Abstract Whilst various studies have looked at traffic-related air pollution and mortality, the overall evidence base remains mixed. Additionally, most of these studies are large cohort studies that are not easily replicable or timely. Our aim is to develop an approach that will provide a rapid but good-enough estimate of the effects of traffic related air pollution for use by local planners and environmental and public health teams.We identify four specific cause of death groups. For each death we use residential postcode to find the distance to the neatest traffic count point (node). Using 'All other' deaths as our reference group we calculate the odd ratio (OR) for each death group at various distances from a node. Only mortality from COPD showed a significant association with distance from a node, OR at 0-100m 4.29 (95% CI 2.03-9.06, p-value<0.01). We also find associations with being male, increasing deprivation and traffic intensity. This implies that if 10% of the population lived near a main road, 25% of CPOD deaths are attributable to living there.Using publically available traffic data as a proxy for air pollution exposure we have developed an approach to estimate the effect of traffic related air pollution. Our results suggest that living within 100m is strongly associated with increased numbers of COPD deaths which is in-line with the wider literature. Larger studies will be needed to validate this technique, but if successful it could present a “low cost” technique to understand the population level effects of local pollution levels.
