Abstract

Apparatus and method for analyzing an electron beam including a circular sensor disk adapted to receive the electron beam, an inner semi-circular slit in the circular sensor disk; an outer semi-circular slit in the circular sensor disk wherein the outer semi-circular slit is spaced from the first semi-circular slit by a fixed distance; a system for sweeping the electron beam radially outward from the central axis to the inner semi-circular slit and outer second semi-circular slit; a sensor structure operatively connected to the circular sensor disk wherein the sensor structure receives the electron beam when it passes over the inner semi-circular slit and the outer semi-circular slit; and a device for measuring the electron beam that is intercepted by the inner semi-circular slit and the outer semi-circular slit.

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.
