Hello,

it is not possible to define permissions for connections at the moment.

All you can do is controll usage of the connections by changing permissions
on the source or target lane.

SUMO currently does not contain any automation for this.

However, you can control the availability for turns globaly by setting
--no-turnarounds (controlled in detail by further options that start with
--no-turnarounds.).


regards,

Jakob

Betreff: Re: [sumo-user] Illegal U turns to reduce travel time



Hi Jakob,



Thanks! After importing from OSM, all vehicle types can do U turn at every

junctions and I can't find any turning connection parameters in NetEdit to

modify the permissions. Any guides to allow only specific vehicle type to do

an U turn instead of all vehicle types?



Thanks,

CG
