Assessing Sustainability Practices in Urban Public Transportation: A Case Study of Metro Transit

Thesis Abstract

Urban public transportation systems play a critical role in promoting sustainable urban development by reducing congestion, lowering greenhouse gas emissions, and enhancing mobility equity. However, the extent to which transit agencies—specifically Metro Transit—implement and achieve sustainable practices remains underexplored, particularly in the context of increasing urbanization pressures and environmental challenges. This study aims to assess the sustainability practices adopted by Metro Transit, focusing on environmental, social, and economic dimensions, and to identify factors influencing their effectiveness. The specific objectives are to evaluate the environmental initiatives undertaken by Metro Transit, analyze their social inclusiveness and accessibility measures, assess economic viability and funding mechanisms, and propose an integrated framework for enhancing sustainability performance. The research adopts a mixed-methods approach, integrating quantitative survey data with qualitative interview insights to provide a comprehensive understanding of sustainability practices. The population comprises Metro Transit employees, policy-makers, and commuters, with a sample of 350 respondents selected through stratified random sampling to ensure representativeness across operational, managerial, and user groups. Data collection instruments include a structured questionnaire measuring perceptions of sustainability practices, supplemented by semi-structured interviews with 20 key stakeholders involved in policy formulation and implementation. The validity of the instruments is established through expert review and pilot testing, while reliability is verified via Cronbach’s alpha coefficients exceeding 0.75. Quantitative data are analyzed using descriptive statistics, regression analysis, and ANOVA to identify significant predictors and differences among respondent groups. Thematic analysis is employed for qualitative interview data, allowing extraction of nuanced insights into systemic challenges and opportunities. It is anticipated that the findings will reveal a predominantly environmentally driven sustainability framework within Metro Transit, characterized by investments in greener fleet technologies and energy-efficient infrastructure. However, social inclusiveness—such as fare affordability, accessibility for persons with disabilities, and service reliability—may require strategic improvements. Economically, the study expects to identify gaps in funding models, highlighting the tension between operational costs and fare revenues. The research hypothesizes that organizational commitment, policy support, and community engagement are significant predictors of sustainable practice implementation, supported by Institutional Theory and the Stakeholder Theory. The study aims to develop a conceptual model illustrating the interrelationships among these variables, serving as a basis for strategic enhancements. This research will contribute to existing knowledge by providing an empirically validated assessment of sustainability integration in urban transit systems, offering a transferable framework applicable to similar contexts globally. It advances scholarly understanding of the practical interplay between policy, organizational capacity, and operational practices in fostering sustainability within the public transportation sector. The findings are expected to inform policymakers and transit authorities on leveraging organizational strengths and addressing systemic gaps for sustainable development. The study concludes that while Metro Transit demonstrates a commendable commitment to environmental initiatives, significant improvements are required in social inclusiveness and economic resilience to achieve comprehensive sustainability. Recommendations include adopting integrated sustainability metrics, enhancing stakeholder engagement, diversifying funding sources, and expanding investment in accessible infrastructure. Additionally, the study advocates for periodic sustainability audits and capacity-building programs to embed sustainability into the organizational culture. Future research should explore longitudinal impacts of sustainability interventions and comparative analyses across different urban transit systems to refine best practices in sustainable urban mobility planning.
