This study explored the impacts of pedestrian-crossing configurations and other design features, on accident occurrences at signalized junctions situated on central public transport routes (PTRs) of urban arterials. Statistical tests and negative-binomial regression models were applied to identify factors affecting accidents and to examine accident numbers of the PTR junctions as opposed to comparison-sites. At the PTR junctions, a consistent impact of pedestrian-crossing configurations on accidents was found, where a gradated-crossing with mixed-shifting is the least safe. Four-legged junctions tend to higher accident numbers relative to the three-legged junctions. PTR junctions are characterized by higher accident numbers, related to comparison-sites, when controlling for other design characteristics. The study findings may assist in selecting preferable design solutions while planning PTR.
本研究探讨了人行横道配置及其他设计特征对城市主干道中央公共交通路线(PTR)上信号交叉口事故发生情况的影响。运用统计检验和负二项回归模型来识别影响事故的因素,并考察PTR交叉口与对照点相比的事故数量。在PTR交叉口,发现人行横道配置对事故有一致的影响,其中混合移动的渐变式人行横道最不安全。与三岔路口相比,四岔路口往往事故数量更多。在控制其他设计特征的情况下,PTR交叉口与对照点相比事故数量较多。研究结果可能有助于在规划PTR时选择更优的设计方案。
