The Mineta Transportation Institute) at San José State University conducted this study to review the issues and implications involved in the project in question. Twenty-four potential HOV facility user groups were identified. Through a ranking process, seven of these groups were selected for further study in phase one. The project team made the following preliminary conclusions as to the suitability of each group to use HOV facilities and recommended whether each group should be included in the phase two study to refine these findings and develop implementation strategies. 1. As the result of 1998 legislation, which includes sunset provisions, electric vehicles and other ILEVs, ULEVs, and SULEVs have recently been included in users of HOV facilities. This legislation should be reviewed in phase two to determine if the sunset provisions should be extended. 2. The identified negatives for including light delivery trucks outweigh any identified positives. Unless new evidence surfaces, this group should be dropped from the study. 3. Radio dispatched vehicles are strong candidates, inclusion should result in improved public transportation services. Phase two study of possible enabling legislation should consider sunset provisions to encourage future fleet conversion to vehicles using alternative fuels. 4. Inclusion of EPA certified high mileage vehicles and vehicles using alternative fuels could encourage use of these vehicles with beneficial impacts on air quality and fuel consumption. Possible significant problems of capacity, identification of users, and police monitoring and enforcement should be studied in phase two. 5. Deadheading transit and charter buses appear to be worthy candidates and should be studied further. School buses, because of inherent problems, should not be considered unless significant warrants surface. 6. There does not appear to be any advantage in including light service trucks (utility, maintenance, etc.). 7. There is no compelling reason to change existing conditions regarding enforcement and emergency vehicles.
