Interchange and Comact Grade Separated Junction: Classifications' System Considerations, Traffic Safety, and Operations Overview

The paper presents system considerations and classification criteria of interchange geometric design based on the new Israeli Interchange design guidelines (VOLUME III of geometric design standards for rural (interurban) highways and urban freeways).

The paper gives a methodological overview of interchanges systematical warrant in order to adjust and essentially construct an appropriate interchange that connects two intersecting highways. This warrant refers to the number of legs, partiality, functional classification, and access control type of intersecting highways zone (in the final stage of construction) based on highway classification. The paper also covers system considerations for implementing a compact grade separated junction (CGSJ) in a major highway, and traffic operation, safety, and public transport insights.
