Under the supervision of Professor Samer Hamdar, the Center for Intelligent Systems Research conducts research activities in mainly three areas. The first area is related to vehicular and pedestrian traffic dynamics where multiple data sources (driving simulator, instrumented vehicle, detectors and data libraries) are utilized to calibrate and validate newly developed and existing models in different weather and infrastructure-related conditions. The second area focuses on disaster management and evacuation analysis. The research team is studying how social networks may be translated into transportation demand loading patterns in response to different information propagation strategies. The third area aims to build more sustainable multi-modal networks with special attention to non-motorized transportation modes. The corresponding research activities are partially funded by the Civil Infrastructure Systems Program at the National Science Foundation.
