1. presented to GIS Committee, Florida Model Task Force presented by Albert Gan Associate Professor Lehman Center for Transportation Research Florida International University May 14, 2010 FSUTMS Data Framework

2. Problems with FSUTMS Input Data Input data are stored in individual files of different file formats DBF, CSV, PEN, DAT, LIN, NET, MAT, etc. Text files do not have variable names Variable names are inconsistent among different models Files are not saved in standard file folders Consequence: Data are more difficult to maintain and understand Consequence: Tools cannot be developed without customizing for individual models

3. Project Objective Design a data framework for FSUTMS that facilitates the maintenance of model input data allows tools to be developed and applied across all models with minimum or no customization

4. Three Basic Design Approaches Use of geodatabase Use of “master” geodatabase Include all variables used by all FSUTMS models

5. Use of Geodatabase Store all files as a set of tables in a personal geodatabase file GIS-TM uses this approach more than 10 years ago 2 GB size limit of Personal Geodatabase is not a problem Geodatabase for all base-year data for SERPM is only 65 MB, or about 3% of the 2 GB limit

6. Use of Master Database Approach 2010 2020 20302040 Traditional Approach 2000 Master Database Scenario Extraction Scenario Merging 2010 Forward or Backward Propagation

7. Include all Variables for all FSUTMS Models Each model has all of its variables included in the data framework There is NOT a standard set of data variables in the data framework Local models will not be affected as a result of transitioning to the data framework However, each model will have to do the following: modify to standard table (was file) names, variable names, and file folders modify input scripts to read from a standard geodatabase instead of individual files

8. FSUTMS Models Considered Florida Statewide Model (FLSWM) Northeast Regional Planning Model (NERPM) Tampa Bay Regional Planning Model (TBRPM) Southeast Regional Planning Model (SERPM) Treasure Coast Regional Planning Model (TCRPM) Greater Treasure Coast Regional Planning Model (GTCRPM) Central Florida Regional Planning Model (CFRPM) Northwest Florida Regional Planning Model (NWFRPM) Gainesville Urbanized Area Transportation Model (GUATS) Polk TPO Model (POLK)

9. Project Tasks Developing standards for folder names and structure, database names, table names, field names, and field types for all input data as well as setting standards for metadata files. Designing a master database that is inclusive of all standard input data tables and fields of all modes from all scenarios of all local models. Developing a master database system that implements the master database approach. Developing a procedure for converting existing input files into the proposed master database.

11. Variable Naming Conventions 10 characters maximum Use meaningful names If a variable name contains multiple words, use underscores only if it helps to avoid confusion If a variable is used by multiple models: choose one that is most commonly used subject to the above criteria If a variable is used by only a specific model: use the original name unless they do not meet the general criteria above Reference document: FSUTMS Powered by Cube/Voyager Data Dictionary, December 2005FSUTMS Powered by Cube/Voyager Data Dictionary

13. Table Name Conventions Maintain most traditional names SPDCAP, VFACTORS, FF, PANDA, etc. No need to attach model year and model alternative; they are part of the scenario database file name Transportation-network related tables HwyNodes, HwyLinks, PtNodes, PtLinks, PtLines Non-transportation network related tables See next slide

15. Master Geodatabase File Contains all tables for all models, all networks, all scenarios

16. Scenario Geodatabase Contains only applicable tables for specific model, specific model year and model alternative

17. Metadata Standards Not metadata files currently used by any models FGDC Plus Stylesheet (Federal Geographic Data Committee) Template: http://www.fsutmsonline.net/SERPM_MASTER.XML http://www.fsutmsonline.net/SERPM_MASTER.XML Edit in Word: C:\FSUTMS\D4\SERPM\MASTER\SERPM_MASTER.DOC C:\FSUTMS\D4\SERPM\MASTER\SERPM_MASTER.DOC

20. Master Database System

21. Scenario Extraction

22. Scenario Merging: saving as a new scenario

23. Scenario Merging: update original scenario

24. Data Conversion Procedure (from existing files to master geodatabase) Step 1: Create a geodatabase for the base-year data Create an empty Cube geodatabase in Cube Import highway network Import public transit network Import TAZ feature class (optional) Step 2: Create a master geodatabase Create an empty geodatabase in ArcCatalog Import feature classes from Cube geodatabase into master geodatabase Import other non-transportation network related data

25. Data Conversion Procedure (continued) Step 3: Update master geodatabase in Microsoft Access Rename variables to standard names Add master database system tables (BaseYearNumber, ProjectInfo, ImpExpInfo) Add LineID field to PTLines feature class Add master geodatabase key fields (MNet_Year, MNet_Status, and MNet_ProjectID) to feature class and data tables Fill key fields with appropriate values

26. Master Database System Install Package Download: http://lctr.eng.fiu.edu/MasterDBS.zip (beta version, 14 MB)http://lctr.eng.fiu.edu/MasterDBS.zip Include the SERPM master database file as an example (installed to C:\FSUTMS\D4\SEPRM\MASTER\) Require ArcGIS Engine Runtime or ArcGIS Desktop installed on the computer running this application
