摘要
Abstract
It is difficult to gain density parameter which can be used in traffic flow model, thus occupan-cy-flow model is more practical. The article proposed the conception of analytical unit of occupancy, ana-lyzed the influence mechanism of large vehicle based on different car-following combination considering the probability of analytical unit of occupancy, concluded that original occupancy could not reflect the im-pact of large vehicle on traffic flow and occupancy-flow model. Then the article modified occupancy based on vehicle headway and mixed rate of large vehicle, established occupancy-flow model in mixed traffic flow situation. Data collected from Beijing expressway showed the model in the article was effective and more meaningful.关键词
