Car-Following Experiments Using RTK GPS and Stability Characteristics of Followers in Platoon

Ranjitkar, Prakash / Nakatsuji, Takashi / Gurusinghe, Gemunu S. / Azuta, Yoichi

Real time kinematic (RTK) GPS is featured by its outstanding accuracy in measuring position and speed dynamically. A car-following experiment was conducted using ten passenger cars each equipped with RTK GPS receivers in a test track of Hokkaido Developing Bureau, Japan. This experiment has tested various speed patterns for lead vehicle including four sinusoidal curve patterns, four constant speed patterns and a random speed pattern. The effect of change in lead vehicles' speed on the driving characteristics following drivers were measured in terms of position and speed data taken by RTK GPS receiver equipped in each vehicles. These data are analyzed to establish the effect of change in speed in terms of variation of reaction time, sensitivity factor and stability factor along the platoon for each speed patterns. Although for some of the driving patterns, the variation of these characteristics of drivers seems to have some trends but it cannot be verified statistically as in most of cases no such trends are observed.
