This research project would aim to develop a Primer or Guidance document to help agencies tasked with managing infrastructure (including pavement and bridges) to assess their current data, data collection processes, and data needs to best position them to be able to take advantage of burgeoning artificial intelligence techniques to develop increasingly accurate predictive models regarding their infrastructure.
The quality of data is extremely important – “garbage in, garbage out” - and quality of data in terms of accuracy and precision is already getting much needed attention. However, while many agencies are actively improving collection of accurate and more data, collection the right quality data for accurate and precise prediction requires an additional level of scrutiny.
Collection of more accurate and precise data will undoubtably increase the accuracy of predictions, accurate predictive modeling also relies on understanding the underlying variables that affect the predictions. For example, variables that might affect the structural deterioration (for instance in the next time period) of an infrastructure element such as a pavement management section, might include:
- Structure information such as layer thicknesses and materials
- Environmental conditions such as temperature means and variation, rainfall etc.
- Load information such as traffic and truck traffic
- Current condition such as current cracking, rutting and roughness information
- Current condition such as layer properties and structural strength
- Information on previous maintenance, rehabilitation and reconstruction actions
Similar attributes would be considered significant variables for deterioration prediction in bridges, and this would also apply to many other non-bridge, non-pavement types of infrastructure assets.
Statistical analysis of this type of data for predictive analysis purposes is not new and Analysis of Variance (ANOVA) techniques have been used in this area for decades. However, with the advent of automated data collection techniques and with the quantity of available data growing at a considerable rate (so called ‘Big Data’), various types of AI such as artificial neural networks (ANNs) and deep learning techniques, are beginning to supersede some of these traditional statistical techniques. The ‘training’ portions of these techniques will require accurate and repeatable data as well as information on significant variables.
In addition, one the most valuable aspects of AI is the ability these types of techniques to continuously learn and improve. In this respect, it is again very important for agencies to understand how this learning could be accomplished, not just initially but continuously over time, using processes that involve continuous updates (e.g. through crowd sourcing). Agencies would therefore benefit considerably by having guidance available to help them set up their data capture and governance techniques to best benefit from AI modeling, training and continuous learning in the future.
Ideally, an agency would collect data that has the necessary attributes to facilitate an AI analysis and have processes in place that would allow continuous learning such that predictive modeling for the agency would continue to be trained and improved as the AI continued to learn. The current reality is such that condition data that is being collected may not be easily utilized in an AI analysis. The consequence is that the complicated decision-making process that highway agency executives depend upon may not be producing the level of accuracy in condition and funding projections that is required to make funding decisions in their investment strategies.

AI is coming – are we ready? With the MAP-21/FAST Act legislation, and the renewed emphasis on Transportation Asset Management Plans (TAMPs), projections made by management systems will come under increasing scrutiny as agency executive leadership is asked to make large scale funding decisions based on these projections. This scrutiny as well as the inherent complications in predictive modeling of asset deterioration, presents an opportunity for the use of Artificial Intelligence (AI) in this type of analysis.
AI is becoming ubiquitous in the realm of automation and pattern recognition and shows promise in improving predictive modeling for infrastructure managed by highway agencies. Because data collected over time is especially valuable for deterioration modeling, it is very important for agencies to start collecting the right data, and putting in place the right quality control, as early as possible so that this data is ready for immediate use as more research into AI techniques for predictive modeling is conducted.

Develop Approaches for Corridor Planning and Allocation
• Asset conditions are typically determined currently in separate silos - leading to asset treatments that are applied on varied schedules by asset (pavement, bridges, culverts) even over the same corridor.
• Significant resources may be misallocated on treatments applied at the wrong time due to lack of coordinated corridor planning.
• Corridor planning can organize the asset treatments — while also looking at environmental issues, congestion, and safety
• There may be other issues such as operation needs in a corridor as well.
o “Project delivery” can be achieved more efficiently because projects are organized into a corridor delivery strategy. Projects can be peeled off as funding is available
o Public can be engaged all at once instead of multiple times for multiple projects.
o Minimize contractor costs
Develop guidance on an asset management corridor planning process to prioritize and schedule project delivery for cost effectiveness while also considering mobility/accessibility issues, drainage, and more.
