Re: [sumo-user] When a vehicle can leave the simulation?

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

I you want to retain a vehicle in the simulation you have exactly two options:

- you can make it stay where it is (either on the road or besides the road)

- you can make it continue (but then you should have some plausible destination)

A vehicle may have multiple stop definitions in its route and you can add/remove stops via TraCI.

To prolong the route you may simply set a new destination using traci.vehicle.changeTarget() and the route to that target will be computed automatically if it exists. Obviously, the latter method will not work if your network contains a cul-de-sac without turn-around.

I am afraid I cannot use the idea of adding a stop because the
objectives are stops, the idea was exactly send the vehicle to the
next objective when the stop was over.

To use the "add more edges" idea: I need to
. get the id of last edge in the route (let's call it A)
. load the xml net file,
. look up for the edge tag with the id A
. get its "to" attribute (let's call it D)
. loop up for an edge with the "from" attribute to D
. add the edge to the route

Is that correct? It sounds a bit convoluted. And are we sure I can
always find an extra edge to add?

Cheers,
Paolo
