Spatial Correlation Analysis of Truck Traffic Patterns along Road Network Using Arc-GIS: A Case Study of the Province of Saskatchewan

摘要

Truck information is one of the important inputs for better pavement analysis, design, maintenance and management. While more efforts have been directed towards development of more accurate design methods, like Mechanistic-Empirical Pavement Design Guide (MEPDG), less have been done to enhance techniques for acquiring more accurate truck traffic information. By the use of different spatial statistical and geo-statistical tools found in Arc-GIS software, this study used data from 12 WIM and 6 AVC stations to examine spatial truck traffic patterns along selected road sections in the Province of Saskatchewan.
