The weaving length in roadway design is the distance between the channelizing islands or points where vehicles can change lanes or paths within a rotary or intersection. It is a critical factor in determining the efficiency and safety of traffic flow, as it provides sufficient space for vehicles to merge or diverge smoothly.

Weaving is an undesirable situation in which traffic veering right and traffic veering left must cross paths within a limited distance, to merge with traffic on the through lane. The German Autobahn system splits Autobahn-to-Autobahn.

Channelising islands are basically 2 roads or lanes which meet at one lane and after traveling some distance again split their ways.

What is weaving length of a road way?
