Samenvatting
A study of medians was conducted in Kentucky based on accident experience to provide a means for determining the optimum median design form the standpoint of safety. Findings indicate: 1) a definite relation between the width of the median and accident rate 2) the deeply depressed median types have a disproportionately severe accident record and 3) separate roadway sections of interstate highways have a much worse accident record than typical sections of the same roads.
