项目摘要

1.The influence of studded tire usage regulation on traffic safety in winter :(1) From some analyzes of winter traffic accident characteristics due to tire type difference based property and human damage accident data in Sapporo and Hokkaido, it was shown that the proportion of skidding accidents with cars wearing studdless t13EA\ : ires was more than that of studded tires.(2) Road surface conditions and climatic characteristics in winter were considered from using actual road surface condition survey data in Hokkaido.(3) Degree of hazard of winter road using skidding resistance value was evaluated for roads in Hokkaido, and degree of hazard map was created.(4) The amount of deicing chemicals requiring for ice control was calculated.2.On the road traffic information system in winter :(1) From the results of questionnaire to drivers, it was shown that they expected the information on road traffic in consequence of studded tire regulation.(2) In order to predict road surface conditions of several points on a route, two statistical methods, that is, GMDH and network method, were applied.(3) The analytical method for prediction of road surface temperature at a hazard expecting point was studied.

1.镶钉轮胎使用规定对冬季交通安全的影响：（1）通过对札幌和北海道因轮胎类型不同而造成的冬季交通事故特征和人体伤害事故数据的分析，使用无钉t13EA\ :轮胎的汽车发生打滑事故的比例高于镶钉轮胎。（2）根据实际情况考虑冬季路面状况和气候特征。北海道路面状况调查数据。(3)使用抗滑阻力值对北海道道路的冬季道路危险程度进行评估，并制作危险程度图。(4)计算防冰所需的除冰剂用量。2.关于冬季道路交通信息系统：(1)从对驾驶员的问卷调查结果表明，他们期望通过镶钉轮胎获得道路交通信息。 (2)为了预测路线上多点的路面状况，采用了GMDH和网络法两种统计方法。(3)研究了危险预期点路面温度预测的解析方法。
