Dynamical transitions in peak elevator traffic

Nagatani, Takashi - In: Physica A: Statistical Mechanics and its Applications 333 (2004) C, pp. 441-452

nonlinear map model to the dynamics of M elevators. We investigate the effect of elevator's number M on the dynamical transition …

Dynamical transition in random supply chain

Nagatani, Takashi - In: Physica A: Statistical Mechanics and its Applications 335 (2004) 3, pp. 661-670

We present the stochastic model of the supply chain composed of u series machines and buffers. Each machine has an adaptation time (delay) different from the other and each buffer has a capacity of storage different from the other. We extend the deterministic supply chain model to the stochastic...

Complex motions of shuttle buses by speed control

Nagatani, Takashi - In: Physica A: Statistical Mechanics and its Applications 322 (2003) C, pp. 685-697

We study the dynamical behavior of shuttle buses on a route where N buses shuttle between an origin and a destination repeatedly. We present the dynamic model of shuttle buses to take into account the speed control depending on time headway between buses. The model is described by N-dimensional...

Transitions to chaos of a shuttle bus induced by continuous speedup

Nagatani, Takashi - In: Physica A: Statistical Mechanics and its Applications 321 (2003) 3, pp. 641-652

We study the effect of continuous speedup on the dynamical behavior of a single shuttle bus. We present a nonlinear map model of a shuttle bus to take into account the continuous speedup. When the shuttle bus is delayed, the bus speeds up continuously to overcome the delay. If the shuttle bus...

Dynamical behavior of N shuttle buses not passing each other: chaotic and periodic motions

Nagatani, Takashi - In: Physica A: Statistical Mechanics and its Applications 327 (2003) 3, pp. 570-582

We study the dynamical behavior of shuttle buses on a route where N buses (N⩾2) shuttle between a starting point and a destination without passing. We present the dynamical model of N shuttle buses to take into account the interactions between buses and passengers. The model is described in...

Dynamical transitions to chaotic and periodic motions of two shuttle buses

Nagatani, Takashi - In: Physica A: Statistical Mechanics and its Applications 319 (2003) C, pp. 568-578

We study the dynamical behavior of two shuttle buses on a route where two buses shuttle between a starting point and a destination. We present the dynamical model for the two shuttle buses. When a bus catches another, the bus restarts after delay time Tmin. The distinct dynamical states (the...

Transition and saturation of traffic flow controlled by traffic lights

Sasaki, Masashi; Nagatani, Takashi - In: Physica A: Statistical Mechanics and its Applications 325 (2003) 3, pp. 531-546

Dynamical transition to periodic motions of a recurrent bus induced by nonstops

Nagatani, Takashi - In: Physica A: Statistical Mechanics and its Applications 312 (2002) 1, pp. 251-259

We study the dynamical behavior of a recurrent bus on a circular route with many bus stops when the recurrent bus passes some bus stops without stopping. The recurrent time (one period) is described in terms of a nonlinear map. It is shown that the recurrent bus exhibits the complex periodic...

Dynamical transition in a coupled-map lattice model of a recurrent bus

Nagatani, Takashi; Yoshimura, Jin - In: Physica A: Statistical Mechanics and its Applications 316 (2002) 1, pp. 625-636

We investigate the dynamical behavior of a recurrent bus on a cyclic route with many bus stops. The maximum capacity of the bus is taken into account to study the dynamics of a waiting queue at a bus stop. We build a coupled-map lattice model of a cyclic bus. The recurrence time (one period) on...
