Re: [sumo-user] Edge lenght

[Michael Behrisch <oss@xxxxxxxxxxx>]

Hi,
the way to do it is:
net = sumolib.net.readNet('myNet.net.xml')
for edge in net.getEdges():
    if edge.getID() == myedgeid:
        length = edge.getLength()

You can parse the net directly but then you do not always have a length
attribute (only if there is a user defined length for the edge).

Best regards,
Michael

I looked a little through the internet but I got a little bit confused about the answer I found. How can I retrieve the length of a particular edge?
