Intersection Control Evaluation (ICE) is a data-driven, performance-based framework and approach used to objectively screen alternatives and identify an optimal geometric and control solution for an intersection.
There are dozens of conventional and innovative intersection types and variations proven to work in the United States. With so many choices, it is important to use a consistent process to assess what options best meet project need and purpose. Utilizing ICE policies and procedures to evaluate and select the geometry and control for an intersection offers many potential benefits to road agencies and the traveling public, including:
A growing number of transportation agencies are developing and adopting ICE policies. Although there are differences among these ICE policies, they are consistent in emphasizing transparency, flexibility, and adaptability.
The ICE process is typically conducted in two stages:
The ICE process is one way to directly incorporate explicit safety performance metrics, using AASHTO Highway Safety Manual methodologies, in to the intersection project development process.
