Abstract

This paper aimed at utilizing GIS software in calculating pavement condition index )PCI( values, using four different interpolation methods: IDW, spline, trend and kriging. The case study covers four major streets in Nablus city with a total length of about 6.50 km. The PCI values were calculated using the ASTM conventional method. The four streets were divided into equal 100- meter sections. The PCI values were also calculated for each point of defect in both directions of the streets. The results of the four methods (point by point of defects) were compared manually with the conventional method (ASTM procedure). The results showed that the spline method had a strong correlation with the conventional method in terms of multiple R and R-square calculation (multiple R for left 0.918, right 0.947 and R2 for left 0.843, right 0.897). This method also fitted the data better than the other methods, as seen from the linear regression model results, in addition to producing the minimum error value. The results indicated that by identifying the PCI value, it would be possible to select the proper pavement maintenance and corresponding cost for each point of defect. This in turn would help in prioritizing pavement sections. KEYWORDS: Pavement condition index (PCI), GIS, Interpolation, Distress, Maintenance, Spline.

利用ArcMap GIS评估现有路面病害——以纳布卢斯市为例

本文旨在利用GIS软件计算路面状况指数PCI（值），采用IDW、样条曲线、趋势和克里格四种不同的插值方法。PCI值使用ASTM常规方法计算。这四条街道被分成100米长的路段。还计算了街道两个方向上每个缺陷点的PCI值。手动将四种方法（逐点缺陷）的结果与传统方法（ASTM程序）进行比较。结果表明，样条法在倍数R和R平方计算方面与传统方法有很强的相关性（左倍数R 0.918，右倍数R 0.947，左倍数R2 0.843，右倍数R2 0.897）。从线性回归模型结果来看，该方法除了产生最小误差值外，还比其他方法更好地拟合数据。结果表明，通过识别PCI值，可以为每个缺陷点选择合适的路面维护和相应的成本。这反过来将有助于优先考虑路面路段。关键词：路面状况指数（PCI），GIS，插值，病害，养护，样条曲线。
