The TBEST Framework for Data Analysis and Forecasting

September 17, 2013
Center for Urban Transportation Research | University of South Florida
Transit Boardings Estimation and Simulation Tool
Transit Demand Modeling/Analysis Software developed by
the Florida Department of Transportation Office of Freight,
Logistics and Passenger Operations
Provide a “Comprehensive Transit Network Modeling,
Management and Analysis Software with a focus on short to midterm transit planning available to all Florida transit agencies”
Support Agency Transit Development Plans (TDP):
TBEST is an FDOT approved ridership estimation
TBEST Utilization
Provide workflow support for the following:
• Service Planning
• Comprehensive Operational
Analysis (COA)
• Grant Applications
Transit Planning/Forecasting Software
• FTA Title VI Analysis
Short and
• Mobility Studies
Long Range
• NTD Route Miles
• Market Analysis
• Network Accessibility

Managing Components
TBEST Transit System
• Composed of model scenarios
which contain editable routes,
stops, socio-economic data and
network attributes
• All GIS/database files managed
• Download pre-formatted SE data
• Managed Model Validation
• Customizable model structure
• Easily create current or future year
Transit Data Management
Supporting Data
Census 2010 and ACS
InfoUSA (or local zonal data)
Land Use (Parcel-Level)
Florida Department of
Download or GTFS
Special Generators
Socio-Economic Growth Rates
Bureau of Economic and
Business Research
Observed Ridership for
TBEST GIS Specifications
• Desktop application requiring ArcGIS 10.1 Basic license
• Utilizes ArcGIS Engine for map display, spatial analysis and
network editing
• ESRI personal geodatabase stores transit layers and socioeconomic data geometry
• Demographics, service characteristics, and model output
stored in SQL Server 2008 R2 (Express or Enterprise editions)
• No Network Analyst or ArcSDE required
• Utilizes ESRI Map Services, Bing Maps or preformatted .mxd
for base map
• No fee for TBEST except ArcGIS license
Model Specifications
• Micro-level model which simulates transit ridership at the
level of the individual stop: by route, direction and time
• Designed to capture both walk market and network
• Model equations estimate direct and transfer boardings
• Accommodate service features of fare, speed, frequency, etc.
• Accommodate fundamental differences in route types (local,
circulator, express)
• Model validation process allows TBEST to adapt to different
urban locations without developing new model equations
Model Equations
Users are able to maintain multiple model structures which can be applied to
model scenarios
TBEST is installed with two model structures,
the classic TBEST Model which utilizes
the Census and Employment data and
the new TBEST Land Use Model which
includes trip-generation from parcel land
use data.
Available Models
New models coming online in Los Angeles and Oregon
– LA model will include specific equations for Bus and Rail
– Oregon model will include customization of the parcel level land use
BRT Sensitivity
TBEST now supports BRT route definition and model
How it works
Users specify the implementation level of specific route-level
BRT characteristics and
TBEST will adjust base
ridership forecasts with
an empirically derived
adjustment factor
Network Interoperability
• GTFS Import
– Imported networks for all FL agencies with
GTFS feeds
– Also used nationally in Ft. Worth, Portland,
Los Angeles, Savannah
• GTFS Export
– Export TBEST network into GTFS
– Added TBEST attributes to exported data
including ridership and stop amenities
• ArcGIS
– Export TBEST maps and data into ArcGIS
– Import route alignments into TBEST from
outside data sources
– Export “loaded networks” into geodatabases

TDP Summary Report
Summarizes annual service area pop, employment, performance, and service for
all scenarios in a TBEST transit system
Market Analysis
• Works to summarize the intensity and distribution of
land use, socio-economic, and employment data for
a given transit market in a current year or future year
socio-economic setting
• Performed on existing or proposed network structure
or within specific DRI’s/corridors to determine the
viability of transit options in the area
• Independent of the TBEST modeling capabilities

FTA Title VI Analysis
Network Accessibility Analysis
• Combines TBEST transit networking origin/destination
capabilities with market and model results to produce
an interactive summarization of network accessible
markets and model output
• Network Accessibility Build - core of the accessibility
calculation which populates an origin/destination
matrix for each stop in the network
• Summarizes both outflow and inflow markets and
ridership from a selected stop, multiple stops or from
a geographic area by time of day
• Filter results by trip time and number of transfers
Network Accessibility Analysis
Network Accessible Market Analysis
Implementation Results
Win-Win-Win Situation
FDOT standardized model platform for consistent
TDP ridership reporting across agencies
Agencies have a pre-built methodology for
estimating ridership + multiple workflow support
Consultants using TBEST for TDP, COA, etc. have an
easy-to-implement ridership estimation solution
with available data, tools and modeling capabilities
Steps Underway
September 2013
– Release TBEST 4.1
– Contains online Video Tutorials
– Classroom training early 2014
January 2014
– Enhanced FTA Title VI and Environmental Justice Analysis
and Reporting
June 2014
– Parcel Editor
– Integrate Observed Ridership for COA support
October 2014
– Network Accessibility Composite Measures
