Technical Evaluation

ABSTRAKLight Rail Transit (LRT) kini menjadi salah satu sarana transportasi darat yang sedang direncanakan untuk memenuhi kebutuhan transportasi pada suatu kota yang memiliki tingkat kepadatan penduduk yang tinggi. Di wilayah Bandung Raya telah ada rencana jalur LRT yang disusun oleh Dinas Perhubungan Provinsi Jawa Barat yang terdiri atas delapan koridor. Pada penelitian ini dilakukan evaluasi teknis rencana jalur LRT khususnya pada koridor-1 (Leuwi Panjang–Jatinangor) dan koridor-4 (Leuwi Panjang– Babakan Siliwangi). Tujuan dari penelitian ini adalah mengevaluasi tingkat kesesuaiannya dengan persyaratan teknis jalur kereta api, khususnya terhadap aspek geometrik yaitu kelandaian dan kelengkungan. Evaluasi dilakukan dengan melakukan analisis geometrik pada rencana jalur LRT dengan persyaratan teknis jalur kereta api terhadap lima kelas jalan rel. Berdasarkan hasil analisis diketahui bahwa pada koridor-1 sudah memenuhi persyaratan kelandaian dan lengkung horizontal untuk semua kelas, sedangkan koridor-4 belum memenuhi persyaratan tersebut.Kata Kunci: Light Rail Transit (LRT), kelandaian, lengkung horizontalABSTRACTLight Rail Transit (LRT) now become one of transportation means to fullfil the need of transportation in one of regions which is having high population. In Bandung Raya region, there were plans of LRT line which is arranged by Dinas Perhubungan West Java Province which consist of eight coridors. This research has done the technical evaluation for planning the LRT especially on corridor-1 (Leuwi Panjang- Jatinangor) and corridor-4 (Leuwi Panjang-Babakan Siliwangi). The aim of this reasearch is to evaluate the appropriateness levels with the rules and regulations of train technical lines, especially on the aspec of geometric including slope and horizontal curve. The evaluation is done by doing geometric analysis in the plan of LRT line with rules and regulations of train technical line toward five classes of rail line. Based on the result of analysis, it can be revealed that corridor-1 has been fullfil the rules and regulations of slope and horizontal curve for every classes, while corridor-4 do not fullfil the rules and regulations yet.Keywords: Light Rail Transit (LRT), slope, horizontal curve

Laterally Loaded

A design procedure was developed for a relatively unknown slope stabilization technique consisting of a series of parallel sheet piles installed parallel to the direction of slope movement. This technique was introduced in Alberta by R.M. Hardy in the 1970s and is locally referred to as “Hardy Ribs.” A case study is discussed where Canadian National (CN) Rail installed Hardy Ribs to stabilize a landslide affecting its rail line in western Manitoba. A proposed design procedure is discussed that consists of a de-coupled approach with a separate limit equilibrium slope stability analysis and laterally loaded pile analysis using p–y curves, where p is the soil reaction per unit length and y is the lateral deflection of the pile, to model the soil–pile interaction. Example calculations are provided for the proposed design procedure for the CN case study site to illustrate its use and to estimate the stabilizing effect from the Hardy Ribs at this site.

The South

The facts, figures, and inferences in chapter 7 regarding municipal behavior toward transit-oriented housing opportunities illustrate many points. Still, there is much that even a careful statistical analysis might miss or misunderstand. For that reason, we also explored what we could learn by talking to real planners about these issues. The case of San Diego is interesting and useful for several reasons. First, the San Diego Trolley is the oldest of the current generation of light rail projects in the United States. Unlike many newer systems, the age of San Diego’s rail transit (the South Line opened in 1981) allows time for land use planning to respond to the fixed investment. Second, the San Diego system is no stranger to modern transit-based planning ideas. The San Diego City Council approved a land-use plan for their stations that includes many of the ideas promoted by transit-oriented development (TOD) advocates (City of San Diego, 1992). Third, the light rail transit (LRT) authority in San Diego County, the Metropolitan Transit Development Board (MTDB), is often regarded as one of the more successful municipal LRT agencies. The initial parts of the MTDB rail transit system were constructed strictly with state and local funds, using readily available, relatively low-cost technology (Demoro and Harder, 1989, p. 6). Portions of San Diego’s system have high fare-box recovery rates, including the South Line, which in its early years recovered as much as 90 percent of operating costs at the fare box (Gómez-Ibáñez, 1985). All of these factors make San Diego potentially a “best-case” example of TOD implementation. When generalizing from this case study, it is important to remember that the transit station area development process in San Diego is likely better developed than in many other urban areas in the United States. The results from San Diego County can illustrate general issues that, if they have not already been encountered, might soon become important in other urban areas with rail transit systems. Also, given San Diego County’s longer history of both LRT and TOD when compared with most other regions, any barriers identified in San Diego County might be even more important elsewhere.

Research often finds a positive relationship between public transportation investment and gentrification in nearby neighborhoods. This dynamic is particularly important in urban contexts that plan for transit-oriented development and creating future “walkability.” In this study, I demonstrate a link between transit investment and changing neighborhood racial and ethnic composition, using a case study of the recent light-rail project in Seattle, Washington. Descriptive analyses and difference-in-difference models suggest that affected neighborhoods in Seattle experienced rising shares of non-Hispanic Whites following the start of light-rail construction, while neighborhoods at the suburban periphery of the line saw substantial growth in racial and ethnic diversity. These findings highlight the role of transit infrastructure in restructuring demographic trajectories of nearby neighborhoods and contribute evidence about shifting patterns of residential segregation in the area around the transit line.

The public transport system of Karlsruhe, Germany, in particular its innovative services on jointly used heavy rail lines, has received substantial attention throughout the last 2 decades. The discussion of the system and of its development was rather limited in the past, mostly highlighting technical aspects. An overview is provided of the development, including the urban development of the region, and of the funding system. The ridership and financial development of the operator is documented in detail. Case studies focus on the integration of the system development in the general political process of the region and demonstrate the limitations of the operator under its current ownership structures.

This article primarily aims to understand how the Light-Rail Transport (LRT) pricing and infrastructural innovations from a Chinese context have been adopted to the Addis-Ababa city context. Secondly, it wishes to show what were the economic, social, and environmental effects of these adapted innovations on passenger service delivery and Multi-National Corporations (MNCs), and what effects the resident’s proximity had on commercial activities along the LRT route. Thirdly, it identified re-adaptations to a more sustainable LRT with respect to the passengers, MNCs, and residents. This study has revealed economic, social, and environmental effects that may influence innovation adoption, such as the following: reduction in carbon emissions; fare evasion; inconvenience; affordability; less revenue; less proximity to commercial activities; and an increase in travel distances for pedestrians. A mixed method for a single case study was used, including semi-structured interviews with light-rail experts and a passenger survey. The results show that economic sustainability factors account for 12 out of 14 sustainability factors and 2 out of 14 social and environmental sustainability factors. The results are intended to be used as a decision support system for innovation adoption in other cities with similar context, in order to develop a sustainable approach to LRT planning.
