Southeast Florida Regional Planning Model, Version 6.5 (SERPM 6.5) Model Update Procedure
SERPM 6.5 was constructed for the development of 2035 Miami-Dade, Broward, and Palm Beach Regional and MPO Long Range Transportation Plans. The base year model was calibrated to 2005.
The Modeling Subcommittee (MSC) of the Regional Transportation Technical Advisory Committee (RTTAC) of the Southeast Florida Transportation Council (SEFTC) is the oversight entity of this SERPM Model. The MSC actively coordinated the modeling effort while the MPOs were developing the 2035 R/LRTPs and is responsible for the continuing updates of the model to reflect the evolving of the plans. MSC also serves as the peer-review entity for SERPM 6.5 applications should any SERPM6.5 users wish to have a model application peer-review they should contact the MSC Chair: Mr. Wilson Fernandez, (305-375-4507, wilson@miamidade.gov)
The Cost Feasible SERPM 6.5 update contains one model execution processes, two zonal data sets, and two networks:
Modeling Processes: The Time-of-Day (TOD) process models three Highway assignment time periods for AM Peak, PM Peak, and Off-Peak and two Tranist assignment periods for Peak and Off-Peakt. This process is designed for testing alternatives with transit and/or with the managed lanes. It should also be used for highway analysis when peak-period /peak hour operations are a concern and/or the model outputs will be used as a source for dynamic traffic assignments or micro simulations.
Zonal Data: Two sets of zonal data are available:
- 2005: Model calibration year
- 2035: Population, Employment, School Enrollment and other TAZ data sets of the adopted R/LRTPs
Network: Two sets of Highway and Transit Networks:
- 2005: for base year model validation
- 2035: Adopted Cost-Feasible R/LRTP network
It is anticipated that the model will be updated regularly in order to reflect the latest amendments to the R/LRTPs, land use plan, and/or to correct detected errors.
Model Updates: The model will be updated in the following coordinated manners:
R/LRTP amendments:
- The MPO staff will initiate the network and/or the zonal data updates as soon as the amendments have been formally adopted by the MPO board. MPO staff will coordinate with Mr. Yongqiang Wu, (954-777-4653, Yongqiang.wu@dot.state.fl.us), FDOT District 4 Model Coordinator on these update and the release of the updates.
- Coding errors: Please report directly to Derek Miura if you found any errors. Reference for proper corrections are essential and appreciated
Modeling Process Update:
- There are continuing efforts to refine the modeling process to reflect the latest understanding of travel behaviors, to incorporate latest software enhancements, or for other reasons. Roll out of these updates will be announced on https://www.fsutmsonline.net and the SERPM users will be notified. Model output differences between the new release version and its immediate predecessors and between the new release and the 1st version will be documented and posted on https://www.fsutmsonline.net.
- Update Log: The update log of the model will be placed on https://www.fsutmsonline.net and will be distributed with the model download package.
As one of the most complex FSUTMS models, SERPM is expected to be used by modelers with sound understanding of modeling principles, good insights on modeling interpretations and proficiency on modeling software.
Model Support: In case the support is needed, Modelers should:
- Consult Cube/Voyager On-line documentation for software functionalities and/or Citilabs for issues related to software, Cube/Voyager installation and license.
- Contact Vladimir A. Majano, (850- 414-4931, vladimir.majano@dot.state.fl.us) at FDOT Central Office on general FSUTMS support, including training.
- Refer to SERPM 6.5 Technical Reports Model Data, Calibration and Validation and Model Application Guidelines to familiar with the structure and processes of SERPM. These documents are available from FSUTMS Online.
- Contact Yongqiang Wu (954-777-4653, Yongqiang.wu@dot.state.fl.us) at FDOT District 4 for SERPM specific questions.
- Contact Wilson Fernandez (305-375-4507, wilson@miamidade.gov) at Miami-Dade MPO on model application peer review consultation.
