relationship between network-level priorities and the projects entering the development pipeline.
Understand the trade-offs when choosing projects to develop.
Give the governance process a clear communication tool to help align priorities.
Make data-driven decisions
TAM Principles Asset management is policy driven. Funding decisions reflect
Iowa DOT’s vision for how the transportation system should look in the future.
Asset management is performance based. Iowa DOT understands the condition of its assets, defines performance targets, and makes decisions that support these targets.
Asset management involves making trade-offs. Iowa DOT has options for how to allocate transportation funding. It evaluates these options and makes informed decisions regarding the best path forward.
Asset management relies on quality information. Iowa DOT uses data and analytical tools to support its decisions.
Asset management requires transparency and accountability. Iowa DOT documents how funding decisions are made. It monitors performance, tracks progress towards performance targets, and reports on results.

Automated processing of a priority algorithm on all projects currently planned or programmed
Calculates performance scores based on many other DOT-managed business data (bridges, pavement, traffic, etc)
Allows robust filtering and analysis of both project- level and performance- level metrics
Bringing It All Together

23
Builds upon the Prioritization app framework to allow new projects to be proposed
Input fields vary based on the program funding or work groups that are specified
Bringing It All Together
25
Project extent is based on DOT LRS routes, ensuring every element of the project is a valid road segment
Users can edit the start and end of each route so that only what is being proposed for improvement is included
A link to Transcend’s RoadAnalyzer® and PathWeb are provided for additional route review
Bringing It All Together

Associated geometries provide the basis for live impact analysis of many other GIS layers
Each layer’s impact total is listed in parentheses
Layers can be turned on in the map and each impacted feature can be viewed for more information
Bringing It All Together
30
When a project is selected, the user can filter and asses all contributors to the priority score
Users are also able to see the level of complexity of a project, and how that compares to other, similar projects
A live assessment of project schedule is shown, allowing users to discover specific events that are contributing to delay
The user submitting a project scope may continue to refine all project details until satisfied with impacts and priority scoring
Bringing It All Together
32
Using INRIX data and other DOT sources, a live assessment of congestion is displayed
Additional information relating to the contributors to the project estimate can be viewed
Cost & budget information is pulled directly from DOS business data
Bringing It All Together
But first, self reflection…
Successes Developed and integrated many data flows Beginning to make data driven decisions Becoming integrated into our business processes Building trust with our Transportation Commission Increase coordination between program managers and Districts Challenges Data Gaps Maintenance overhead Good vs best…explicit tradeoffs…hard part to say no to a good project Risks Becoming too tied to any one tool Becoming complacent in our data collection Keeping a tool from becoming a gate instead of a tool
What’s Next?
Big Next Steps… Utilize for part 667 evaluations….align with alternative selection Include analysis for Programmatic CE’s Expand Data Integration….additional assets Including Valuation & Benefits Snapshots (Concept/Design/Post Construction) Continuous Evolution of Criteria and Scoring…mobility, freight, and road classification Utilize for mitigation projection needs based on scoped projects
