An Exactly Solvable Two-Way Traffic Model With Ordered Sequential Update
Within the formalism of matrix product ansatz, we study a two-species
asymmetric exclusion process with backward and forward site-ordered sequential
update. This model, which was originally introduced with the random sequential
update, describes a two-way traffic flow with a dynamic impurity and shows a
phase transition between the free flow and traffic jam. We investigate the
characteristics of this jamming and examine similarities and differences
between our results and those with random sequential update.Comment: 25 pages, Revtex, 7 ps file
Dilemma game in a cellular automaton model with a non-signalized intersection
We numerically study traffic flow, energy dissipation and social payoff in the
Nagel-Schreckenberg model with a non-signalized intersection. In terms of game theory, we
analyze dilemma game observed in some traffic states. There are four traffic phases:
free-flow phase, phase-segregated 1, phase-segregated 2 and jammed phase in the case of
vmax > 1. In phase-segregated 1, maximum traffic flow
corresponds to minimal energy dissipation. Dilemma game is observed at the
phase-segregated 1 in the case of vmax > 1, and phase
segregation state when vmax = 1. Theoretical analyses give an
agreement with numerical results