• Conduct a review and evaluation of existing agency corridor planning processes with respect to transportation asset management

Support Data Governance Implementation
• Recent NCHRP research products have documented data governance techniques and provided tools for agencies to assess their current data governance practices and identify strategies for improvement.
• NCHRP 08-115 (publication pending) included data governance as one of several foundational activities for improving use of data and information for transportation asset management. An NCHRP 20-44 proposal is in process to conduct pilot implementations of the guidance and assessment tool developed through that project, and produce supplemental guidance materials based on the pilots.
• Many DOTs are implementing data governance – through establishing governance bodies, defining data stewardship roles and putting standard processes in place. The AASHTO Data Management and Analytics Committee has established a Chief Data Officer (CDO) peer group to enable ongoing sharing of data governance practices.
• This project would build on the established base of prior and ongoing work on data governance. It would focus specifically on providing specific examples or models that can be applied to help advance asset management practice through data governance.
Provide support to implement the data governance practices and processes recommended through NCHRP 08-115, Guidebook for Data and Information Systems for Transportation Asset Management.
• Conduct outreach to identify implemented examples of transferable TAM-related data governance practices. These might include:
o role/responsibility descriptions for asset data stewards and asset management system owners,
o charters for TAM advisory bodies or governance groups,
o asset data-related policies or guidance documents,
o flowcharts or process descriptions for initiating new asset data collection efforts,
o work products related to establishment of data glossaries, catalogs or standards,
o asset data quality management plans or process descriptions, and
o asset data MOUs or agreements.
• Conduct a series of follow-up interviews to document the processes by which each of the identified examples were developed, and to seek permission for sharing the examples.
• Make the documented examples accessible (via the AASHTO TAM Portal and/or the AASHTO Data Management and Analytics Committee website)
• Conduct a webinar highlighting selected examples – featuring the DOT staff who were involved in their implementation.
• Recommend an ongoing mechanism for periodically refreshing the body of examples collected through this effort.

Develop Methods to Allow Agencies to Incorporate Quantitative Risk Assessment at Project and Network Level
Managing risk is a critical component of asset management. On a day-to-day basis transportation asset managers spend much of their time responding to or mitigating a large number of risks, which may range from external events that damage transportation infrastructure to unplanned changes to budget or workloads resulting from unexpected events. Various recent and on-going research efforts aim to improve approaches for risk management for transportation agencies. However, most of these efforts treat risk management as a high-level activity. Further research is needed to develop quantitative, repeatable approaches at the appropriate staff level, to assessing and identifying the highest priority risks transportation agencies face in managing physical assets. This project aims to develop such approaches to assess risks (e.g., financial, strategic, operational, political, environmental, technological, social justice risks) and incorporate them into life cycle analysis and planning efforts.
The objectives of this research are to:
• Generate risk identification techniques to determine high risk threats at project and network levels,
• Develop quantitative, repeatable approaches for assessing likelihood and consequences for these threats,
• Develop visual, interactive characterization methods (e.g., dashboards) to reflect an agency’s level of risk and the effectiveness of proposed mitigation actions,
• Allow risk and resilience to be on par with traditional performance measures.
High risk threats to be studied include, but are not limited to, extreme events (e.g., earthquakes, fires, hurricanes, avalanches, tornadoes), asset failure (structural and operational), financial, strategic, political, environmental (e.g., sea level rise, flooding), technological, and social justice risks.
The final deliverables could include guidebook with a spreadsheet or a framework for assessing high risk threats and incorporating the results into TAM efforts. The guidebook should feature a comprehensive review of existing literature and current practice. It should present a standard definition of resilience as well as step-by-step instructions to develop models, methods, and metrics for estimating resilience of highway systems to high risk threats. Pilot studies should be conducted with select agencies to test the guidance and calculation procedures.
The target audience for the research results is asset management and risk-management champions at state and local government transportation agencies. The results of this project will potentially empower these individuals in convincing other decision makers in these agencies to take actions that not only align with traditional performance management objectives but also that result in lower risk and higher resilience for the whole transportation system. The results of this project can also be effective in communicating the rationale behind risk-based decisions to the general public. Due to legal implications of identifying and documenting risks, the research and final product should include advice on how to protect the agency from litigation if they cannot implement a recommended action.
