The main objective of this paper is to implement and test active traffic management (ATM) strategies on a Brazilian freeway segment in order to assess and quantify the effectiveness of these strategies. Active traffic management dynamically manages traffic flow based on existing traffic conditions. Simulation software VISSIM was used to evaluate the simulated ATM strategies, and was calibrated to reflect the freeway driver’s behavior. Simulated ATM strategies were speed harmonization and temporary use of hard shoulders. The results showed that active traffic management has a positive impact on traffic operation and benefits of the modeled strategies included: shorter headways, reduction in travel times, reduction in travel time variability and reduction in number of lane changes. Tested strategies also reduced the duration of congestion, increasing the efficiency of the segment under analysis.
