Intersection Control Evaluation (ICE)

Traffic Operations Policy Directive 13-02: Intersection Control Evaluation (ICE)

Intersection Control Evaluation refers to the process and framework that a growing number of transportation agencies are adopting to provide a more balanced or holistic approach to the consideration and selection of access strategies and concepts during transportation planning, project identification and initiation processes that contemplate the addition, expansion or full control of major intersections (including interchange ramp termini).  “Full control” involves the use of signal, stop or yield control on each of the through and most major movements.

ICE Technical Assistance Program

The primary role and service of the ICE TAP is to provide technical assistance and training in support of TOPD implementation by Districts, local and regional transportation agencies, and other project sponsors.  Technical support is provided through consultation on matters related to:

  • The delegation of engineering authority to Districts for decisions to use the Single Point Interchange and roundabouts
  • Complex and controversial access proposals, strategies and concepts
  • The assessment, scoping, analysis and design of innovative access strategies – especially those for which formal technical guidance has not yet been established.