Risk assessment is at the core of implementing a risk-based asset management approach. Therefore, FHWA and AASHTO view this as a subject of great importance. In addition, risk management cuts across all areas of a state DOT’s business and just about any AASHTO Committee and any state DOT and local agency could realize benefits from these research results.

• Develop quantitative, repeatable approaches for assessing likelihood and consequences for these threats,
• Develop visual, interactive characterization methods (e.g., dashboards) to reflect an agency’s level of risk and the effectiveness of proposed mitigation actions,
• Allow risk and resilience to be on par with traditional performance measures.
High risk threats to be studied include, but are not limited to, extreme events (e.g., earthquakes, fires, hurricanes, avalanches, tornadoes), asset failure (structural and operational), financial, strategic, political, environmental (e.g., sea level rise, flooding), technological, and social justice risks.
The final deliverables could include guidebook with a spreadsheet or a framework for assessing high risk threats and incorporating the results into TAM efforts. The guidebook should feature a comprehensive review of existing literature and current practice. It should present a standard definition of resilience as well as step-by-step instructions to develop models, methods, and metrics for estimating resilience of highway systems to high risk threats. Pilot studies should be conducted with select agencies to test the guidance and calculation procedures.
Managing risk is a critical component of asset management. On a day-to-day basis transportation asset managers spend much of their time responding to or mitigating a large number of risks, which may range from external events that damage transportation infrastructure to unplanned changes to budget or workloads resulting from unexpected events. Various recent and on-going research efforts aim to improve approaches for risk management for transportation agencies. However, most of these efforts treat risk management as a high-level activity. Further research is needed to develop quantitative, repeatable approaches at the appropriate staff level, to assessing and identifying the highest priority risks transportation agencies face in managing physical assets. This project aims to develop such approaches to assess risks (e.g., financial, strategic, operational, political, environmental, technological, social justice risks) and incorporate them into life cycle analysis and planning efforts.
Literature Search Summary
Risk management has been studied quite extensively in the transportation sector. Risk management encompasses four major steps: Risk identification, risk assessment, risk mitigation, and continuous updating of results. Risk assessment focuses on determining the magnitude of risk, which is directly proportional to the likelihood and consequences of an event to occur. Risk assessment has been a major area of study in pavement and bridge management efforts. In recent decades, the focus has shifted from assessing risk in single networks towards more holistic risk assessment approaches.
Between 2012 and 2013, Federal Highway Administration (FHWA) published a five-part report series on Risk Based Asset Management. These reports focus on: (1) Overview of risk management, (2) Managing risk at different levels, (3) Strategic risk management (risks to agency objectives), (4) Managing risk to critical assets, and (5) Managing external threats such as climate change and extreme weather risks. These reports played an important role in introducing risk management concepts into asset management efforts. In 2016, American Association of State Highway and Transportation Officials (AASHTO) published the Guide for Enterprise Risk Management. In this Guide, risk management is defined as “the systematic application of policies, procedures, and practices to the identification and management of uncertainty or variability on achievement of agency objectives.” In addition, the Guide introduces four levels at which risks need to be managed: Strategic, Program, Project, and Activity levels. Enterprise Risk Management is defined as management of risks at all levels. Other research projects (recently completed, active, or pending) in this area include:
• NCHRP 08-113: Integrating Effective Transportation Performance, Risk, and Asset Management Practices
• NCHRP 08-118: Risk Assessment Techniques for Transportation Asset Management
• NCHRP 20-44(02): Implementation of the AASHTO Guide for Enterprise Risk Management
• NCHRP 20-123(04): Development of a Risk Management Strategic Plan and a Research Roadmap
• NCHRP 08-129: Incorporating Resilience Concepts and Strategies in Transportation Planning
• NCHRP 23-09: Scoping Study to Develop the Basis for a Highway Standard to Conduct an All-Hazards Risk and Resilience Analysis.
