Re: [sumo-user] Simulation of GPS Trajectories
|
Hi Alemu,
I see that the dataset you linked to is *very* big. If you are planning to
convert the whole dataset to SUMO routes, then I would recommend that you
use Sumolib, as it is faster than TraCI. Sumolib can locate the nearest edge
from a given gps-coordinate (see [1]). You can therefore iterate through all
your coordinates in a script to get a sequence of edges. You can then parse
those edges as a route file, using Python's xml library.
Hope that helps. BTW, I'm doing exactly this in my project. I can share my
python code with you if you like. Just email me privately.
