About the research
The project will gather information about factors that encourage speeding, speed reduction strategies, and how agencies holistically address speed management. This will be accomplished through a formal literature review and a survey of agencies, followed by several workshops that will engage diverse teams to generate insights into factors and behaviors that encourage speeding. Building on this, the research team will first develop an outline and then fully develop an Integrated Strategies for Speed Management Framework (ISSMF) guidebook. It is anticipated that the ISSMF will be patterned as a guidebook to assist state Departments of Transportation (DOTs), transportation agencies, and their partners in accessing tools and strategies to manage excessive speeds. The guidebook will also provide strategies to overcome institutional barriers in various communities with the help of strategic partners (e.g., county public health departments, local hospitals, local news media, enforcement,
and judication).
The guidebook will provide developed, integrated strategies for the speed management framework. These strategies will be flexible enough to deal with and address issues such as global pandemics and any siloed funding of the disconnected parts of the system, as well as provide an increased awareness of social inequities in transportation safety and access to transportation, along with technological breakthroughs. The guidebook will include development of speed modification factors (SMF) when sufficient information is available for a particular countermeasure. SMFs will be developed using a systematic review and meta-analysis of existing studies.
