ABSTRACT

Although several studies have attempted to determine the mileage and time inefficiency of ridesourcing services due to concerns about traffic and environmental impacts of these services, all of them provide a point estimate, which does not reflect the uncertainties in the calculation of these estimates. As such this study aims to present the efficiencies as ranges, based on lower and upper limits by identifying drivers' daily activity schedule. Based on an analysis of 200 busiest RideAustin drivers’ trips data (around 282,037 trips over a 6 months period from 1 October 2016) the study finds that the mileage efficiency ranges from 44.3% to 71.6%, while time efficiency ranges from 42.8% to 58.4%. This means that for every 100-miles of a fare-payer passenger, drivers must travel an additional 40 to 126 miles empty. The heterogeneity of the efficiency at the driver level and the efficiency in the temporal dimension were also considered.

摘要

尽管由于担心这些服务的交通和环境影响，一些研究试图确定乘车服务的里程和时间效率低下，但它们都提供了一个点估计，这并没有反映这些估计计算中的不确定性。因此，本研究旨在通过确定驾驶员的日常活动时间表，根据上下限将效率呈现为范围。根据对 200 位最繁忙的 RideAustin 司机出行数据（从 2016 年 10 月 1 日起的 6 个月内约 282,037 次出行）的分析，该研究发现里程效率从 44.3% 到 71.6%，而时间效率从 42.8% 到 58.4 %。这意味着每 100 英里的付费乘客，司机必须额外空车 40 到 126 英里。
