In the traci_tutorial runner, the threshold of pEW controls the probability
for a vehicle to be generated in each second.
If you copy the code, you can set a lower threshold to maintain the same
amount of traffic.
Also, consider using flow definitions with probability attribute to achieve
the same effect without a python script (

).
