Dynamic Congested Traffic States of Density Difference Lattice Hydrodynamic Model with On-Ramp

Figure 1

Examples of congested traffic states measured on the German freeway A5 close to Frankfurt. (a) Pinned localized cluster (PLC), (b) Moving localized cluster (MLC), (c) Triggered stop-and-go waves (TSG), (d) Oscillating congested traffic (OCT), (e) Homogeneous synchronized flow (HST), and (f) Homogeneous congested traffic (HCT).
