Informing infrastructure interventions via novel near-miss data collection
By: VELO.AI, INC.
Project Objective & Overview
Developed and deployed a scalable, AI-driven sensor system to detect, record, and analyze near-miss interactions between vehicles and Vulnerable Road Users (VRUs). The project addresses the critical gap in traditional safety analysis by moving beyond sparse crash data to actionable, proactive near-miss observations.
Problem Statement: Reliance on historical crash data ignores high-frequency "near-miss" events, delaying safety interventions until accidents occur.
Pilot Site: Pittsburgh, PA (Urban and mixed-traffic environments).
Partners: POGOH (Bikeshare Fleet), Carnegie Mellon University Mobility Data Analytics Center (Research), City of Pittsburgh (Advisory).
Key Results & Findings
Fleet Deployment: Collected 1,000+ miles of data via consumer/bikeshare fleets, capturing confirmed near-misses and collisions.
Predictive Modeling: Built region-wide predictive safety model with CMU, extrapolating localized risk to the full city network.
Advanced Analytics: Validated surrogate safety measures (passing distance/speed) and prototyped 3D event reconstruction.
Infrastructure Assessment: Mapped road surface quality (potholes) and traffic congestion using IMU and vision data.
Challenges: Retrofitting bikeshare fleets proved complex; future scaling requires factory integration.
