Title: Integrated Transportation Conformity Analysis
Speaker: Heng Wei, Ph.D., P.E., Associate Professor, The University of Cincinnati
[Abstract] Alleviating highway congestion and traffic-source environmental impacts has been viewed as one of strategies to address issues related to transportation greenhouse gases (GHGs) and sustainability. One essential challenge lies in the capability to quantitatively assess the effect of the advanced planning and traffic management and control strategies on reduction of relevant carbon footprint. It is desired to enable the “what-if” scenario-based analysis to identify adaptive changes in land use and social economy that are aimed to reduce or minimize the impact of the transportation activities on road emission and air quality. The speaker will present a framework to fill in the gap through developing a Geographical Information System (GIS)-based Roadway Air Impact Analysis (RAIA) system with user-friendly functions for developing planning scenarios and leveraging predominant traffic data sources available at regional or state level. The RAIA system involves systematic integration of travel demand forecasting, vehicle emission, and vehicle powered energy consumption models with a friendly-heuristic data flow interfaces. The air quality measures, such as AQI and NAAQS, are embedded into the RAIA system. Such an integration effort will be greatly beneficial to identifying strategic solutions to design and operate transportation systems in an attempt to satisfy the transportation conformity requirements, and provide supportive information for measuring and assessing sustainability of transportation systems.
[Short Biography] Dr. Heng Wei is an Associate Professor of Transportation Systems and Engineering at The University of Cincinnati (UC). He has a wide spectrum of research interests and expertise in transportation systems, including ITS, traffic operation and management, safety and control, transportation source air environmental analysis, artificial intelligent techniques and computing technologies in transportation, traffic flow theory and microscopic traffic simulation modeling, travel demand forecasting, and GIS application in transportation. Since his faculty appointment at UC, he has secured 29 research projects (including 7 Co-PI projects) from ODOT, FHWA, NSF, OTC, EPA, and UC URC/FDC. His research has resulted in 146 peer-reviewed papers and 9 professional books/chapters. He is a member of numerous outstanding professional committees, such as TRB ABE90 and ABJ70 Committees, ASCE T&DI Committees on Advanced Technology Committee and Transportation Safety and on Sustainability and Environment. He is the Chair of IEEE ITSS Travel Information and Traffic Management Committee and President of Chinese Overseas Transportation Association (COTA). In addition, he has successfully organized and/or chaired 14 international conferences/sessions and symposiums.
