Physical Object: ITS Roadway Equipment
Roadway Emissions Monitoring
Overview
'Roadway Emissions Monitoring' monitors emissions and general air quality and communicates the collected information back to the Emissions Management Center where it can be monitored, analyzed, and used. This functional object supports point monitoring of individual vehicle emissions as well as general monitoring of standard air quality measures.
This functional object is included in the "ITS Roadway Equipment" physical object.
This functional object is included in the following service packages:
- ST01: Emissions Monitoring
- ST02: Eco-Traffic Signal Timing
- ST03: Eco-Traffic Metering
- ST07: Eco-Lanes Management
- ST10: Low Emissions Zone Management
This functional object is mapped to the following Functional View PSpecs:
Requirements
| # | Requirement |
|---|---|
| 01 | The field element shall include emissions sensors that detect levels of emissions from individual vehicles, under center control. |
| 02 | The field element shall collect vehicle emissions data from passing vehicles. |
| 03 | The 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. |
| 04 | The field element shall 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. |
| 05 | The field element shall provide emissions sensor equipment operational status to the center. |
| 06 | The field element shall provide emissions sensor equipment fault indication to the center for repair. |
| 07 | The field element shall provide area-wide pollution sensor equipment operational status to the center. |
| 08 | The field element shall provide area-wide pollution sensor equipment fault indication to the center for repair. |
| 09 | The field element shall include air quality sensors, often distributed geographically, that detect area-wide levels of pollution, under center control. |
| 10 | The field element shall provide vehicle emission data to centers. |
