Amit Kumar Das is a researcher and academic in Civil/Transportation Engineering with expertise in traffic flow theory, simulation modelling, and urban transportation systems. His published work in reputed international journals focuses on cellular automata applications for heterogeneous traffic, lane-changing behaviour, work zone traffic operations, pedestrian movement analysis, and level of service assessment of urban streets using advanced clustering techniques. He has contributed to developing context-specific traffic performance models suited to mixed traffic conditions in developing countries. His research integrates engineering principles, computational modelling, and field data analytics to improve roadway efficiency, safety, and mobility planning. He is particularly interested in intelligent transportation systems, traffic operations, and evidence-based solutions for sustainable urban mobility.
