Explanation of Complex Dynamics of Congested Traffic in NGSIM Data with Three-Phase Traffic Theory

An explanation of congested traffic in NGSIM-data in the context of the three-phase traffic theory is presented. Complex spatiotemporal dynamics of moving jams observed in NGSIM-data is explained in three-phase traffic theory by the nucleation-interruption effect occurring in metastable synchronized flow. The nucleation-interruption effect in metastable synchronized flow is associated with the dual role of lane changing in the synchronized flow as well as with the vehicle merging from on-ramps onto the main road and from the main road to off-ramps. The dual role of lane changing is as follows: lane changing can lead either to the occurrence of a growing moving jam or to the jam dissolution in metastable synchronized flow.
