Evaluating LLMs for Roadway Design Compliance: An MUTCD-Based Evaluation of GPT-4 and Claude 3.5
Traffic design has long relied on rule-based frameworks, empirical data, and professional judgment to ensure safe and efficient roadway operations. Practitioners frequently consult design manuals such … [Read more...] about Evaluating LLMs for Roadway Design Compliance: An MUTCD-Based Evaluation of GPT-4 and Claude 3.5
Digital Twins for Detecting Worker Geofence Violations in Road Construction Work Zones
Work zone intrusions have been recognized as a safety-critical incident in road construction, often leading to injuries and fatalities. The causes of intrusions are twofold: (i) driver recklessness or … [Read more...] about Digital Twins for Detecting Worker Geofence Violations in Road Construction Work Zones
