Positive Guidance is a high payoff, short-range way to enhance safety of substandard facilities. This report presents three types of information to guide the user in applying Positive Guidance. Part I of this report discusses the principles, concepts and terminology underlying Positive Guidance. Part II presents the procedures for performing the eighteen activites required to accomplish Positive Guidance objectives. Part III presents three case studies to show procedure application and product variation brought on by site differences. The three case studies are urban, signalized intersection; interstate freeway segment; and, a rural two lane road.

Washington State Department of Transportation District #4 conducted a positive guidance demonstration project at milepost 21.77 on Washington State Route 6 in Pacific County. The site was analyzed and improvements made to signage and a berm that blocked the view of the curves and bridge was removed.

The progress that has been made in developing the positive guidance concept is documented, and the meaning of positive guidance, the philosophy of driver performance upon which it is based the nature of the driving task at those locations where positive guidance is applicable, and a procedure for its application are discussed. This report describes what must be done to improve the information system at hazardous locations. Positive guidance which is an information system matched to the facility characteristics and driver attributes, is based on the premise that a driver can be given sufficient information where he needs it and in the form that he can best use to avoid hazards.

Provision of left turn lanes is a major problem which lacks an objective approach. Various techniques and procedures in use have been reviewed. Traffic characteristics at typical Iowa intersections have been measured. A rational approach for inclusion of a left turn lane has been developed, based on relating the benefits to the road user to the cost of providing the added turing lane. An analysis of field data gathered under this project indicates that the use of theoretical distribution to describe vehicle headways is not applicable to rural Iowa two lane roads. As an alternate approach the mass of field data gathered were examined using multiple regression techniques to yield equations for predicting stops and delays. The benefit-cost ratio technique is recommended as the criterion for decision making.

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 305: Interaction Between Roadways and Wildlife Ecology summarizes existing information related to roadway planning, design, construction, operation, and maintenance practices being used successfully and unsuccessfully, nationally and internationally, to accommodate wildlife ecology given the challenging background of rapid growth and diminishing natural resources.
