Maint and Constr Management Center --> Media:
road weather information

Definitions

road weather information (Information Flow): Road conditions and weather information that are made available by road maintenance operations to other transportation system operators.

Maint and Constr Management Center (Source Physical Object): The 'Maint and Constr Management Center' monitors and manages roadway infrastructure construction and maintenance activities. Representing both public agencies and private contractors that provide these functions, this physical object manages fleets of maintenance, construction, or special service vehicles (e.g., snow and ice control equipment). The physical object receives a wide range of status information from these vehicles and performs vehicle dispatch, routing, and resource management for the vehicle fleets and associated equipment. The physical object participates in incident response by deploying maintenance and construction resources to an incident scene, in coordination with other center physical objects. The physical object manages equipment at the roadside, including environmental sensors and automated systems that monitor and mitigate adverse road and surface weather conditions. It manages the repair and maintenance of both non-ITS and ITS equipment including the traffic controllers, detectors, dynamic message signs, signals, and other equipment associated with the roadway infrastructure. Weather information is collected and fused with other data sources and used to support advanced decision support systems.

The physical object remotely monitors and manages ITS capabilities in work zones, gathering, storing, and disseminating work zone information to other systems. It manages traffic in the vicinity of the work zone and advises drivers of work zone status (either directly at the roadside or through an interface with the Transportation Information Center or Traffic Management Center physical objects.)

Construction and maintenance activities are tracked and coordinated with other systems, improving the quality and accuracy of information available regarding closures and other roadway construction and maintenance activities.

Media (Destination Physical Object): 'Media' represents the information systems that provide traffic reports, travel conditions, and other transportation-related news services to the traveling public through radio, TV, and other media. Traffic and travel advisory information that are collected by ITS are provided to this object. It is also a source for traffic flow information, incident and special event information, and other events that may have implications for the transportation system.

Communication Solutions

Solutions are sorted in ascending Gap Severity order. The Gap Severity is the parenthetical number at the end of the solution.

Selected Solution

US: TMDD - NTCIP Messaging

Solution Description

This solution is used within the U.S.. It combines standards associated with US: TMDD with those for C-C: NTCIP Messaging. The US: TMDD standards include upper-layer standards required to implement center-to-center communications with traffic management systems. The C-C: NTCIP Messaging standards include lower-layer standards that support partially secure communications between two centers as commonly used in the US.

Note that some layers might have alternatives, in which case all of the gap icons associated with every alternative may be shown on the diagram, but the solution severity calculations (and resulting ordering of solutions) includes only the issues associated with the default (i.e., best, least severe) alternative.

Interoperability Description
Regional Interoperability throughout the geopolitical region is highly desirable, but if implemented differently in different transportation management jurisdictions, significant benefits will still accrue in each jurisdiction. Regardless, this Information Flow Triple should be implemented consistently within a transportation jurisdiction (i.e., the scope of a regional architecture).

Basis Used to feed other processes that produce data for public distribution and center-based decision making processes. Widely distributed, no need for obfuscation. There are lots of ways to corroborate and receive this data. While travelers and operators make decisions based on this, if it is not available or incorrect the largest impact is probably confusion.
