Summary
This report addresses the need for cost-effective, scalable data collection systems to improve the understanding of naturalistic near-crash and crash events in light vehicles. While existing field operational tests and naturalistic driving studies utilize comprehensive data acquisition systems, these packages cost over $10,000 per vehicle, limiting deployment to small fleets. The research aims to identify sensors that can be added to vehicles at a cost under $1,000 to enable large-scale deployment (5,000+ vehicles), thereby enhancing national crash databases like the National Automotive Sampling System (NASS) and allowing for more accurate assessment of crash avoidance technologies. The study defines functional requirements for Advanced Event Data Recorders (AEDRs) by analyzing pre-crash scenarios and causal factors from NASS/General Estimates System (GES) and Crashworthiness Data System (CDS) databases. The authors identified eleven dominant pre-crash scenarios, such as lead vehicle stopped and drifting, which account for approximately 82% of light vehicle crashes. They mapped these scenarios to specific data needs, including vehicle state, driver actions, and environmental conditions. The report then surveys current Event Data Recorder (EDR) technologies from Original Equipment Manufacturers (OEMs), aftermarket suppliers, and experimental systems to assess their capabilities, measured parameters, and costs relative to these defined requirements. Key findings indicate that a basic AEDR package can be developed for under $1,000, potentially below $500 if integrated with existing OEM sensors for anti-lock brakes and stability control. This basic package enhances standard crash EDRs by adding a positioning sensor, processor, storage, and an interior camera to capture driver causal factors. The analysis highlights that incorporating an "intelligent forward view" camera into this basic package is the most efficient method for capturing pre-crash events relative to cost. This camera measures vehicle position within the lane and the range/range rate to obstacles ahead. The report proposes six AEDR package configurations, ranging from basic crash-only recorders to advanced near-crash systems, and evaluates their benefits-to-cost ratios. The significance of this work lies in providing a roadmap for developing low-cost, high-impact data recorders that can be widely deployed. By capturing objective data on pre-crash dynamics and driver behavior, these AEDRs would significantly improve the quality of national crash data and support the validation of intelligent vehicle safety technologies. The authors conclude that while the sensory aspects of these systems are well-defined, further analysis is required to address data processing, storage, and retrieval mechanisms, as well as to characterize the performance of intelligent cameras under diverse driving conditions.
Key finding
A basic AEDR package costing under $1,000 that includes an intelligent forward-view camera is the most cost-effective configuration for capturing pre-crash events.
