 51%.

From a “big picture” transportation demand perspective, CFRPM needs to help stakeholders on decisions about:

  1. expanding transportation capacity and options to maintain pace with population and housing growth,
  2. creating new roadway networks in transitioning areas, and
  3. easing congestion and transit travel times for mature or built-out areas.

Model Overview[edit]

Model Components[edit]

Model Component Interaction

The CFRPM 7 model is design to reflect the conditions demonstrated by the Central Florida Region. It consists of three major components:

  • a Geographic Information System (GIS)-based interface for editing, visualization and reporting of the roadway network and socio-economic data;
  • a primary travel demand model that consists of trip generation, distribution, mode choice and assignment steps;
  • and a dedicated transit-only demand model that estimates public transportation ridership.

Only the primary travel demand model directly interfaces with the GIS and transit-only components. The other two components only directly interface with the primary travel model.

Model Features[edit]

The Central Florida Regional Planning Model (CFRPM) is a traditional four step model that includes trip generation, trip distribution, mode choice and traffic assignment. Additional components that are included in the model include a household disaggregation model which develops household distributions required by the trip generation as well as separate truck and external models as well as a tourism attraction component.

There are two forms of the model depending on the desired application of the model:

  • the daily model or
  • the Time-of-Day Model (TOD) that includes four periods: AM peak (7:00am to 10:00am), midday (10:00am to 3:30pm), PM peak (3:30pm to 6:30pm) and overnight (6:30pm-7:00am)

The most recent version of the CFRPM is the Official 2040 LRTP Version – 6.0- Released January 2016 with bug fixes and revisions it was re-released as version CFRPM6.1 on December 14, 2016.

On-Going Efforts/Upcoming Releases[edit]

CFRPM 7.0 is currently being developed and will be released in early 2021. This will be the model-of-record used for the 2045 Long Range Transportation Plans (LRTP) developed by local Metropolitan Planning Organizations (MPO). It will have a 2015 Base year and a 2045 Horizon year as well as interim years in 5 year increments. It will be a Time-of-Day model that includes four time periods. This will be the only available version; a daily-only model will no longer be available.

Previously, MetroPlan Orlando, the Metropolitan Planning Organization (MPO) for the greater Orlando area, created a separate travel demand model that overlapped with CFRPM. This model, the Orlando Urban Area Transportation Study (OUATS) model, is no longer produced. CFRPM 7.0 and future versions will be the definitive travel demand model for the Orlando region and greater Central Florida.

CFRPM Derivatives[edit]

CFRPM is used to derive travel demand models for partner agencies. CFRPM is taken and modified to create a model to meet the needs of each respective agency. Those models include:

  • Turnpike Statewide Model (TSM)
    • This model is created by Florida's Turnpike Enterprise (FTE), a division of the Florida Department of Transportation (FDOT). This agency maintains Florida's Turnpike, as well as other toll roads across the state.
  • CFX Model

These models are created primarily to model toll roads, which have unique modeling needs than non-toll roads.

For any additional information regarding these models, please contact the respective agency.
