Traffic Management Center --> Multimodal Crossing Equipment:
multimodal crossing inhibit
Definitions
multimodal crossing inhibit (Information Flow): It contains commands that will inhibit the operation of a multi-modal crossing so that it will not stop or restrict the normal flow of road traffic.
Traffic Management Center (Source Physical Object): The 'Traffic Management Center' monitors and controls traffic and the road network. It represents centers that manage a broad range of transportation facilities including freeway systems, rural and suburban highway systems, and urban and suburban traffic control systems. It communicates with ITS Roadway Equipment and Connected Vehicle Roadside Equipment (RSE) to monitor and manage traffic flow and monitor the condition of the roadway, surrounding environmental conditions, and field equipment status. It manages traffic and transportation resources to support allied agencies in responding to, and recovering from, incidents ranging from minor traffic incidents through major disasters.
Multimodal Crossing Equipment (Destination Physical Object): 'Multimodal Crossing Equipment' represents the control equipment that interfaces to a non-road based transportation system at an interference crossing with the roadway. The majority of these crossings are railroad grade crossings that are more specifically addressed by the "Wayside Equipment" terminator. This multimodal crossing terminator addresses similar interface requirements, but for other specialized intersections like draw bridges at rivers and canals. These crossings carry traffic that may take priority over the road traffic at the intersection. The data provided will in its basic form be a simple "stop road traffic" indication. However more complex data flows may be provided that give the time at which right-of-way will be required and the duration of that right-of-way requirement.

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 | There should be no sensitive information in this flow. Raise to MODERATE if reverse engineering of a proprietary interface is a concern. | This information can indicate when a road is closed to due a drawbridge being raised, which has a significant effect on traffic. If this information were falsified, it could have a significant negative effect on mobility over a large area. | Should not require rapid response or frequent update. Raise to MODERATE if frequent real-time updates are part of the system scope. |
