TBEST Why, What, and How
The TBEST Framework for Data Analysis and Forecasting Rodney P. Bunner
October 16, 2013 l Public Transit Modeling
Center for Urban Transportation Research | University of South FloridaAgendaMotivation and UseGIS SpecificationsTBEST Framework ComponentsData ManagementData InteroperabilityData RequirementsModel EngineAnalysis and ReportsNext StepsMotivationFDOT/planners wanted a software tool for short-term transit service planning designed specifically for transit.Serve as FDOT provided ridership estimation technique for State mandated Transit Development Plans (TDPs)Transit Boardings Estimation and Simulation Tool (TBEST) has been in production for several years and is on its 4th Major Version (4.1).FDOT is continually supporting the improvement of TBEST.
TBEST in FloridaMajor Benefits:Standardized modeling method to ensure consistency and equity among agenciesTBEST reduces burden on FDOT for evaluating a variety of ridership estimation methodologiesTBEST reduces burden on agencies to prepare and conduct more expensive and complex modeling effortsLeverage TBEST data and software framework to support multiple transit agency tasks:

Components Data ManagementTBEST manages data specific to individual transit systemsEach transit system is composed of scenarios which contain editable routes, segments, stops, socio-economic data and network attributes Validation specific to each transit systemAll GIS/database files managed internallyDownload pre-formatted SE data, transit systems and model definition packagesEasily create current or future year scenarios
TBEST managed Transit SystemsComponents Data ManagementTBEST User Interface
Components Data InteroperabilityGTFS ImportImported networks for FL agencies with GTFS feedsUtilized nationally in Ft. Worth, RVTD, Los Angeles, SavannahGTFS ExportExport TBEST planning network into GTFSAdded TBEST attributes to exported data including ridership and stop amenitiesArcGISExport TBEST maps and data into ArcGISImport route alignments into TBEST from outside data sourcesExport loaded networks into geodatabases
Components Data RequirementsOriginal Data RequirementsCensus 2000
EmploymentFDOT provided InfoUSA address-based data
Manually coded Route Network
Special Generator SpecificationCurrent Data RequirementsCensus 2010American Community Survey
EmploymentFDOT provided InfoUSA address-based dataOptionally include locally provided zonal dataLand UseFlorida Department of Revenue parcel dataITE Trip Generation Tables
GTFS network import and full network editorSpecial Generator and Stop Amenity Specification
Components Model EngineMicro-level model which simulates transit ridership at the level of the individual stop: by route, direction and time period Designed to capture both walk access market and network accessibilityModel equations estimate direct and transfer boardingsAccommodate service features of fare, speed, frequency, etc.Accommodate fundamental differences in route types (local, circulator, express)Automated Validation Users supply observed ridership and TBEST calculates model application adjustmentsallows TBEST to adapt to different urban locations without developing new model equations (transferable)
Components Model EngineMultiple Model Management Users are able to maintain multiple model structures which can be applied to model scenarios
Editable Model Structures Users can add, delete or modify coefficients, land use trip rates, and network and market accessibility parameters
Available ModelsComponents Model EngineBRT Sensitivity - Users specify the implementation level of specific route-level BRT characteristics and TBEST will adjust base ridership forecasts with an empirically derived adjustment factor
Components Analysis and ReportsStop, Segment, Route and Regional distribution reports with supporting maps
Components Analysis and ReportsScenario Comparison and Mobility Threshold service recommendations
Components Analysis and ReportsTDP Summary Report - Summarizes annual service area pop, employment, performance, and service for all scenarios in a TBEST transit system
