Support system for snow disaster-mitigation in urban area considering transition of social environment

研究结果总结如下：(1)调查了雪灾造成的生活环境障碍的实际情况，探讨了如何减少雪灾。(2)区域积雪风险评价应以灾害顺序为重点进行研究。构建了考虑积雪漂移不确定性的风险评估方法，并将评估结果与实际雪损数据进行了比较。(3)将神经网络计算技术应用于积雪深度预测，预测结果与实测资料吻合较好。(4)为了考虑老年社会环境和城市规划，研究了与生活方式结构变化相关的基础设施重排问题。(5)考虑到未来的老龄化社会，分析了地方政府的雪灾减灾政策还是民众的共识。(6)我们调查了房屋前面的屋顶和街道上除雪的实际情况。(7)从气象、地理和社会环境的角度，对雪区地震减灾进行了探讨。

The results obtained in the study are summarized as follows :(1) We investigated the actual conditions of life environmental obstacles caused by torrential snow drift, and discussed how to reduce snow disasters.(2) A study of regional snow risk evaluation should be done with an emphasis on the sequence of disaster. We constructed a risk evaluation method considering uncertainly of snow drift, and compared the evaluation results with the actual snow damage data.(3) We applied the Neural Computing technique to the prediction of the depth of snow deposit, and the predicted results were in a good agreement with the observed data.(4) In order to consider social environment and urban planning in the aged, the rearrangment of infrastructure concerning the change of lifestyle structure was investigated.(5) The policy of snow disaster reduction by the local city's government or the agreement of the people was analyzed considering the aging society in future.(6) We investigated the actual conditions of snow removal on the roof or in the street at the front of the house.(7) From the viewpoint of meteorological, geographical and social environment, mitigation of disaster in an earthquake in snow area was also discussed.
