混合交通的熵特性与交通组成性能

Entropy and Component Properties of Mixed Traffic

Based on the theoretical research and field observation, this paper proposes to use entropy to express the component properties in the mixed traffic. The practical formula for calculating the traffic entropy is obtained. Through the regression analysis of the data obtained from 35 sections of arterial highways, we find that there exists better correlation among the traffic volume, the mean speed and the traffic entropy. The application of the traffic entropy to evaluating and dealing with practical problems in the mixed traffic is obviously comparable, practical and effective.
