Dear Community,
I had been exploring the use of slowDown() while using traci API to control
the simulation. The description of the method says -
"Changes the speed smoothly to the given value over the given amount
of time in seconds (can also be used to increase speed)."
While using the method,
Hello all,
We're found an interesting phenomenon during processing SUMO trajectory
(from the fcd output file) as below:

As you can see, some times the vehicle stopped but the speed was not 0, and
sometimes the vehicle moved when the speed was 0.
Do you know the reason of this
Possibly your simulation is running afoul of

already).

If you need detectors with non-zero length you can use laneAreaDetector or

Hello Jakob,
Thank you for your example, I tried to imitate it and it worked.
Actually, my intuition was right, but I struggled in understanding the
network properties. For instance, a connection from an edge to the same
edge is not trivial, look at the below example. Just notice the bold edges
Hello Harald,
Thanks for your suggestions
a) I agree that using the same attribute name for two related but subtly
different things is adding unnecessary confusion (I fact, confusion was
recently observed).
Since the 'period' attribute of flows has a lot of history behind it I'll
keep this
Hello all,
I'm processing induction loop data via TraCI, including entry time and leave
time of each vehicle passing the induction loop detector, as well as the
detector occupancy for each simulation step.
With respect to this, I have a few questions:

OK! Thanks for your reply.

Hello Herald,
Thanks for coming up with a proposal.
In my opinion, the word route is ambiguous since it is used for defining a
path as well as a public transit line (or route). Hence, a new class named
line or ptLine should be formed. This class will contain all the properties
of a public transit
Currently, the only method to determine departure times is to call
traci.simulation.getDepartedIDList in every simulation step and check
whether the vehicle of interest is part of that list.

Netconvert can read and write matsim networks.

Interesting. Thank you Jakob and Ilya for your comments. |@Ilya|: I
don’t use public transport, but I do use parking areas. Will let you

I am trying to use od2trips and duarouter to generate train paths. The issue is
that od2trips doesn't want to recognize the rail type.

Hello,
for density, you need to use the total lane-length of the network rather
than the edge length (edges with more lanes have more space).
Other than that, your formulas are okay.

I'm currently running Sumo 1.6 and the TraCI Version is 20.

By default, vehicles all start on the right side of the road and his limits

If you define departLane="free" you will get higher insertion flow. See

After calling a traci.vehicle function that modifies type-specific

vehicle is copied, modified and re-assigned to the vehicle. This is to
ensure that all other vehicles with the same type are not affected.
Thus, the type id

To load the parkingAreas into duarouter you need to set option

Hello Jakob,
I tried something similar to your example:
It is observed that vehicles assigned to such a line (public transit route)
are indeed taking multiple trips as per the definition and the relative
time values are maintained. Each of these assigned vehicles
