CrossTraffic: An Open-Source Framework for Reproducible and Executable Transportation Analysis and Knowledge Management

This silver document aggregates multiple new arXiv CS/AI papers (Apr 21, 2026) spanning transportation engineering, education, healthcare, market effects of AI rhetoric, organizational readiness, robotics ethics, and human mobility. Key contributions: (1) CrossTraffic — an open-source, ontology-driven framework and executable core for reproducible transportation analysis with a conversational LLM interface; reported near-zero numerical error (MAE<0.50) and perfect detection of invalid inputs; code published on GitHub. (2) TRACE — a scalable EHR preprocessing pipeline that removes “note bloat”;
