Kentucky’s highway agency has embarked upon an initiative tagged “Practical Solutions” which sets its goal toward reducing costs throughout the project development process extended into operations and maintenance of all highway facilities. This study focuses on the planning and design stages of project development. Developing a procedure that yields up to the maximum margin of return for the investment requires an approach that takes into account specific safety issues and the commensurate design elements for each roadway. Such an approach requires that the project 1) achieves the stated goals/objectives and 2) delivers the highest rate of return for the investment.

The purpose of this study was to examine available research and develop a hypothetical example to establish the efficacy of a practical solutions approach to planning and design as well as to propose a concept and principles for application and provide a real world example of the practical design that could be achieved.
