Understand the role of KM in fostering advancements within specific DOT business functions. Provide an in-depth, “on the ground” understanding of current processes for knowledge creation, sharing, and application as part of different DOT business areas (e.g., safety, asset management, resilience planning, system operations) and situations (e.g., response to new legislative mandates; new technology adoption). Use results to inform development of a KM implementation framework and tailored guidance on KM implementation for different DOT functions.

Research Activities:

  1. Conduct a series of structured interviews at DOTs covering the following topics:
    1. Learning the Ropes: how new employees learn what they need to be successful
    2. Passing the Torch: how senior employees share what their successors need to know
    3. Continuous Improvement: how teams learn about how to do things better
    4. Connecting with Colleagues: how and when staff consult with others in the agency that are playing a similar role (e.g., personnel in different field offices)
    5. Making It Happen: information capture, sharing, disposition to support currency of practice, collaboration, efficiency, knowledge transfer, and innovation
  2. Document interview findings on current practices for knowledge creation/capture, sharing, discovery and application as part of different DOT business areas and situations.

  1. Identify a group of DOTs interested in receiving implementation support.
  2. Plan and scope the support activities with points of contact at each agency.
  3. Conduct a series of facilitated sessions with each agency to provide support.
  4. Document the results of the effort.

F4. Advancing Knowledge Representation Methods for Transportation Agencies—Pilot Applications

Objectives:

Demonstrate practical applications of knowledge representation methods. Work with a set of volunteer agencies to support pilot projects demonstrating advances in knowledge representation methods. Document their results and suggest ways to facilitate adoption of the most successful pilot techniques.

Research Activities:

  1. Identify a group of DOTs interested in pursuing pilots.
  2. Plan and scope the pilot activities with points of contact at each agency.
  3. Carry out and document the pilots.

  2. Plan and scope the pilot activities with points of contact at each agency.
  3. Carry out and document the pilots.

F6. Supporting Implementation of Learning Culture Assessment and Improvement

Objectives:

Support Implementation of Research on Improving Learning Cultures. Work with a group of DOTs to support implementation of learning culture assessment and improvement guidance, based on the results of a prior NCHRP project.

Research Activities:

  1. Identify a group of DOTs interested in receiving implementation support.
  2. Plan and scope the support activities with points of contact at each agency.
  3. Conduct a series of facilitated sessions with each agency to provide support.
  4. Document the results of the effort.

F7. AKS – Pilot Application

Objectives:

Demonstrate the AKS concept with one or more DOTs. Work with a set of volunteer agencies to support pilot projects demonstrating creation of an AKS. Document their results and suggest ways to facilitate adoption of the most successful pilot techniques.

Research Activities:

  1. Identify a group of DOTs interested in pursuing pilots.
  2. Plan and scope the pilot activities with points of contact at each agency.
  3. Carry out and document the pilots.
