摘要: 为刻画不同降雨强度下的城市公交系统性能曲线,构建城市公交系统运行韧性测度模型,以扬州市主城区公交系统为案例,分析不同区域公交线网运行韧性以及公交线路运行韧性测度结果,并基于上述韧性测度结果进一步量化不同等级韧性下公交站点的运行状态,厘清公交网络-线路-站点运行韧性时空演变的特征。结果表明:在降雨事件中,城市公交系统在不同区域的公交线网表现出不同的性能扰动,不同区域公交系统的吸收、恢复、适应能力不同,公交运行韧性表现出明显的空间异质性,早高峰叠加强降雨事件对公交运行韧性的影响较为显著;在不同强度降雨事件下,公交线路在不同区域的运行韧性表现不同,且不同等级韧性对公交站点影响具有显著差异,尤其是在低等韧性下,公交站点可靠性下降(站时间间隔增加、站点准时度下降)。

Abstract:

To characterize the performance curve of urban bus systems under different rainfall intensities, a resilience measurement model for urban bus system operations was constructed. Taking the bus system in the main urban area of Yangzhou as a case study, the operational resilience of transit networks across different regions and individual routes were analyzed. Building upon aforementioned resilience measurement results, the operational status of bus stops under different resilience levels was further quantified. The spatio-temporal patterns of resilience evolution within the integrated "network-route-stop" hierarchy were elucidated. The results show that during rainfall events, urban bus systems exhibit varying performance disturbances across different regions. The variations in the absorption, recovery, and adaptation capacities of bus systems across different regions, significant spatial heterogeneity in resilience is observed, resulting in pronounced spatial heterogeneity in operational resilience. The combined effect of morning peak hours and extreme rain events has a notable impact on bus operational resilience. It is also found that the operational resilience of bus routes varies across different regions under rainfall events of varying intensity, and different levels of resilience lead to significant differences in the performance losses of bus stops. Notably, under low resilience conditions, the reliability of stops decreases (an increase in arrival intervals and a decrease in stop punctuality).

Key words: rainfall intensity, urban bus system, operational resilience measurement, system performance, spatio-temporal evolution
