Re: [sumo-user] Number of vehicles in each timestep changes

the low number if vehicles at the start is typical because the networks starts empty and has to fill up.
The high number of vehicles later in the simulation occurs because that scenario is horribly congested. Mostly due issues with the network ( I'm planning to release an updated version of the scenario this year.
Until then you could down-scale the traffic demand to avoid the worst congestion (--scale 0.5 or lower)

I'm new to SUMO, and I'm trying to export some traces, so I can use them in python. I exported some FCD Output (xml) files from a simulation, each with a 10 minute length, at different starting times. I'm using the traces from this project. They all go from around 20 vehicles in the starting seconds to around 10000 to 20000 in the last seconds. I exported these files using the --fcd-output option, and giving a begin and end times. Why do the number of vehicles change so much? Is there a way I can fix this?

Below is a plot of the number of vehicles in each timestep in one of the files.
