He call this "ASCII metro."
A set of 10 rules to controll each of metro cars 
(ii) Yet another example ... By Lisenkov Roman
Membership functions 5 for SPEED, 5 for DISTANCE and 5 for BREAK Membership function from one rule when speed = 20, distance = 80 and break = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ... By Meluch Michael
(ii) The other similar example of the rule "IF speed = slow AND distance = short THEN break = medium"
when speed = 10 and distance = 100 ... By Zhuk Igor
Membership function from a set of two rules when speed = 30, distance = 150 and break = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ... By Brutsky Vasily
Membership function from a set of ten rules Speed vs Break for a fixed value of Distance under a set of 10 rules 
similary
and
Thus
Draw surface by plotting points on 3D space of speed (x-axis) - distance (y-axis) - break (z-axis) under a set of 10 rules
