Research shows the use of roadway networks generate health risks thus, the amount of time people use these networks has direct implications for public health. Our research hypothesizes a credible link exists between commuting distance, land use policy, and health outcomes. To date, the primary means of investigating commuting distance has been regarding socio-economic status and the primary means of investigating land use policy has been regarding changes in travel behaviour. In both cases researchers have neglected the domain of public health linking to structural policy factors. Our research advances this topic by hypothesizing that minimum lot size policy directly affects commuting distance which, in turn, increases exposure to road related adverse health outcomes. We use econometric analysis on county/city level data to estimate the effects of commuting distance on emissions, accident rates, and cardiovascular disease, as well as, the effects of minimum lot size on work-trip length.
