Hi all,

I noticed that the throughput flow of intersections can be accessed in the 
output file of loop detectors. But I am wondering can we use traci to get the 
real-time throughput between time [t-interval, t]?


# Loop[j] is the lsit for loop detector j
Loop = [[] for x in range(Num_detectors)]
Count = [[] for x in range(Num_detectors)]


Loop[j].append(traci.inductionloop.getLastStepVehicleIDs(str(j)))
if Loop[j][step] != Loop[j][step-1]:
Count[j].append(1)
else:
Count[j].append(0)


To get how many vehicles passed the intersection, I retrived the ID list on a 
loop detector and try to check whether it changed last time. Is it the correct 
way? 


Thank you,
Hao
