Driver Information Requirements and Acceptance Criteria. Paper presented at the 48th Annual Meeting of Highway Research Board HRB, Washington, D.C., 1969.

The purpose of this study was to analyze the route guidance information required and preferred by drivers. Required driver information was derived by determining how an unfamiliar driver negotiated a generic intersection. The generic intersection was defined in terms of (a) choice point (b) characteristics of the approach to the choice point, and (c) characteristics of exit paths.
