Study on Evaluation Index System of Traffic Simulation under the Concept of Low-Carbon
Evaluation index system of traffic simulation is very important to compare the difference of several cases, which contributes to the advance of traffic simulation models and technologies. Under the concept of low-carbon, the paper establishes evaluation index system of traffic simulation. Firstly, the paper analyzes the requirements of the evaluation index system of traffic simulation from two aspects which are the application characteristics and the application under the concept of low-carbon of traffic simulation models and technologies. On the basis of analysis above, it establishes the evaluation index system of traffic simulation which concludes road network structure index, traffic operation state index, traffic environment index and traffic safety index. It proposes the application rules of evaluation index system. Then, it proposes the two-level combined evaluation method for calculating weights on the basis of comparative analysis about two methods, which are the analytic hierarchy process (AHP) method and entropy method. Finally, it applies the proposed evaluation system to calculate the comprehensive index values of two transit operation cases of Beijing Olympic Games Opening Ceremony audience evacuation. It is shown that evaluation index system of traffic simulation is practicable and effective.
