Intersection Control Evaluation (ICE):

The Pennsylvania Department of Transportation (PennDOT) has developed an Intersection Control Evaluation (ICE) policy to consistently consider and screen from among many proven combinations of geometry and traffic control when a new intersection or existing intersection modification is first contemplated. The goal of ICE is to better inform the decision-making of the road agency to identify and select an alternative that meets the project purpose and reflects the overall best value, in terms of specific performance-based criteria within available resources. As with most transportation studies, ICE is scalable, meaning the corresponding level of effort for screening and analysis should be commensurate with the magnitude and nature of the project – less effort for simple, more effort for complex. The premise of an ICE is the same whether it involves new intersections or modification to existing intersections. The users should use their judgment to apply the ICE framework in the way that meets project needs and the objectives of the ICE Policy. Ultimately, this ICE policy is intended to foster thoughtful consideration of alternative intersection types and ensure a holistic, quantitative analysis is completed when selecting an intersection control type for intersections across the Commonwealth.
