Summary

This research addresses the need for minimum uniform standards for a biometric identification system for Commercial Motor Vehicle (CMV) drivers, mandated by the 1988 Truck and Bus Safety and Regulatory Reform Act. The primary goal is to enforce the "one-driver, one-license, one-record" policy established by the Commercial Motor Vehicle Safety Act of 1986, thereby preventing unsafe drivers from holding multiple Commercial Driver’s Licenses (CDLs). While a 1990 study identified fingerprinting and retinal scanning as promising technologies, further development was required to meet operational requirements. This study, initiated in October 1995, aimed to evaluate the current status of biometric technologies, determine their cost-effectiveness for large-scale applications, and provide recommendations to the Secretary of Transportation. The methodology involved reviewing all commercially available biometric systems, including signature verification, voice recognition, iris scans, and facial images. Researchers established functional requirements in collaboration with the American Association of Motor Vehicle Administrators (AAMVA), stipulating that the system must capture identifiers within 30 seconds, be unobtrusive, and ensure positive identification over an indefinite period. Additional criteria required the technology to prevent multiple license possession, have proven performance in large-scale applications, and support multi-vendor interoperability. Fingerprinting was identified as the only technology meeting these criteria. To assess performance, researchers developed mathematical models for Automatic Fingerprint Identification System (AFIS) parameters, including penetration rate, bin error rate, and false match/non-match rates. These models were validated using data from a 1997 benchmark test involving four vendors in the Philippines. The study also evaluated three system architectures: federal centralized, state-level distributed with centralized communication, and state-level distributed with direct communication. The findings indicate that a single-print AFIS system fails to meet functional requirements, exhibiting an 11 percent false non-match rate and a 99 percent false match rate against a database of 8.5 million prints. In contrast, a two-finger system approximately meets requirements for both verification and identification modes. Consequently, the study recommends adopting fingerprinting as the standard biometric identifier, specifically using a two-print system involving thumbs or index fingers. Regarding system architecture, a federal centralized system was determined to be the most cost-effective approach, with no technical barriers to implementation. The report further recommends adapting existing image quality, data compression, and data format standards from the FBI, ANSI, and NIST, while suggesting AAMVA monitor the development of feature set standards despite vendor opposition. The significance of this research lies in providing specific, actionable standards for implementing a national biometric identification system for CMV drivers. By identifying fingerprinting as the viable technology and outlining necessary technical and operational standards, the study supports states in complying with the 1998 Transportation Equity Act for the 21st Century. The recommendations facilitate the creation of a secure, efficient, and interoperable system to enhance highway safety by ensuring accurate driver identification and preventing license fraud.

Key finding

A two-fingerprint system using Automatic Fingerprint Identification Systems is the only configuration that approximately meets the functional requirements for accuracy and error rates, while a single-fingerprint system fails to satisfy these standards.
