Re: [sumo-user] randomTrips for multiple vTypes

Dear Jakob,

Thank you very much for helping!

I tried the second approach you mentioned before I asked. But when I tried it, I have following addition xml file. 
<vTypeDistribution id="typedist1" >
<vType id="vTypeCar" maxSpeed="35" vClass="passenger" length="4.5" guiShape="passenger" probability="0.9"/>
<vType id="vTypeBus" maxSpeed="30" vClass="bus" Length="14.63" guiShape="bus" probability="0.1"/>
</vTypeDistribution>

Could you help to clarify how to set type attribute? I tried randomTrips.py --trip-attributes="type=\"typedist1\"" But it doesn't work.
I think I need a list of parameters which can be put into --trip-attributes="" but I didn't find it.

Thank you very much! I appreciate it very much!

Have a good day!

Sincerely,
Dayuan

If you wish to generated multiple types you either have to
- run randomTrips multiple times with a different type attribute (you also need to set the --prefix option to ensure all vehicles have distinct ids).
- put the types into a vTypeDistribution and put the distribution id into the type attribute

Dear Jacob,

Thank you very much for your helping!

I actually checked the webpage you sent before I asked. It mentions the case with one vType: "<SUMO_HOME>/tools/randomTrips.py -n input_net.net.xml --trip-attributes="type=\"myType\"" --additional-file type.add.xml
   --edge-permission passenger"

I'm wondering what if I have multiple vTypes defined in addition.xml. I tried to change it to "…--trip-attributes="type=\"myType1 myType2 myType3 myType3\""  …" but it seems it doesn't work. 

Thank you very much!

Have a good day!

Sincerely,
Dayuan

Dear All,

Could anyone help to explain how to use randomTrips to generate trips with multiple vehicles types?
On the official website it mentions "randomTrips.py --vehicle-class bus".
But I have multiple vehicle types defined in my addition.xml file. 

I tried using vehicle type distribution but it doesn't work. The output rou.xml still doesn't have type attribute for vehicles. 

Thank you very much! I appreciate it very much!

Have a good day!

Sincerely,
Dayuan
