INDEPENDENT VERSUS NARROW-MEDIAN ALIGNMENT: COMPARATIVE ECONOMY, SAFETY, AND AESTHETICS

INDEPENDENT ALIGNMENTS AND OTHER WIDE-MEDIAN DESIGNS ARE GENERALLY SUPERIOR TO NARROW-MEDIAN DESIGNS FROM THE STANDPOINT OF SAFETY AND AESTHETICS. FOR A WIDE RANGE OF DESIGN AND COST CONDITIONS OFTEN ASSOCIATED WITH RURAL AND SURBURBAN HIGHWAY LOCATIONS, THE LIBERAL-MEDIAN DESIGNS ARE ECONOMICALLY COMPETITIVE WITH NARROW-MEDIAN DESIGNS AND DESERVE INCREASED CONSIDERATION BY THE HIGHWAY DESIGN TEAM. ANNUAL COSTS OF SELECTED INDEPENDENT ALIGNMENT AND NARROW- MEDIAN DESIGNS ARE PRESENTED FOR A RANGE OF COST AND TERRAIN FACTORS. SAFETY PERFORMANCE REQUIREMENTS ARE INCORPORATED IN A COMPARISON CHART THAT PERMITS RAPID, PRELIMINARY ECONOMIC EVALUATION OF TYPICAL ALTERNATIVE MEDIAN DESIGNS. /AUTHOR/
