Abstract In Egypt, intersections are encountering congestion and safety problems. Midblock U-turns have been used for solving these problems. The midblock U-turn increased the accidents, besides, it has limited capacity. In the last decade, elevated U-turns have been applied to solve these problems. The extensive use of elevated U-turns has not been accompanied by any research for studying the performance of elevated U-turns with respect to safety and economy. This paper developed a simple framework for comparing elevated and traditional midblock U-turns in terms of safety and economy. The study applied a case study to evaluate the two alternatives using a benefit-cost analysis technique. Although the results show the high cost of the elevated U-turns, it has been demonstrated to be the best solution since they provide the greater traffic capacity and lower accident rates. Accident number reported at elevated U-turns was 59 % less than the number associated with traditional U-turns.

Transportation Agencies

Transportation research projects are a vital element for transportation agencies to accumulate new technology and knowledge to improve the efficiency and safety of transportation infrastructure. The purpose of this paper is to develop benefit cost analysis (BCA) tools to assist transportation agencies in evaluating transportation research projects. The BCA tools provide analysis methods for estimating the benefits for changes in the level of service (LOS) of a roadway, reductions in the vehicle travel time, changes in vehicle operating costs and reductions in the number of crashes. Three case studies were investigated to illustrate the usage of the BCA tools. The first case study evaluated the effectiveness of variable speed limit systems implemented along I-80 in southern Wyoming. The BCA tools estimated a benefit cost ratio of 6.64 indicating that the implementation of the project was economically justifiable. The second case study was a recent study investigating and developing mitigation strategies for the effects of truck traffic along the I-80 in southern Wyoming resulting in a benefit cost ratio of a 9.23 indicating that the project had the potential to be economically viable upon implementation. The final case study evaluated the effect of wildlife overpass and underpass crossings on the migrations of pronghorn and mule deer. The benefit cost ratio for the research project was 0.42 indicating that the project was not economically beneficial after the first year of implementation. The case studies indicated that the BCA tools are a beneficial tool for quantifying the economic benefits of a transportation research project.

A survey study was conducted to study the benefit-cost analysis of apiculture enterprise in Jutpani VDC, Chitwan district. Data were collected by interviewing randomly selected 18 beekeepers for sample survey. Benefit : Cost (BC) ratio of apiculture was computed by including and excluding the revenue obtained from colony selling. Only 61.11% of beekeepers sold bee colonies for earning income. The study revealed that BC ratios of apiculture were 2.41 and 1.58 in the case of inclusion and exclusion of the income received from the colony selling, respectively. It showed that apiculture industry was running in profit in both cases. In the former case, the BC ratio ranged from 0.97 to 6.22 and about 88.88% beekeepers were in profit. The BC ratio in the later case ranged from 0.43 to 3.41 and about 77.77% beekeepers were in profit. The number of colonies ranged from 2 to 54 with an average of 21.33 colonies per bee farm. In the former case, average annual income was Rs. 70758.33 (US$ 969.29 approximately) per farm and Rs. 49588.31 (US$ 679.29 approximately) in the later case. Likewise, the average income per colony per annum was Rs. 3317.31 (US$ 45.44) and Rs. 1777.65 (US$ 24.35 approximately) in the former and later case, respectively.

Benefit Cost

U.S. railroad accident rates have declined substantially since the 1980s; however, further improvement in train safety remains an important objective of the railroad industry. In this paper, we describe a framework developed to assess the cost-effectiveness of railroad infrastructure improvement to reduce railroad train accidents. Higher FRA track classes have been shown to be statistically correlated with lower accident rates, thereby indicating potential safety benefits. However, such infrastructure improvement also increases both capital and operating costs for track maintenance. We use accident data from the U.S. DOT Federal Railroad Administration (FRA) accident database and cost data from several recent U.S. railroad infrastructure maintenance projects presented in an FRA report to quantitatively evaluate the safety benefits and costs associated with infrastructure improvement decisions. Our model is intended to consider the trade-off between reduced accident rates and increased costs in evaluating railroad risk reduction strategies and operational decisions. The benefit-cost analysis framework is illustrated by considering the upgrade of track class 3 to class 4 in a hypothetical case study.
