Speaker Bios

Farhad Pooran brings three decades of experience in development and deployment of traffic management solutions. His experience has been gained through serving in various roles, including leading systems engineering, software development, business development as well as managing numerous projects in deployment and operations of advanced traffic signal control systems. Farhad joined Econolite Systems in 2017, leading product management and currently business development for systems products including adaptive control and ATSPM.

Greg Barlow is the founder and Chief Technology Officer of Rapid Flow, an intelligent transportation technology startup based in Pittsburgh, Pennsylvania. He is the co-inventor of the Surtrac adaptive traffic signal control system, originally developed in the Robotics Institute at Carnegie Mellon University. Greg is a member of the Traffic Signals Systems Committee of the Transportation Research Board, where he chairs the Technology and Standards subcommittee. He has a Ph.D. in Robotics from Carnegie Mellon University, and he has been working in the area of artificial intelligence and intelligent machines for over 20 years.

Reggie Chandra is the CEO of Rhythm Engineering and the inventor of In|Sync. He is an expert in Neural Networks and has implemented several Convolution and Recurrent Neural Network models in traffic engineering. His current research focus is to develop a completely self-learning Artificial Intelligence-driven In|Sync model.

Pete Marshall brings nearly 30 years of significant project experience in traffic engineering, adaptive control, consulting, and transportation systems management. He has worked extensively in technology implementation roles on alternative delivery roadway projects including large scale technology deployments for state DOT clients. He is thoroughly familiar with the challenges of integrating high technology ITS systems on large roadway projects under heavy traffic demand. He is a key advisor on numerous Siemens adaptive projects and understands the solutions set and how to customize it to unique customer needs, given their detection requirements and roadway elements.

Marshall Cheek joined Trafficware in 2011 and is currently the Director of Services, responsible for systems deployments domestically and abroad.  Projects under his supervision have included statewide traffic central management system projects, connected vehicle projects, as well as some of the largest adaptive signal control systems in the United States.  Marshall is a licensed professional engineer (PE) in Texas and Florida and earned his Bachelor’s degree from Iowa State University and his Master’s from Texas A&M University.
