Kentucky Median Type
GuidanceThe purpose of this technical
white paper is to provide a summary of the proposed median type standards for
incorporation in the Kentucky Highway Access Management Plan. The proposed
standards are based on independent engineering analysis and previous research
conducted on median type applications. The results of these studies are
presented below.

HandbookThe purpose of this document is to
guide the professional through the existing rules, standards and procedures, as
well as to provide current national guidance on the best ways to plan for
medians and median openings. Unless stated otherwise or specifically referenced,
this is not a set of standards or a Departmental Procedure but is a

LocationsThis study evaluated the impacts of
the offset distance between driveway exits and downstream median opening or
signalized intersection on the safety and operational performance of vehicles
making right-turns followed by U-turns. This study evaluated the impacts of
offset distance under 4 different roadway conditions including...

U-Turns at Unsignalized Median OpeningsMany
state and local transportation agencies are considering installing
nontraversable medians on multilane arterial highways to improve safety and
travel times. Business and property owners often resist such improvements
because they and their customers may be denied the opportunity for direct
left-turn access to or from their property.

Median Intersection Design
for Rural High-Speed Divided Highways
The purpose of
this study was to explore common safety issues, discuss alternative safety
improvements at rural intersections and to report experiential data collected
from agencies who have tried alternative methods. The report contains 10 case
studies showing how different alternatives have been used in the field.
