Abstract:
To accurately capture the measurement of bus reliability and evaluate whether the transit system is properly operated, an evaluation framework is established to assess the reliability of the transit system from different stratifications, including stops, routes and network levels. The bus operation data of the Hefei city is analyzed as a case study. Comparison is conducted to show the improvement made by using the advanced method, and an example of adding exclusive bus lanes to the existing bus route is provided. The proposed advanced method can avoid the shortcomings of the traditional method. For example, the value of the reliability using the traditional coefficient of variation(CV)is not between 0 and 1, and the value of reliability can decrease with the increase in the transit headway, etc. The case study shows that the advanced method can represent the real operation condition of the transit system and can be used to evaluate the transit headway reliability more reasonably.
为了准确描述公交车辆运行可靠性、合理评价公共交通系统运营状况, 提出了一种针对站点、线路、路网不同层面的公交可靠性改进计算方法.结合合肥市的公交实际运营数据, 验证了所提出的可靠性定义对于传统方法的改进效果, 并应用该方法分析了设置公交专用道后公交车辆运营可靠性的提升效果.研究表明, 所提出的改进方法, 可以克服传统可靠性评价方法的不足之处, 例如间隔可靠性评价值会出现小于0和大于1的情况, 且随着发车间隔的增大, 计算的可靠性指标值呈现减小的趋势等.该方法可以更真实地反映公交系统运营状态, 提高了公交车辆运行可靠性评价的合理性.
