Abstract

The objective of this project is to revise the Oregon Department of Transportation (ODOT) Intersection Control Evaluation (ICE) Tool to create a more transparent and comprehensive framework for comparing intersection alternatives during early project development. The original ICE tool relied heavily on qualitative scoring and generalized planning-level cost assumptions, limiting its ability to consistently evaluate tradeoffs between safety, operations, multimodal performance, environmental impacts, right-of-way constraints, maintenance needs, and project implementation costs. The revised framework restructures the evaluation process into a planning-level, benefit-cost-oriented methodology that separates impact and cost components across all major evaluation categories.

The revised tool introduces expanded and standardized evaluation frameworks for safety, environmental and regulatory permitting, right-of-way, efficiency, freight, active transportation, maintenance and operations, stakeholder posture, and project risk. Across these categories, the methodology incorporates planning-level impact estimation, category-specific cost estimation, weighted scoring systems, and comparative evaluation methods intended to improve transparency, consistency, and analytical defensibility during conceptual alternative screening. The revised tool also includes updated spreadsheet architecture, automated workflows, VBA-based automation features, and both simplified and detailed user input modes.

Overall, the revised ICE framework provides a more flexible and comprehensive approach for evaluating intersection alternatives and supports transportation decision-making based on long-term lifecycle performance rather than short-term construction cost alone.
