With the growing focus on sustainable development, light rail transit (LRT) systems are increasingly viewed as key drivers of low-carbon mobility and spatial equity. However, as urban spatial structures become more stable, it remains unclear whether LRT systems can still enhance quality of life, property values and contribute to inclusive urban regeneration. This study explores Manchester, Sheffield, and Nottingham, three UK cities with recent LRT development experience, as case studies. Using LRT constructed or expanded between 1995 and 2019 as a quasi-natural experiment, a difference-in-differences (DID) model is applied to estimate the causal impact of LRT expansion on property prices. The results indicate that LRT construction can lead to a 4.44% to 8.29% increase in nearby property values, with a lagged effect observed after implementation. The impact is more pronounced in areas with well-developed bus networks and in lower-income areas. Further mechanism analysis suggests that the effect is indirectly driven by improved accessibility and enhanced convenience of access to local amenities.

This paper explores sustainable urban mobility and infrastructure in Sub-Saharan Africa, focusing on engineering pathways that contribute to climate mitigation and inclusive development. Rapid regional urbanisation has resulted in congestion, inadequate public transportation, and environmental degradation that require innovative solutions to diverse regional contexts. Through an analysis of successful initiatives across the continent, the study highlights models that demonstrate the transformative potential of engineering innovations. These include Dar es Salaam’s Bus Rapid Transit (BRT), Kigali’s non-motorised transport infrastructure, Addis Ababa’s Light Rail Transit (LRT), and Lagos’ Waste-to-Wealth program. Additional examples illustrate regional diversity: Cape Town’s renewable energy integration as a driver of sustainable urban energy transitions in Southern Africa; Kampala’s flood-resilient infrastructure systems, which address climate-induced urban flooding in East Africa; and selected Central African cities such as Douala and Kinshasa, which have implemented drainage improvements, waste-to-energy pilots, and informal settlement upgrading to reduce climate risks and enhance urban resilience. The study finds that integrated urban planning, efficient public transport, renewable energy adoption, and climate-resilient infrastructure are central to building sustainable and inclusive cities. Policy recommendations emphasize renewable energy investment, expanded non-motorised transport, strengthened public-private partnerships, and community participation. By fostering inclusivity, reducing greenhouse gas emissions, and enhancing resilience, Sub-Saharan African cities can make significant progress toward achieving the Sustainable Development Goals (SDGs). Ultimately, the paper concludes that strategic policy interventions, engineering innovation, and multi-stakeholder collaboration are essential for shaping equitable, climate-resilient, and future-ready African cities.

This study investigates perceived transit-induced gentrification (TIG) in anticipation of the Maryland Purple Line light rail transit among residents of Prince George’s County, Maryland, and its associations with walkability and crime. In spring 2021, Wave I of the GENTS Study collected data through an online questionnaire on residents’ perceptions of the Purple Line and related neighborhood factors. Using exploratory factor analysis and multiple linear regression, we examined the relationships between perceived TIG, walkability, and crime. In a sample of 465 respondents, primarily Black/African American (61%) and White (28%), walkability factors such as accessibility and a pedestrian-friendly environment were significantly associated with positive TIG perceptions. In contrast, concerns about house break-ins, purchasing a gun, and walking barriers were linked to negative TIG perceptions. These findings contribute to a deeper understanding of the complex dynamics between urban development, gentrification, and social determinants of health.

The feasibility of suburban single-track laterally positioned light rail transit lines in the modern United States

ABSTRACT This study investigated the factors that strengthen the capacities of local advocacy coalitions to achieve their urban transport policymaking objectives, as well as how the roles of policy brokers influence this policy in the Thai cities of Khon Kaen, Chiang Mai, and Phuket. This study draws upon a novel policy broker analysis framework that developed from the Advocacy Coalition Framework to investigate relevant factors and roles of policy brokers in those selected cases. The research utilizes the case study research as the primary methodology in which 39 key informants were interviewed in order to gather data from the local private, public, and civic sectors in those selected cities. The author applied the CAQDAS technique, which deploys Atlas.ti to analyse the qualitative interview data. The study identifies seven key factors contributing to the strength of local advocacy coalitions: the roles of policy brokers; political dynamics; financial resources; collaboration across local alliances; local government engagement; coalition unity; and the ability to integrate external events. These factors were found to be most effectively leveraged in Khon Kaen, where the local coalition was able to achieve its policy objectives, whereas the coalitions in Phuket and Chiang Mai were less effective. Moreover, the research highlights the pivotal role of private-sector policy brokers, whose financial and political resources significantly enhanced coalition capacity in Khon Kaen. These brokers exhibited advanced strategies for managing and coordinating local collective efforts to advocate for Light Rail Transit (LRT) policy. In Phuket, the influence of policy brokers was moderate, while in Chiang Mai, it was largely absent. The findings suggest that the roles and resources of policy brokers are critical for successful transport policymaking. This explains why the coalition in Khon Kaen succeeded, while those in Phuket and Chiang Mai did not.

