Lifecycle cost and resilience performance evaluation of climate-resilient urban road infrastructure under climate risk scenarios

Aim: Urban road infrastructure is increasingly exposed to climate-induced hazards such as flooding, extreme heat, and intense precipitation. These hazards disrupt mobility, increase maintenance costs, and threaten economic stability. This study evaluates the lifecycle cost and resilience performance of climate-resilient urban road infrastructure under climate risk scenarios. Methodology: Ahybrid framework integrating Lifecycle Cost Analysis (LCCA) and resilience performance modeling is developed. Two scenarios, conventional road infrastructure and climate-resilient road systems, are assessed over a 50-year lifecycle using Net Present Value (NPV) modeling. Results: Results indicate that climate-resilient infrastructure increases initial capital costs by 12–18% but reduces lifecycle costs by up to 25% due to lower failure rates and faster recovery after disruptions. Conclusion: Climate-resilient road infrastructure is economically viable when evaluated over the long term. Integrating resilience into infrastructure planning improves system reliability and reduces climate-related risks.
