Summary on Grant Application Form
DAPPLE is a large consortium project, focusing on a case study of traffic and air flow in building lined streets close to the intersection of Marylebone Road and Gloucester Place in Central London, to gain understanding that will be applicable to building-lined city streets in general as well as London in particular. Imperial College will make a central contribution to the project in two areas: 1) combining mean flow & turbulence data with vehicle emissions data at high spatial and temporal resolution to identify what factors have the greatest influence on the spatial and temporal variability of air pollution fields close to city streets, and 2) carry out an assessment of the air pollution exposure of people moving through the city streets as well as in roadside buildings, identifying the capability of operational air dispersion modelling techniques to capture the important features that control exposure and its variability. The flow and turbulence data will be coming from wind tunnel experiments at Surrey, computational modelling at Surrey and our own at Imperial, and from the field measurements carried out by Reading and Leeds. The information on traffic movement and emissions will be coming from the modelling carried out at Leeds, supported by the field measurements of vehicle movement and traffic flow. Imperial College will host and manage the field campaign, and will take full responsibility for the measurements of exposure of bus users, pedestrians, cyclists and car drivers travelling through the study area.
