A two-stage joint modeling framework for evaluating the effectiveness of Midblock Pedestrian Signals (MPS).

INTRODUCTION This study evaluates the safety effectiveness of newly implemented Midblock Pedestrian Signals (MPS) at 14 locations across Florida. Data collection and processing: A total of 2,645 pedestrian-vehicle interactions were extracted from CCTV footage and processed using advanced computer vision techniques. Ped...

Crash Narrative-Guided Countermeasure Recommendation Using Large Language Models: A Retrieval-Augmented Generation Framework for Intersection Safety

A crash narrative-guided retrieval-augmented generation (RAG) framework that translates narrative-derived crash mechanisms into site-specific countermeasure recommendations and demonstrates the potential of retrieval-augmented LLMs as an interpretable and scalable decision-support tool for transportation agencies for t...

Vision-language and generative models in traffic video safety analysis: a computational framework and research agenda.

A unified taxonomy is proposed that maps model families to three application levels across diverse deployment environments-from cloud to onboard systems: network-scale monitoring, event-level crash and near-miss understanding, and generative or counterfactual scenario analysis.
