Dear Matsim Users,
I'm simulating the public transport but, when I visualized on Via, the trains are drawn/colored/labeled as cars, and I don't understand why.

These are extracts from my input and output files


INPUT - CONFIG

<module name="scenario" >

Re: Public Transport: trains labeled as cars

Dear all

I'm simulating the public transport but, when I visualized on Via, the trains are drawn/colored/labeled as cars, and I don't understand why.

This is indeed the case, and has to do with some historical reasons in MATSim. As Haitam pointed out, it is a known issue and we hope to fix it for the next release.

When I added pt mode to the QSim Main Modes, I ended up with two exceptions:

“pt” is the mode for the passengers to use Public Transport. The transit vehicles should actually use a different mode, more something like “bus”, “train”, “subway”, “tram”, etc.

In the transitSchedule.xml, one can define a transportMode, see http://www.matsim.org/docs/tutorials/transit. Ideally, MATSim would use that mode, but instead currently just uses “car” every time.

But, Via can fix this! These are the steps to follow:

- Load the Network, Vehicles, TransitSchedule and TransitStats layer in Via (requires the transit plugin for Via, included in the educational licenses).

- At the TransitStats-Layer, click on the triangle in the upper right to get a menu with additional commands. Select “Merge TransportModes to Vehicles”, as shown in the picture:

Via will then overwrite the “car” mode of transit vehicles with the transportMode specified in the transitSchedule.xml.

After that, you can use the correct modes to visualize the different types of vehicles differently.

Hope this helps!

Regards,

Marcel
