Saif Eddin Jabari,

Assistant Professor, NYUAD; Research Assistant Professor

Civil and Urban Engineering

Saif Jabari is an Assistant Professor of Civil and Urban Engineering at New York University in Abu Dhabi and also holds an appointment with New York University Tandon School of Engineering as Research Assistant Professor.  His research interests lie at the interface between data analysis and theoretical traffic flow modeling.  One of the main themes of his research is the development of methods for understanding and quantifying uncertainty in transportation systems.  His recent work has focused on the development of real-time traffic analytics, including traffic state estimation, network-wide real-time dynamic control, and incident detection, localization, and sensor placement problems for urban traffic networks.

Prior to joining NYUAD, Jabari was a Post-Doctoral Researcher in the Mathematical Sciences and Analytics Department at the IBM T.J. Watson Research Center in Yorktown Heights, NY.  Jabari received his Ph.D. in Civil Engineering from the University of Minnesota, Twin Cities in 2012 and his B.Sc. degree in Civil Engineering from in the University of Jordan in 2001. His doctoral dissertation received the 2012 Milton Pikarsky Memorial Award for best dissertation in Science and Technology.

Traffic Network Sensor Placement (no. US9466209 B2), (Utility)

Locations for traffic sensors can be determined by a computer system that identifies a particular segment of a travel path. Traffic flow data from other segments of travel path are accessed based on traffic flow characteristics of the particular path. Using the traffic flow data, parameters for a traffic incident symptom propagation model are generated, and a location of a traffic incident along the segment of the path is determined. Using time-to-detection limits and the incident model, upstream and downstream distances are determined, and the locations of two sensors are identified based on the distances.

Traffic Incident Location Identification (no. US9286797 B1), (Utility)

A location for a traffic incident can be determined by a computer system, using data from a first and second sensor along a travel path. A receiving and sending symptom of the traffic incident are detected from a first and second sensor, using traffic flow data from the sensors. The locations of the first and second sensors are determined. The location and traffic flow data from each sensor are used to create a sending and receiving profiles. From the profiles, a convergence formula is build. Using the convergence formula and by determining a convergence point for the sending and receiving symptoms, a time and location of the traffic incident is identified.
