Geometric design of transportation facilities must provide for the resolution of traffic conflicts. In general, these may be classified as
Merging conflicts - Conflicts occur when vehicles enter a traffic stream
Diverging conflicts - Conflicts occur when vehicles leave the traffic stream
Weaving conflicts - Conflicts occur when vehicles cross paths by first merging and then diverging
Crossing conflicts Conflicts occur when they cross paths directly
There are three basic ways of resolving crossing conflicts.
Time sharing solutions - involve assignment of the right-of-way to particular movements for particular times
Space-sharing solutions - convert crossing conflicts into weaving conflicts
Grade-separation solutions - eliminate the crossing conflict by placing the conflicting traffic at different elevations at their point of intersection
Freeway interchanges are classified primarily according to the way in which they handle left- turning traffic.
Diamond interchanges - employ diamond ramps, which connect to the cross road by means of an at- grade intersection.
Cloverleaf intersections - employ loop ramps, in which vehicles turn left by turning 270° to the right.
Direct interchanges - employ direct ramps, in which vehicles turn left by means of a left-turning ramp that is grade-separated as it crosses both traffic streams.
It is used to provide access to adjacent property.
