HOW TO USE IT

This section could explain how to use the model, including a description of each of the items in the interface tab.

THINGS TO NOTICE

This section could give some ideas of things for the user to notice while running the model.

THINGS TO TRY

This section could give some ideas of things for the user to try to do (move sliders, switches, etc.) with the model.

EXTENDING THE MODEL

This section could give some ideas of things to add or change in the procedures tab to make the model more complicated, detailed, accurate, etc.

NETLOGO FEATURES

This section could point out any especially interesting or unusual features of NetLogo that the model makes use of, particularly in the Procedures tab. It might also point out places where workarounds were needed because of missing features.

RELATED MODELS

;; V. 0.1

;; There are two cars species: northbounds and eastbounds.

 
globals[ phase ]

breed[northbounds northbound]
breed [eastbounds eastboud]

;; These two species populate a two dimmensional square lattice, with boundary conditions.
;; Each lattice site can have three states i) empty ii) has a northbound car iii) has an east bound car.
