This Manual is a condensation of a Design Guide report entitled, "Human Factors Requirements for Real-Time Motorist Information Displays, Volume 1 Design Guide," written by the Texas Transportation Institute for FHWA. The Manual provides practical guidelines for the development, design and operation of real-time driver displays, both visual and auditory, for freeway corridor traffic management. The emphasis is on the recommended content of messages to be displayed in various traffic situations; the manner in which messages are to be displayed--format, coding, style, length, load, redundancy, and number of repetitions; and where messages should be placed with respect to the situations they are explaining. The Manual also provides guidance in selection of the appropriate type of display, and guidance in design of the display to improve the target value and reception of the message. Although the Manual is primarily intended for traffic engineers working in city, county, state or private organization, it should also be useful to traffic engineering students or trainees and to FHWA engineers at the district and regional levels who are responsible for project review and approval.
