Understanding the relative magnitude of recurrent versus non-recurrent congestion is critical to the selection of appropriate countermeasures and proper allocation of resources for congestion alleviation. However, small to medium sized cities typically lack the extensive traffic sensor networks necessary to monitor and record traffic performance on a regular basis. Thus alternative data collection methods are needed in such settings to allow for the study of recurrent and non-recurrent congestion patterns. The objective of this paper is to investigate the potential use of Global Positioning System (GPS) probe vehicle data to identify and measure non-recurrent congestion.
