While terms like "Complete Streets" and the "Safe System Approach" are becoming the standard for modern transportation project development, their real meaning lies in their implementation. This presentation delves into how the New Hampshire Department of Transportation (DOT) has moved beyond mere adoption to integrate these concepts into the very fabric of the agency. Success hinges on leadership commitment and the ability to translate ideas into actionable strategies—from project inception and design to construction, maintenance, and operation. Attendees will gain insights from the challenges faced and lessons learned during this, offering a roadmap for fostering a culture that prioritizes safety in transportation planning and execution.
