Hello,
I’m currently using TraaS to interface with SUMO. I am attempting to reroute a
vehicle and hope to make it change path by setting an effort to an edge (I
believe this is the equivalent of setting a ‘weight’ to that edge), this effort
is calculated from the congestion + other metrics.
1.
kTrace();}
}
The simulation runs fine without
‘conn.do_job_set(Edge.setEffort("edgeToSetEffort", 1));’
Also, ‘conn.do_job_set(Vehicle.setEffort("vehicle", 0, 5000, "edge", 1))’ works
fine, however, I’d like to set the effort for the edges globally.
Thanks,

Hello,
I'm unsure on how to dynamically assign routes to vehicles (with each vehicle
having a route which is unique to them) depending on certain conditions (i.e.
traffic jams, congestion). I'm using TraaS to interface with SUMO and need to
react to certain conditions and dynamically assign rou
"departLane=\”best\”” -r routes.xml’, the same
error “Error: attribute value expected” occurs, whereas with multiple
parameters for –trip-attributes produces no error (and subsequently no route
file).
Kind regards,

Hello all,
I’m currently building a small network from OSM -> .net.xml through NetConvert.

Is there a way to make the number of vehicles much greater? I have tried using

I’m currently trying to generate k-shortest paths for each vehicle (which

Is it possible to run traci.simulationStep() at the same time as running other
code, e.g. rerouting code, so that the simulation runs in realtime without
stopping (to perform other duties such as rerouting)?
Thanks,

Hello,
I’m using Traci to interface with SUMO. I’m currently trying to reroute
vehicles based on travel time, to do this I’ve decided to change the vehicle’s
travel time for an edge using setAdaptedTraveltime() and then rerouting using
vehicle.rerouteTravelTime().
I’ve noticed there’s been a fe
Hello,
An observation I’ve had when rerouting many vehicles at once (going through a
list of vehicles and rerouting them one after the other) is that the rerouting
of the first vehicle seemingly takes by far the longest (sometimes being up to
10 seconds), whereas the other vehicles present in t
Hi there,
More of a generic question – when rerouting a vehicle with
vehicle.rerouteTraveltime(), does the vehicle account for traffic as it
currently stands or traffic that it estimates will be there once the vehicle
reaches the point of congestion? E.g. say a vehicle has 2 possible paths it c

Hello,
I’ve ran into an odd behaviour in regards to traci.vehicle.rerouteTraveltime().

current travel times of the edges in the route) - u

Thanks for the swift response.
For this to work must I have set up the trip before runtime, or can I define
the trips during runtime and ask the vehicles to reroute during runtime?
