We use a cellular automata approach to numerically investigate traffic flow patterns on a single lane. The free-flow phase (F), the synchronized phase (S), and the jam phase (J) are observed and the transitions among them are studied as the vehicular density ρ is slowly varied. If ρ is...

In this paper, we study the phase transition from free flow to synchronized flow. We carry out the simulations under the speed limit condition with a car-following model, the “full velocity difference model.” We find that the transition is second-order if the speed limit region is long and...

Thermal hysteresis associated with ferroelectric to paraelectric phase transition is investigated in a ferroelectric copolymer of vinylidene fluoride and trifluoroethylene, using X-ray diffraction and incoherent neutron scattering. The lattice spacing derived from the diffractograms, shows...
