In the Major era, transport increasingly came to be seen as a policy problem on three key levels: public health; congestion, and lifestyle, marking a significant change from the Thatcher period. Problem centred models of agenda setting argue that changes such as these are likely to have a negative effect on the policy image of an issue, and thus form an important element of any explanation of policy change. This chapter explores this hypothesis and evaluates the impact of each of these changes in the transport case.
