ICE PURPOSE

  • Consistently consider multiple context‐sensitive control strategies when

planning a new or modified intersection through…

  • Informed decision‐making considering
  • purpose and need, context classification, safe travel facilities for all road users, with the
  • verall best value
  • Select a context‐sensitive control strategy considering
  • the goals and needs of the community and all road users
  • Measure the control strategy’s value using
  • performance‐based criteria
  • Promotes thoughtful consideration of alternative intersection types

through quantitative analysis

INTERSECTION TYPES

 Displaced Left Turn  Left turns and

through movements

  • perate concurrently

 Also called

continuous flow intersection

 Could have displaced

lefts on 2 legs instead

  • f all 4

FDOT ICE IMPLEMENTATION PLAN

  • 2018: Training and Acclimation
  • Implementation Focus: District Training
  • Two intersections per district
  • 2019: Districts Identify & Conduct ICE Analysis for Additional

Locations

  • Implementation Focus: Refine ICE Process
  • Evaluate minimum of three projects in these offices/focus areas
  • PD&E
  • Traffic Operations
  • Access Management/Permitting
  • 2020: Full ICE Procedure Implementation by Districts
  • Implementation Focus: Mainstream ICE Process
  • ICE Manual Procedures fully effective January 1, 2020
  • 3 Step Roundabout Analysis replaced by ICE
  • Quality Assistance Reviews (QAR) starting in Year 4
