Functional Requirements

IDRequirement
01The field element shall include emissions sensors that detect levels of emissions from individual vehicles, under center control.
02The field element shall collect vehicle emissions data from passing vehicles.
03The field element shall analyze collected vehicle emissions data against reference data to determine whether or not a vehicle is violating the acceptable levels of emissions, and shall return this analysis to a center for possible enforcement action.
04The field element shall be able to display summary emissions information or warnings to passing drivers via a driver information system (such as portable messages signs, field to vehicle communications to in–vehicle signing systems, etc.), if the emissions level detected by the emissions sensor indicates a vehicle is violating the acceptable levels of emissions.
05The field element shall provide emissions sensor equipment operational status to the center.
06The field element shall provide emissions sensor equipment fault indication to the center for repair.
07The field element shall provide area–wide pollution sensor equipment operational status to the center.
08The field element shall provide area–wide pollution sensor equipment fault indication to the center for repair.
09The field element shall include air quality sensors, often distributed geographically, that detect area–wide levels of pollution, under center control.
10The field element shall provide vehicle emission data to centers.
