We study the unidirectional flow of a binary mixture of biased-random walkers on a square lattice under a periodic boundary. The lattice-gas mixture consists of two types of slender particles (walkers) which have different biases (drift coefficients). When the density is higher than a critical...

A two-dimensional square lattice system, on which flexible, chainlike, self-driven objects move randomly but are drifted to a same direction, causing a unidirectional net flow, is investigated by numerical simulations. It is shown that the objects exhibit a freezing transition from a smoothly...

Counterflow of students going on all fours is investigated by experiment and simulation. The experiment is performed for the channel with open boundaries. Two types of students going to the right and to the left are taken into account. The video recordings and measurements of individual arrival...

We study the behavior of walkers sidling through the crowd in the counter flow of pedestrian. When a walker enters the crowd, he turns himself sidelong to avoid a collision and edge through the crowd. The biased random walk model is extended to take into account the sidle effect. We present...

Evacuation processes of walkers (pedestrians) and crawlers are investigated by experiment and simulation. The experiments are performed for walkers and crawlers evacuating from the corridor (channel) with an exit. All students go on all fours in the evacuation experiment of crawlers. The video...

The traffic flow model with optimal velocity is extended to take into account the velocity-dependent sensitivity. The dependence of the jamming transition upon the sensitivity is investigated in the extended optimal velocity model. The phase transition among the freely moving phase, the...

Jamming transitions of pedestrian traffic are investigated under the periodic boundary condition on the square lattice by the use of the lattice gas model of biased random walkers without the back step. The two cases are presented: the one with two types of walkers and the other with four types...

The lattice models of traffic are proposed to describe the jamming transition in traffic flow on a highway in terms of thermodynamic terminology of phase transitions and critical phenomena. They are the lattice versions of the hydrodynamic model of traffic. Two lattice models are presented: one...

The car-following model of traffic is extended to mimic bus behavior in the bus route. We study the phase transitions and bunching in the bus route model by both simulation and linear stability analysis. It is found that the jamming transitions among an inhomogeneous bunching phase, the...

We study the traffic congestion and dispersion of vehicles occurring on a single lane highway in Hurricane evacuation. The traffic congestion depends on both sensitivity and speed of the leading vehicle. When the leading vehicle moves with low speed, the vehicular traffic exhibits the stop and...
