Automated Traffic Signal Performance Measures

Automated Traffic Signal Performance Measures Workshops

From June 2017 to March 2019, the Federal Highway Administration (FHWA) traveled the nation delivering peer-exchange workshops to champion the use of automated traffic signal performance measures (ATSPM) strategies, along with objectives- and performance-based approaches to traffic signal program management. The purpose of the workshops was to provide a catalyst for States and regions to advance to the next stage of ATSPM implementation, described as national goals in the Everyday Counts round 4 (EDC-4) ATSPM Implementation Plan. While the workshops were customized to the needs of each specific state or region, workshops generally featured the following content:

• Overview of objectives- and performance-based approaches to traffic signal program management. In order to set the stage, an FHWA representative presented an overview of objectives- and performance-based traffic signal program management. ATSPM is most beneficial when used as a tool to support objectives- and performance-based traffic signal timing. Speakers discussed how ATSPM can be used to determine if traffic signal timing objectives are being achieved and how ATSPM can suggest strategies and tactics to further improve system performance.
• Overview of the development of ATSPM. Typically facilitated by Dr. Chris Day from Iowa State University, this section introduced the history of ATSPM, the motivations behind its development, required system components, and use case examples. Dr. Day played a fundamental role in the development of ATSPM during his time at Purdue University. Focus was paid primarily to the ATSPM Open Source Software, currently maintained by the Utah Department of Transportation.
• Peer experience. In this workshop section, peer agencies were invited to present their experience using ATSPM to improve their traffic signal management programs. In order to offer a balanced perspective, the peers invited were often a mixture of out-of-state agencies with mature programs and local agencies that were early ATSPM adopters.
• Implementation alternatives. With the recognition that the open-source ATSPM software is not the only ATSPM architecture, some workshops included a portion dedicated to ATSPM software implementation alternatives. This normally included several vendor presentations featuring examples of embedded ATSPM solutions or cloud-based ATSPM solutions.
• Challenge for action. At the conclusion of the workshops, the audience was challenged to consider any barriers to ATSPM implementation that must be overcome and to identify concrete short-term and long-term steps they could take to advance implementation of ATSPM in their agency.

Between June 2017 and March 2019, 17 workshops were held in 17 cities in 15 states, reaching over 750 total participants.
