Abstract

The purpose of this report is to describe the anticipated performance of LLNL’s bispectral speckle imaging algorithm on specific imaging scenarios and further evaluate the regime over which bispectral speckle imaging can be used to compensate for atmospheric turbulence. This includes investigating a number of relevant Cn2 cases and multiple wavelengths. The anticipated performance described here will be evaluated based upon simulated imagery. As with any simulation, it must be realized that the full truth of the matter will be determined when real data is analyzed. This report assumes some basic familiarity with bispectral speckle imaging.

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.
