This paper aims to improve the implementation standards of solar-energy-based street lighting in Indonesia. A model framework was developed to assess existing conditions regarding the level of lux, the distance between poles, pole height, and lamp power. According to the evaluation of the existing circumstances, the street lighting system is not satisfactory according to the national standard, with 64.7% black area. An alternative installation of street lighting designed by DIALux application was proposed to fulfill the technical standard of street lighting. The result shows that this alternative design can be used for renewing existing street lighting with better performance and reliability. Economic analysis of all technically feasible alternatives was conducted afterward by benefit–cost analysis. The analysis shows that solar-energy-based street lighting requires as much as 621,473,620.00 Indonesian Rupiah (IDR), with 1.06 benefit–cost ratios and a 9% reduction of total cost. Therefore, the analysis indicates that solar-energy-based technology can be feasibly implemented in a street lighting system. The results show that the proposed model can be applied to improve the implementation standard of solar-energy-based street lighting.

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.

Benefit Cost

Statements concerning rangeland degradation and restoration issues are often supported by technically oriented evaluations, with limited consideration of the economic implications of resource conservation or rehabilitation. In the few cases where an attempt has been made to incorporate economic elements into analyses, some shortcomings have been evident in the methodology adopted. This has sometimes produced misleading results, and has made comparisons of different restoration technologies difficult. This paper examines several issues that are important in obtaining an economic perspective on the restoration of degraded rangelands. The formal procedure of benefit-cost analysis is presented as a rational framework for the economic evaluation of such activities. The framework is applied, via a case study approach, to examine the private economic value of several technologies for rangeland restoration. However, because the analysis is based on limited data, the conclusion is indicative rather than definitive. Issues relevant to the extension of the analysis to encompass social evaluations of rangeland restoration management are canvassed.

The economic assessment of transportation projects is evolving from a reliance on user benefits (travel time, cost, or safety) to encompass a wider spectrum of potential benefits, fostered by advances in economics and recognition that different project modes deliver different portfolios of benefits. Sponsors develop projects to address specific problems in their communities. This progression in how investments are evaluated opens the door for projects whose outcomes span a variety of benefit categories rather than concentrating on traditional user benefits and permits an improved intermodal comparison of candidate investments. Transit and intercity rail projects are particular beneficiaries of the broader project assessment approach. This paper presents a case study of how a comprehensive approach to project assessment was applied to the Northern Lights Express project that would reintroduce passenger rail service between the cities of Minneapolis and Duluth, Minnesota, the state's largest economies. Owned and operated by BNSF Railway, Amtrak's service in the corridor ended in 1985. Six stations are planned: Target Field in Minneapolis; stations in Coon Rapids, Cambridge, and Hinckley, Minnesota; a station in Superior, Wisconsin; and Union Depot in Duluth. The goal for the analysis was threefold: ( a) to confirm that the investment would yield a positive return; ( b) to communicate with partners, stakeholders, and the public about the project's expected outcomes; and ( c) to contribute to the selection of an alternative. The benefit–cost ratio was estimated for eight alternatives that varied by physical alignment and service plan.

In this work, we present a technical and economic study of the solar powered street lighting system of a municipality in the south of Morocco. The state of the conventional street lighting system is first analyzed in a substation of street lighting. Then a sizing method is applied to the photovoltaic installation in the testing area. A financial study, by comparison between conventional and PV-based lighting, is carried out showing the feasibility of the PV street lighting.
