Abstract

Better understanding of the equity impacts of automated vehicles (AV) is needed to design equitable deployment plans for AV technology. The goal of this study was to develop and demonstrate a modeling framework to support distributional equity assessments of AV systems prior to their wide adoption. This modeling framework takes a disaggregated approach that integrates agent-based simulation, diverse transportation outcomes, and equity analyses. The framework uses individual-level data to capture detailed disparities in transportation outcomes, applies a state-of-the-art multi-agent traffic simulation model (MATSim) to simulate privately-owned and shared AVs simultaneously, and considers distributional equity from multiple perspectives. To test and demonstrate the framework, a case study was conducted for the Tampa Bay region. Five scenarios were considered with different AV market shares and integration strategies based on scenario planning by the U.S. Federal Highway Administration. Results reveal that high AV penetration rates were required for substantial reductions in inequality. The introduction of AVs led to a more even distribution of accessibility, but slightly more uneven distribution of traditional mobility and affordability. Impacts of disparities in outcomes for disadvantaged groups were mixed. These results suggest that AVs will likely perpetuate existing inequity in the transportation system as long as its fundamental structure remains the same as today. Results highlight the importance of planning and design strategies that directly address the distributional impacts to ensure that AV technology is deployed equitably.

自动驾驶汽车对分配公平的影响:分类方法
需要更好地了解自动驾驶汽车(AV)对公平的影响,以便为自动驾驶汽车技术设计公平的部署计划。本研究的目标是开发并演示一个建模框架,以支持在广泛采用自动驾驶汽车系统之前对其进行分配公平性评估。该建模框架采用了一种分类方法,将基于代理的模拟、不同的交通结果和公平分析融为一体。该框架使用个人层面的数据来捕捉交通结果中的详细差异,应用最先进的多代理交通模拟模型(MATSim)来同时模拟私人拥有和共享的自动驾驶汽车,并从多个角度考虑分配公平问题。为了测试和展示该框架,对坦帕湾地区进行了案例研究。根据美国联邦公路管理局的情景规划,考虑了五种不同的自动驾驶汽车市场份额和整合策略。研究结果表明,要大幅减少不平等现象,需要较高的自动驾驶汽车渗透率。引入自动驾驶汽车后,无障碍交通的分布更加均匀,但传统交通和可负担性的分布略显不均。对弱势群体结果差异的影响不一。这些结果表明,只要交通系统的基本结构与今天相同,那么自动驾驶汽车很可能会延续交通系统中现有的不公平现象。这些结果凸显了规划和设计策略的重要性,这些策略可以直接解决分配方面的影响,以确保公平地部署自动驾驶汽车技术。

期刊介绍: Transportation Research: Part C (TR_C) is dedicated to showcasing high-quality, scholarly research that delves into the development, applications, and implications of transportation systems and emerging technologies. Our focus lies not solely on individual technologies, but rather on their broader implications for the planning, design, operation, control, maintenance, and rehabilitation of transportation systems, services, and components. In essence, the intellectual core of the journal revolves around the transportation aspect rather than the technology itself. We actively encourage the integration of quantitative methods from diverse fields such as operations research, control systems, complex networks, computer science, and artificial intelligence. Join us in exploring the intersection of transportation systems and emerging technologies to drive innovation and progress in the field.
