N2  - Highlights of a technical investigation conducted to evaluate various designs of HOV lanes currently in use on freeways in California are presented. Operational efficiency and safety were the measures of effectiveness examined. None of the currently operating facilities was found to contain severe operational or accident problems. All three of the broad design types identified in the state and studied were found to be operating relatively smoothly. Although statistically reliable conclusions could not be made, it did appear that certain designs were better than others. The physically separated facility appears to be the safest type because interaction of HOV lane vehicles and mixed flow vehicles is virtually eliminated. Of the facilitis that were physically separated (which were the primary focus of the study), the wide buffer (full lane width) facility was clearly superior to the contiguous types. The study was unable to differentiate between the various continuous designs, which were categorized by whether they restrict intermediate access or not.
