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

Most studies of transit-induced gentrification rely on statistical analysis that measures the extent to which gentrification is occurring. To extend and enhance our knowledge of its impact, we conducted sixty-five interviews with residents living along the light rail transit (LRT) corridor in Waterloo Region, Ontario, Canada, shortly before the system opened. There was already strong evidence of gentrification, with more than $3 billion (Canadian dollars) worth of investment, largely in condominiums, before a single passenger was carried. In line with contemporary critical conceptualizations of gentrification, our interviews identified new and complex psychological, phenomenological, and experiential aspects of gentrification, in addition to economic- or class-based changes.

The Impact

Near-fault (NF) earthquakes cause severe bridge damage, particularly urban bridges subjected to light rail transit (LRT), which could affect the safety of the light rail transit vehicle (“light rail vehicle” or “LRV” for short). Now when a variety of studies on the fault fracture effect on the working protection of LRVs are available for the study of cars subjected to far-reaching soil motion (FFGMs), further examination is appropriate. For the first time, this paper introduced the LRV derailment mechanism caused by pulse-type near-fault ground motions (NFGMs), suggesting the concept of pulse derailment. The effects of near-fault ground motions (NFGMs) are included in an available numerical process developed for the LRV analysis of the VBI system. A simplified iterative algorithm is proposed to assess the stability and nonlinear seismic response of an LRV-reinforced concrete (RC) viaduct (LRVBRCV) system to a long-period NFGMs using the dynamic substructure method (DSM). Furthermore, a computer simulation software was developed to compute the nonlinear seismic responses of the VBI system to pulse-type NFGMs, non-pulse-type NFGMs, and FFGMs named Dynamic Interaction Analysis for Light-Rail-Vehicle Bridge System (DIALRVBS). The nonlinear bridge seismic reaction determines the impact of pulses on lateral peak earth acceleration (Ap) and lateral peak land (Vp) ratios. The analysis results quantify the effects of pulse-type NFGMs seismic responses on the LRV operations' safety. In contrast with the pulse-type non-pulse NFGMs and FFGMs, this article's research shows that pulse-type NFGM derail trains primarily via the transverse velocity pulse effect. Hence, this study's results and the proposed method can improve the LRT bridges' seismic designs.
