Analysis of Transverse Traffic Distribution of Taxiways

The project, "Pavement Monitoring and Analysis for Chiang Kai-Shek (CKS) International Airport", is the first large-scale monitoring project on airport pavement in Taiwan and a growing research area in pavement management systems. This paper analyzes the monitoring data of positioning gauges of nose gear for this project. Positioning gauges are used to collect large amounts of aircraft positioning data on the taxiway at CKS Airport. Additionally, the paper investigates the taxiing patterns on the taxiway at CKS Airport to establish the basis for slab fatigue analysis of long-term repetitive loadings. The authors combined the FAMOS and EXCEL programs to develop the analyzing procedure of the nose gear position. Analysis of much aircraft taxiing data revealed that aircraft taxiing patterns follow the normal distribution with 50.4 centimeters as standard deviation. However, compared with narrow-body aircraft, taxiing behavior of wide-body aircraft is more diversified and slightly shifts to the left of centerline.
