Summary

HOV lanes have remained a controversial issue since 1970 in Santa Monica and, with recent widespread implementation, across California. This project seeks to provide factual evidence regarding the effectiveness of existing HOV lanes through field-testing. Methodologies for predicting the HOV lane effectiveness on the basis of air quality and freeway performance will be created from field data.

There are six major tasks involved in the project: 1) a comprehensive literature review, followed by the synthesis of current knowledge, 2) the assembly and analysis of current and historical field data, 3) the assessment and development of methodologies for estimating air quality, 4) the application of a modified FREQ model, 5) the application of off-line modified PeMS database, and 6) the documentation and presentation of HOV lane effectiveness.
