We study completely asymmetric two-channel exclusion processes in one dimension. It describes a two-way traffic flow with cars moving in opposite directions. The interchannel interaction makes cars slow down in the vicinity of approaching cars in the other lane. Particularly, we consider in detail the system with a finite density of cars on one lane and a single car on the other. When the interchannel interaction reaches a critical value, a traffic jam occurs, which turns out to be of first…

Spontaneous symmetry breaking in a two-lane model for bidirectional overtaking traffic
Firstly, we consider a unidirectional flux of vehicles, each of which is characterized by its 'natural' velocity v drawn from a distribution P(v). The traffic flow is modeled as a collection of
Studying on the Bidirection Two-lane Mixed Cars Traffic Flow Model
A new bidirectional two-lane mixed cars traffic flow model is proposed, which considers canceling the restrictions on the queue of low-speed car, combine with FI model, and thinks when the car is changing lane, the behind vehicles from its adjacent lane have effects on it.
Exactly solvable statistical model for two-way traffic
We generalize a recently introduced traffic model, where the statistical weights are associated with whole trajectories, to the case of two-way flow. An interaction between the two lanes is included

A system composed of two parallel totally asymmetric simple exclusion processes with open boundaries, where the particles move in the two lanes in opposite directions and are allowed to jump to the other lane with rates inversely proportional to the length of the system, undergoes a discontinuous phase transition.

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

This paper shows connections between fluid-dynamical traffic flow models, which derive from the Navier-Stokes-equation, and particle hopping models, and starts building a foundation of a comprehensive dynamic traffic theory, where strengths and weaknesses of different models can be compared, and thus allowing to systematically choose the appropriate model for a given question.
