The Environmental Trade-offs of AI in Transportation Research

Abstract:

How the growing use of AI in transportation research brings both new insights and significant environmental costs. The talk focuses on the trade-offs between the computational footprint of AI methods (training, inference, large-scale simulations) and the value they add to transportation research outcomes, especially in sustainability-related work. My goal is to highlight how our field can balance methodological innovation with responsible use of computational resources.

A scholar, a mentor, a friend …. Prof. Hani Sobhi Mahmassani passed away on July 15, 2025. For many of us, the Transportation Research Board Annual Meeting will not be the same without his presence. With his long list of contributions to TRB as committee member, chair, review coordinator, session organizer, author, presenter, panelist …. Hani became the epicenter of many of the events we attended. He was a leading authority in the transportation sector with his knowledge and expertise sought by government agencies, private companies and academic institutions around the world. He was a member of the National Academy of Engineering with invaluable contributions to the field. A litany of honors testifies to Hani’s significance and standing in the world of transportation science. This session will offer a chance for attendees to describe Hani’s irreplaceable role in our community and how he impacted TRB and its work.

The Reverse Side of Online Shopping: Examining Sociodemographic and Built-Environment Determinants of Delivery Returns

The rapid growth of e-commerce has created new transportation challenges through increased product returns, yet the behavioral determinants of delivery return patterns remain understudied from a consumer-centric perspective. This research develops a comprehensive econometric framework to analyze online shopping frequency, delivery return rates, and return channel preferences using data from the 2022 National Household Travel Survey (NHTS). We employ a multivariate modeling approach integrating probit ordered-response and probit fractional response models to examine three interconnected outcomes: (1) frequency of online goods purchases, (2) proportion of online purchases returned, and (3) distribution of returns across four channels (home pickup, post office, Amazon drop-off, and physical store). The results reveal significant sociodemographic heterogeneity in online purchasing and return behavior. Built environment factors also significantly influence return behaviors. The findings have important implications for transportation planning and urban logistics, highlighting the need for policies that ensure equitable return access and the importance of integrating e-commerce return trips into travel demand models.

Keywords: E-commerce returns, online shopping behavior, transportation planning, reverse logistics, consumer behavior.
