What’s New in TBEST 4.4


TBEST version 4.4 builds upon the advances in prior versions and adds new functionality to support advanced transit planning analysis and reporting.  The following features highlight the improvements within the software:


  • Compatible with ArcGIS 10.4 and ArcGIS 10.3
  • Compatible with Windows 10
  • New SQL Server 2014 LocalDB database engine with a simplified TBEST deployment
  • OpenStreetMap Base Map option is now available to reference into the TBEST Map
  • TBEST Distribution Files (.tds) have expanded file size capacity up to 4 GB.

Socio-Economic Data Updates

Florida state-wide data updates are available for download within TBEST including the following:

  • 2014 American Community Survey 5-Year Estimates
  • 2014 InfoUSA Employment data
  • 2015 Florida Department of Revenue Parcel-level Land Use

Operational and Policy Settings

TBEST now provides a single Transit System Operations and Policy Editor for defining system-level policy variables which are integral to many TBEST analytical processes and reporting output.   The settings include the Transit System service area definition, operating cost parameters, percent layover time, and Title VI parameters which support integration of local policy into TBEST Title VI reporting.  Once set, the input policy values are propagated to all of the TBEST reporting and analysis tools as the default input parameters.  With this feature, TBEST analysts no longer have to investigate local operations and policy parameters as those values are now embedded in the TBEST Transit System, saving the agency time and improving the accuracy of TBEST reporting output.  For more information, see Section 3.7 of the TBEST User Guide.

Network Editing Improvements

  • Route Realignment Tool – TBEST now provides an automated approach to realigning multiple routes using a single input segment geometry. The Route Realignment tool allows users to designate a source segment alignment and apply the alignment to other connecting route patterns. Users are able to preview the proposed realignment before executing and TBEST also provides batch realignment mode to apply the network update to multiple route patterns.  For more information, see Section 5.8 of the TBEST User Guide
  • Special Generators and Amenities – Based on user preferences and workflows, the TBEST stop-level Special Generators and Amenities are no longer assigned on a time period specific basis.
  • Many fixes and performance improvements

GTFS Interoperability

TBEST 4.4 builds upon the already robust GTFS Interoperability tools provided in prior TBEST releases.  The following updates provide TBEST users with a comprehensive set of features to be able to fully interact with GTFS files within TBEST:

  • GTFS Import Interface Improvements – the TBEST GTFS Import Tool includes a new, simplified interface to allow users to interactively define import parameters and even view GTFS service levels prior to import. Within the new interface, users can now define route segmentation options, ridership import options, and export the list of GTFS routes for evaluation prior to import.
  • GTFS Import History – to aid users in evaluating the history of a TBEST scenario network, the GTFS Import in TBEST 4.4 will now capture user-defined import options into an archive.  The GTFS Import archive contains all import parameters including the selected list of input Service ID’s, routes, service levels and a copy of the source GTFS.  Users can access the archives at any time by right-clicking on the source scenario in TBEST Explorer and selecting GTFS Import History… from the context menu.

For more information on TBEST GTFS capabilities, see Section 11 of the TBEST User Guide.

 Interactive Query

The TBEST Attribute Search Tool has been updated with a consolidated and standardized list of searchable data fields specific to route patterns, route segments and stops.  New to TBEST 4.4 is a Route Headway query field allowing TBEST users to select routes and stops operating at specified service levels.

Reporting Improvements

  • The new Applied Route-Level Validation Factors Report allows users to view the route-level validation factors applied by the TBEST ridership estimation model. This report specifically highlights factors that have been internally calculated and applied to new routes/new service.  This report provides additional insight into the “under the hood” TBEST model application.  See Section 7.6 of the TBEST User Guide for more information
  • New Scenario Comparison Tool features:
    • Improved Cost Reporting Formula – the Scenario Comparison Tool includes a more robust cost per revenue hour + cost per revenue mile formula which accommodates most agency cost estimation methods
    • Fleet Estimates – For enhanced operations planning, TBEST now provides route-specific fleet size estimations by time of day for all alternative scenarios
    • Layover Time – revenue hour estimates include a defined, agency specific percent layover time

Title VI Analysis Workflow Support Tool Updates

The TBEST Title VI Analysis Workflow Support Tool has been updated to address the need for comparative summaries of proposed service changes and to evaluate jurisdictional and Flex route areas for Title VI service equity considerations.  TBEST 4.4 introduces the following tool improvements:

  • Support for Jurisdictional boundaries and Flex route areas.
  • System, Route-Level, and Jurisdictional/Flex Route Service Change Comparison Reporting. See Section 12.7 of the TBEST User Guide for more information.
  • System-Level and Route-Level Minority and Low Income Service Reports
  • Low Income Route Designations

Title VI Disparate Analysis Workflow Support Tool

TBEST 4.4 introduces the new Title VI Disparate Analysis Workflow Support Tool.  This tool was designed to support agencies in quickly evaluating major service changes for disparate impacts to minority and low income populations.  This wizard-driven tool accepts a base condition scenario network and a service change network as inputs to calculate disparate service modification impacts against the base socio-economic conditions.  The threshold for disparate impact can be defined by the user to be consistent with the FTA 4/5ths Rule or defined based on local Title VI disparate impact policies.  The Title VI Disparate Analysis Dashboard summarizes the Weekday, Saturday and Sunday results with easily interpretable graphic reporting.  For more information, see Section 17 of the TBEST User Guide.
