HOV Evaluation and Monitoring Phase IV

This report presents and summarizes the data collected in fulfillment of the requirements for the
Washington State Department of Transportation grant "HOV Lane Evaluation and Monitoring." This
report provides the information necessary to analyze HOV lane performance and development. Data
collection results and analysis are presented, followed by conclusions and recommendations.

The data contained herein were collected during Phase I, Phase II, Phase Ill, and Phase IV of the
high occupancy vehicle lane (HOV) monitoring project (July 1992-June 1998). The data collection
methodology is described in the final report, "HOV Monitoring and Evaluation Tool." Included in this
report are the following primary and secondary measures of HOV lane performance: (1) average vehicle
occupancy data, (2) travel time data, (3) public opinion survey results, (4) transit ridership data, (5)
enforcement, compliance, and adjudication data, and (6) accident data. Data collection issues and their
implications for data availability are discussed.

It is important to note that this report does not evaluate the HOV lane system in the Puget Sound
region. Rather, it is a compilation of the data necessary to conduct a meaningful evaluation. Although
an analysis of public opinion, transit ridership, and enforcement data is provided, the report's primary
purpose is to simply present the data and discuss issues associated with its use -- not to provide an
extensive analysis.