ABSTRACT Transit Signal Priority (TSP) is a control strategy that can reduce the delay of transit systems. However, upon a high traffic volume, TSP may significantly increase delays for non-prioritized vehicles. Furthermore, designing TSP without considering signal coordination may result in ineffective progression for transit vehicles. In recent years, V2X (Vehicle-to-Everything) communications have been built and tested to collect vehicles’ locations and speeds. This study seeks to develop a coordinated TSP control logic in a V2X environment, where additional delays caused by TSP control are calculated with queue length prediction. By adopting a dynamic programming algorithm, the waiting time of transit vehicles and overall delays along the transit route are accounted for to determine the optimal TSP action. The simulated experiment based on a Light Rail Transit (LRT) system shows that the V2X coordinated TSP effectively mitigates the negative impact on general vehicles in non-priority directions upon heavy traffic flows.

Abstract Kobe's downtown area is currently planned for redevelopment projects that include the introduction of Light Rail Transit (LRT) and the construction of new facilities. This study advances the pedestrian model by developing a system that allows agents to choose between walking and LRT as the modes of transportation. We employ an MAS to analyze the effects of LRT implementation and redevelopment on pedestrian circulation, measured by five key indicators: average walking time, average walking distance, number of destinations visited, LRT travel time, and expenditure. Additionally, the impact on the local economy is assessed through the total visitor count and expenditure. The simulation results reveal that the introduction of LRT activates circulation behaviors, whereas the effects of redevelopment on circulation behaviors are limited. However, the results of the simultaneous introduction of LRT and redevelopment indicate increases in the five key indicators and total number of visitors, compared with the current state. Therefore, combining LRT and redevelopment can lead to increased pedestrian circulation and the revitalization of the local economy in the long term. The future challenge is to analyze the impacts of different routes, station locations, fares, service frequencies, and the characteristics of pedestrians on their movement patterns, in order to propose more effective planning strategies.

The increasing number of vehicles in Jakarta, Indonesia, has had a negative impact on the environment. If this trend continues, it may significantly harm public health. In response to this issue, the government has introduced mass transportation solutions, such as the Jabodebek light rail transit (LRT) system. One of the key technical challenges in operating the LRT is ensuring smooth and reliable traction motor control. This study presents a simulation of the Jabodebek LRT’s traction motor performance when traversing a hilly route with a 29 ‰ gradient. A field-oriented control (FOC) method is implemented to regulate motor speed. The train operates under a constant load, with its weight gradually increasing from the lowest to the highest point of the slope. Two tuning methods are applied to optimize the controller parameters: manual (hand-tuning) and artificial intelligence-based optimization using the Firefly algorithm and the Grey Wolf optimizer (GWO). The integral of time multiplied by absolute error (ITAE) is used as the objective function to evaluate the speed control performance. The simulation results show that the Grey Wolf optimizer delivers the best performance, achieving stable speed control despite load disturbances. The optimal proportional and integral gains obtained are Kp = 16.233861 and Ki = 0.526774, respectively.

A noise impact assessment was carried out in 1991 for the Dallas Area Rapid Transit (DART) South Oak Cliff (SOC) light rail transit (LRT) Blue Line along Lancaster Road in Dallas, TX in accordance with guidelines that were applicable at the time. This assessment did not account for noise from audible warning devices (AWD) and did not identify noise impact. However, in response to the high frequency of collisions along this corridor after the Blue Line went into operation, train operators were required to sound the horn at each at-grade crossing along the Lancaster corridor. Due to noise complaints resulting from this rule modification, the Dallas City Council requested noise mitigation for a residential area along Lancaster Road. In response, DART conducted a reassessment of noise impact based on existing train operating conditions using current U.S. Federal Transit Administration (FTA) guidelines. The reassessment was based on measurements of existing noise conditions in the study area and measurements of AWD noise from a DART light rail vehicle (LRV). Comparing estimates of noise exposure from current LRT operations with estimates of background noise exposure from traffic on Lancaster Road, noise impacts were identified using FTA criteria and mitigation measures were investigated.

