Re: [sumo-user] Help with findIntermodalRoute() results. 
Dear All,

I'm having some issues in using findIntermodalRoute in the right way.

When calling traci.simulation.findIntermodalRoute(stage['from'], stage['to'],
depart=stage['start'], walkFactor=.9)
I always get results such as
Stage(stageType=2, vType='', line='', destStop='', edges=( ~~ very long list of them ~~ ),
travelTime=6488.764000000054, cost=6488.763999999993, length=8211.589999999991, intended='',
depart=-1.0, departPos=0.0, arrivalPos=0.0, description='')
even if I manually checked that the edges are close to a bus line with buses every 10 minutes (*).

(*) It's not realistic, but for testing reason, I have all my bus running for 24h every 10 minutes,
in order to be sure that I have coverage.

The fact that I have depart=-1.0 after I explicitly set a departure time, makes me feel that
something is wrong. I never had this issue before, but it's a while (pre 1.0.0) that I'm not
actively working on this, and I didn't realized that something may have changed until now.

Unfortunately there is no documentation for the function in
http://www.sumo.dlr.de/daily/pydoc/traci._simulation.html, so I have to ask.

Thanks in advance for the help.

Regards,
Lara
