Evaluation of a Sustainable Urban Transportation System in Terms of Traffic Congestion—A Case Study in Taxila, Pakistan
A parking area emerges as the most sustainable solution to reduce traffic congestion at Taxila's intersection, according to a multi-method study combining fuzzy AHP-TOPSIS, fuzzy AHP-VIKOR, and traffic simulation software. Despite initial survey-based preferences favoring flyovers, on-site observations and literature reviews confirmed that expanding parking capacity would better address congestion while aligning with sustainable urban transportation principles. The research leveraged stakeholder input and advanced decision-making techniques to evaluate alternatives, offering actionable insights for Taxila's proximity to Pakistan’s economic hubs—Islamabad and Rawalpindi—while balancing infrastructure efficiency and environmental impact.
Traffic Flow Analysis and Solutions to Ease Traffic Flow at Unsignalized Taxila Intersection
A study at Taxila, Pakistan, identifies critical traffic congestion issues at unsignalized intersections along the N-5 highway, where complex roadway geometries exacerbate problems like accidents and high operational costs. The research quantifies these challenges through traffic flow analysis, aiming to assess system performance and its interaction with land use activities. By deriving actionable insights from traffic data, the study proposes solutions to improve efficiency, offering recommendations for policy changes and infrastructure adjustments—such as banning heavy vehicles during peak hours or expanding road capacity—to mitigate congestion and enhance safety.
Effect of dust deposition on the performance of photovoltaic modules in Taxila, Pakistan
Dust deposition significantly reduces the performance of photovoltaic (PV) modules, with monocrystalline silicon modules experiencing greater losses compared to polycrystalline ones. A three-month study in Taxila, Pakistan, found that dust accumulation at 0.9867 mg/cm² led to a 20% decrease in average output power for monocrystalline modules and 16% for polycrystalline modules, alongside efficiency drops of 3.55% and 3.01%, respectively. The research systematically measured the impact of dust on PV performance by comparing clean and dirty modules under natural atmospheric conditions, highlighting the critical need to address dust-related losses in renewable energy systems.
Mycobial Deterioration of Stone Monuments of Dharmarajika, Taxila
A study on the mycobial deterioration of stone monuments at Dharmarajika, Taxila, revealed that 19 fungal species, including Alternaria alternata, Aspergillus spp., and Cladosporium herbarum, contribute to biodeterioration through biofilm formation and organic acid production. These fungi secrete corrosive acids such as oxalic, citric, and acetic acids, which accelerate stone decay—a significant threat to the preservation of tropical heritage sites. The research highlights the role of microbial metabolism in monument degradation, emphasizing the need for targeted conservation strategies.
Outdoor testing of photovoltaic modules during summer in Taxila, Pakistan
A comparative analysis of photovoltaic (PV) module performance in Taxila, Pakistan, during summer revealed that monocrystalline silicon (c-Si) modules exhibited the highest average efficiency, while amorphous silicon (a-Si) modules outperformed others in terms of performance ratio. The study found a significant decrease in both efficiency and performance ratio with rising module temperatures, which were approximately 20°C higher in summer compared to winter months. This decline correlated with ambient temperature fluctuations ranging from 18.1°C to 38.6°C. The research utilized outdoor monitoring to assess actual operating conditions of c-Si, polycrystalline silicon (p-Si), and a-Si modules, offering critical insights into PV performance under Taxila's climate.
A Guide to Taxila
A comprehensive guide to the ruins of Taxila, this work reveals significant insights into the historical and topographical significance of the site. Led by Sir John Marshall, a renowned British archaeologist, the book combines detailed excavation findings with illustrative figures, a glossary of technical terms, and an extensive bibliography. It provides a concise yet thorough exploration of Taxila's architectural groups and their contents, offering valuable context for anyone interested in archaeology or the history of this UNESCO World Heritage Site.
Solid Waste Management Issues in Small Towns of Developing World: A Case Study of Taxila City
Taxila City faces severe solid waste management challenges due to rapid urbanization and industrialization. The study reveals that open dumping of municipal solid waste is causing significant environmental degradation, including land and water pollution, infectious diseases, and biodiversity loss. Key factors contributing to these issues include insufficient funding, poor waste management practices, non-implementation of legislation, and irresponsible behavior by residents. The research highlights the urgent need for improved waste management systems in small towns of developing countries to mitigate negative environmental impacts.