ABSTRACT In this study, an experimental and fatigue simulation is designed to investigate the fatigue life of R260 rail for light rail transit. Specifically have two parts in experiment, begin in tensile test to examine the value of UTS, yield strength and break elongation for R260 material behaviour using UTS machine below 250kN through three specimens. In second part, the type of Servo-Pulser fatigue machine was performed of less 100 kN with using frequency of 10Hz based on 20% to 80% separately as below value on UTS of 1145 MPa to identify fatigue life under stress ratio of R = −1 to generate S-N curve. The results of the experiment show that the endurance limit occurs at 20% and 30% stresses loading below 372 MPa, the regime of HCF fall into 40%untill 70% ranges at 103-105 cycle to failure and LCF occur of 80% ranges at 102 cycle to failure. In fatigue simulation, the results of fatigue limit is below 372 MPa of 20% and 30% and the fatigue failure fall into 103-105 cycles period in stress ranges in between 372 MPa to 763 MPa. Both results gives a good agreement correlation to prove feasibility and reliability in terms of creation R260 databases.

Light Rail Transit (LRT) is one form of mass transportation using light rail train that reflect towards sustainable development has been planned by the South Sumatera local government. The benefits of LRT is to overcome the problem of traffic congestion using diversion for private vehicles users, to be mass transportation users, especially in the City of Palembang. LRT has become an alternative mode of transportation that is accessible, punctual, and it has a separate pathway from the existing transporting roads. The Light Rail Transit (LRT) in Palembang was built in 2018 as a form of development from the South Sumatra Provincial government for the 2018 Asian Games, the Southeast Asia regional sporting competition. Presenting LRT as a solution to traffic problems through sustainable development by the regional government to realize the concept of transit-oriented development (TOD)). The purpose of this study is to interogate the application of TOD in Palembang City, especially in the existence of LRT based on methods and approaches using TOD Indicators, such as: diversity, destination accessibility, distance & design, and demand management to encourage and realize the concept of transportation and development of Palembang City which is sustainable.

Contact stress arises in the wheel-rail because of the load imposed on the wheel. This stress on wheel leads to wear, distortion, and damage, increasing maintenance or replacement costs. This study primarily evaluates stresses in wheel-rail contact utilizing the FEM method to compare existing and newly developed wheel materials for their load-carrying capacity. A three-dimensional finite element analysis model of a wheel-rail system was created, and stress at a contact patch is calculated by applying a load. The study examines how the composition and hardness of materials affect stress distribution in wheel-rail contact. The composition of silicone, manganese, and carbon is increased to 0.5, 0.7 and 0.25% for the current wheel and to 0.8, 1.15 and 0.38% for the alloyed wheel. With a 0.82% increase in hardness for the alloyed wheel, the maximum equivalent (von-Mises) stress was found to be 0.26124 MPa for the existing wheel and 0.12907 MPa for the alloyed wheel. Finally, the result showed that the maximum deformation for the existing wheel was 0.0001225 mm, while for the alloyed wheel, it was 7.3088e-5 mm. Therefore, Addis Ababa Light Rail Transit and similar railway companies should consider the result of this study to improve their operations.

Due to recent urbanization and population growth in cities, the passenger transport system is faced with significant congestion and delay problems. In particular, to handle peak-time passenger traffic, railway public transport systems are operated with more frequent trips during the peak hours, and less-frequent train interarrivals are scheduled during off-peak hours to increase the total system utilization. This study proposes a simulation methodology for optimizing the trips of a metro line with variable passenger traffic. A microsimulation model was constructed using the Arena software to create an experimental medium for the optimization phase. The discrete-event simulation concept was utilized for the model building. The passenger flow and train arrival rates were the main input parameters obtained from the passenger origin-destination station matrix and train arrival data. The model was coupled with the artificial bee colony algorithm for determining the optimized train time headways. The optimization study resulted in a decrease of 27.5% and 25.5%in the total number of daily train trips for the normal and increased train capacity scenarios under a zero failed boarding policy. The results of the study were also compared with the literature findings which are discussed in detail.

Palembang has three main modes of transportation operating separately: river transport, Bus Rapid Transit (BRT), and Light Rail Transit (LRT). Although these modes have great potential to complement each other, the lack of proper integration results in inefficiencies in public transportation services. This study employs a qualitative approach using descriptive methods. This approach is chosen to describe and analyze the actual conditions and potential integration between river transport, Bus Rapid Transit (BRT), and Light Rail Transit (LRT) in Palembang. Data were collected from field observations, in-depth interviews with relevant stakeholders, and literature studies. Based on the integration performance measurement, the Modal Interaction Matrix resulted in a Normalized Score of -200, which falls into the poor category. Several key challenges were identified, including unintegrated infrastructure, unsynchronized operational schedules, and separate ticketing systems.

