Research Highlights

Exploiting a Next Generation ITS Data Warehouse for Improved System Performance and Congestion Monitoring

Kristin Tufte
David Maier
The objective of this project is to build on an existing data archive platform, known as the Portland Oregon Regional Transportation Archive Listing (PORTAL) toward development of next generation performance measurement and congestion reduction tools (1,2,3,4). Established in 2004, PORTAL currently includes data recorded by approximately 600 freeway sensors in two states, plus hourly weather data, incident data, and variable message sign data. This project will advance PORTAL's capabilities i... Read More

Multimodal Data at Signalized Intersections: Strategies for Archiving Existing and New Data Streams to Support Operations and Planning

Christopher Monsere
Kristin Tufte
The Portland (OR)-Vancouver (WA) metropolitan region's officially designated archived data user service PORTAL - the Portland Oregon Regional Transportation Archive Listing - has undergone the transition from a pure research project to a regional resource. At present, however, PORTAL primarily contains vehicle observations on freeways. The freeway coverage is robust and detailed: traffic observations of speed and count every 20 seconds from 671 loop detectors (at about 100 stations) and detai... Read More
