The amount of available transportation data is always increasing. Learn some ways to turn that data into actionable information for traffic signal systems.

Decision-Making Based on Automated Traffic Signal Performance Measures
Automated Traffic Signal Performance Measures (ATSPMs) allow an agency to apply a performance-based approach to their signal system. Many agencies currently retime their traffic signals based on a set schedule or in response to public service requests. These methods may not lead to the most-critical locations being retimed, and staff must often spend large amounts of time diagnosing problems. Introducing ATSPMs can help an agency make decisions about their traffic signal systems – when to retime signals, which corridors to review, and which equipment to replace.

This presentation will give an overview of the most common performance measures and how they can be used to make decisions, using the City of Portland’s deployment of the Utah Department of Transportation (UDOT) system as an example. It will also include information on equipment requirements, software options, and lessons learned at deployments across the country.

Put a Datum on It: Integrating Traffic Signal Systems and Big Data in Portland, OR
This presentation introduces three use cases for transportation-related data collection and analysis in the Portland, OR region: air quality, corridor performance, and rail activity. The city has been increasing its collection and analysis of a variety of data sources to better answer questions about citizen travel and safety. The value of each data source is demonstrated through integration with the traffic signal system network, opening the possibility of enhanced performance measures.
