The transportation profession is in the midst of game-changing movement in the planning and design of safe and efficient roadways. Local and state agencies are shifting towards performance-based, data-driven decision making and solutions that require a transparent assessment of trade-offs between performance measures—namely safety, operations, environmental impacts and life-cycle cost. Flexibility is not only needed; it is a necessity for designing roadways for all modes. The webinar will provide an overview of national guidance and highlight implementation by States and local agencies of flexible lane widths on projects.
