Project Overview
       The highway system is the transportation subsystem with the most direct impact on people's daily lives. However, in light of climate change and adaptation, Taiwan's highway system planning mechanism and relevant regulations are insufficient. The ability to deal with extreme events in the future can be improved if the concept of climate change and adaptation is incorporated into highway planning. Engineering planning and subsequent care and management regarding the lifecycle of highway facilities should be discussed during the planning phase (including new constructions
and reconstructions) in order to increase the highway system's adaptability to the climate change environment. Therefore, the plan has completed the "Highway System in Response to Climate Change and Adaptation Guide," which will help dedicated competent authorities within
the highway system and practitioners incorporate climate change and adaptation concepts more comprehensively and systematically during the planning stage. This will facilitate further discussions of relevant norms and operating procedures, thereby improving Taiwan's
adaptive capability under climate change and constructing a climatic resilient highway system.
 Research Results

1. IPCC AR6 Working Group I Report (2021), Working Group II Report (2022), ISO14090 Governing Principles for Climate Change, ISO14091 Guidelines for Climate Change Risk Assessment, and International Transportation Adaptation Promotion have all been completed, as the collection and analysis of foreign transportation system adaptation development trends. Subordinate agencies (institutions) use them as references and for applications.
2.  As relevant references, practices for strengthening adaptive capability during the foreign highway system planning stage have been collected. Adaptation recommendations during the domestic highway system planning stage, as well as mechanisms for integrating cross-transportation system strengthening adaptation interfaces have been formulated. Practices for improving adaptive capability during the planning stage of a highway system have been completed.
3. Guidelines for highway system adaptation in response to climate change have been completed, and they can be used as a reference and for application by highway system competent authorities in order to improve highway system resilience and mitigate climate change harm.

Result Promotion and Benefits

• The dissertation paper "A preliminary study on adaptive capability methods during the highway system planning stage" was published in the "Chinese Institute of Transportation 2022 Annual Conference and International Seminar on Dissertation Papers" (December 1 and December 2, 2022).
• Two educational training sessions on climate change adaptat ion related professional knowledge have been completed: "Sharing of Climate Change Adaptation Information and Formulation of Action Plan for Adaptation" (May 26, 2022) and "Transportation System in Response to the Development Trend of Climate Change Adaptation and Practices for Strengthening Adaptative Capacity of Highway System" (September 15, 2022). In conjunction with the new phase of the National Adaptation Action Plan, the auxiliary transportation facility management agency (institution) develops relevant adaptation action plans and strengthens its grasp of the spirit of the transportation system's adaptation to climate change, further applying adaptation knowledge in adaptative business promotions; according to a satisfaction survey, educational training satisfaction is 100% and 93%, respectively.
•  A seminar on "Highway Planning and Adaptative Capability Guide (October 13, 2022)" was held with experts and scholars. Experts and scholars were invited to collaborate on the architecture and content of the adaptation guide. Domestic practical case operations and explanations were also provided in the hopes of assisting and guiding agencies in developing a deeper adaptive understanding, which will aid in the implementation and application of subsequent adaptation work.
