Abstract

Traffic operations on weaving sections are characterized by intense lane changing manoeuvres and complex vehicle interactions, which can lead to certain variations in travel time. One of the factors affecting the travel time variability of weaving sections is the length of the weaving section. In this paper, the relation between weaving section length and travel time variability is investigated. This done based on both a simulation approach and on empirical data. Both indicate a relation that there exists a certain weaving section length threshold under which the travel time variability strongly increases. These implications of this (preliminary) result are discussed for geometric design purposes and for possible control applications which can reduce the travel time variability in the short weaving sections.
