Abstract

A symposium was conducted as a form of collective research for examination of resultant operation data on the design of narrow medians. Through the cooperation of seven state highway departments, reports were obtained with information on 23 different narrow median designs for 5 general highway conditions. Narrow medians were considered to be those 8 feet or less in width, of raised curb, rounded or flush sections. The general conditions were: (1) rural divided highways, without control of access, (2) major streets through residential or suburban areas, (3) major streets through business areas or with ribbon commercial development, (4) long structures or elevated highways, and (5) expressways. A tabulation is presented which is a summary of these reports.
