Adapt-Traf: An adaptive multiagent road traffic management system based on hybrid ant-hierarchical fuzzy model

•An adaptive vehicle route guidance system is developed.•The system is based on the ant colony behavior and the hierarchical fuzzy model.•The system allows adjusting efficiently the road traffic according to the real-time changes in road networks.•Multiagent simulations explain the improvement of the global road traffic quality in the road network.•The system deals with traffic congestion phenomenon.
