Portal Data Archive

As part of the VAST Program, RTC and the VAST agencies have established an ongoing partnership with Portland State University and Portland area transportation agencies to maintain and improve the data archive hosted by the ITS Lab at PSU known as Portal. The archive contains, in a single location, historical and real-time transportation data from agencies in the Vancouver-Portland region. This one-stop information warehouse can be used by researchers, planners, traffic engineers, and the public to look at multimodal transportation performance throughout the region.

For 2014, RTC is working with Portal staff to implement several enhancements to the archive site, including infill of missing WSDOT data and the addition new Clark County detection data. The VAST partners will maintain their close collaboration for continued improvements to the data archive.

The maps below compare live traffic speeds with average traffic speeds over the last 5 weekdays for the current 15 minute time period.

The full data archive site contains detailed information on vehicle miles traveled, speed, and travel time for freeway corridors and individual locations along a freeway. The site also includes sample arterial and transit data for download. The Portal team is currently working to build a comprehensive set of arterial and transit information from the Vancouver/Portland bi-state region for inclusion in the data archive.
