Determining Surface Street LOS Using Existing Detector Infrastructure: Monitoring Commuter Congestion on Surface Streets in the Salt Lake Valley

摘要

The purpose of this research is to develop an algorithm that enables Traffic Operation Center (TOC) operators to monitor commuter congestion along the surface street arterials. This research requires using the existing hardware or hardware which is planned to be used in the Salt Lake Valley. The goal of this research is to determine if the TOC can monitor surface street commuter congestion using existing data collection from available field devices. Some devices have constraints placed on the data collection, i.e., flow in five-minute intervals, occupancy in five-minute intervals, and signal timing (green time and cycle length) in one-second intervals.
