Transportation Asset Management Gap Analysis Tool

  Project Data
Funds: $150,000
Staff Responsibility: Andrew Lemer
Research Agency: Applied Pavement Technologies
Principal Investigator: Ms. Kathryn A. Zimmerman
Effective Date: 5/7/2013
Completion Date: 9/15/2014
Comments: Research in progress (Draft final products received)


The objective of this research is to develop a TAM gap analysis tool for state DOT and local transportation practitioners to facilitate their implementation of TAM. The tool should be formulated as a spreadsheet application based on the prototype presented in TAM, Volume 2 and incorporate refinements responsive to (a) requirements of MAP-21 and subsequent FHWA rulemaking and (b) institutional and technical characteristics of U.S. transportation system management practices. 


Review the process for gap analysis (and the associated prototype spreadsheet-based tool) described in TAM, Volume 2 and other relevant literature (e.g., MAP-21 and corresponding rulemaking) to refine the process and develop functional requirements for the gap analysis tool to be implemented in Phase II. The review should cover topics including, but not limited to: (a) assessment of the validity of the topics (key TAM assessment areas); (b) linking the gap analysis process to the agency’s effort to develop a TAM plan; (c) relationship to MAP-21; (d) additional topics to be added/expanded; and (e) topics to be removed/de-emphasized. The gap analysis tool should follow the work flow as depicted in the illustration shown in Section of the TAM, Volume 2: Gap Analysis Tool. Key assessment areas should include, but not be limited to: (a) policy guidance; (b) planning and programming; (c) program delivery; (d) information and analysis; (e) lifecycle and risk management; and (f) legislative compliance. The results of the gap analysis should be structured to assist practitioners by providing inputs to identify and prioritize areas for improvement and developing a performance-based asset management plan as suggested in TAM, Volume 2.The deliverables should include a Phase I interim report providing: (a) a working definition and process for gap analysis; (b) functional and technical requirements for the tool; (c) glossary of terms used; and (d) an updated work plan for Phase II, including identification of final deliverables and formats.

Implement the updated Phase II work plan and prepare the following deliverables: (a) guidelines to define and describe the process of conducting TAM gap analysis; (b) an integrated spreadsheet-based tool that accompanies the guidelines; (c) an executive summary that outlines the application of the research results; (d) a final report that documents the entire project, incorporating all other specified deliverable products of the research; and (e) a webinar presentation describing the gap analysis tool and providing instructions for using the tool. The guidelines should be written in a user friendly manner along with instructions for the use of the tool developed. The tool developed should be (a) scalable in terms of programs and maturity levels; (b) customizable in terms of adding or deleting key assessment areas and individual questions; (c) user friendly for practitioners with varying expertise; (d) readily accessible for different levels of analysis; (e) applicable by functional area (e.g., policy guidance, planning and programming, etc.); (f) accompanied by metadata; (g) structured and programmed for agency wide use; (h) suitable for incorporation by AASHTO into the TAM Implementation Guide; (i) tested with a sample of state DOT practitioners for practical usability; and (j) accompanied by reporting functions that include appropriate visual and text outputs that could be used as inputs by practitioners and decisionmakers for identifying prioritized areas of improvement to address gaps and develop an TAM Improvement plan as suggested in TAM, Volume 2.
STATUS: Research is underway on Phase I.  A Phase I draft report was received in September 2013 and the draft final products (with associated deliverables) for the project were received in April 2014.  Final products are expected by August 2014.
