The Approach
To deliver an improved system with limited resources, KYTC must find ways to extract more value from our expenditures.
KYTC will derive this value from “Practical Solutions.”

TECHNICAL DEFINITIONprac-ti-cal so-lu-tions (prăk´tĭ-kəl sə lóosh'ns) n.
3. An approach to transportation in which an improvement is considered on the basis of its contribution to the entire system instead of its individual perfection.

THE GROUND RULES:
“Practical Solutions” is NOT:Cutting Corners
We must deliver the system as promised.
Compromising SafetyEvery project gets safer.
A Magic BulletIt will not solve all our problems.
![Page 21: PRACTICAL SOLUTIONS Good roads creating a great system](https://reader035.vdocument.in/reader035/viewer/2022070414/5697c0141a28abf838cccffd/html5/thumbnails/21.jpg)
Guiding Concepts
Meet goals of purpose and need. Improve safety over existing conditions. Design to meet anticipated capacity
needs. Consider all possible options and
alternatives. Target minimum design values. Design and justify all elements.
![Page 22: PRACTICAL SOLUTIONS Good roads creating a great system](https://reader035.vdocument.in/reader035/viewer/2022070414/5697c0141a28abf838cccffd/html5/thumbnails/22.jpg)
Summary
More projects with same funds Decreased traffic delays Improved safety
Potential for setting system-wide approach and priorities
Appropriate and contextual design
