Guidance and Tools for Intersection Control Evaluation
NCHRP Project 17-98 developed information and guidance on all aspects of intersection control evaluation (ICE) and incorporates enhanced safety screening methods, planning-level capacity methods for innovative intersections and interchanges, and a process for incorporating social equity. The information contained in this guide will help highway agencies and other organizations address relevant issues when considering the planning and implementation of intersections of highways and streets.

NCHRP Project 17-98 also developed and updated the following tools to facilitate the use of the guidance:

  • Capacity Analysis for Planning of Junctions (CAP-X) Tool
  • Planning and Preliminary Engineering Applications Guide Tool for Intersection Control Evaluation (PPEAG ICE Tool)
  • Equity Assessment Tool
  • Design Flags Calculator Tool
  • SSI Score Calculator Tool-Intersection
  • SSI Score Calculator Tool-Interchange
  • Safety Performance for Intersection Control Evaluation (SPICE)
  • Life-Cycle Cost Estimating Tool (LCCET)
  • Intersection Control Evaluation (ICE) Process Tool

DDSA Crash Tree Tool
The DDSA Crash Tree Tool allows users to generate crash tree diagrams based on the NHTSA Fatality Analysis Reporting System (FARS) or other crash datasets. Crash tree diagrams can be used as part of the systemic safety analysis process to help you identify and select the facility types where the focus crash types most frequently occur. The crash tree can have a number of different formats, depending on agency capabilities and data availability. The Systemic Safety Project Selection Tool includes additional information about the systemic safety analysis process, including examples of crash tree diagrams.
