Abstract:	By applying the concept of information entropy in the information theory, this study aims to create a complexity index to measure the driver-perceived driving environment and to give remedy for the past indexesâ incapability of showing driversâ perceived comfort and safety. The complexity index is calculated by the driversâ driving behaviors of speed, acceleration and deceleration, and horizontal shift area. We show that the complexity index is a proper qualitative index to truly reflect the driversâ perception of driving environment and to measure the level of service. It can be a supplement index for the traditional traffic measures.
