Does NetEdit currently have any way to create or edit a Simpla platooning

Re: [sumo-user] Different results on different machines

[Jakob Erdmann]

Hi Karl,
we are aware of platform-specific behavior (windows / linux) in regards to
floating point operations. Another way to get differences is by using
slightly different versions of third party libraries on different
platforms.  The proj library that handles coordinate conversions behaves
slightly different between versions and this can affect the simulation.
Also, there are differences in generated random numbers between python2 and
python3 which might play a role when running traci scripts.

regards,
Jakob

Re: [sumo-user] Different results on different machines

[Schrab, Karl]

Hi Jakob,

Thanks! Anyhow, I doubt this is the main problem, as I add all vehicles via 
TraCI.  Also, I always get the same results on the same machine, but different 
results on a second machine, so I would exclude the RNG as a culprit.
I’m not that deep into C++ and compiler stuff, but could precision / rounding / 
comparison of doubles play a role and result in different behavior on different 
machines?

Kind regards,
Karl

We are currently experiencing a very weird issue related to counting vehicles

Re: [sumo-user] make the network circular in a non-geometrical way

[Jakob Erdmann]

Hello,
I suppose the FAQ advice for creating non-geometrical loop was misleading.
My suggestion is, that you define an edge with sensible geometry (i.e. a
big detour loop around the central intersection (so the geometry will look
fine) and then declare it's length to be 0.1m.
Reason: netconvert will always compute geometry and if edges intersect at
strange angles the network will look like a mess. (An alternative would be
to manually define the geometry of the border junctions.

Jakob

Dear  all,

I have one question while I was using the  *duaIterate.py *to generate the
routes in my simulation. I would like to improve the probability of some
edges to be chosen in some routes generated. How could  I give more chances
(like change the weight ) to some edges in one network while using
duaIterate.py?
any kindly help will be appreciated!
