备注

将静态理论模型与动态仿真模型相结合,构建公交专用道设置效益指标评价体系,分别通过数学理论模型与VisSim仿真得到设置公交专用道前后道路各项指标的变化情况.探究公交专用道设置效益的综合评价方法,提升评价结果的科学性.结果表明,当道路饱和度为0.76时,设置公交专用道具有最佳效益.理论模型的计算结果可为仿真模型的参数标定提供参考,仿真结果又可以与理论模型计算结果进行对比分析,验证理论模型的有效性,保证最终效益评价结果准确.探究路段设置公交专用道所对应的最佳饱和度等临界条件,为公交专用道的设置提供理论参考.该方法可用于提升公交专用道效益评价的可靠性和鲁棒性,并为提高仿真建模精确度提供参考.
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.
