Carpooling consists of drivers and passengers sharing a journey and its costs. Nowadays, in the context of mobility as a service, organized carpooling encompasses a service and trust relationship between drivers and passengers, by matching common routes and splitting cost through mobile phone applications. Therefore, passengers expect a certain level of travel quality and safety. In this context, this research aims to verify the hypothesis that drivers in an organized carpooling situation (CP) show safer driving behavior in terms of speeding (SP) and mobile phone use while driving (MPU) in comparison with non-carpooling (NCP) drivers. The research is based on data from the Brazilian Naturalistic Driving Study (NDS-BR) conducted in the City of Curitiba, with 40.45 driving hours and a traveled distance of 895.87 km. Methodology included the selection of safety performance indicators on SP and MPU, use of nonparametric Wilcoxon signed rank test for safety performance indicator comparisons and Pearson Chi-Square to test the association between CP or NCP and low or high indicator values. Hypothesis test results point in the same direction and partially confirm the initial assumption that CP induces safer behavior in terms of speeding. The statistically sound results showed that CP drivers engaged in less speeding episodes and mobile phone use duration in comparison to NCP drivers, as well as lower speed while using a mobile phone. In addition, driver behavior in CP and NCP situations also differed in terms of the type of MPU, with the proportion of types of use that demand a higher level of visual and manual distraction being higher among NCP drivers. In summary, these results confirm the initial hypothesis of safer driving behavior during carpooling in terms of MPU while driving.
拼车是指司机和乘客共同分担行程及其费用。如今，在出行即服务的背景下，有组织的拼车包括司机和乘客之间通过手机应用程序匹配共同路线和分担成本而建立的服务和信任关系。因此，乘客期望一定的出行质量和安全水平。在此背景下，本研究旨在验证以下假设，即在有组织的拼车环境（CP）中，与非拼车（NCP）司机相比，司机在超速（SP）和驾驶时使用手机（MPU）方面表现出更安全的驾驶行为。该研究基于巴西自然驾驶研究（NDS-BR）的数据，该研究在库里蒂巴市进行，包括 40.45 小时的驾驶时间和 895.87 公里的行驶里程。方法包括选择 SP 和 MPU 的安全性能指标，使用非参数 Wilcoxon 符号秩检验进行安全性能指标比较，以及使用 Pearson Chi-Square 检验 CP 或 NCP 与低或高指标值之间的关联。假设检验结果指向同一方向，部分证实了最初的假设，即 CP 在超速方面诱导更安全的行为。具有统计学意义的结果表明，与 NCP 司机相比，CP 司机超速和使用手机的时间更少，使用手机时的速度也更低。此外，CP 和 NCP 情况下的司机行为在 MPU 类型方面也存在差异，NCP 司机使用手机时需要更高水平的视觉和手动分心的使用类型比例更高。总之，这些结果证实了最初的假设，即在驾驶时使用手机方面，拼车时的驾驶行为更安全。
