Proper calibration process is key for traffic safety evaluations using simulation models. Allowing for a with and without comparison under controlled environment that is not directly testable in the field, microsimulation-based approach has drawn considerable attention for the performance evaluation of emerging technologies, including connected vehicle (CV) safety applications. Different from the traditional approaches to evaluate mobility impacts, safety evaluations of such applications demand the simulation models to be well calibrated to match real-world safety conditions. This seminar will present a novel calibration framework which combines traffic conflict techniques and multi-objective stochastic optimization to calibrate the operational and safety measures simultaneously. The conflict distribution of different severity levels categorized by time-to-collision (TTC) is applied as the safety performance measure. Simultaneous perturbation stochastic approximation (SPSA) algorithm, which can efficiently approximate the gradient of the multi-objective stochastic loss function, is used for model parameters optimization that minimizes the total simulation error of both operational and safety performance measures. A case study will be demonstrated by calibrating a microscopic simulation model to evaluate CV safety applications as a part of the NYC Connected Vehicle Pilot Deployment Program.
Dr. Kaan Ozbay is a Professor at New York University's Tandon School of Engineering, and Director of C2SMART Center, a Tier 1 USDOT University Transportation Center. Dr. Ozbay served as Principal Investigator (PI) of the NYU/C2SMART team as part of the NYCDOT-led New York City Connected Vehicle Pilot, under USDOT's Connected Vehicle Pilot Program. He joined NYU's Department of Civil and Urban Engineering and Center for Urban Science and Progress (CUSP) in August 2013, and is also Global Network Professor of Civil and Urban Engineering, NYU Abu Dhabi (NYUAD) and Global Network Professor of Engineering and Computer Science, NYU Shanghai (NYUSH).
UPCOMING: Connected Vehicle Applications: Lessons Learned and Future Research & Deployment Roundtable

The USDOT Connected Vehicle (CV) Pilot Program sought to test vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) applications to improve transportation systems, mobility, and safety with real-world deployments in New York City, Tampa, and Wyoming.

This roundtable discussion will focus on these recently completed connected vehicle pilots and the lessons learned. Our panelists will feature practitioners, decision-makers, and researchers involved in CV deployments and leading the way for their wide-scale adoption. Featuring:

  • Sisinnio Concas, Program Director, Autonomous & Connected Mobility Evaluation (ACME), University of South Florida
  • Mohamad Talas, Deputy Director of ITS System Engineering, New York City Department of Transportation
  • Billy Chupp, Engineer, Volpe National Transportation Systems Center
  • Karl Wunderlich, Director, Surface Transportation Systems, Noblis
  • Kaan Ozbay, Professor & Director, C2SMART Transportation Center, New York University

This roundtable caps off C2SMART’s State of the Field: Connected Vehicle Applications series, and there will be a synthesis of prior presentations and a discussion on future directions and applications for research, testing, and deployment.