Managing risk at program (or network) and project levels is particularly important to achieve desired performance levels and to improve resilience of a transportation system. While existing research efforts in this area are highly significant, there is a need for developing more practical and repeatable risk assessment calculation methods for project and network level risks. This proposed study will build on these recent efforts, particularly NCHRP 23-09, and serve as the next phase in risk assessment and management.
Objectives
The objectives of this research are to:
• Generate risk identification techniques to determine high risk threats at project and network levels,
• Develop quantitative, repeatable approaches for assessing likelihood and consequences for these threats,
• Develop visual, interactive characterization methods (e.g., dashboards) to reflect an agency’s level of risk and the effectiveness of proposed mitigation actions,
• Allow risk and resilience to be on par with traditional performance measures.
High risk threats to be studied include, but are not limited to, extreme events (e.g., earthquakes, fires, hurricanes, avalanches, tornadoes), asset failure (structural and operational), financial, strategic, political, environmental (e.g., sea level rise, flooding), technological, and social justice risks.
The final deliverables could include guidebook with a spreadsheet or a framework for assessing high risk threats and incorporating the results into TAM efforts. The guidebook should feature a comprehensive review of existing literature and current practice. It should present a standard definition of resilience as well as step-by-step instructions to develop models, methods, and metrics for estimating resilience of highway systems to high risk threats. Pilot studies should be conducted with select agencies to test the guidance and calculation procedures.
Urgency and Potential Benefits
While existing reporting mechanisms allow agencies to see the parts of their network that are in good and poor condition, risks associated with different threats and the impact of failure are not reported as an explicit performance measure. Competing design documents, financial implications, legal concerns, maintenance practices, focus on building new capacity rather than managing existing infrastructure, and other factors that affect decision making procedures may counter-act risk-based TAM practices. Issues related to social justice and equity, and consequences of failures make risk-based TAM even more important. Creating harmony in the TAM decision making space in consideration of risk and resilience represents an urgent need. A practical, quantitative, and repeatable risk assessment process could play a major role in addressing this need.
Notes and Considerations
The target audience for the research results is asset management and risk-management champions at state and local government transportation agencies. The results of this project will potentially empower these individuals in convincing other decision makers in these agencies to take actions that not only align with traditional performance management objectives but also that result in lower risk and higher resilience for the whole transportation system. The results of this project can also be effective in communicating the rationale behind risk-based decisions to the general public. Due to legal implications of identifying and documenting risks, the research and final product should include advice on how to protect the agency from litigation if they cannot implement a recommended action.
Risk assessment is at the core of implementing a risk-based asset management approach. Therefore, FHWA and AASHTO view this as a subject of great importance. In addition, risk management cuts across all areas of a state DOT’s business and just about any AASHTO Committee and any state DOT and local agency could realize benefits from these research results.

Evaluate Federal Measures and Metrics for Pavements
The Moving Ahead for Progress in the 21st Century (MAP-21) transportation bill established federal regulations that require each State Department of Transportation (DOT) to develop a Transportation Asset Management Plan (TAMP), and implement Performance Management. These regulations require all DOTs to utilize nationally defined performance measures for pavements on the National Highway System (NHS). These nationally defined performance measures (referred as PM2 hereafter) are aimed at providing nationally consistent metrics for DOTs to measure condition, establish targets, assess progress toward targets, and report on condition and performance. Furthermore, Federal measures provide the Federal Highway Administration (FHWA) the ability to better communicate a national performance story and to more reliably assess the impacts of Federal funding investments.
State DOTs are expected to use the information and data generated from these Federal measures to inform their transportation planning and programming decisions. However, State DOTs are finding discrepancies between pavement conditions from PM2 measures as compared to their internal, state-developed measures. This discrepancy hampers the adoption of the PM2 pavement measures as the primary input into condition summary reporting and pavement investment prioritization and decision-making. In other words, State DOTs do not have confidence in the Federal measures, primarily because these measures cannot be used to inform decision-making processes such as investment decisions. Furthermore, the resulting differences between state metric-determined and federal metric-determined network conditions creates confusion among the public, senior executive staff, and legislative bodies, along with non-DOT owners of NHS assets.
