The substance of the conference is divided into four parts: 1. A speech surveying the total problem. Information sources are divided into four categories: the motorist's own car, other cars, the road environment, all others. Information itself is categorized in several ways, such as natural vs. artificial, continuous vs. intermittent, changing vs. static, visual vs. auditory, positive vs. negative. Both excessive and insufficient density of information as well as the lack of credibility of some roadside signs are mentioned as deterrents to ideal communication. 2. Two speeches on information that comes from the road environment. Points discussed are the problem of excessive concentrations of signs, international conventions of signs, the trend toward using pictures instead of words on signs, and the use of information from the road area in making predictions. In the ensuing discussion, the importance of having an orderly array of signs, avoiding incorrect information and allowing enough time for interpretation of signs, as well as the possibility of using auditory and sensory sources of information were mentioned. 3. Two speeches on information transfer between motorists. The need for international standardization of lights on cars and having lights, mirrors and windows in good condition is discussed. Information is viewed as a tool for making predictions, and motorist behavior is analyzed schematically. Three possibilities for action are action are suggested: diminishing the amount of information the driver must handle, improving information transfer, and increasing motorists' and increasing motorists' capacity for processing information. 4. A concluding discussion. Excessive comfort in cars is viewed as a danger as it separates the driver from the environment. The possibilities of informing drivers of the dangers they are not experiencing, the testing a driver's awakeness before he drives are viewed as potential ways of increasing drivers' attention to signs.
