汽车典型公路的调查与选取

Investigation and Selection of the Vehicle Typical Road

通过对公路的分类进行分析,制定公路调查方案,建立公路数据库.采用物元分析方法,建立物元可拓的评价模型,对中国公路主枢纽城市进行典型性评价,选取出典型地区.采用德尔菲法,利用驾驶员主观感觉评价汽车在道路上的行驶质量,建立铺装类型、技术等级、道路使用年份与路面平整度之间的定性关系.利用模糊聚类和层次划分的方法对路面平整度进行划分,从而建立铺装类型、技术等级、道路使用年份与路面平整度之间的定量关系.结合道路的平整度分布情况和样本路段选取的原则,采用均匀分布随机抽样函数从公路数据库中进行抽样,从而选取出典型公路.

According to the classification of road, a road investigation plan is worked out and a database is established. This paper builds up an evaluating model of the Matter-Element extension based on the Matter-Element Analysis Method. The typicality of main hub cities of China is evaluated and the typical regions are selected. Based on the driver＇s subjective evaluation of driving quality on the road, a qualitative relationship between road surface roughness and road paving type, road level, and road using time is established by applying the Delphi Technique. The road surface roughness is sorted using the Fuzzy Clustering Method and level division method, and the quantitative relationship between road surface roughness and road paving type, road level, and road using time is established. Considering the road surface roughness distribution and typical road select principle, the typical road is selected by using uniformly distributed random sampling function from the road database.
