Abstract

Accidents at the railway crossing intersection in the Mueang Nga area pose significant risks to the lives of the local population and the assets of government agencies in Thailand. This thesis aims to address this issue through the design of a safe and efficient railway crossing intersection in the Mueang Nga area of Lamphun Province. The research investigates the technical and operational requirements, urban and architectural design principles, and land use planning aspects of the railway crossing intersection. The study adopts a comprehensive research methodology, incorporating design principles and quality standards derived from Melbourne, Australia's Urban Design Framework - Measures and Qualitative Benchmarks. The data collection process includes surveys of the intersection's physical characteristics and traffic volume. Analysis techniques based on AASHTO and VicRoads guidelines evaluate the railway crossing, corner, and junction aspects. The study area is further analyzed using a standardized design approach, considering the railway track elevation, dimensions, column spacing, proportions, and perspectives. The study results demonstrate that the T.M. values obtained from the Mueang Nga railway crossing intersection survey exceeded the safety threshold of 100,000, affirming the urgent need for a grade-separated crossing at this location. Based on theoretical analyses and discussions, the research proposes design solutions that align with Melbourne, Australia's elevated railway track design standards, considering ten critical criteria. The objective is to enhance safety, efficiency, and visual integration at the railway crossing intersection to mitigate accidents and ensure seamless traffic flow. The recommendations from this research are expected to contribute to government agencies' efforts to create a safer and more livable environment. The proposed design solutions hold the potential for developing high-value areas, benefiting both residents and visitors. The emphasis on safety measures and improved efficiency at the railway crossing intersection is crucial in reducing accidents and enhancing the overall transportation system. This thesis offers insights into the design of railway crossing intersections, explicitly focusing on ensuring public safety and accessibility in local communities. Integrating these research findings into the design of main road networks, coupled with the conducted study, can significantly enhance road users' safety and potentially reduce future accidents.
