Abstract for: The policymaking dynamics of adopting speed limit reductions: a key information interview based system mapping effort
Public health is a product of a broad range of factors, and should be targeted by multiple sectors. Transport policy is such opportunity to integrate a health perspective and promote public health. Whether or not speed limit reductions are enacted and implemented, is a matter of political decision making, but the specific policy dynamics that precede these decisions are not well understood. The trend across European countries is to introduce 20mph zones, however, not all cases are evenly successful. Understanding the policy dynamics that precede decision making, and where public health researchers may support in reaching health promoting policies, can help in identifying facilitators of policy enactment. Therefore, we aim to 1)identify the dynamics and factors involved in 30km/h decision making on the local level, and the role of dynamics and factors as being facilitative and or obstructive, as well as 2)to understand the role of public health evidence in this process and how it can be a facilitator in policy enactment. We perform key informant interviews in stakeholders involved with policy changes to 20mph speed limits in European cities, to identify themes in policy enactment and decision making of 20mph policy changes, and the role for public health researchers.
