摘要：AbstractWith their unique features, the bicycles exhibit chaotic and erratic trajectories in the kinetic process. It is suggested that this motion performs certain actions that can be represented as if they would be subject to perceptual process. Then demonstrate a new paradigm for the perceptual process could be interpreted as a chain psychological - physical process, which has illustrated a perceptual/behavioral/motorial approach to animating the bicyclist autonomously. Furthermore, the perception subsystem, which comprises a set of virtual online sensors, sensor data packet, and a perceptual focusers, obtains basic information about the ambient dynamic environment. The behavioral choice, situated between the sensory perception system and action system, is the most important part to respond to changes in the traffic environment. This system is used to weigh the pros and cons of the various acts and making decision through brain information processing. In addition, the action system is the basis for the rider to achieve a variety of behavioral function. Following part, this study extracts the bicycle/rider unit as fundamental element. During the kinetic process, individual visual perception plays particularly importance role. Hence, it is necessary to modeling the sight ranges dependent on velocity. Considering the movement of bicycle is anisotropic, tow smaller speed-dependent domains named reactive range and perceptive range, are proposed. The former indicates that individual may take actions to avoid potential collisions with obstacles invaded in its reactive range; while, the latter represents the obstacles could be felt within this range. Using this approach, it is possible to produce animations of bicycle/rider unit demonstrating a variety of behaviors.
