Re: [sumo-user] MAROUTER: input flow and scale issue
The issue with fromJunction and toJunction is now fixed.

The route costs in marouter are travel times multiplied with a traffic-density dependent capacityConstraintFunction.
The actual travel time can only be guessed at at this point since it will depend on vehicle interactions. To compute empty-network travel times you can pass the marouter-routes to duarouter. If you need more realistic traveltimes, simulate with sumo.

True, the scale parameter works perfectly fine. I am not sure if I was testing it on a nightly build version of 1.8.x, but now on 1.9.0 it works.
However, the fromJunction - toJunction option for route files is not working, while it works perfectly fine in DUAROUTER. Moreover, for the output of MAROUTER  I was under the impression that route costs are travel times (since the weight attribute is by default traveltime) but I get values that are much larger than traveltime,  maybe distance in meters? Is this cost in MAROUTER modifiable i.e. to get travel time of each trip? 

Best,

Scaling route file input is supposed to work since 1.9.0 (and it's working in our test). Can you send me a minimal failing example for 1.9 or later?

Dear all,

I am running MAROUTER on an extremely large network and have only 1% of the real demand, which means I have to scale it by a factor of 100. However, when I define demand as route file and apply the --scale option, it has no impact on the number of loaded vehicles. When I try to define demand as flows, no valid vehicles are loaded. Any suggestion on how to scale demand when using MAROUTER? or even a better way to downscale capacity (similar to MATSim)? 

Best,
Sasan
