This report sets out the findings of a survey of all Directors of Public Health (DsPH) in England. The survey investigated the extent of collaboration between public health and transport teams within local government since public health teams moved into top-tier local authorities in April 2013. As well as analysis of survey results, the report includes a series of case studies exploring examples of good practice in more detail. The majority of DsPH responding to the survey said that there had been an improvement in the extent of their team’s collaboration with transport planning colleagues since the move to local government. Most placed a medium to high priority to on the health impacts of road transport in their work programme; had had the opportunity to engage with the development of local transport plans; and had participated in jointly funded projects and data sharing with transport colleagues. DsPH identified a number of barriers to further joint working, but there were also numerous examples of good practice. The research was conducted for pteg by public health and transport specialist, Dr Adrian Davis.
