Abstract: Climate abnormally has significant impact on each period of transportation systems, from line surveying, designing, construction and operation. So, itis of momentous significance to make thorough investigations and studies on theimpact mechanism of climate abnormally on transportation systems and put out perfect proposal to mitigate the impacts. Due to the different meteorological and geographical condition in each area, theresponse of each transport to abnormal climate is different. It is necessary toestablish a set of analysis and assessment system of forecasting, defense or reducing of abnormal climate. The system includes three parts: a] the forecasting model of possible burst of climate disaster; b] the judging model of order of climate disaster seventy; and c] the analysis model of transportation system safety. According to this system, the impact of abnormal climate on transport is to be overall given. In order to reduce the impact of abnormal climate, the establishment of unified system to coordinate and manage is suggested. The system contains six parts: a] the command system of transport defending climate disaster, hi the forecasting system of abnormal climate, c] the construction system of transport infrastructure, d] the rescuing and mediating system of disaster or accident, e] the insurance system of providing disaster relief, and f] the database of transport defending and reducing climate disaster. In view of different transport, the countermeasures on people, transport means and line environment to improve the ability of defending and reducing abnormal climate are respectively suggested.
