Transportation Asset Management (TAM)

Transportation Asset Management (TAM) is an integrated, comprehensive and strategic approach to cost effectively manage Georgia’s assets and meet its transportation needs. TAM’s key strength is that it is data‐driven, and decisions can be supported by the data it uses and generates, as well as by sound engineering judgment. The TAM process has enabled GDOT to move away from the traditional “worst‐first” to “most at risk first” approach when managing its infrastructure and applying preservation activities.

Transportation Asset Management Plan

The Transportation Asset Management Plan (TAMP) is a federally required document that describes Georgia’s current bridge (bridge culverts) and pavement asset management processes for improving and preserving the condition of the National Highway System (NHS). The scope of this TAMP includes pavements and bridges (bridge Culverts) on the entire NHS, comprised of approximately 7,200 miles of roadway within the State which includes interstates, state routes and local roads as well as 4,300 structures of both bridges and bridge culverts.

Transportation Performance Management (TPM)

FHWA defines Transportation Performance Management (TPM) as a strategic approach that uses system information to make investment and policy decisions to achieve national performance goals. The national performance goals cover the following areas:

Safety
Infrastructure condition
Congestion reduction
System reliability
Freight movement and economic vitality
Environmental sustainability
Reduced project delivery delays

Utilizing Transportation Performance Management

TPM helps State DOTs to both monitor and improve their asset life-cycle performance. Utilizing performance data to supplement their decision-making processes, State DOTs can better demonstrate how they manage their transportation infrastructure and make resource allocation decisions.

Benefits of TPM

Optimized investments of Federal transportation funds
Alignment of State DOTs performance with national transportation goals
Increased accountability and transparency
Improved decision-making through performance-based planning and programming

Performance Measures and Targets

The State DOTs and MPOs are required to collect data and submit their performance measures and targets for Safety, Bridge and Pavement Conditions, and System Performance, Freight, and Congestion Mitigation and Air Quality (CMAQ). The FHWAs requirements for each of these measure areas are formulated in the Final Rules.

Additionally, the requirements for the performance measures Final Rules were formulated to aid States better carry out the pre-established goals of the national highway programs. The national highway programs include:

FHWA Dashboard

Georgia DOT is compliant with the PM Final Rules requirements and has been reporting the performance measures to FHWA.

The figure below depicts the reporting timeline for all States to submit their performance measures to FHWA.

Statewide Transportation Improvement Program

The Statewide Transportation Improvement Program (STIP), is a four-year transportation and capital improvements program. The STIP lists federally-funded transportation projects that are located outside Metropolitan Planning Organization (MPO) boundaries. Each MPO develops its own Transportation Improvement Program (TIP). The TIPs are included in the STIP by reference without modification once approved by the MPO and the Governor, or his designee. Projects include highway, bridge, public transit, bike, pedestrian, railroad, and other improvements.

Safety [PM1]

FHWAs Safety Performance Measures Final Rule is aligned with the Highway Safety Improvement Program (HSIP) as it uses safety performance measures to carry out its requirements. The safety performance measures evaluate the number of motorized and non-motorized incidents involving fatalities and serious injuries on all public roads. The performance measures are as follows:

Number of Fatalities
Rate of Fatalities per 100 million Vehicle Miles Traveled (VMT)
Number of Serious Injuries
Rate of Serious Injuries per 100 million VMT
Number of Non-motorized Fatalities and Non-motorized Serious Injuries

Infrastructure Condition [PM2]

FHWAs Pavement and Bridge Condition Final Rule is aligned with the National Highway Performance Program (NHPP) and aids State DOTs to better carry out the programs requirements. The performance measures that are used to evaluate the pavement and bridge conditions are as follows:

Percentage of National Highway System (NHS) Bridges by Deck Area in Good Condition
Percentage of National Highway System (NHS) Bridges by Deck Area in Poor Condition
Percentage of Interstate Pavements in Good Condition
Percentage of Interstate Pavements in Poor Condition
Percentage of Non-Interstate NHS Pavements in Good Condition
Percentage of Non-Interstate NHS Pavements in Poor Condition

System Performance, Freight, and CMAQ [PM3]

FHWAs System Performance, Freight and CMAQ Final rule aligns with the National Highway Freight Program (NHFP) and Congestion Mitigation and Air Quality (CMAQ) Improvement Program. This rule uses performance measures, as listed below, to evaluate the travel-time reliability of the national highway system and the time reliability for freight movement on the interstate system. The rule also proposes the measures to evaluate traffic congestion and the On-Road Mobile Source Emissions. The performance measures used to evaluate the system performance, freight, and CMAQ are as follows:

