Requirements

# Requirement
01 The field element shall include sensors to detect high-occupancy vehicle (HOV) lane usage, under center control.
02 The field element shall include driver information systems to notify users of lane status for lanes that become HOV or High Occupancy Toll (HOT) lanes during certain times of the day on freeways, under center control.
03 The field element shall include freeway control devices, such as ramp signals and mainline metering and other systems associated with freeway operations that control use of HOV lanes, under center control.
04 The field element shall collect a count of vehicle occupants from passing vehicles using field-vehicle communications.
05 The field element shall provide traffic flow measures and information regarding vehicle occupancy (i.e., lane usage) in HOV lanes to the center.
06 The field element shall return operational status for the HOV lane sensors to the controlling center.
07 The field element shall return fault data for the HOV lane sensors to the center for repair.
