Abstract

The imbalance between traffic volume growth and road infrastructure capacity has intensified congestion, reduced logistics efficiency, and increased emissions along urban and intercity transport corridors. This study evaluates the technical and engineering-economic feasibility of the proposed 15.5 km Section X Toll Road using the Life Cycle Cost (LCC) approach. An empirical quantitative method was employed by integrating road capacity analysis, geometric design, rigid pavement design, and investment evaluation using Net Present Value (NPV), Internal Rate of Return (IRR), Benefit–Cost Ratio (BCR), and Payback Period (PP) indicators. The results indicate that the proposed toll road reduces the degree of saturation of the existing arterial road from 0.85 to 0.42. Economic evaluation produced a positive NPV of IDR 542 billion, an IRR of 12.45%, a BCR of 1.18, and a payback period of 14 years and 3 months. Sensitivity analysis confirms that the project remains financially feasible under a 15% increase in construction costs and a 10% decline in toll revenue. These findings demonstrate that the Section X Toll Road is technically feasible, economically viable, and capable of supporting sustainable infrastructure investment.

Abstract

Urban flooding represents a systemic risk emerging from the interaction between hydrological hazards, spatial transformation, and infrastructure vulnerability, demanding a management paradigm that transcends conventional engineering responses. This study develops a non-empirical conceptual framework for optimizing risk-based infrastructure management to strengthen urban flood resilience. The framework integrates infrastructure asset lifecycle management, disaster risk theory, and urban governance into a multilayer analytical model that explains causal relations among planning, implementation, maintenance, and adaptive capacity. A systematic literature synthesis and thematic-critical analysis were employed to construct stable conceptual propositions and evaluate internal coherence across disciplines. Findings indicate that preventive planning, adaptive asset management, institutional coordination, and participatory monitoring operate as interdependent mechanisms that reduce system fragility and enhance operational learning. The proposed model provides an analytical structure for evaluating infrastructure effectiveness without dependence on a single empirical context while preserving methodological rigor. This study contributes theoretically by linking risk governance with lifecycle infrastructure management and methodologically by offering a replicable conceptual synthesis for resilient urban systems.
