[sumo-user] AW: .CFG vs netconvert

[<Dan...@dl...>]

Hello Fahd!

Well, actually I do not know what version you use, but I suppose that
you are not using sources from the CVS, am I right?

Ok, the point is that NETCONVERT treats nodes where only one road (and
two roads if they are reconized as one bidirectionaly road) comes in and
out AS DEFAULT. The geometry of edges is still kept in such cases. There
is an option to shut this behaviour off named "--no-node-removal" and
this option is set within your configuration file:
<process>

<no-node-removal>x</no-node-removal>

</process>

So if you want your command line call to do the same as the
configuration file you should write:

netconvert -n box4l.nod.xml -e box4l.edg.xml -o box4l.net.xml
--no-node-removal

I know that many people had problems with this and so in the next
version - 0.9.3 - this behviour is turned off as default and nodes will
be only removed if one passes a special option. The reason why I did
this behaviour as default, is because you can speed up your simulations
by reducing the number of streets to visit each time step when using it.
Still, the documentation was not that good, it has been improved and
I'll put it online in the next few days.

To the routes: within the examples most of the routes were generated by
hand because of the very small sizes of the networks. Normally, we build
a trip table which describes where and when vehicles are emitted and
which destination they want to reach. These trip definitions are then
passed to DUAROUTER.

It's described in
http://sumo.sourceforge.net/docs/gen/user_chp05.shtml#user_chp05-own_rou
tes-tripdefs.

bye,

Daniel

	Hi Daniel,=20
=09
	I dont know if it is a bug or my mistake but I thought I would
discuss it with you. I was working with example in
\data\examples\simple_nets\box\box4l. I used=20
=09
	netconvert -n box4l.nod.xml -e box4l.edg.xml -o box4l.net.xml
=09
	and
=09
	netconvert -c box4l.netc.cfg
=09
	To generate the .net files, both gave different results. You
might want to try them out yourself. The first one omits the 0 and 4th
node.=20
=09
	I am also having slight difficulty understanding routes, so
could you also let me know how the routes are generated in the examples
are they random or self?=20

	Thanks
