The KM Research Roadmap is based on a review of current and pending research as well as stakeholder needs as of 2022–2023. KM RNs will shift over time, as research projects are completed, as transportation agencies mature their practices, and as technologies advance. In particular, we are likely to see rapid advancements and adoption of AI tools and techniques for knowledge discovery and delivery in the coming years. As transportation agencies continue to put these capabilities in place, new RNs will emerge.
This Plan describes a sustainable process for keeping the KM Research Roadmap updated through periodic review and revision. It suggests a set of steps to follow for the update process, identifies the groups who will lead this process, and describes the prototype research management system developed to maintain roadmap information.
The AASHTO Committee on Knowledge Management’s Research Subcommittee (AASHTO CKM-RS) is the logical group to own and manage the roadmap update process. The TRB IKM Committee should play a support role given their scope and broad membership representation across public, private and academic sectors.
Monthly Updates. The KM Research Roadmap can be updated on a continuous basis as new RNs are identified, RPSs are drafted and revised, and KM-related research projects are funded and completed. The AASHTO CKM-RS can add a standing agenda item to its monthly meetings to identify any changes to needs, RPSs, and projects and assign responsibility for making these updates.
Bi-Annual Updates. Every other year, the KM Research Roadmap should be reviewed in a comprehensive fashion, with a focus on updating the RNs and unfunded RPSs to reflect new concerns and needs that have emerged since the last update cycle. These bi-annual updates should be timed to support the research funding cycle. This bi-annual update process should be jointly managed by the AASHTO CKM-RS and the TRB IKM Committee.
The bi-annual update process should involve the following steps:
This process should take between 2-3 months to complete. Ideally it should be timed to be wrapped up by September so that the AASHTO CKM-RC can use the results to recommend projects for the annual NCHRP cycle (RPSs are due November 1st.)
Following the bi-annual update cycle, AASHTO CKM and TRB IKM should carry out the recommended cyclical communications activities in the KM Research Roadmap Communication Plan to remind stakeholders of the roadmap and sustain interest and activity in funding and collaborating on KM-related research.
A research roadmap for KM RRM has been created through NCHRP Project 23-14 and is available at https://apps.trb.org/cmsfeed/TRBNetProjectDisplay.asp?ProjectID=4999. In order to facilitate ongoing updates to the roadmap to keep it fresh and maximize the reach and impact of the roadmap, the project has also produced a functional prototype of a web-based research management system (KM RMS).
The KM RMS is a Django/React web application with a Postgres (SQL) database, deployed on Heroku (Platform as a Service Provider). It provides the following capabilities:
All users (no login needed) can browse information, submit suggestions for new or modified RNs and RPSs and submit suggestions for KM-related projects to be included in the system.
Only people with assigned Edit privileges can modify the information in the KM RMS. The KM RMS Administrator is responsible for assigning Edit privileges as needed.
The KM RMS has three major tables: RNs, RPSs, and Research Projects.
RNs describe a research concept. Research concepts are “raw” needs that can be incorporated into RPSs (see below). The KM RMS RNs have been populated with the needs identified in the KM RRM. Each record in the RNs table has the following data elements:
RPSs are fully developed proposals for research projects to be considered for funding. Data elements are:
Research Projects are KM-related research projects that are pending (i.e., funded but not yet active), underway or completed. The list of research projects was populated based on the KM literature review conducted for NCHRP Project 23-14. This literature review focused on projects completed since 2010, though a few earlier projects were included. Data elements for research projects are:
Figure F-1 shows the relationships across the three tables.
RPSs can be associated with one or more RNs that are covered within their scope.
RNs, RPSs, and Research Projects (RPs) are tagged with KM Motivations, KM Processes, and Research Tracks. RNs are also assigned to an RN Category. Values for these tags are shown below.
RPSs can be associated with one or more RNs that are covered within their scope.
When an RPS is approved for funding, it can be associated with a RP. Sometimes RPs are funded that combine multiple RPSs. Therefore, the database allows for a many-to-one relationship between RPSs and RPs.
Note: There is no automated way to create an RP from an RPS—RPs must be added manually.
These indicate the motivations for KM implementation addressed by the need, problem statement or project:
These indicate the types of KM processes or techniques that are addressed by the need, problem statement or project:
The research tracks are the organizing structure for the RPSs in the roadmap. They are also used to tag RNs and research projects to allow for filtering of all items based on research track. Three tracks were defined. In addition, an “Other” category was included to tag historical research projects that do not fit into the three main tracks.
RN categories are the five categories of RN that were identified through the KM RRM literature review:

In the above example (Research Needs and Problem Statements are selected), if you want to see Problem Statements and Research Projects, first click on Research Needs to de-select it. Then, click on Research Projects.

This expands the screen to show the available filter options. Four options will always be available on the left side of the screen: Research Tracks, KM Motivations, KM Processes and Funding Programs. If you select any of these options, they will apply to all of the active tables.
If the Research Needs table is selected, the Need Status and Need Category will be active.
If the Problem Statements table is selected, the Statement Status will be active.
If the Research Project table is selected, the Project Status will be active.



A window will open showing details for your selected item.

Anyone can suggest changes to the KM Research Roadmap. Changes can include adding new Research Needs, Problem Statements, or Projects OR modifying information for an existing Research Need, Problem Statement, or Project. All suggestions are sent to the KM RMS Administrator.


You can also suggest a change to any existing roadmap information – for example:
To suggest an update to a particular record for a Research Need, Problem Statement, or Project:

The procedures in this section can be used by individuals who have been assigned Edit privileges to update information about Research Needs, Problem Statements, and Projects.
Updates to the RMS will be needed in the following situations:
For the above activities, see the section below for: Updating an Existing Research Need, Problem Statement, or Project.
For the above activities, see the section below for: Adding a New Research Need, Problem Statement, or Project.









Then, you can unselect and select RNs from the list that appears. When you have completed your selections, just click anywhere outside of the active window to return to the edit form.

Then, you can unselect and select one or more RPSs from the list that appears.

When you have completed your selections, just click anywhere outside of the active window to return to the edit form.
