- W631648935 abstract "Two way left turn lane (TWLTL) medians are a common solution to the safety and operational problems on four lane undivided roadways that result from conflicts between through and left turning traffic. Although the potential safety and operational effects of TWLTL medians are well recognized, no generally accepted guidelines define the circumstances under which the costs of TWLTL medians are justified by the benefits they provide. The objectives of this research were: (1) to evaluate the safety and operational effects of TWLTL medians on urban four lane roadways, (2) to develop a methodology for evaluating their cost effectiveness, and (3) to use this methodology to develop guidelines for their cost effective use. The formulation of the cost effectiveness methodology was based on a benefit cost analysis. The benefits were the accident and operational cost savings provided by TWLTL medians. The costs were those of installing and maintaining them. TWLTL evaluation forms were designed to facilitate the implementation of the methodology. An analysis of the accidents on four lane sections of the state highway system in Nebraska was conducted to determine the safety effects of TWLTL medians. A computer simulation study was conducted to determine their operational effects. The results of these studies were incorporated into the cost effectiveness methodology. The cost effectiveness methodology was used to develop guidelines that indicate the ADTs, left turn percentages, and driveway densities at which TWLTL medians on urban four lane roadways are cost effective. Their development was based on conditions and costs representative of those on urban four lane roadways in Nebraska during 1986 (A)." @default.
