    Scaling from Circuit Experiment to Real Traffic Based on Optimal Velocity Model

    The optimal (OV) model was proposed to explain the physical mechanism of jam formation. The emergence of a traffic jam can be understood as a kind of dynamical phase transition. We confirmed the ph...

    Critical Density of Experimental Traffic Jam

    In a previous experiment, we have demonstrated that a traffic jam emerges without any bottleneck at a certain high density. In the present work, we performed an indoor circuit experiment in Nagoya Dome and est...

    Detailed Data of Traffic Jam Experiment

    We show detailed data of two traffic jam experiments on a circuit. In the experiments, a traffic jam emerges spontaneously without any bottlenecks. We found the power law nature in time series of average velo...

    Molecular mechanism of antidiabetic zinc–allixin complexes: regulations of glucose utilization and lipid metabolism

    We previously reported new zinc complexes of allixin [bis(allixinato)zinc] and its derivative bis(thioallixin-N-methyl)zinc that demonstrated excellent antidiabetic activity in type 2 diabetic mellitus KKAy mice....

    Action mechanism of bis(allixinato)oxovanadium(IV) as a novel potent insulin-mimetic complex: regulation of GLUT4 translocation and FoxO1 transcription factor

    Bis(allixinato)oxovanadium(IV), VO(alx)2 (alx is 3-hydroxy-5-methoxy-6-methyl-2-pentyl-4-pyrone), has been reported to act as an antidiabetic agent in streptozotocin-induced type-1-like and obesity-linked KKAy ty...

    Phase Diagram of Group Formation in 2-D Optimal Velocity Model

    We present a mathematical model for self-driven particles (2-D Optimal Velocity Model), which can reproduce a big variety of patterns in group formation and phase transition physics, by changing only two contr...

    Scale-Free Features in the Observed Traffic Flow

    Scale-free features in traffic flow are discussed based on observed data. The observed traffic flow is known to contain some periodic motions reflecting our social activities. By employing the DFA (Detrended F...

    Delay of vehicle motion in traffic dynamics

    We demonstrate that in the Optimal Velocity Model (OVM) delay times of vehicles coming from the dynamical equation of motion of OVM explain the order of delay times observed in actual traffic flowswithout introdu...
