This report documents an operational analysis of I-405 HOV facilities. The primary objectives of this analysis were (1) to provide information that could assist in the development of a coordinated plan for the I-405 high-occupancy vehicle (HOV) lane system to ensure that the existing and planned HOV facilities worked together and that transitions between facilities occurred smoothly, and (2) to survey the I-405 commuters as a means of understanding their perceptions of HOV lane operations and constraints on the ability of single-occupant vehicle (SOV) commuters to rideshare.
The analysis included an overview of HOV lane operations in the United States, a public opinion survey of commuters who primarily lived and worked east of Lake Washington, results of focus groups with workers who lived in east King County, transportation modeling centering on the I-5 corridor, traffic analysis of HOV lane options, a cost effectiveness analysis, and the results of a symposium that presented and discussed the results of the project.
