Automatic vehicle monitoring (AVM) and vehicle health monitoring (VHM) are becoming more widely utilized by transit agencies across the United States. These agencies are increasingly interested in using predictive maintenance technology (PMT), artificial intelligence (AI), and other technologies, but the overall capabilities and benefits of these technologies are still emerging.

TCRP Synthesis 185: Use of Automatic Vehicle Monitoring, Vehicle Health Monitoring, and Diagnostic Systems by Transit Agencies, from TRB's Transit Cooperative Research Program, explores how AVM, VHM, and other technologies are utilized to monitor an array of onboard vehicle components in order to assist in the early identification of potential mechanical issues, thus supporting effective maintenance practices.