The security of the Light Rail Transit (LRT) system is a significant concern as its utilization continues to grow in Indonesia. As a viable solution to urban congestion, the LRT encounters various challenges, including cyberattacks and technical issues that could disrupt operations and jeopardize passenger safety. This study aims to analyze these threats and propose solutions using the ISO-31000:2018 framework. The research employs a Systematic Literature Review (SLR) methodology to assess risks based on their likelihood and potential impact. The findings indicate that the primary threats include phishing attacks, ransomware, and signal system failures. However, this study has limitations, as it is based exclusively on secondary data, which may not fully reflect local conditions. The originality of this research lies in its application of ISO-31000:2018 within the local context and its provision of practical recommendations for operators and policymakers. Moreover, it paves the way for future studies to conduct more comprehensive, field-based research.

ABSTRACTActive transportation (AT) has become increasingly important due to its positive impacts on public health, reducing emissions, and promoting sustainable urban environments. This study examines how Light Rail Transit (LRT) stations in Edmonton, Canada, contribute to encouraging AT by evaluating nine criteria within three key categories: infrastructure availability and connectivity, safety and security, and comfort and aesthetics. The Criteria Importance Through Inter‐criteria Correlation (CRITIC) method was used to determine the weight of each criterion, followed by the Weighted Sum Model (WSM) to rank stations, calculate scores, and identify areas in need of enhancement. An equity analysis was conducted to evaluate whether the distribution of LRT stations disproportionately benefits specific demographic groups. The findings reveal that 75% of sidewalks within a 400‐m buffer were of good quality, yet 12% of the area was unsuitable for walking. Moreover, 74% of streets within an 800‐m buffer lacked designated bike lanes. The distribution of intersection types within station areas included 46% cross intersections, 38% T‐intersections, and 16% cul‐de‐sacs. Furthermore, station scores, which range from 0 to 1, varied significantly, with Downtown stations such as Bay Enterprise Square (0.873) and Central (0.778) ranked highest, while suburban stations like NAIT Blatchford Market Station (0.044) and Davies (0.124) ranked much lower. This study highlights the necessity of focused improvements in AT infrastructure, particularly in outlying areas, to enhance the overall effectiveness of the LRT network. These insights are valuable for urban planners seeking to develop a more accessible and sustainable transportation system.

Determining the Relationship between Land Use Characteristics and Passenger Ridership of Light Rail Transit Lines in Kuala Lumpur

The emission and mitigation of greenhouse gases transforms the status of urban environ ments. However, a policy accounting for all the aspects associated with transport is lacking. Prob lems related to transport include a greater reliance on cars, increased congestion, and environmental impacts. The absence of an efficient public transport system is a notable cause of the prompt escala tion of diverse problems, for example, increases in the number of personal automobiles causes con gestion on the road, resulting in air pollution, ubiquitous greenhouse effects and noise pollution, which ultimately affect human health. Over the past two decades, a growing number of communities have pursued light rail transit (LRT) and Transit-Oriented Developments (TODs) as part of an integrated transportation and land use strategy to revitalize and/or regenerate the built environment of worldwide cities. Green TOD focuses on combining TOD with green neighborhood to generate larger ecological and environmental benefits. In their research, Cervero and Sullivan suggested that the combination should be realized in the following aspects: (1) higher densities, (2) mixed land use, (3)reduced. The integration of Blockchain with BIM for data provenance uses a distributed network for storing provenance data over a decentralized and fault-tolerant ledger With the results of this research, there is expected to be shared awareness and concern about implementing green neighborhood and green space as an initiative to present a more energy-efficient transit oriented, save operating costs, and provide comfort to customers.

This study examines the application of collaborative governance in the management of Light Rail Transit (LRT) services in Palembang City, Indonesia. Using Emerson and Nabatchi's collaborative governance framework integrated with a multi-helix approach, this research analyzes the dynamics of collaboration between various stakeholders in the provision of LRT services. Through qualitative analysis of interviews with key stakeholders, this study identified significant challenges in collaborative processes, including uncontrolled uncertainty, inadequate interdependence, limited consequential incentives, and inadequate initiative leadership. Research findings reveal that weak principal engagement, limited shared motivation, and uneven capacity for joint action have hindered effective collaboration. This research contributes to the literature on collaborative governance in public transport management and provides practical recommendations for improving LRT services through increased stakeholder collaboration.
