Application Areas

Dynamic Message Signs

Description

This area focuses on the critical connection between traffic management centers (TMCs) or maintenance and construction management centers and specific roadway equipment that informs motorists through dynamic message signs (DMS). These signs can be permanently installed or portable and utilize various technologies, including flip panels, multiple lights, and light-emitting diodes. This allows them to display a limited set of messages or fully customized information using various character combinations. A DMS effectively provides real-time updates for motorists, including alerts, advisories, directions for alternate routes, travel times, and work zone notifications.

National ITS Architecture Interface

The interaction between subsystems controlling dynamic message signs and the DMS in the Roadway Subsystem (RS) is essential in this application area. Both the Traffic Management Subsystem (TMS) and the Maintenance and Construction Management Subsystem (MCMS) communicate with the DMS to manage its functionality through the exchange of information necessary for initialization, configuration, and control. This data transfer includes the specific messages to be displayed and details such as font choices, character sets, maintenance requests for local message storage, control mode instructions, and inquiries regarding the equipment's status and condition. In response, the DMS provides current operational status, including any fault information, upon request.

Applicable Standards

This application area encompasses the linkage between traffic management structures and roadway equipment, specifically targeting the dynamic message signs (DMS). Utilizing various technologies, these signs can either be fixed or mobile and are capable of conveying a range of messages, thus serving a crucial informational role for motorists. The framework includes requisite interfaces that enable subsystems like TMS and MCMS to send various commands and messages to the DMS, ensuring its proper functioning. These commands include requests for message displays, font settings, and other operational parameters, with the DMS answering with its current status and any detected faults.

Generally, specific standards apply to the implementation of Dynamic Message Signs. Identifying the right standards requires an assessment of which architectural flows are necessary for your DMS-related deployment. It is advisable to consult with your local FHWA ITS Division Specialist or an ITS Standards Program Field Support Team member for assistance.

Numerous dynamic message signs have been deployed across District Six, enabling traffic managers at the SunGuide® Transportation Management Center (TMC) to relay real-time traffic conditions and notify drivers of impending delays. The TMC staff collaborates with partner agencies to formulate comprehensive message strategies that keep motorists updated about lane blockages, travel times, construction schedules, safety information, and special events.

 

The SunGuide TMC is dedicated to effectively managing and operating this service to facilitate better traffic conditions and ensure drivers reach their destinations more safely and efficiently.
