The overtaking maneuver performed by motorcyclists is one of the primary causes of motorcycle accidents. However, few studies in the literature deal with this topic and there are no studies modeling the total overtaking duration, i.e. the time during which extreme hazards are manifest. The present paper aims to analyze the motorcyclists' behavior during overtaking and to model the total overtaking duration. A field experiment, using instrumented motorcycles, was performed to collect data and a survival analysis was carried out to model the total overtaking duration. Twenty young motorcyclists drove their own motorcycles, which were instrumented with a camera and a global positioning system device (GPS), onto a two-lane suburban road in Rome. A total of 101 overtaking maneuvers were recorded. A methodology, based on video and GPS analyses, was developed to obtain data describing the motorcyclists' behavior. The obtained results showed that the mean values of the main parameters of the overtaking maneuver (total overtaking duration - 6.6 s - and distance - 109.7 m - lateral distance from the passed vehicle - 1.50 m) were consistent with the few data available in the revised literature. The total overtaking duration was modelled using a hazard-based duration model. The parametric accelerated failure time duration model with a log-logistic distribution, which was the best-fitted distribution, identified the covariates which affected, in a statistically significant way, the total overtaking duration. The obtained model revealed that the overtaking duration depends on several covariates. The greater average impact was found for the initial distance and speed difference, while the initial lateral distance and final distance produced a minor impact. When performing a multiple overtaking, the duration of the maneuver tended to increase by 31 %. This research can be considered as a pilot study and a starting point for future advances on motorcyclists' behavior during overtaking maneuver and for modeling the total overtaking duration. In addition, the findings of this study could contribute to the development of advanced rider assistance systems for the overtaking maneuver based on current driving conditions.
摩托车驾驶员的超越行驶是摩托车事故的主要原因之一。然而,文献中很少有研究涉及这个主题,也没有研究对总超越时间(即在极端危险显现期间的时间)进行建模。本文旨在分析摩托车驾驶员在超越行驶时的行为,并对总超越时间进行建模。使用装有仪器的摩托车进行了现场实验,以收集数据,并进行了生存分析以对总超越时间进行建模。20 名年轻的摩托车驾驶员驾驶自己的装有摄像头和全球定位系统(GPS)设备的摩托车在罗马的一条双车道郊区道路上行驶。共记录了 101 次超越行驶。开发了一种基于视频和 GPS 分析的方法,以获取描述摩托车驾驶员行为的数据。获得的结果表明,超越行驶的主要参数(总超越时间-6.6s-和距离-109.7m-超越车辆的横向距离-1.50m)的平均值与修订文献中可用的少数数据一致。使用基于危险的持续时间模型对总超越时间进行建模。对数逻辑分布的参数加速失效时间持续时间模型是最佳拟合分布,确定了以统计学方式显著影响总超越时间的协变量。所获得的模型表明,超越时间取决于几个协变量。初始距离和速度差的影响较大,而初始横向距离和最终距离的影响较小。当进行多次超越时,操作持续时间往往会增加 31%。这项研究可以被视为一项初步研究,也是未来对摩托车驾驶员在超越行驶时的行为和对总超越时间建模的研究的起点。此外,本研究的结果可能有助于基于当前驾驶条件开发用于超越行驶的先进驾驶员辅助系统。
