Abstract

9 Dependence on private cars has led to numerous problems, where AVs could be a potential 10 solution. Pooled service, however, could be a much bigger step towards sustainable transportation. 11 This paper presents a modal shift analysis emphasizing socio-economic, travel characteristics and 12 their interaction for a sample of private car users in Tehran. A stated preference survey was 13 designed in 2021 exclusively for the research purposes, and 491 valid questionnaires were 14 gathered. One of the main contributions is considering the impact of the number of persons in 15 shared autonomous vehicle with pooled service (SAVWPS). Estimation results of discrete choice 16 model reveal that, high-income respondents, owning a personal car and being a man decrease the 17 likelihood of modal shift to SAVWPS. A negative impact is also observed for travel time, travel 18 cost, waiting time and number of persons in SAVWPS. A significant systematic heterogeneity is 19 observed in the interaction effect of travel time and dissatisfied respondents with internet taxis due 20 to the pandemic. Considering this taste variation, a lower travel time in SAVs could increase the 21 modal shift likelihood among these travelers. The findings could help transportation decision-22 makers identify the factors affecting modal shift to SAVWPS to achieve a more sustainable 23 transportation system.

共享自动驾驶汽车与集合服务，一种模式转换方法

9 对私家车的依赖导致了许多问题，而自动驾驶汽车可能是一个潜在的解决方案。然而，合乘服务可以在实现可持续交通方面迈出更大的一步。11 本文针对德黑兰的私家车用户样本进行了模式转换分析，强调了社会经济、出行特征及其相互影响。2021 年专门为研究目的设计了一项陈述偏好调查，共收集到 491 份有效问卷 14。研究的主要贡献之一是考虑了共享自主车辆集合服务（SAVWPS）人数的影响。离散选择模型 16 的估计结果表明，高收入受访者、拥有私家车和男性会降低 17 使用共享自动驾驶汽车的可能性。此外，旅行时间、旅行成本、等待时间和小规模自愿工作场所的人数也会产生负面影响。在出行时间与受访者因大流行病而对网络出租车不满意的交互效应中，19 观察到了明显的系统异质性。考虑到这种口味差异，在小型自动售票机上花费较少的旅行时间可以增加 21 这些旅行者转变出行方式的可能性。研究结果可帮助交通决策者22 找出影响乘客向小型自动客货车转移的因素，以实现更可持续的交通系统23。

期刊介绍： The objectives of Scientia Iranica are two-fold. The first is to provide a forum for the presentation of original works by scientists and engineers from around the world. The second is to open an effective channel to enhance the level of communication between scientists and engineers and the exchange of state-of-the-art research and ideas. The scope of the journal is broad and multidisciplinary in technical sciences and engineering. It encompasses theoretical and experimental research. Specific areas include but not limited to chemistry, chemical engineering, civil engineering, control and computer engineering, electrical engineering, material, manufacturing and industrial management, mathematics, mechanical engineering, nuclear engineering, petroleum engineering, physics, nanotechnology.
