Long Description: Figure 2: Graphic. Iowa Department of Transportation (Iowa DOT) systems planning process

This relational diagram illustrates the Iowa Department of Transportation (Iowa DOT) systems planning process.

The agency's strategic plan and Mission drives the long-range transportation plan (LRTP). Priorities and project in the LRTP inform the transportation asset management plan, including intelligent transportation system (ITS) device integration. System evaluation tools, including Infrastructure Condition Evaluation for Operations analysis, capability maturity model, and Infrastructure Voluntary Evaluation Systainability Tool sustainability, also inform the system/modal plan. Information from the LRTP flows into the system/modal plan, which includes transportation system management and operations (TSMO) strategic and program plans, which are also informed by the transportation asset management plan.

Information from the system/modal plan feeds into system reporting tools, including performance reports and accomplishment year plans. The system/modal plan priorities and projects flow into project evaluation tools (inluding TSMO service layer plan evaluation tools and project systems engineering analysis tools) and feasibility study/project definitions for TSMO service layer plans, which is also informed by the statewide and regional ITS architectures. Feasibility study/project definitions also inform the project evaluation Tools, which inform financial constraints and funding allocations. Financial constraints and funding allocations in turn inform commission management, which flows into the 5-year program under which ITS is integrated into highway projects.

Notably, service layer plans include those for the traffic management center, ITS and communications, traveler information, traffic incident management, emergency transportation center, work zone management, active transportation and demand management, and connected and autonomous vehicles.
