The Institute of Public Health in Ireland (IPH) aims to improve health on the island of Ireland by working to combat health inequalities and influence public policies in favour of health. The Institute promotes cooperation between Northern Ireland and the Republic of Ireland in public health research, training and policy advice. 

IPH acknowledges that health is influenced by a wide range of social determinants, including economic, environmental, social and biological factors. Transport is one of the key determinants of health and IPH welcomes the opportunity to comment on the Department for Regional Development (DRD), Regional Transportation Strategy (RTS) Review.
