Dr. Yinhai Wang, Professor at the University of Washington at Seattle and Director of the STAR Lab and PacTrans, will be speaking on "Big-Data-Driven Transportation Decision Making in the Smart Cities Context".
Transportation involves human, infrastructure, vehicle, and environmental interactions and is therefore a very complicated system. Transportation activities are found affecting public health, air quality, sustainability, etc., and thus tie to everyone’s daily life and are critical for achieving goals of Smart Cities. Traditionally, transportation has been studied through classical methods, typically with ideal assumptions, limited data support, and poor computing resources. While the theories (such as traffic flow and driver behavior models) developed through these efforts provide valuable insights in understanding transportation-related issues, they are often ineffective in large-scale transportation system analysis with massive amount of data from various sources.
With recent advances in sensing, networking, and computing technologies, more and more cities have launched their smart cities plans to improve quality of life, sustainability, efficiency, and productivity. Sensor networks are fundamental elements of smart cities and the data they produce have the potential of generating the intelligence needed to make urban transportation smarter. We expect that many new transportation-related data and computational resources will become available in the smart cities context. These new assets are likely to bring in new opportunities to understand transportation systems better and address those critical transportation issues in a faster, more accountable, and more cost-effective way. To take advantage of these big data, a new theoretical framework and its supporting platform are clearly needed to integrate the quickly growing massive amount of data, typically from numerous sources of varying spatial and temporal characteristics, into the large-scale transportation problem solving and decision making processes. Efforts along this line are likely to form up a new subject area, namely e-science of transportation, in the years to come. Through his talk, the speaker will share his vision and pilot research on extracting transportation big data streams from the smart cities sensor networks and demonstrate the values of these data in large-scale system analysis and decision support through an online regional-map-based data platform named Digital Roadway Interactive Visualization and Evaluation Network (DRIVE Net).
