PORTAL provides a centralized, electronic database that facilitates the collection, archiving, and sharing of data and information for public agencies within the region. The data stored in PORTAL includes 20-second granularity loop detector data from freeways in the Portland-Vancouver metropolitan region, arterial signal data, travel time data, weather data, incident data, VAS/VMS message data, truck volumes, transit data, and arterial signal data. Many of these data feeds are received by PORTAL in real time or on a daily basis and for most, the retrieval and archiving process is fully automated.

BikePed Portal: Jurisdictions around the country are collecting non-motorized traffic count data, but the lack of a centralized database inhibits data sharing and greatly reduces the utility of this important and growing dataset. In response, we created a national online non-motorized traffic count archive. This archive allows users to upload, view and download data. Access to a centralized non-motorized traffic data archive opens the door to innovation in research, design, and planning.
