Title:
Variability on Travel Time Measurement Study by the Degree of Data Aggregation 
Abstract:
This study investigated the impact of different degree of data aggregation on the travel time measurement study. For this study, the travel time measurement data were obtained from the GPS-equipped probe vehicle, Bluetooth devices, and Sensys detection system. The collected travel time data were controlled at three levels reflecting the degree of data aggregation: 1) averaged the results (two data points) from the GPS-equipped probe vehicle, 2) aggregated for entire period as a low level data re...    »
