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...

We study the counter flow of slender particles on square lattice under periodic boundaries. Two types of particles going to the right and to the left are taken into account, where the size of right particles is larger than that of left particles. The counter flow of slender particles with...

We study the dynamical behavior of a few shuttle buses that pass each other freely on a cyclic route. We present a discrete dynamical model of the shuttle buses to take into account the interactions among buses and passengers. It is found that the bus exhibits a chaotic motion by the free...

We study the dynamic behavior of an elevator induced by a periodic inflow of passengers. An elevator schedule is closely related to the dynamics. We present the modified circle map model for the dynamics of the elevator traffic. The motion of the elevator depends on both loading parameter and...

The traffic states are investigated for the noisy traffic flow in the presence of a bottleneck under the open boundary condition. The phase diagrams of the different kinds of congested traffic are presented for different values of sensitivity (the inverse of delay time). It is shown that the...

We study the traffic flow controlled by traffic lights on a single-lane roadway by using the optimal velocity model. The characteristic of traffic flow is clarified for the three different strategies of traffic light control: the simple synchronized, green wave, and random switching strategies....

The jamming transition from the free traffic to the oscillatory traffic is investigated with the unidirectionally coupled map lattice model which has the hyperbolic tangent local map. Spatio-temporal structures in the jamming transition are found with the use of numerical simulation. The traffic...

Pattern formation is investigated in the pedestrian counter flow within a channel where there are two types of walkers going to the right and to the left. The lattice gas model of biased random walkers is extended to take into account following the front persons with the same direction (model...

We study the dynamical behavior of a few shuttle buses when they pass each other freely and control the speed to retrieve the loading's delay. The dynamics of the buses is expressed in terms of the nonlinear maps. The tour times of buses and the time headway between buses exhibit the complex...

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...
