Abstract
The complex problem of informing, guiding, and warning the motorist on today's crowded streets and highways is discussed. The major difficulties with current traffic signs are identified. Symbols, either pictographs or abstract designs, are pointed out as perhaps the most widespread example of confusing traffic sign information. It is suggested that near accidents rather than accidents be examined to evaluate traffic signs. The meaning of traffic signs has been shown to be unknown to a large proportion of drivers.