As mentioned before, FHWA needs to collect consistent Federal measures across all State DOTs to assess the impact of Federal funding investment at the national level. However, State DOTs have been collecting pavement performance data for decades and used this data to inform their pavement management systems and processes to address specific needs. Typically, the data collection processes cover state-owned pavements and not only NHS pavements, which brings another layer of inconsistency. For this reason, there is a need for more flexible metrics that can be aligned to performance measures currently used by State DOTs and support decision-making processes such as investment decisions.
The objective of this research is to:
1. Evaluate current federal pavement condition measures (Ride Quality, Rutting, Faulting, and Cracking), performance thresholds, and overall performance measure with respect to:
a. Consistency – across various pavement types, network designations, and lane configurations
b. Usefulness – in network-level pavement condition summary and asset management decision-making, prioritization, and forecasts; and
c. Alignment – with state established pavement condition metrics
2. Provide recommendations to improve existing measures and/or identify metrics that better reflect pavement failure mechanisms and enhance decision-making taking into account not
only the assessment of current and future condition but also their implications in economic analyses of long-term maintenance and rehabilitation. Evaluate pavement leading indicators as an alternative to the current version of the PM2.
3. Identify and address in detail specific challenges for each condition measure (Ride Quality, Rutting, Faulting, and Cracking) for consistency, including thresholds. For example, determine if wheel path cracking considerations could be revised to provide more consistent results across pavement types (e.g. composite, concrete) and pavement widths (e.g. <12 ft.)
4. Evaluate structural capacity indicators for potential consideration as a Federal measure.
Proposed research activities include:
1. Conduct outreach interviews to State DOTs and evaluate DOT publications (e.g TAMPs) to:
a. Capture current uses for federal and state-specific pavement condition metrics and their relative strengths and weakness with respect to identified network-level uses
b. Quantify the extent of the State DOTs’ differences with current federal pavement metrics
c. Capture alternative procedures states are using to determine and communicate pavement condition and/or failure as well as network-level decision-making
d. Source State DOT condition data sets, including corresponding state and federal ratings and network-level pavement maintenance recommendations
2. Conduct a comparative analysis between state and federal measures and determine the ability to utilize federal measures to replicate network-level decisions.
3. Evaluate alternative methods of federal measure with best practices of state measures to develop a list of alternative methods that could be used for pavement management measures and meet both State and Federal needs.
4. Provide summary and comparison of current vs. alternative methods with respect to evaluation criteria at national and individual state levels
5. Provide guidance on how to enhance the utility of current federal measures and/or condition thresholds and recommend revisions in a format useful to adoption into the HPMS Field Manual
Desired products include:
• Evaluation of federal measure with respect to consistency, usefulness, and alignment
• Guidance on how to increase the utility of current metrics and/or thresholds
• Recommendations for revised pavement condition metrics and/or thresholds
• Recommendations for updated HPMS Field Manual
This topic is of significant interest to AASHTO, TRB, and the DOTs, having ranked third amongst potential NCHRP topics in the recent TAM Research Prioritization conducted as part of the 2020 Mega Meeting of the AASHTO Subcommittee on Asset Management, in cooperation with the TRB Asset Management Committee (AJE30).

Because DOTs are only two years into implementing the pavement performance measures and metrics, the urgency is great to make sure the measures in use are as meaningful, consistent and implementable as possible. Currently, the performance measures have not achieved widespread use as the primary performance criteria for decision-making, leading to two sets of metrics being used by many agencies. In addition, DOTs must make performance predictions and justifications based on the federal performance measures. Making any changes to the measures as soon as possible will allow DOTs to build up datasets on which to base predictions of future performance.
Potential benefits to improving the federal pavement performance measures and metrics include:
• Metrics that better define pavement failure mechanisms and therefore condition
• Metrics that result in more consistent results across pavement types and pavement widths
• Broader adoption of the measures by DOTs as part of decision-making criteria
• Less confusion among the public, senior executive staff, and legislative bodies, along with non-DOT owners of NHS assets by having one set of metrics instead of two (federal and state-specific)

Causes and Effects of Transportation Data Variability
• State departments of transportation (DOTs) and metropolitan planning organizations (MPOs) across the United States are required to establish performance targets as part of their asset management efforts. The target- setting requirements for transportation performance management (PM2) of pavement and bridge condition generally require agencies to consider three factors; the measured condition of the assets, expected deterioration over time and project level accomplishments. The measured condition of the asset is the ultimate measure of progress and an effective way for agencies to demonstrate that they are making progress as required by federal regulations.
