1.1 A PROJECT APPLICABILITY CHECK ICE is REQUIRED when New signalization is proposed Major reconstruction of existing signalized intersection is proposed Adding exclusive left turns, adding intersection legs Conversion of a directional or bi directional median opening to a full median opening is proposed Driveway/Connection permit applications for Category E, F, G District Design Engineer (DDE) and District Traffic Operations Engineer (DTOE) consider an ICE a good fit for the project 15 Reference: FDOT Manual of Intersection Control Evaluation; Nov. 1, 2017; Section 2.3; Page 5
1.1 A PROJECT APPLICABILITY CHECK ICE NOT REQUIRED Work does not include substantive proposed changes to intersection Mill and resurface pavement; changing full median opening to directional median opening Minor intersection operational improvements Adding right turn lane or signal phasing changes or equipment upgrades Encouraged for local roadways, not required Recommended for ramp terminal intersections (stop control, signalized, or yield), not required 16 Reference: FDOT Manual of Intersection Control Evaluation; Nov. 1, 2017; Section 2.3; Page 5
