Reducing Proximity Errors for Exposure to Traffic –Related Air Pollution


Positional error and time-activity patterns in near-highway proximity studies: an exposure misclassification analysis(28 page pdf, Kevin J Lane, Madeleine Kangsen Scammell, Jonathan I Levy, Christina H Fuller, Ron Parambi, Wig Zamore, Mkaya Mwamburi, Doug Brugge, Environmental Health, Sep. 8, 2013)
