This paper aims to numerically evaluate acceleration behavior when vehicle starts to move in cooperate with the preceding vehicle. Since a microscopic disturbance of vehicle movement may affect macroscopic behavior of traffic flow in terms of emission, environment and safety, the authors firstly attempt to observe and analyze actual phenomenon of accelerating behavior through a test-track field data collection. Based on the fact that the accelerating behavior varied widely, the authors then assumed three representative types of ordinal, steep and moderate accelerations to extensively simulate general acceleration behavior using a car-following model. The acceleration behavior among three types of acceleration was compared in terms of acceleration rate, velocity and distance with preceding vehicles. The statistical comparison such as T-test and F-test showed that moderate and steep accelerations have a significant difference in acceleration rate and distance. This large difference in microscopic level of vehicle movement is believed to affect a large impact in a macroscopic system of traffic flow.
