Re: [sumo-user] Highway scenario AGAIN

[Daniel K. <d.k...@go...>]

Hello Bruno,

no, it's not much time.

You can continue using the OSM map. This should  look better than a highway
edited by hand: Of course, if you need something that runs really straight,
you may set up a map by hand.

For the vehicles, I would advice you to use trip definitions. In the sumo
user documentation you can find on the wiki, a section on "alternatives for
route definitions" (or similar) can be found. Trip definitions allow you to
define vehicle routes by giving the begin an the end edge only, and let the
router compute the complete routes. In your case, you probably need only
routes starting/ending on the network's boundary. You may obtain the edges'
names by right-clicking on the in the GUI (attention: the lane-ID will be
shown, you have to remove the last underline and the number to obtain the
edge ID). This should work. Of course, you probably will need some
iterations to obtain the vehicle density you are interested in.

sincerely,
Daniel
