Traffic states and jamming transitions induced by a bus in two-lane traffic flow

Nagai, Ryoichi; Nagatani, Takashi; Taniguchi, Naoki - In: Physica A: Statistical Mechanics and its Applications 350 (2005) 2, pp. 548-562

We study the traffic states and jamming transitions induced by a bus (slow car) in a two-lane traffic of cars. We use the dynamic model which is an extended one of the optimal velocity model to take into account the lane changing. The fundamental (flow-density) diagram is presented. The...

Phase separation and evolution of one pulse jam in traffic flow

Nagai, Ryoichi; Onouchi, Tunetoshi; Nagatani, Takashi - In: Physica A: Statistical Mechanics and its Applications 354 (2005) C, pp. 571-581

formation of plateaus is due to the phase separation in the dynamical jamming transition. It is found that the transition line … between two waves forming plateaus is consistent with the coexisting line in the jamming transition. …

A nonlinear diffusion model for granular segregation

Fernandes, H.C. Marques; Arenzon, J.J; Levin, Y; Sellitto, M - In: Physica A: Statistical Mechanics and its Applications 327 (2003) 1, pp. 94-98

We study a set of nonlinear diffusion equations describing the evolution of densely packed particles under gravity subject to random vibrations. Although the thermodynamics of the model predicts no phase separation at all, the dynamics displays both normal and reverse segregation depending on...

Optimal admission time for shifting the audience

Itoh, Taira; Nagatani, Takashi - In: Physica A: Statistical Mechanics and its Applications 313 (2002) 3, pp. 695-708

admission time for shifting the audience is related with the jamming transition of pedestrian flow. When the audience goes away …
