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... More > 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.< Less

Oregon is one of a few states using commercial truck weight-mile tax (WMT). The Oregon Dept. of Transportation (ODOT) developed a system for simpler WMT collection. The Truck Road Use Electronics... More > (TRUE) system includes a smart phone application to collect Global Positioning System (GPS) data. This surpasses other GPS data due to its level of geographic detail and potential to integrate trip origin and destination, vehicle class, and commodity data. This research evaluates the accuracy of TRUE data and demonstrates its use in freight modeling, performance measures, and planning applications. The use of data for highly accurate trip-generation rates and mobility performance measures is demonstrated. TRUE data has strong potential in measuring safety, accessibility and connectivity, system condition and environmental stewardship. The potential for use in emissions estimates including speed profiles and truck type is examined. Integration with weigh-in-motion data will vastly improve emission estimate accuracy.< Less
