Urban Transportation, Land Use, Air Quality, and Health

An interdisciplinary household survey in the city of Chengdu, led by Chris NIELSEN (Harvard-China Project), James HAMMITT (Harvard T.H. Chan School of Public Health), and SHEN Mingming and YAN Jie (School of Government, Peking University), was completed in July 2016. The data have been joined with an earlier dataset collected in a nearly identical Harvard-China Project-PKU survey in 2005, to yield a time series covering changes in Chengdu's economy, urbanization, travel behavior, land use, air quality, and environmental health over 11 years. In addition to this multi-faceted research on Chengdu, the Project conducts additional individual studies of transportation, land use, emissions, air quality, and/or health at urban scale.

Both the 2005 and 2016 Chengdu surveys collected data across a wide range of research interests, including transportation planning, travel behavior, mobile-source emissions, outdoor and indoor air pollution exposures, health effects of air pollution, and perceptions and valuation of health risk. Harvard researchers devised the questionnaires and are leading a number of parallel analyses. Covering 2000 households, field implementation of both surveys was led by political scientist Shen, using RCCC's rigorous geospatial sampling methods to insure inclusion of non-registered migrants left out of most social surveys in China.  
 
Joining Hammitt and Nielsen in ongoing analyses of the datasets are China Project research affiliates GUAN ChengHe (Graduate School of Design, Harvard), Sumeeta SRINIVASAN (Department of Urban and Environmental Policy and Planning, Tufts University), WANG Haikun (School of Environment, Nanjing University), and GENG Fangli (Harvard T.H. Chan School of Public Health).