Percent of Person-Miles Traveled on the Interstate that are Reliable
Percent of Person-Miles Traveled on the Non-Interstate National Highway System that are Reliable
Truck Travel Time Reliability Index
Annual Hours of Peak Hour Excessive Delay per Capita
Percent of Non-Single Occupancy Vehicle Travel
Total Emissions Reduction

TAM Goals

The primary goal of TAM is to improve fiscal responsibility and responsiveness of State government and to ensure the efficient and cost-effective delivery of services. TAM practices help deliver the goals and objectives set by the agency, which are required by Georgia Code. Performance management is a tool utilized to support outcome-based investment decisions by tracking progress towards the agency’s goals through the use of performance measures. Performance management supplements and contributes to the optimization of asset management practices.

Strategic Approach

Asset Management Committee Structure

Asset management entails working across multiple offices within an organization and requires a variety of skill sets and knowledge. Having representatives from various functional areas that play a role in asset management is crucial to the TAM implementation process. Asset Management Committees were formed to enhance communication between the Subject Matter Experts (SMEs), Asset Managers and Executive leadership. The Committees are also directly responsible for the Department‐wide TAM implementation. Improved communication and clear roles and responsibilities will lead to better synergies and coordination of asset management practices and implementation. The Asset Management Committee responsibilities and structure are shown below.

Interstate Risk Assessment

State Route Prioritization

The Georgia Department of Transportation’s (GDOT’s) State Highway System consists of a diverse mixture of roadways including multi-lane Interstates, business spurs, US Highways, State Routes, city streets, and county roads. The State Highway System should ensure a well-connected network of high quality roads that comply with Georgia State Code and Federal law. GDOT undertook an assessment of the State’s 18,000 centerline miles, using Geospatial Information System (GIS) technology to graphically display and assist with the evaluation of proposed criteria, to establish the State Route Prioritization Network. Prioritization criteria were established in internal workshops, with additional input from members of GDOT management. Four categories of State Routes were established: Critical, High, Medium, and Low. GDOT implemented the results of this research to effectively allocate maintenance funding, and ensure a high level of service and quality on Critical and High Priority routes.

Transit Asset Management (TAM)

Transit Asset Management uses the condition of assets to guide the optimal prioritization of funding at transit properties in order to keep transit networks in a State of Good Repair (SGR). SGR is defined as the condition in which a capital asset is able to operate at a full level of performance. A capital asset is in a SGR when that asset is able to perform its designed function, does not pose a known unacceptable safety risk, and its lifecycle investments must have been met or recovered.

Transit Asset Management (TAM) Plan

In July 2012, the U.S. Congress enacted the MAP-21 (Moving Ahead for Progress in 21st Century) Act, which directed the Federal Transit Administration (FTA) to establish Transit Asset Management (TAM) requirements. In July 2016, FTA issued the Final Rule establishing requirements for Transit Asset Management (TAM), which apply to recipients and subrecipients of FTA funds. This was part of an overall Federal initiative to improve the state of good repair of transportation assets throughout the nation.

The FTA final rule has different requirements based on the relative size of the transit provider. Tier I providers are those operators with 101 or more vehicles in revenue service or operators of rail fixed-guideway public transportation systems. Tier II providers are Subrecipients of 5311 FTA funds, or are an American Indian Tribe, or are operators with 100 or fewer vehicles in general demand response service.

The TAM Plan requirements for smaller transit (referred to as Tier II) providers are less than those for the larger Tier I providers.

The Final Rule requires that TAM Plans for Tier II transit providers include the following four (4) elements:

Inventory of capital assets

A condition assessment of the capital assets for which the provider has capital responsibility

A description of decision-support tools used to estimate capital investment needs over time and develop the investment prioritization

A project-based prioritization of investments

Tier I providers are required to include the above listed four (4) elements plus additional elements such as TAM and SGR policy, implementation strategy, engagement activities, resources needed, and processes to ensure continuous improvements to TAM.

The Georgia Department of Transportation (GDOT) has developed this Group Transit Asset Management (TAM) Plan on behalf of 91 participant Tier I & II transit providers in accordance with Federal Transit Administration (FTA) requirements.
