The operation of a vehicle is a complex process for the driver. To ease the task and to improve operations and safety, it is necessary to incorporate communicative aspects in highway design, i.e., to make clear to the driver the messages conveyed by the facility. Numerous geometric and control features that have been formulated in response to human-factors inputs are presented in this paper. Particular attention is directed to various features of design. Among these are alignment, sight distance and cross-sectional features, and operational uniformity, route continuity, and marking and signing. The suggested guidelines permit immediate application and are a starting point for improving design criteria on a larger scale. They could significantly improve the operational efficiency and safety on both existing and new facilities, but the designer's input--his or her philosophy and skill--must play an important role in meeting the objective of achieving optimum design. /Author/
