However, due to industry development, rise of car ownership and city construction, air pollution, especially particulate matter (PM2.5/10), has become a significant issue in urban environment. According to previous studies, PM exposure is associated with a danger of respiratory diseases while maximum daily concentration and annual average concentration of PM2.5 in many big cities in China exceeds the standard of air quality, which has drawn greater public concern. In this context, weather bureau and other commercial companies began to provide real time broadcast and forecast of PM2.5 concentration. But the existing forecast of PM2.5 concentration is more focused on a city scale or even national scale, which has little practical use for daily trip guide that directly related to everyday life and personal health. This research attempts to provide roadrunners a less affected route and suggest less affected places for outdoor activities. A correlation between PM concentration data and congestion index is established to represent the healthy level of built environment. The research comprises two spatial scales. At the city scale, we conduct a cross-sectional survey of 849 people living in Shanghai, among which 267 people had lung cancer. The survey consists of factors of individual level, such as age, smoking status and cooking habits; dwelling unit level, such as per capita living space and house age; and residential community level, such as external traffic volume and surrounding land use.EnglishopenAccessconferenceObject980-982
