“…The relationship between speed and ramp spacing of a weaving segment was investigated by Fitzpatrick et al using video record data from seven weaving segments in Texas ( 16 ). Multiple studies have also concluded that the entering ramp volume has a more pronounced effect on speed and capacity of a weaving segment than the total weaving volume, as the merging phenomena were found to be concentrated near the entry ramp ( 15 – 22 ).…”

This research proposes a new modeling framework for the analysis of freeway segments. The framework provides a continuum from the operation of ramp weave segments to an equivalent basic segment serving the same traffic with the same number of lanes and free-flow speed. This approach distinguishes between congestion effects caused by high v/c ratios from turbulence caused by merging, diverging, and weaving traffic, thus greatly simplifying the model form, and its extensibility to other freeway segment types. The paper presents an application of this new framework to the analysis of ramp weaves, which were not sufficiently sampled in the development of the HCM6 methodology. The proposed model is shown to be superior to the HCM6 method both in relation to explaining field observations of speeds and in its simplicity in application. The results include a new formula for capacity estimation that is highly sensitive to segment length, and a speed estimation model that converges for low weaving volumes or at very high weaving segment lengths to that observed at a basic segment. Because the proposed model is calibrated with data mostly from North Carolina, it is recommended that data at additional sites be included in a larger calibration effort to ensure its applicability to a broader set of weaving segment configurations.

“…The images have been stabilized and the trajectories have been extracted using a dedicated software (Knoppers et al., ). As in Marczak et al (), we consider in this article two 1‐hour samples, respectively, recorded on Thursday, September 15, 2011, and Friday, September 16, 2011. The traffic on the studied weaving section is local.…”

“…The authors exhibit that the acceleration–deceleration behavior and the decision to change lane of the weaving vehicles are influenced by the surrounding freeway vehicles. More recently, Marczak et al () analyzed detailed microscopic trajectory data collected on a weaving section in Grenoble (France). The authors prove that the lane‐changing behavior depends strongly on the prevailing traffic conditions.…”

The objective of this article is to propose an analytical traffic model adapted to freeway weaving sections. To this aim, a theoretical weaving section is considered at the macroscopic level as the superposition of two merges and two diverges. The model endogenously incorporates the capacity drop related to the weaving lane changes. It only depends on six parameters: three parameters of the fundamental diagram (the free‐flow speed, the jam density, and the wave speed in congestion), the vehicles’ acceleration, the relaxation factor, and the length of the anticipation zone. A sensitivity analysis proves that the acceleration rate and the relaxation parameter most influence the capacity drop. The analytical model agrees well with microsimulation results and empirical data collected on a weaving section in France.

“…Take as an example (Sun & Elefteriadou, ; Sun & Kondyli, ) where an instrumented vehicle‐based experiment was designed to analyze urban lane‐changing scenarios. Alternatively, Marczak, Daamen, and Buisson () conducted a descriptive empirical analysis of a trajectory data set from a freeway weaving section and constructed a lane‐changing database. These data have been used to validate several models attempting to reproduce the macroscopic lane‐changing effects on freeway capacity (Chen & Ahn, ; Marczak, Leclercq, & Buisson, ).…”

This article presents a new stochastic computational model for determining freeway capacity reduction as a result of lane-changing activity. The probability density function for the maximum flow that can be sustained on a freeway for a given lanechanging level is obtained. The results can be used to support freeway management strategies aiming to mitigate the negative consequences of lane-changing in freeway capacity. A pilot test using empirical data obtained from the B-23 freeway accessing the city of Barcelona proves the validity of the modeling approach.
