该研究的主要目的是确定影响城市街道中街区自行车道中电动自行车、电动踏板车和自行车骑手舒适度感知的因素，并估计混合两轮交通的中街区自行车道的自行车服务水平（BLOS）。数据收集于中国南京地区三十条不同街道的三十个地点。皮尔逊卡方检验是为了比较不同骑行者群体的舒适感。显着影响骑车者舒适感的因素包括骑车者的年龄、两轮车的类型、两轮车的数量、中段自行车道的宽度、电动自行车和电动滑板车在两轮车中的比例、机动车道、自行车道和人行道之间的物理分隔、自行车道的坡度、路边出入口和路边土地利用。开发有序概率模型是为了定量评估不同影响因素对电动自行车、电动踏板车和自行车骑手舒适感的影响。结果显示，与自行车骑行者相比，电动自行车和电动滑板车的骑行者更容易感觉到舒适度较差。骑车者的舒适感随着中段自行车道宽度的增加而增加，而随着两轮车数量的增加而减少。两轮车辆中电动自行车和电动滑板车的比例对骑行者的舒适感产生了负面影响。此外，机动车道、自行车道和人行道之间的物理隔离显着增加了骑自行车者的舒适感。通过舒适感知模型，开发了一个程序并获得了见解，以帮助交通专业人员估计混合两轮交通的中街区自行车道的 BLOS。 (C) 2017 Elsevier Ltd. 保留所有权利。
The primary objective of the study was to identify the factors that influenced the comfort perception of e-bike, e-scooter and bicycle riders in mid-block bicycle lanes on urban streets and to estimate the bicycle level of service (BLOS) of a mid-block bicycle lane with mixed two-wheeled traffic. Data were collected at thirty locations on thirty different streets in Nanjing area in China. Pearson's Chi-square tests were conducted to make comparisons of the comfort perception among different cyclist groups. The factors that significantly affected the comfort perception of the cyclists included the age of the cyclists, the type of two-wheeled vehicles, the volume of two-wheeled vehicles, the width of mid-block bicycle lanes, the proportions of e-bikes and e-scooters in two-wheeled vehicles, the physical separation between motorized, bicycle and pedestrian lanes, the slope of bicycle lanes, the roadside access points and the roadside land use. Ordered probit models were developed to quantitatively evaluate the impacts of different contributing factors on the comfort perception of the riders of e-bikes, e-scooters and bicycles. The results showed that compared to the riders of bicycles, the riders of e-bikes and e-scooters were more likely to perceive a poor comfort level. The comfort perception of the cyclists increased with an increase in the width of the mid-block bicycle lane, whereas it decreased with an increase in the volume of two-wheeled vehicles. The proportions of e-bikes and e-scooters in two wheeled vehicles negatively affected the comfort perception of the cyclists. In addition, the presence of physical separation between the motorized, bicycle and pedestrian lanes significantly increased the comfort perception of the cyclists. With the comfort perception models, a procedure was developed and insights were gained to help transportation professionals estimate the BLOS of a mid-block bicycle lane with mixed two-wheeled traffic.
