Re: [sumo-user] Simulate speed variations

[Pedro Oliveira <pedro.engenhariae@xxxxxxxxx>]

Good afternoon,

Thank you very much for the clarification.

The type "a" I used was just for example purposes.

Do we specify the value of type in that field?

Sds,

Pedro Oliveira

1. The file needs to look like this:

<additional>

  <type id="a">
     <restriction vClass="truck" speed="27.89"/>
  </type>

</additional>

2. the netconvert command will only take effect if the network contains edges with type 'a'  (unknown edge types are not added to the written network)

3. instead of modifying the network you can instead call sumo -n original.net.xml -a speed_restriction_edge.xml  (but again, this will only take effect if the network has edges of type 'a')

Good afternoon,

May I adopt the following format:

netconvert --osm my_osm_net.xml -o rede.net.xml -t speed_restriction_edge.xml

In the file: speed_restriction_edge.xml

<type id="a">
   <restriction vClass="truck" speed="27.89"/>
</type>

Sds,

Good morning! How is this procedure done using a text editor?

Sds,

Class-specific speed limits cannot yet be declared in netedit. You have to write the definition with a text editor.

Good afternoon,

I would like to know how to specify in netedit or sumo how to differentiate between different speeds of vehicle classes on the same edge

combining carFollowModel="KraussPS" with different values for maxAccelProfile in different vTypes i.e.

  maxAccelProfile="0 2.6, 27.78 2.0"

  maxAccelProfile="0 2.6, 22.22 0.6"

should do the trick.

Greetings, fellow sumo enthusiasts. We need to simulate an uphill region where some vehicles have different speed variations relative to others. Is there a solution for this analysis?

Thank you in advance.
