Roberto Horowitz is a Professor in the Department of Mechanical Engineering at the University of California, Berkeley (UC Berkeley) and holds the James Fife Endowed Chair in the College of Engineering. He received a B.S. degree with highest honors in 1978 and a Ph.D. degree in 1983 in mechanical engineering at UC Berkeley and has been a faculty member in the same department since 1982. Dr. Horowitz teaches and conducts research in the areas of adaptive, learning, nonlinear, stochastic, optimal and robust control, with applications to traffic modeling, estimation and management, Intelligent Vehicle and Highway Systems (IVHS), mechatronics, and robotics.

Dr. Horowitz is currently the co-principal investigator (PI) of the Connected Corridors Project at PATH, which is a large 5-year Caltrans-funded program to develop and demonstrate through a pilot, a next generation Active Transportation and Demand Management (ATDM) system in a freeway traffic corridor in California. Dr. Horowitz is currently responsible for leading, together with Drs. Alex Bayen (PI) and Pravin Varaiya, the formulation, design, implementation and testing of Analysis, Modeling, Simulation (AMS) and decision support tools for performing real-time traffic estimation and short-term prediction, and for evaluating potential traffic management strategies in a California freeway corridor.

Dr. Horowitz is currently PI of the Tools for Operations Planning (TOPL) Project at PATH. This Caltrans-funded project, which is in its sixth year, is developing a set of macroscopic tools for modeling large freeway traffic corridors in the state of California, and quickly evaluating the potential performance and safety gains that can be achieved by ATDM strategies such as ramp-metering, variable speed limit, incident management, re-routing and freeway lane management. This project is also developing the macroscopic AMS basis for the decision support system in the Connected Corridors Project.

Dr. Horowitz has directed, together with Dr. Pravin Varaiya, several PATH/Caltrans and NSF sponsored projects dealing with the modeling, calibration, estimation, analysis and control of freeway traffic corridors, as well as the field test implementation of on-ramp queue estimation and traffic- responsive on-ramp metering algorithms. Dr. Horowitz has been involved in the formulation, design, testing, and verification of many maneuvers and control laws for PATH’s Automated Highway System (AHS) control architectures. He also headed several research projects on the development of integrated meso/microscale traffic simulation software for testing fault detection and handling in an AHS, and the development of enhanced coordination and link layer control algorithms for improving the AHS capacity.

Dr. Horowitz received an IBM Young Faculty Development Award in 1984, an NSF Presidential Young Investigator Award in 1987, and a Japanese Ministry of Education Foreign Researcher Award in 1997. He is co-author of the paper Mixture Kalman filter based highway congestion mode and vehicle density estimator and its application, which won the 2005 American Automatic Control Council (AACC) Hugo Shuck Best Application Paper Award. Dr. Horowitz is the recipient of the 2010 ASME Dynamic Systems and Control Division (DSCD) Henry M. Paynter Outstanding Research Award, which is given biannually to a DSCD member who has demonstrated sustained outstanding research contributions, either basic or applied, as a mechanical engineering professional to fields of interest to the DSCD. Dr. Horowitz has supervised 37 Ph.D. students to completion at UC Berkeley.
