Re: [sumo-user] help

[Daniel K. <d.k...@go...>]

Hello,

please ask questions to the mailing list.

SUMO has some options which force the route computation using the algorithm
described in the paper.

--device.routing.probability FLOAT  The probability for a vehicle to have a
routing device

--device.routing.period INT         The period with which the vehicle shall
be rerouted

--device.routing.adaptation-weight FLOAT  The weight of prior edge weights.

So, --device.routing.probability defines how many of the vehicles shall be
routed using this algorithm (0-1, default: 0); --device.routing.period
defines how often a new route should be computed (in s; default 0, only at
the begin I  think); --device.routing.adaptation-weight describes how the
weights shall be updated.

sincerely,
Daniel
