Intersection Control Evaluation
Program Overview
All modes of traffic cross paths as they travel through or turn from one route to another, and the points where different paths separate, cross, or join are known as conflict points. Intersections are designed points of conflict in all roadway systems. Limiting the number of conflict points at an intersection not only reduces the frequency and severity of crashes, but also improves the overall operation and mobility.
The Florida's Strategic Highway Safety Plan (SHSP) identifies intersection safety as one of the top emphasis areas for the state. In response to this call to action, and with direction from leadership, FDOT has developed an Intersection Control Evaluation (ICE) policy to aid in this effort. Implementing the ICE procedure on projects provides a transparent and consistent approach to evaluate intersection alternatives based on metrics such as safety, operations, cost, and social, environmental, and economic impacts.

- Scope of Services - Use this file to prepare the scope of services for an intersection control evaluation project. The scope file is the complete Standard Scope which includes services to be performed, submittal/deliverables, reporting, length of service, and fee estimate. All changes and/or additions to the Standard Scope shall be made in bold-italics to help draw attention to the users of project specific changes.
- Staff Hour Estimation - This document (including ICE guidelines, ICE analysis and ICE plans) provides detailed information on intersection control evaluation, breaking down the activities and tasks that can appear in a scope document, along with recommended staff hour ranges to provide a detailed effort of the intersection control evaluation.
