China Abstract: By combing the static theoretical model with the dynamic simulation model, we develop a benefit index evaluation method for bus lane setting. By using mathematical theoretical model and simulation software VisSim, we obtain the changes of indexes under the conditions of whether or not to set the bus lane to investigate the comprehensive evaluation method of the benefits of bus lane setting and to improve the accuracy of the evaluation results. The evaluation results show that the bus lane has the best benefit when the road saturation is 0.76. It is confirmed that while the results of mathematical theoretical model can provide references for the simulation model during parameter setting, the simulation results can make a comparative analysis with the mathematical results as well to verify the validity of theoretical model and to ensure the accuracy of the final benefit evaluation result. This research explores the critical conditions such as optimal saturation, and provides a theoretical reference of bus lane setting. This method improves the reliability and robustness of benefit evaluation of bus lane setting and provides a reference for improving the accuracy of simulation modeling.
