Active Traffic Management Strategies
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. In addition to NCHRP Research Report 1120, an associated publication, NCHRP Web-Only Document 402: Developing a Planning and Evaluation Guide for Active Traffic Management Strategies, documents the research undertaken for the project.
