Algorithm 1

Algorithm for Dyna-MARL.
For each agent and episode do
IF is the critical section
  Initialise ,

  Initialise , ,
For each control step do                                                                                           (Loop I)
  (i) get detected data from each cell : , , , ,
  (ii) get state through (8) and (9)
  (iii) get action by -greedy policy (10)
  (iv) get , through (6) and do ,
  IF is the critical section
  update , through (2) and (12)
  ELSE update , , through (4) and (13)
  IF and end the algorithm
  ELSE get , , by (7) and do , , , and start loop II
   For each planning step do                              (Loop II)
   (i) generate flow rates for each cell : through (5)
   (ii) get the state
   (iii) get , and do ,
