Interchange Area Master Plans
Interchange Area Management Plans (IAMP) are effective planning tools to protect and extend the functional life of retrofitted and new interchanges. Developed originally in the State of Oregon, the IAMP s basically extend beyond the traditionally required Interchange Justification Reports (IJR) that focus on access to/from access controlled freeways or expressways. The TAMPs include the interchange crossroad facilities as well as the surrounding developable land within a minimum of 2,640 feet (805 meters). The plans evaluate the 20-year forecasted growth and determine the optimal: 1) interchange location and type (form), 2) ramp terminal control type, 3) crossroad access management plan, 4) local circulation and access to all parcels with 2,640 feet (805 meters); and 5) land use management plan strategies Since their inception, the TAMPs have proven instrumental in preserving the functionality and safety of interchanges and providing certainty to property owners in regards to near and long-term property access. This presentation will provide an overview of the IAMP elements and several case studies to demonstrate the breadth and benefits of these transportation plans.
