Definition of TAM Source: All sources in this presentation are AASHTO’s Transportation Asset Management Guide (Jan. 2011) and NCHRP 632 (2009), unless specific to CDOT or otherwise noted.
Transportation Asset Management (TAM) is a strategic and systematic process of operating, maintaining, upgrading and expanding physical assets effectively throughout their life cycle. It focuses on business and engineering practices for resource allocation and utilization, with the objective of better decision making based upon quality information and well defined objectives. 4

Begin with the End in Mind • Goals and Ends of TAM Shown Above – Goals of TAM • Minimize life‐cycle costs for managing and maintaining transportation assets • Support a strategic approach for resource allocation that uses a performance‐based approach to maintain and preserve assets
– The 5 Core Questions TAM Answers
10
Begin with the Beginning in Mind DATA! • Data is the foundation of TAM • All other components of TAM rely on transportation asset data • All results and credible analysis are based on reliable data about the transportation assets that are under management 11
Data Value Chain Data Analyzed to produce Info needs drive data requirements
Information Communicated and used in making Decisions drive info requirements
Decisions Implemented to achieve Goals and Objectives drive decisions

Data about Physical Assets • Kinds of Data – Location (GIS) – Physical Characteristics • Height, Length, Width, Depth • Model ID, Composition
– Age & Other Events – Condition
• Specifics vary by asset type • This data is also an asset – Not a physical asset 14

Field Data Collection • Would take ~ 5 times more in time and money – Truck use – Fuel – Weather delays – Physical effort – Safety effort
• No one had to work on the roadway

Manage Edits • After you Tap the Manage Edits Tab A Screen Opens telling you how many New Features have been Collected • Tap the View Updates Tab and a List of Updates Appears
• Tap on a Feature and The Type is displayed
25
Manage Edits • Tap on the Feature again and your Editing Choices Open • It is a little hard to know which Individual Feature was selected so Tap on Browse on Map to View the Feature on the Map
• The Selected feature Is Highlighted • If that is Feature you wish to edit Tap Done to go to the Updates Page
26
Field Data Collection • Cannot avoid boots on the ground! • Some assets can’t be seen from roadway photos – Culverts – partial or complete – Underground utilities – Irrigated landscape

GIS Advantages •
•
•
•
Foundation – Single geographic reference for all source material and data – Multiple views of same data – Enables CAD integration – Data collection tools now integrate with GIS Quality is enhanced using GIS – Standard schemas, domains, and ranges – Drop down lists – Range checks – Visual feedback during field collection – Topology – Integrate versions Workflow management – Check out to ArcGIS Mobile – Data from ArcGIS Mobile (ETL) – Check in to Esri Geodatabase – Distributed data acquisition and editing – Apply linear referencing ETL – Functional Locations – Geographic overlay – Insert / integrate within SAP – Pontis – Deighton
