A novel model to evaluate urban overall traffic condition

Urban transportation is very important for economy development of a city, and accurate and effective overall traffic status in an area provides the basis for transportation application service. This paper proposes a novel model-OTCEM, evaluating urban overall traffic condition effectively. In this model, a regional transport evaluation index is developed. Through the model, the trends of normal transport are obtained. Meanwhile, in this paper, based on different impact factors, those abnormal data are analyzed and the impact assessments are completed. At last, the model is validated through the truth traffic data of Beijing, experimental results show that with this model, we can get effective evaluation of the overall urban transportation status.
