Measuring of Recurring and Non-Recurring Congestion: Phase IIB
The focus of this project is on the extension of the Washington State Department of Transportation (WSDOT) Phase I freeway congestion delay estimation methodology to account for different categories of non-recurring events and corridor attributes, and the production of specific analytical results using the enhanced methodology and real-world data. The Proposed project (Phases IIA and IIB combined) has the following objectives: (1) Enhance the Phase I congestion delay methodology by refining the key threshold parameter, and adding additional capabilities to allocate the estimated non-recurring portion of congestion delay to specific cause in additional to lane-blocking incidents. (2) Enhance the Phase I methodology to analyze potential relationships between congestion patterns and corridor attributes, and explore the feasibility of developing general observation that can be used in other urban areas. (3) Prepare detailed analytical results using these methodology extensions and Seattle area freeway data. (4) Prepare cleaned and filtered data sets of traffic, incident, and other related data, for use by other mobility monitoring research efforts.
