As the development of intelligent transportation technology, accurately estimating the driving maneuver transition in the connected vehicle (CV) environment is crucial to design driver assistance systems. In this study driving data were collected using a driving simulator. Thirty-six test subjects participated in the experiment and the length of the road is about 20km. In the experiment, the test vehicle can be divided into two types: equipped with a driver assistance system and not equipped with a driver assistance system. Driving behavior in this study was categorized into 9 maneuver states. This paper divided the experimental road into nine zones. A comparative analysis was also conducted to examine the changes in speed performance and driving maneuver transition between in connected vehicle (CV) environment and traditional vehicle (TV) environment. The experimental using maneuver transition probabilities to represent the driving behavior. The results shows that connected vehicle can help drivers to adjust vehicle speed to ensure driving safety and comfort.
