We presented our work on data-driven smart mobility at the Workshop on Smart Cities & Connected Communities. This Workshop aims to bring together leaders in community and economic development, government, science, and technology to chart a course for future R&D investment and build collaborative private, non-profit, and public sector partnerships that address sustainability challenges for livable communities. Our work combined social medi
We presented our work on optimized particle-based computational simulation at the ICHMT International Symposium on Advances in Computational Heat Transfer (CHT), Piscataway, NJ. We present an optimized particle-based computational method for studying kinetics, computing nucleation rate, and analyzing mechanism of both homogeneous and heterogeneous bubble nucleation. As a rare event, bubble nucleation is difficult to study with traditional computa
As the lead inventor of smart and scalable urban traffic control, Dr. Xie presented his work at FHWA Turner-Fairbank Research Center. Scalable urban traffic control system has been developed to address current challenges and offers a new approach to real-time, adaptive control of traffic signal networks. The system exploits a novel conceptualization of the signal network control problem as a decentralized process, where each intersection in the n
During January 11-14, we presented our work on understanding and improving urban mobility at the Transportation Research Board (TRB) 94th Annual Meeting in the Walter E. Washington Convention Center, Washington, DC. An empirical study of combining participatory and physical sensing to better understand and improve urban mobility networks. Transportation Research Board (TRB) Annual Meeting, Washington, DC, USA, 2015. An unsupervised learning appro
On October 10, Dr. Xie presented the work on multimodal urban traffic control at the 2014 IEEE International Conference on Intelligent Transportation Systems, Qingdao, China. This work extends our decentralized, schedule-driven approach to traffic network control in the direction of a broader mobility objective to optimize all modes of traffic that are central to sustainable urban living. We focus specifically on accommodating pedestrians and opt
On Aug 11-12, we attended Workshop on Big Data and Urban Informatics, with support from the National Science Foundation, held at the University of Illinois at Chicago (UIC). “The workshop brought together researchers from diverse disciplines motivated by sustainability and social equity concerns, the need for efficient resource management, and a desire to leverage technological developments that have the potential to provide solutions to th
Presented the work on tackling real-world changes and the integration with a unified route choice framework for the smart and scalable urban traffic control system at the Transportation Research Board (TRB) Annual Meeting, Washington, DC.
We presented our poster on the initial smart and scalable urban traffic control (SURTRAC) system at the Transportation Research Board (TRB) Annual Meeting, Washington, DC. SURTRAC is a packing box encapsulating the core control engine, including schedule-driven intersection control (SchIC) and decentralized coordination mechanisms, with some strengthening strategies to enable its real-world operations.
On Jul 15, we demonstrated the work on real-time adaptive traffic signal control for the NACo (National Association of Counties) Annual Conference and Exposition, Pittsburgh, PA.
We presented the work on coordinated look-ahead scheduling for smart and scalable urban traffic control in the 2012 International Joint Conference on Autonomous Agents and Multiagent Systems (AAMAS), at the Polytechnic University of Valencia, Spain. The work is a real-time, smart and scalable, adaptive traffic signal control system that optimizes the highly dynamic traffic flow in complex (grid-like) urban road networks. Its core control engine i
