Abstract

A system and method of generating a coiled actuator fiber. The method includes twisting a fiber to generate a twisted fiber, wrapping the twisted fiber around a core to generate a coil in the twisted fiber; and removing at least a portion of the core to generate a coiled actuator fiber. In some aspects that fiber can be a yarn with one or more fibers or a fiber comprising a single elongated element. In some aspects, a portion of the core includes a removable sacrificial portion. The removable sacrificial portion can be dissolvable in a solvent or physically removable. In some aspects, the core further includes a non-dissolvable portion that is not dissolvable and generating a coiled actuator can include removing the sacrificial portion by treating a twisted fiber on the core to remove the sacrificial portion and leaving the non-dissolvable portion.

Large language models for transportation research: Methodologies, state of the art, and future opportunities

The rapid rise of large language models (LLMs) is transforming transportation research, with significant advancements emerging between 2023 and 2025, a period marked by the inception and swift growth of adopting and adapting LLMs for various transportation applications. Despite these significant advancements, however, a systematic review and synthesis of the existing literature remains lacking. This paper aims to fill this gap by providing a comprehensive review of the methodologies and applications of LLMs in transportation. We explore key applications, including autonomous driving, travel behavior prediction, and general transportation-related queries, alongside LLM methodologies such as zero- or few-shot learning, prompt engineering, and fine-tuning. From the review, critical research gaps are identified. From the methodological perspective, many of the research limitations can be addressed by integrating LLMs with existing tools and refining LLM architectures. From the application perspective, research opportunities for LLMs to address various transportation challenges are also explored. By synthesizing these findings, this review not only presents the state-of-the-art LLM adoption and adaptation in transportation, but also proposes future research directions as well as insights and recommendations for policymakers and practitioners, paving the way for greater LLM-driven research innovations in transportation in the future.
