T3 Webinars are brought to you by the Intelligent Transportation Systems (ITS) Professional Capacity Building Program of the U.S. Department of Transportation's (U. S. DOT) ITS Joint Program Office (JPO).

Background

Dynamic message signs (DMS) have been used by transportation agencies to provide traffic information to drivers. Over the years, they have become key elements of many transportation management systems and advanced traveler information systems. DMS deliver traffic condition information to motorists regarding incidents, expected delays, travel times, diversion routes, and lane closures, etc. Many transportation agencies also display non-traffic related messages on DMS.

To be effective, a DMS must communicate useful messages that can be read and comprehended by drivers. This webinar will discuss how to present DMS messages effectively that could be easily comprehended by drivers. The discussion will include the effectiveness and safety of traffic and non-traffic related messages displayed on DMS. The webinar will also discuss how graphic-aid messages help the drivers better understand the messages and how New Jersey Turnpike Authority (NJTA) uses full color/full matrix DMS to enhance its traveler information program.

Agenda

Dr. Kathleen Harder will provide an overview of her research on designing “cognitively digestible” content on changeable message signs. She will share how effective information design influences drivers' understanding and behavior.

Dr. Jay Wang will share his research findings about message display on DMS. He will talk about issues in the design and display of DMS messages, the effects of adding graphics to the signs, and the results obtained from comparing motorists responses to both conventional and graphic-aided DMS.

Henry (Chip) Eibel Jr. and John Biront will focus on the design and operation of DMS boards, as well as the lessons learned over the past two years. The New Jersey Turnpike Authority (NJTA) is in the process of installing over 200 Full Matrix Color DMS units on the Garden State Parkway and the New Jersey Turnpike.
