Strike-Off Letter 494-25-01: Publication 46, Chapter 12 - Traffic Analysis Software

Strike-Off Letter 494-25-01 was issued on February 25, 2025, updating Chapter 12 of Publication 46 pertaining to traffic analysis software. The only update was replacing Synchro version 11 with Synchro version 12.

Publication 148 Change #2 issued

On January 27, 2025, PennDOT published Change #2 to the December 2011 edition of Publication 148, Traffic Standards-Signals, TC-8800 Series.

The updated Publication 148 is available on PennDOT's website at the following link: https://www.pa.gov/content/dam/copapwp-pagov/en/penndot/documents/public/pubsforms/publications/pub%20148.pdf

Key changes include addressing comments from the CT process for Change #1, clarifying dimension labels for mast arms and strain poles, and adding standardized detection layouts and preemption details. Traffic signal construction and permit plans should reference the standard by sheet number and date rather than duplicating the standard on each plan. Modifications to the standard should continue to be shown on the traffic signal construction and permit plan. A detailed list of changes is included in the Transmittal Letter at the beginning of the document.

These revised Standard Drawings should be adopted on all new and existing designs as soon as possible without affecting any letting schedules and in conjunction with current Publication 408 Specifications. Regardless, revised standards under this release must be used on all projects let after April 11, 2025.

• "ADA" has been added to the title of the Bike/Ped module.
• In the Signal Module, a "Denied" option is added to the Signal Status drop-down.

Bug Fixes

• Resolved the issue of an error when the user downloaded some of the reports in certain modules.
• An error in the Ped/Bike module was fixed when user attempts to edit or delete the street details.

New Module: Roundabouts

• Roundabout records can now be created in TSAMS capturing all the applicable roundabout information.
• The roundabout location can be created from the map as well as entering the latitude and longitude manually.
• User can enter comments and create a comment history for each location like other modules.
• Roundabouts can be associated with one or more projects.

As always, please share your feedback with us at signals@pa.gov. We are especially interested in feedback on the new Roundabout module. Most of the other feature enhancements are directly from user feedback.
