Abstract: Presently, Global Positioning System (GPS) receiver is a very popular tool to track the movement of an object and obtain its associated information in real-time. It has been commonly used in various fields including transportation. In this research,the highly sampled rate GPS of 5 Hertz is utilized to track realtime movement of public buses in Bangkok. By extracting and analyzing the GPS data record, it can provide more meaningful information on the operations of public bus services. The aim of this study is to evaluate the movement of public bus by comparing among different recording intervals; i.e., 0.4, 0.6, 0.8, 1, 2, 3, 4 and 5-s in order to see the effects of sampling rate on the trajectories. The results show that the high sampling rate of less than 1s tends to provide a discrete fluctuation rather than continuous trajectory of the real movement. A sampling rate of 1- 2s seems to be appropriate with respect to the reasonable instantaneous speed and acceleration value
