Hi SUMO,
I have found a bug based on the SUMO Guide on how to generate Trips randomly as
well as controlling its arrival
rate<http://sumo.dlr.de/wiki/Tools/Trip#Arrival_rate>.
Using randomTrips.py, the script will literally never stop generating a trip
when I put the option --period 0 or -p 0.
I have known of this issue after waiting for the script to complete after an
unreasonable amount of time (An hour, while a relatively large number of
approximate 608,400 vehicles takes less than 10 minutes) and I saw the script
has generated a > 10GB of SUMO Trip File.
What I wanted to do:
* To specify SUMO Trips for departing 10 vehicles for every step from Start
(-b) til End (-e)
What did I tried:
1: -p 1 --binomial x
Where variable x = Ceiling on the 1% of entire duration between Start Time and
End Time
Python code only of relevance:
x = int(math.ceil(0.01 * (endTime - startTime)))
exec += str.format(" -p 1 --binomial {0}", x)
2: -p y
Where variable y is 1 / (Number of vehicles to depart at every step)
Python code only of relevance:
y = raw_input("Please specify the number of vehicles to depart in each step: ")
period = 1 / (y)
toBeExec += str.format(" -p {0}", period)
Both did not do what I expected.
The first method has a non-fixed number of vehicles to depart at every step.
The second method departs vehicles in different sub-step (Departure time is a
Float value, not integer)
Regards,
Samuel Lee
