Re: [sumo-user] Left turn from the shoulder.

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Building a parallel edge is easier but you can do it with an extra lane and a single junction with some care:

- set a custom lane shape for the shoulder so that the cars enter the junction at the correct angle

- set contPos=0 for the left turn because the normal network generation creates an invalid waiting position otherwise

Jakob

Good evening,

I need to simulate the geometry of the intersection shown below. To make a left turn, vehicles wait on the shoulder.

Is there a feature in SUMO to model this type of situation, or is it better to construct an additional parallel edge, effectively splitting the intersection into two?

Sds,

Pedro Oliveira
