The objective of the research was to determine the effectiveness of various alternative strategies for reallocating the usage of street width on urban arterials without changing the total curb-to-curb width. The Design alternatives that were evaluated ranged from a two-lane undivided cross-section to cross-sections with as many as eight lanes for through traffic. Evaluations were performed of the safety effectiveness of 35 improvement projects that involved use of lane widths of 10 ft or less. Field observations of passenger car and truck operations on selected sites were also conducted. The report includes a recommended process for selecting appropriate improvement strategies for urban arterials based on their traffic operational and safety effects. Guidelines for implementation and evaluation of projects are presented.
