Enforcement Center --> ITS Roadway Equipment:
automated enforcement parameters
Definitions
automated enforcement parameters (Information Flow): Includes setup information that identifies rules to be enforced, identification of violators, vehicle/user clearance lists, and other information that supports automated enforcement using roadside systems.
Enforcement Center (Source Physical Object): The 'Enforcement Center' represents the systems that receive reports of violations detected by various ITS facilities including individual vehicle emissions, lane violations, toll violations, CVO violations, etc.
ITS Roadway Equipment (Destination Physical Object): 'ITS Roadway Equipment' represents the ITS equipment that is distributed on and along the roadway that monitors and controls traffic and monitors and manages the roadway. This physical object includes traffic detectors, environmental sensors, traffic signals, highway advisory radios, dynamic message signs, CCTV cameras and video image processing systems, grade crossing warning systems, and ramp metering systems. Lane management systems and barrier systems that control access to transportation infrastructure such as roadways, bridges and tunnels are also included. This object also provides environmental monitoring including sensors that measure road conditions, surface weather, and vehicle emissions. Work zone systems including work zone surveillance, traffic control, driver warning, and work crew safety systems are also included.

Interoperability | Description |
---|---|
Local | In cases where an interface is normally encapsulated by a single stakeholder, interoperability is still desirable, but the motive is vendor independence and the efficiencies and choices that an open standards-based interface provides. |

Basis | Should cause no harm if this information were public. | Corruption or manipulation of this flow could cause inaccurate violations, which would be a significant inconvenience (if set to generate more violations that it should). | If this flow cannot function then automated enforcement may in the worst case pause, which has little negative effect on roadway operation. |
