ITS Roadway Equipment --> Traffic Management Center:
barrier system status

Definitions

barrier system status (Information Flow): Current operating status of barrier systems. Barrier systems represent gates, barriers and other automated or remotely controlled systems used to manage entry to roadways. Status of the systems includes operating condition and current operational state.

ITS Roadway Equipment (Source 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.

Traffic Management Center (Destination 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.

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

(None-Data) - OASIS AMQP

Solution Description

This solution is used within Canada, the E.U. and the U.S.. It combines standards associated with (None-Data) with those for OASIS AMQP. The (None-Data) standards include an unspecified set of standards at the upper layers. The OASIS AMQP standards include lower-layer standards that support data distribution of specific types of data.

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.

Rating Moderate High Moderate
Basis Related to the control flow, however the data is directly observable and generally widely known. Difficult to justify obfuscation. Status of barrier systems has direct human-safety related impact, that if performed incorrectly could lead to catastrophic incidents. These systems need to operated when demanded or mobility will be restricted. However, manual processes should always be in place to compensate for a loss in connectivity, and to provide a secondary check for safety purposes anyway.
