Biography

Dr. Xiao-Yun Lu, is a research engineer at California PATH.  He earned a Bachelor of Science in Mathematics from Sichuan University, China (1982), a Master of Science in Applied Mathematics from the Institute of Systems Science, Chinese Academy of Sciences (1985), and his Ph. D. in Systems and Control from University of Manchester, UK (1994).

Dr. Xiao-Yun Lu worked as a research associate at University of Leicester UK (1994-1999) and joined PATH in April 1999. He has 29 years of experience in systems modeling, control and optimization and 14 years of experience with specialized expertise in traffic systems detection, modeling, control design, micro/macro simulation, real-time implementation, and vehicle system modeling and longitudinal control.  His recent significant accomplishments include:

  • freeway corridor traffic detection, modeling, simulation, optimal control algorithm development with combined Variable Speed Limit (VSL) and Coordinated Ramp Metering (CRM); 
  • coordination of freeway ramp metering and arterial corridor intersection traffic signal control;
  • vehicle speed estimation using signal loop event data;
  • VSL conceptual implementation: VSL along a freeway corridor calculated based PeMS 30s real-time traffic data and feed back to the driver on CACC vehicle with (I2V);
  • control design, simulation, implementation and field test in Nevada of 3-truck platooning for mobility and energy efficiency improvement using DSRC V2V;
  • coordinated merging algorithm development and implementation on 3 passenger cars;
  • freeway saturated traffic shock wave analysis from NGSIM data;
  • driver safe following distance advisory; systematic loop fault detection and data correction; and
  • freeway non-recurrent bottleneck quick detection with sub-second loop data.

He is a member of TRB Traffic Monitoring Committee (ABJ35) and ATM (Active Traffic Management) Subcommittee; reviewer of Mathematical Review.
