Active traffic management (ATM) is the ability to manage recurrent and nonrecurrent congestion, both dynamically and proactively, on transportation infrastructure based on real-time or predicted traffic conditions. Focusing on trip reliability, ATM strategies maximize the effectiveness and efficiency of a facility while increasing throughput and enhancing safety.
NCHRP Research Report 1120: Active Traffic Management Strategies: A Planning and Evaluation Guide, from TRB's National Cooperative Highway Research Program, is designed to provide planning and evaluation guidelines to transportation agencies so they can easily identify the appropriate path forward with ATM strategies suited to their regional needs and characteristics.
