Re: [sumo-user] Taxis leaving Simulation instead of randomCircling

Hi Jakob,


Thank you for the quick reply and especially for solving my problem (adding the parameter solved to issue)!

Best regards,

you have hit upon an hitherto undocumented feature for randomCircling (

Taxis stop randomCircling after 8 hours to prevent overwork (-:

You can make them work for a whole year non-stop by setting

<param key="" value="365:0:0:0"/> 

in the vehicle or flow or the taxi  vType

Hey all,


I’m experiencing troubles using SUMO‘s taxi device when using randomCircling. Taxis are leaving the simulation after a certain amount of time although the option value="randomCircling" is set. As far as I understood, taxis should be circling indefinitely when said option is set?
I tried various scenarios on two machines but the vanishing happens in all of them, independent of the presence of demand. I’ve attached an extremely simple scenario where said problem occurs.

At this point I’m not sure if I did an obvious mistake myself (which I can’t seem to find) or if there’s actually something wrong with the taxi device. I appreciate your help!


Thanks and best regards,
Felix Gotzler
