Transportation networks in Lagos face severe climate threats, notably rising sea levels that damage coastal roads and bridges, heavy rainfall causing inland flooding, frequent storms disrupting connectivity, and fluctuating temperatures compromising road surfaces. To address these vulnerabilities, ten adaptation strategies offer pathways towards greater resilience. Practical interventions include the installation of robust drainage systems and slope stabilisation measures to protect vulnerable routes. Collaborative measures highlight partnerships with private sector organisations to foster sustainable practices and advance green transport initiatives. These solutions underpin proposed policy frameworks designed to deliver clear regulatory guidelines for integrating resilience into urban transport infrastructure. Successful deployment relies on comprehensive stakeholder engagement and public consultation, fostering collective responsibility to ensure municipal transit systems withstand extreme weather, structural failures, and related operational disruptions.
Urban transport networks are crucial for daily mobility and economic activity, yet climate change increasingly threatens their reliability. By addressing vulnerabilities such as flooding and surface deterioration, structured adaptation strategies help prevent costly travel disruptions, safeguard vital public assets, and build urban environments capable of quickly recovering from environmental shocks.
The findings outline early-stage policy and strategic frameworks rather than commercial products. Potential applications relate to municipal planning frameworks, public sector infrastructure guidelines, and public-private partnership models for green transit. The work appears at an early stage of adoption, requiring city authorities and civil engineering contractors to convert the suggested policies and structural measures into technical specifications and live public works programmes.

This study aims to explore innovative adaptation strategies that can effectively mitigate the climate threats faced by transportation infrastructure in Lagos, Nigeria. The study highlights the urgent need for innovative approaches to address the challenges posed by climate change to transportation systems. By analyzing the current vulnerabilities and potential impacts of climate change on transportation infrastructure, the authors identify and propose four current challenges facing transportation infrastructure as a result of climate change. These threats include the impact of rising sea levels on coastal roads and bridges, the vulnerability of inland transportation systems to extreme weather events such as floods and heavy rainfall, the potential disruption of transportation networks as storms become more frequent and intense, and the implications of temperature changes on road surfaces and their structural integrity. The study also identified and proposed ten potential adaptation measures that can enhance the resilience of transportation systems in Lagos, Nigeria. The adaptive measures ranged from increasing the resilience of road networks through the implementation of proper drainage systems and slope stabilization measures to forming partnerships with private sector companies to promote sustainable practices and the development of green transportation initiatives. To facilitate these adaptive measures, the authors used them to develop various policy frameworks for transportation resilience in Lagos, Nigeria. These policy frameworks aimed to provide guidelines and regulations for the implementation of adaptive measures, ensuring their effective integration into the transportation system. The authors emphasized the importance of stakeholder engagement and public participation in decision-making processes to foster a sense of ownership and collective responsibility towards building resilient transportation systems. By adapting to these measures, Lagos, Nigeria, can enhance its ability to withstand and recover from transportation disruptions caused by various hazards, such as extreme weather events, infrastructure failures, or security threats.
