An unformatted version of the full report will be available for review by request by sending an email to TSCI-RP@ite.org.  Please select the link above to see the full Notice of Intent to Adopt on the ITE website.

Summary

The final version of Guidelines for Determining Traffic Signal Change and Clearance Intervals (RP-040A) is moving for final adoption by the Institute of Transportation Engineers (ITE) International Board of Direction. ITE has made the recommended practice available on May 8, 2019 for review and will submit the recommended practice for adoption as of June 10, 2019 if no appeals are received. In response to the comments received on the initial proposed version of the document, the report has been revised to:

  • Modify the approach for rounding values of approach speeds;
  • Modify discussion and guidance related to enforcement tolerances;
  • Supplemented discussion and guidance related to intersection width;
  • Expand discussion of application for turning movements;
  • Supplemented text and formula references in the guidance that the calculation of the yellow interval is minimum value;
  • Clarify aspects of intersection width;
  • Modify discussion and requirement for the use of non-zero conflicting movement start-up delay; and
  • Include other technical and editorial revisions to improve readability and clarity of the report.

How to File an Appeal

If you wish to appeal ITE’s adoption of the recommended practice, submit a written appeal to ITE Headquarters, Attn: Douglas E. Noble, 1627 Eye Street, NW, Suite 600, Washington, DC 20006 USA, by the close of business on June 10, 2018.

Any previous efforts to resolve the objection(s) and the outcome of each shall also be noted.
