This Excellence in Research will promote social equality and improve transportation accessibility for millions of transportation-disadvantaged (TD) Americans by supporting fundamental research on a novel Interoperable Transportation Service Roaming (ITS-R) System. This ITS-R system enables independent mobility service providers to willingly share their vehicle fleets and demand information in order to reduce their operational costs and improve service quality for their riders. A diverse research team consisting of researchers from two HBCUs (Florida A&M University and Morgan State University) will conduct various research tasks ranging from service optimization to travel behavior modeling. Research findings will also be integrated into undergraduate and graduate courses taught at Florida A&M and Morgan State. Online education games adapted from the research tasks will be developed to motivate K-12 students to pursue engineering degrees. The collaboration with a transportation software company will also provide internship opportunities for the students to further attract them to pursue their careers in the transportation industry.The central research hypothesis is that inter-type and inter-provider barriers in TD mobility services can be mitigated through coordinated decision-making at the organizational (service provider) and individual (rider) levels. To test the hypothesis, five specific research tasks will be conducted, as follows: (1) To design a set of mechanisms for independent paratransit service providers to willingly share demand information and vehicle fleets, and for individual TD riders to shift their travel plans when appropriate external incentives are given; (2) To develop and test new vehicle routing and scheduling algorithms that account for demand exchange, fleet sharing, and availability of inclusive autonomous vehicles (IAVs); (3) To evaluate the implications of fleet automation on paratransit operations and design optimization algorithms for allocating and operating IAVs; (4) To understand and model the organizational (service provider) and individual (rider) behaviors when the ITS-R system is operational; and (5) To integrate various system modules and demonstrate the effectiveness of ITS-R through computational experiments based on real-world data. The successful completion of those research tasks would yield a set of new mechanisms, optimization methods, and behavioral findings that are critical for TD population groups to benefit from the ITS-R system. The research findings will also inform paratransit regulatory agencies in making effective financial and operational policies.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项卓越研究将通过支持新型可互操作运输服务漫游 (ITS-R) 系统的基础研究，促进社会平等，并改善数百万交通弱势 (TD) 美国人的交通可达性。该 ITS-R 系统使独立移动服务提供商能够自愿共享其车队和需求信息，以降低运营成本并提高乘客的服务质量。由来自两个 HBCU（佛罗里达农工大学和摩根州立大学）的研究人员组成的多元化研究团队将开展从服务优化到出行行为建模等各种研究任务。研究成果还将被纳入佛罗里达农工大学和摩根州立大学教授的本科生和研究生课程中。 将开发根据研究任务改编的在线教育游戏，以激励 K-12 学生攻读工程学位。与交通软件公司的合作还将为学生提供实习机会，进一步吸引他们在交通行业追求自己的职业生涯。中心研究假设是，TD移动服务中的跨类型和跨提供商障碍可以通过以下方式缓解：在组织（服务提供商）和个人（骑手）层面协调决策。为了检验这一假设，将进行以下五项具体研究任务：（1）设计一套机制，让独立辅助公交服务提供商自愿共享需求信息和车队，并让个人TD乘客在特定情况下改变出行计划。给予适当的外部激励； (2) 开发和测试新的车辆路径和调度算法，以考虑需求交换、车队共享和包容性自动驾驶车辆 (IAV) 的可用性； (3) 评估车队自动化对辅助公交运营的影响，并设计分配和运营 IAV 的优化算法； (4) 理解ITS-R系统运行时组织（服务提供商）和个人（乘客）的行为并对其进行建模； (5) 集成各种系统模块，并通过基于真实数据的计算实验来证明ITS-R的有效性。这些研究任务的成功完成将产生一套新的机制、优化方法和行为发现，这些对于 TD 人群从 ITS-R 系统中受益至关重要。研究结果还将为辅助交通监管机构制定有效的财务和运营政策提供信息。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
