Webinar: Deploying ITS Standards Using USDOT Testing Tools

The U.S. Department of Transportation (USDOT) hosted a webinar April 17, 2019 to discuss deployment of interoperable transportation systems using USDOT software tools. These tools, the Test Procedure Generator (TPG) and the Center-to-Center Reference Implementation (C2C RI) are intended to fill existing gaps in ITS standards consistency, interoperability, conformance, and development of test documents.

The webinar introduces both tools and lessons learned from a local agency who deployed the Traffic Management Data Dictionary (TMDD) standard using the C2C RI tool. Please click here to download the slides.

Presentation: 2018 Institute of Transportation Engineers (ITE) Annual Meeting – USDOT Tools for ITS Standards Deployment

A presentation delivered at the ITE 2018 Annual Meeting provided an overview of the TPG and C2C RI and their benefits. Please click here for the slides.

ITE Journal July 2017: Introduction to United States Department of Transportation Tools for ITS Standards

The ITS Standards program published an article in the July 2017 ITE Journal highlighting the TPG and C2C RI Tool. To read the article please click here.

The Test Procedure Generator (TPG) Tool and the Center to Center (C2C) Reference Implementation (RI) Tool are currently unavailable due to routine testing. Please check back in 24-48 hours. (Feb. 7, 2022)

Test Procedure Generator (TPG)

TPG v3 is now available. The TPG automates the development of test procedures for NTCIP Standards.

USDOT Announces the Release of the TPG v3 Software Tool

TPG v3 updates include:

  • Compatibility with Windows 7 and Windows 10.
  • Compatibility with protected MS Word version of standards available from the Standards Development Organizations. The Word versions of 1203, 1209 and 1211 are now posted online, with more standards being added in the near future. The documents can be found here:
  • Support for deprecated and obsolete requirements, dialogs, and objects found in the standard.
  • Inclusion of XML Schema documentation for the TPG produced test procedures in XML format.
  • Compatibility with Microsoft Office 2010.
  • Minor bug fixes.

USDOT is pleased to provide the ITS Standards development and deployment communities with the updated tool. The TPG provides users with two important capabilities for the National Transportation Communications for ITS Protocol (NTCIP) Center-to-Field (C2F) Device Interface Standards with Systems Engineering Content and follow NTCIP 8002 Annex B1 formatting. These capabilities include:

  • Guiding the development of test procedures for selected requirements in NTCIP C2F standards.
  • Importing draft standards from NTCIP C2F standards developers into the TPG to see a report of any non-compliance to NTCIP 8002 Annex B1. The report provides any breakages between requirement and design detail.

Using the TPG tool will reduce developmental risks, effort, and the cost of developing standards and test procedures, which in turn will encourage the deployment of interoperable NTCIP C2F systems. Agencies can use the test procedures generated by the TPG to help determine an implementation’s conformance to the NTCIP C2F Device Interface Standards. If extensions to the standard have been added for the project, the test procedures generated by the TPG can be used to help determine compliance to a project specification.

Please note this download for TPGv3 is compatible with Windows 7 or Windows 10 and Microsoft Office 2010 (32 bit) only. The 64 bit version of Microsoft Office has known compatibility issues, for more information please see the user manual.

The ITS C2C RI Tool, Version 3.2, is now available along with the source code and systems engineering documentation on the USDOT ITS JPO Open Source Application Development Portal (OSADP/C2C-RI). This tool supports efficient system deployment using C2C communications by providing a way to verify conformance to C2C standards.

The C2C interface may be between any two centers that need to coordinate regionally or locally regarding corridor or arterial management, incident mitigation, or event management (e.g., two traffic management centers). Specifically, the C2C RI tool supports conformance testing for:

The tool conducts conformance testing of the C2C interface of the system under test (SUT) in two different ways. First, it examines the interface description document to see if it conforms to the two standards mentioned above. Then, the RI tool tests the interface by communicating with the SUT. This communication consists of dialogs between the tool and the SUT. The tool can test a wide range of expected and unexpected (invalid) behaviors since it controls the sequence and contents of the protocol messages sent to the SUT. The tool implements test dialogs based on the users selection of needs and requirements.

The C2C RI tool can reduce developmental risks, effort, and costs. The tool provides consistent interpretations of the implemented standard, which in turn facilitate the deployment of interoperable NTCIP C2C systems.

Version 3.2 of the C2 CRI tool includes the following new features and functional improvements:

  • Speed up entity emulation initialization
  • Changes to Device-id propagates across all data types
  • Additional useful real-time Test Log information
    • More description on errors encountered during conformance testing
    • Show logged messages being transferred without having to exit the tool
  • Provides an option to allow additional verification test steps to continue after one fails.
