High Occupancy Vehicle

High-Occupancy Vehicle (HOV) lane, also known as the carpool or diamond lane, is a traffic management strategy to promote and encourage ridesharing; thereby alleviating congestion and maximizing the people-carrying capacity of California highways. HOV lane is usually located on the inside (left) lane and is identified by signs along the freeway and white diamond symbols painted on the pavement. In Northern California, HOV lanes are only operational on Monday thru Friday during posted peak congestion hours, for example: between 6 a.m. - 10 a.m. and 3 p.m. - 7 p.m. All other vehicles may use the lanes during off-peak hours. This is referred to as "part-time" operation. In Southern California, HOV lanes are generally separated from other lanes by a buffer zone. The HOV lanes are in effect 24-hours a day, 7-days a week, referred to as "full-time" operation. The locations of the HOV system are based on postmiles derived from an excel spreadsheet maintained by Caltrans, Division of Traffic Operations, Office of Traffic Management. High-Occupancy Vehicle Systems Page高载客量车辆（High-Occupancy Vehicle，简称HOV）车道，俗称拼车车道或菱形车道，是一项旨在推广与鼓励合乘出行的交通管理策略，以缓解交通拥堵、最大化提升加利福尼亚州高速公路的载客通行能力。HOV车道通常设置在内侧（左侧）车道，通过沿线高速公路的标识牌以及路面施划的白色菱形标志进行识别。在加利福尼亚州北部，HOV车道仅在周一至周五的规定高峰拥堵时段启用，例如早6时至10时、晚3时至7时；其余非高峰时段，其他车辆可使用该车道，此种运营模式被称为“部分时段运营”。在加利福尼亚州南部，HOV车道通常通过缓冲区与其他车道分隔，且采用“全时段运营”模式，即每周7天、每天24小时均生效。HOV车道系统的点位信息源自加州交通局（Caltrans）交通运营部交通管理办公室维护的Excel电子表格所导出的里程桩号数据。高载客量车辆车道系统页面
