A Land Use Regression Road Map for the Burrard Inlet Area Local Air Quality Study Prepared for the Greater Vancouver Regional District by:

Preface This report has been prepared by its authors based on a scope of work prepared by the Greater Vancouver Regional District. While the report has been reviewed by representatives of the GVRD as sponsors of the study, the findings and conclusions expressed in this report are the opinion of the consultant authors, and do not necessarily represent the opinion of the GVRD. Background Several recent studies have measured and reported considerable spatial variability in the concentrations of traffic-related pollutants within urban areas (1-13). These " neighborhood scale " intra-urban differences tend not to be well-characterized by air quality monitoring networks, suggesting that exposure variation within the population is not well-characterized by regulatory monitoring networks. Land use regression (LUR) was first developed by public health researchers to address this misclassification of exposure, and the method has recently gained attention in the air quality management and urban planning communities.
