Evaluation Method for Traffic Operation Status on Ordinary Highway Roads

Average travel speed and density ratio are selected as the traffic state evaluation indexes. Based on the long-term analysis of the distribution characteristics of the detection data of 166 intermodulation points of 26 national and provincial highways in Chongqing, the model for calculating the point speed and travel speed during congestion is established, and the reasonable rating thresholds for identifying indicators are determined according to the grade test scores. Based on logical rules, the synthetic evaluation model that uses travel speed and density ratio as evaluation indexes is established, and the evaluation method suitable for ordinary highway operation status in China is determined. By verifying and analyzing the determination result of the actual operation status of the 26 common highways in Chongqing, the better adaptability of the model is proven.
