AUDITORY MESSAGE STUDIES FOR ROUTE DIVERSION
Four studies on auditory messages to motorists are reported. The results in Studies 1 and 2 indicate that drivers can handle up to four units of route information successfully. When the messages contain more than four units of information, drivers make unacceptably large numbers of errors when attempting to follow a route. Study 3 showed that drivers could choose and retain general information from auditory messages in which they had an interest and that the difficulty of the message was increased as exit and route numbers were increased. Study 4 developed information on the lead distances that visual signs alerting motorists of the availability of auditory information need to be placed from the broadcast areas.
