Highway Advisory Radio (HAR) provides traffic operating agencies with the capability to communicate traffic and travel related information to motorists using the vehicle's AM radio receiver. This report presents recommended HAR message development principles. Included are a set of programming principles for constructing messages and examples of messages which apply the principles to specific situations. The examples include: construction zones, lane blockages, route diversions, special events including parking control, inclement weather advisories, and tourist information. Specifically, guidelines are provided for message content, format, length, load, and delivery style. The guidelines are based on a research program which included a survey of the techniques currently employed by operational HAR systems. The report also emphasizes message construction procedures and the common pitfalls to be avoided.
