Cellular automata model on AIS-based for variable two-way waterway
Abstract: We aim at “heavy
traffic direction” and “light traffic direction” in two-way waterway traffic
and attempt to promote the transit capacity of two-way waterway system.
Design/methodology/approach: We propose overtaking rules, head-on rules
and a cellular automaton model for variable two-way waterway on AIS-based on
the basis of NaSch (Nagel-Schreckenberg) model.
Findings: By numerical simulation to the two situations which allow
changing lane and prohibit changing lane, we obtain fundamental functions
between traffic flux (speed) and density and find that changing lane can
promote traffic flux and average speed of two-way waterway system under the premise
of no impact to the traffic order, and when waterway ship traffic is dense,
flux of waterway system has a visible promotion, and when traffic is sparse,
average speed of waterway system adds significantly.
Originality/value: The paper presents a method to analyze and promote
transit capacity of two-way waterway.
Keywords: cellular automata,
