The Simon-Gutowitz bidirectional traffic model (Phys. Rev. E 57, 2441 (1998)) is revisited in this letter. We found that passing cars get stuck with oncoming cars before returning to their home lanes. This provokes the occurrence of wide jams on both lanes. We have rectified the rules for lane changing. Then, the wide jams disappear and the revisited model can describe well the realistic bidire...

As more drivers use the roadways in the U.S. and abroad, traffic problems only become more important to understand and, hopefully, resolve. Among the long list of traffic problems, traffic jams are quite near the top. The ”shockwave traffic” theory has emerged recently as a promising way to model the propagation of these traffic jams by describing them as waves.[1] In this theory, the shockwave...

There is an increasing demand for using vehicles by growing the population in modern smart cities. This rise has led to traffic jams most of the time, especially during rush hours. In order to tackle this problem different solutions have been proposed in the literature, where each one focuses on a special facet of this problem. In this paper a type-2 fuzzy predictor has introduced so that it es...

We study several deterministic one-dimensional traffic models. For integer positions and velocities we find the typical high and low density phases separated by a simple transition. If positions and velocities are continuous variables the model shows self-organized criticality driven by the slowest car.

Fresh fruit of three strawberry cultivars Fragaria ananassa × Duch. (cvs. ‘Clery’, ‘Honeoye’ and ‘NF 421’ (Asia)) were investigated and used to produce jams, which were analyzed before and aft er dark storage at 20 °C for six months. Th e aim of this investigation was to characterize all the samples in relation to the total phenolics, fl avonoids, nonfl avonoids, total anthocyanins and antioxid...

Phantom jams,” traffic blockages that arise without apparent cause, have long frustrated transportation scientists. Herein, we draw a novel homology between phantom jams and a related class of self-sustained transonic waves, namely detonations. Through this analogy, we describe the jam structure; favorable agreement with reported measurements from congested highways is observed. Complementary n...

A full velocity difference model for traffic flow, including driver’s reaction time delay is considered. The uniform flow and traffic jams are interpreted through stability and bifurcation analysis. Specifically, the uniform flow is represented by the equilibrium of the model. Linear stability reveals that when the equilibrium loses its stability, local bifurcation turn up through Hopf bifurcat...
