This research report describes our efforts to assemble and develop a multimodal archive for the Portland-Vancouver region. The preliminary nature of the archiving process means that some of the data are incomplete and samples. The arterial data sources available in the Portland-Vancouver region include data for local agencies (City of Portland, Clark County, WA, TriMet and C-TRAN) covering vehicle, transit, pedestrian, and bicycle modes. We provide descriptions of each data source and a spatial and temporal classification. The report describes the process for extracting data from the agency systems and transferring these data to our multimodal database. A number of novel visualizations were created. These are summarized in this report and examples are shown. Efforts to monitor data quality and automate data quality processing are explored. Finally, the report presents efforts to combine transit and travel time data and signal timing and vehicle count data to generate some sample congestion measures.
