SPATIALLY REFERENCED PROBE DATA PERFORMANCE MEASURES FOR INFRASTRUCTURE INVESTMENT DECISION MAKERS

摘要

The recent highway bill, “Moving Ahead for Progress in the 21st Century (MAP-21)” challenges our profession to develop a comprehensive set of performance measures for managing most aspects of our transportation system. Historically, performance metrics have been created on an agency by agency basis, with very little consistency between data collection frequency and quality. In recent years, crowd sourced data have developed into a high-fidelity data source, which could be used to develop spatially oriented performance measures that can scale nationwide. This paper summarizes the rapidly evolving probe vehicle data literature and proposes a series of performance measures to characterize the temporal and spatial aspects of congestion in a graphical manner that decision makers may use to evaluate the impact of past investments and prioritize future investments. The methodologies are presented using the I-80/94 corridor in Northwest Indiana, adjacent to Chicago. The paper concludes by discussing how these techniques can be extended on a national scale to characterize corridors such as I-80 from New York to California.
