Exploiting New Data Sources to Quantify Arterial Congestion and Performance Measures at a Regional Scale By Miguel Figliozzi

Travel time and operating speed influence transit service attractiveness, operating cost and system efficiency. As part of their bus dispatch system (BDS), the Tri-County Metropolitan Transportation... More > District of Oregon (TriMet) has been archiving automatic vehicle location (AVL) and automatic passenger count (APC) data for all bus trips at the stop level since 1997. In 2014, a new and higher-resolution bus AVL data collection system was fully implemented. The new AVL system provides stop-level data as well as five-second resolution (5-SR) bus position data between stops. This research project explored potential applications of the new data for assessing transit performance and for estimating transportation system performance measures for urban streets and arterials. Results suggest that the 5-SR data provides high-resolution time and position information which can be used to determine bus travel speeds between bus stops, identify speed breakdowns, and estimate intersection signal/queuing delays.< Less

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
