Re: [sumo-user] '--no-internal-links' suppress the insertion of new vehi

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Hello,

the sumo option --no-internal-links switches to a model where the lanes within intersections are no longer used. This reduces the total road space of the simulation and can thereby affect insertion (vehicle insertion can be delayed/fail due to lack of road space).

If you set the netconvert option --no-internal-links when building the network, then the length of "normal" (non-intersection) edges is artificially increased to compensate for the missing road space.

Note, that some types of blockage (jam on intersections) is impossible when using --no-internal-links.

regards,

Jakob

Hi Sumo community,

Hope everyone is safe and healthy.

I encountered an interesting problem where vehicles cannot be inserted to the network if I set '--no-internal-links' to be true. Does this option suppress the insertion of vehicles?

My goal is to keep generating new vehicles using traci.vehicle.add to reach a very congested network. It can be done with internal links, but as expected we will see vehicles entering the intersection and lead to gridlock. When setting '--no-internal-links', the vehicle accumulation is significantly slower and as the figure shows, there seems a limit on the number of vehicles.   

Does anyone have similar experience? Thank you in advance!

Best,

Hao Zhou,
