Integrated Strategies for Managing Excessive Travel Speed to Improve Safety Performance

The objective of this research is to develop a guide for state departments of transportation (DOTs), transportation agencies, and their partners to institutionalize ISSMF in their policies, practices, and interventions to improve safety performance. At a minimum, the research shall cover: (1) Summary and lessons learned related to agency speed management approaches and policies, including impacts on traditionally underserved communities;  (2) Behavioral, cultural, and human factor determinants of speed choice; (3) Travel speed management countermeasures that are useful in different contexts;  (4) Holistic speed management schemes suitable for the different stages (planning, design, construction, maintenance, and rehabilitation) of a project’s lifecycle;  (5) Implementation framework to identify critical steps and partners for high-quality implementation; and (6) Partner and stakeholder engagement and input that are incorporated into a unified, adaptable framework for managing excessive travel speed.
