Abstract

This quantitative study aims to develop a data-driven framework for optimizing infrastructure investments in Myanmar’s Central Region, identified as a prospective economic hub. Integrating the Cobb-Douglas Production Function, Ridge Regression, and Composite Index Analysis, the framework systematically evaluates four key economic inputs: private capital, labor, transport infrastructure, and public infrastructure and GDP output. Ridge Regression addresses multicollinearity in government budget data, improving stability and reliability of coefficient estimates, while the Composite Index aggregates these inputs into a single metric of economic potential. Findings reveal that the Central Region scores highest, highlighting its readiness to become Myanmar’s next economic hub through strategic infrastructure investments. This robust methodology surpasses traditional models by providing policymakers with a practical tool to reduce regional disparities and prioritize high-impact investments. The study’s implications extend beyond Myanmar, offering a scalable model adaptable for other developing economies facing similar infrastructure and growth challenges.

Abstract

This research explores the use of rubberized concrete composite as an innovative structural material designed to improve energy dissipation and enhance seismic resistance by incorporating recycled rubber crumb into concrete. A reference test model was constructed using normal concrete, while the remaining models were made from concrete in which a portion of the fine aggregates was partially replaced with crumb rubber particles. Lumped mass columns were tested on a shaking table using sine wave excitation to evaluate dynamic behaviour and seismic response with 4 Hz sinusoidal base motion. Acceleration measurements were obtained and analysed in MATLAB using Fast Fourier Transform (FFT), allowing for comparison between normal and rubberized concrete specimens. The results indicated that as the rubber content in the concrete increased, the frequency of the columns decreased under base excitation. Additionally, three-dimensional finite element simulations of lumped mass column models were conducted in ANSYS. Linear dynamic analysis was conducted to assess the system’s behaviour when subjected to harmonic loading. In addition, resonance conditions were also considered to assess the dynamic interaction of the column. With higher rubber content, the acceleration response is reduced due to the enhanced damping and energy absorption capabilities of rubberized concrete, leading to a significant decrease in peak acceleration values.

Abstract

Public bus transport is the dominant travel mode in Yangon, serving millions of daily commuters and playing a vital role in urban mobility. This study presents a GIS-based coverage analysis of public bus services in Yangon City to evaluate spatial accessibility and identify service gaps within the transit network. Service effectiveness is assessed using coverage indicators, including service area buffers, population coverage ratios, and accessibility indices. The results show that central townships, such as South Okkalapa Township, Yankin Township, and Thaketa Township, achieve high coverage levels exceeding 80%, while peripheral areas, including Mingalardon Township and Dagon Myothit Township, remain below 40%. Heat map analysis highlights dense coverage in the central business district and surrounding areas, contrasted with limited accessibility in outer regions such as Hlaingtharyar Township. Key service gaps are also identified along major corridors like Parami Road and Bayint Naung Road. The study reveals significant spatial inequalities in transit accessibility and provides a data-driven basis for improving sustainable urban transport planning.
