Description of plan：

　　Assess the risks to highway transportation system due to climate change, and establish the platform for checking by railway administration agencies.

Research result：

• Integrated the data of external unit and the MOTC cross-sector data, value-added railway/highway risk map: Complete the risk assessment in the impact to social economy when the traffic of freeway, provincial highway, expressway, Taiwan railway and high-speed railway is interrupted due to the flooding and slope hazard under the macro scenario of rainfall during the reproducing period in the future. Implemented the information platform through GIS function for the railway and highway administration agencies to check the risk levels to the subordinating facilities due to climate change.   
• Screened the hot-spot section of 200-year rainfall reproducibility under climate change in the future (15.5% for flooding section and 17.9% for slope hazard) in order to help the railway and highway administration agencies to deploy the curing manpower and relevant resources effectively.
• On November 28, 2016, we have submitted the railway and highway hot-spot related information to the competent agencies under MOTC. Based on the result of this Plan, the highway facility related improving measures were developed by Directorate General of Highways has developed. Under the approval rendered by the Executive Yuan in August 2017, the construction items were included in the “Provincial Highway Improvement Plan” for review.

Effect of the plan：

　　Support the development of next edition of National Climate Change Adaptation Plan (Traffic System).

　　Help the railway and highway administration agencies control over the risk hot spots and causes of hot spots in order that the facility improving and curing measures will be submitted in due time so as to minimize the impact of the hazard.
