The California HOV/Express Lane Business Plan is a framework for Caltrans and its partners to focus statewide activity during 2009-2011 that will lead the state to easily implement more flexible and effective system management strategies for HOV and Express Lane, also known as High Occupancy Tolling (HOT) or Managed Lane. The ultimate vision is a transportation system offering new commute choices and more reliable travel through congested corridors; where congestion is managed and the availability of an express service option is greatly improved, and where governments at all levels work together to manage demand with effective monitoring and adjustment of operations and design. In this Business Plan, Caltrans, regional transportation agencies, FHWA and the CHP, have developed a coordinated framework to guide the current and future development and operation of HOV and Express Lane throughout the state, capitalizing on strong partnerships and operating strategies already in place.