• Research assessing the consistency of National Bridge Inventory (NBI) condition metrics has found variability between individual inspectors when inspecting “control bridges” for study. In other words, there is the potential for any given bridge inspector to assess the current condition of same bridge differently. This variability means that the conditions of bridge could improve in the absence of a project just by having a different inspector interpret the field condition differently. A similar potential exists for pavement condition assessments. This demonstrates the potential inconsistencies due to human interaction, but the same could be true of technologies if applied or calibrated differently across agencies.
• Pavement and bridge conditions rely on assessment methods that are subject to variability from one assessment to the next and from one assessor or one technology utilization to the next. This variability may occur in the absence of projects or significant field deterioration. This research project would attempt to evaluate the impact of condition assessment variability on agency wide target setting required for asset management.
The outcome from this effort will benefit quality assurance (QA) methods for data collection and inspection efforts, quantify the variability and sensitivity in target setting for DOTs, and help budget planning for asset inconsistencies.
• Review and summarize existing published research related to the
• consistency of field-assessed pavement and bridges whether based on human interaction or applied automation, and include a review of training programs associated with human and automated assessments. Additionally, review research on the impact of assessed condition variability on target setting.
• Review NBI and Highway Pavement Monitoring System (HPMS) submittals over multiple years to identify examples of spontaneous improvement or rapidly changing conditions from one assessment to the next and assess the sensitivity of condition assessment variability on target setting in transportation asset management.
• Develop a methodology and guidance manual to define the uncertainty associated with variability in condition assessment when setting asset management targets and provide means to rectify inconsistencies in the assessments when they appear.
• According to FHWA’s transportation performance management (TPM), the purpose of transportation asset management is to provide the most efficient investment of funds. This decision-making is being based on data that is subject to variability. Understanding and quantifying (if possible) the impact of data variability will allow federal, state, and local agencies to recognize the importance of data quality and how it might impact their ability to deliver projects and strive for the national transportation goals. The outcomes and benefits are:
o Showcase the importance of quality and consistent data collection methodology
o Tie the data to decision making and funding
o Evaluate the impact of condition assessment variability on agency wide target setting
o Highlight progress on 490.319(c) Data Quality Management Program
o Provide states and federal a baseline expectation for changes in annual variability in measures, failure to reach targets, and/or best practices to avoid data quality issues.
• Since the performance measures are consistently tied to specific data inputs, each state could use this research to understand the potential volatility in target setting and performance measures. The summary of best practices and pitfalls will also allow transportation agencies and vendors to improve inspection protocol. Testing of the data should be a part of the research, with a few select agencies comparing potentially the same data in a single year across multiple sources or reviewing the historic trends of individual data pints to highlight inconsistencies and the impact of those inconsistencies to overall measures and targets.
• This research would best be shared in an open forum or webinar so all agencies and consultants tasked with data management can obtain the information. The AASHTO Performance Management Committee should be interested in supporting this research to ensure that the performance measures produced by transportation agencies are of the highest quality.

Background/Description
• State departments of transportation (DOTs) and metropolitan planning organizations (MPOs) across the United States are required to establish performance targets as part of their asset management efforts. The target- setting requirements for transportation performance management (PM2) of pavement and bridge condition generally require agencies to consider three factors; the measured condition of the assets, expected deterioration over time and project level accomplishments. The measured condition of the asset is the ultimate measure of progress and an effective way for agencies to demonstrate that they are making progress as required by federal regulations.
• Research assessing the consistency of National Bridge Inventory (NBI) condition metrics has found variability between individual inspectors when inspecting “control bridges” for study. In other words, there is the potential for any given bridge inspector to assess the current condition of same bridge differently. This variability means that the conditions of bridge could improve in the absence of a project just by having a different inspector interpret the field condition differently. A similar potential exists for pavement condition assessments. This demonstrates the potential inconsistencies due to human interaction, but the same could be true of technologies if applied or calibrated differently across agencies.
