[sumo-user] Person doesn't ride on vehicle added with TraCI

Dear all,

I want to create a bus on demand simulation using sumo. For this reason
I am using TraCI to add vehicles during simulation. The persons are
created statically from xml files. With sumo 0.22.0 everything worked
fine, but with sumo 0.23.0 persons don't ride on the dynamically created
vehicle, even though the vehicle stops at the station. I am using both
line and vehicle id on the lines attribute of person.

Here is the TraCI code for adding the bus:

traci.vehicle.addFull("DEMANDBUS","BUS_ONDEMAND_ROUTE",typeID="BUS_DEMAND",line="2",depart="239")
traci.vehicle.setStop("DEMANDBUS","116895988#2",pos=200,laneIndex=0,duration=20,flags=0)
traci.vehicle.setStop("DEMANDBUS","116895988#4",pos=90,laneIndex=0,duration=20,flags=0)

and here is the person configuration with line:

<person id="person0" depart="150">
<walk from="116895988#2" to="116895988#2" departPos="125"
arrivalPos="195"/>
<ride from="116895988#2" to="116895988#4" lines="2"/>
<walk from="116895988#4" to="116895988#4" departPos="85"
arrivalPos="125"/>
</person>

P.S. I really loved the TraCI API for persons and the show routes
functionality on the GUI.

best regards,
Giannis

Hi Giannis,
vehicles now have a person capacity which needs to be defined in the
vehicle type, see
http://www.sumo.dlr.de/wiki/Definition_of_Vehicles,_Vehicle_Types,_and_Routes#Vehicle_Types,
so please share your type definition as well. The default should be 4
but maybe something is wrong here.

Best regards,
Michael

Hi Michael,

I defined the person capacity on the vType, you can see the xml below:

<vType id="BUS_DEMAND" accel="2.6" decel="4.5" sigma="0" length="12"
minGap="3" maxSpeed="70" color="0,1,0" guiShape="bus" personCapacity="50"/>

also I added it on TraCI code too (I made a mistake previously on stop
duration, now I defined it in milliseconds)

traci.vehicle.addFull("DEMANDBUS","BUS_ONDEMAND_ROUTE",typeID="BUS_DEMAND",line="2",depart="239",personCapacity=50)
traci.vehicle.setStop("DEMANDBUS","116895988#2",pos=200,laneIndex=0,duration=20000,flags=0)
traci.vehicle.setStop("DEMANDBUS","116895988#4",pos=90,laneIndex=0,duration=20000,flags=0)

also I tried to defined it both in the xml and the TraCI, but with no
success.

regards,
Giannis

Hi Giannis,
the new sumo version is much pickier about the exact positioning of the
persons and the vehicles for boarding. The person has to be located at
the exact stop position (well actually between startPos and endPos of
the stop but you can define only the endPos with traci). I opened a
ticket for a more flexible traci API
http://sumo.dlr.de/trac.wsgi/ticket/1717. The person capacity for the
vehicle is useless by the way, it is a vehicle type attribute (the API
is wrong here).

Regards,
Michael

Thanks a lot Michael, I really appreciate your quick reply.

Just to inform you that buses loaded from the xml are working fine,
probably because
the vehicle knows the start and end position of the stop, as you mentioned.

kind regards,
Giannis

Just to get this one right. If you give exactly the same stops via XML
instead of TraCI it works? Or do you have larger stops (meaning startPos
and endPos differ considerably) then?

Hi Michael,

I confirm that with the bus configured in xml, stops and the person
jumps on the bus. Here is the xml code:

**
<busStop id="busstop1" lane="116895988#2_0" startPos="180"
endPos="200" lines="1 2"/>
<busStop id="busstop2" lane="116895988#4_0" startPos="70"
endPos="90" lines="1 2"/>

<vType id="BUS_DEMAND" accel="2.6" decel="4.5" sigma="0"
length="12" minGap="3" maxSpeed="70" color="0,1,0" guiShape="bus"
personCapacity="50"/>

<vType id="BUS" accel="2.6" decel="4.5" sigma="0" length="12"
minGap="3" maxSpeed="70" color="1,1,0" guiShape="bus" personCapacity="50"/>

**
<flow id="BUSLINE1" type="BUS" depart="0" period="300" line="1">
<route edges="116895988#2...319033097#2"/>
<stop busStop="busstop1" duration="20"/>
<stop busStop="busstop2" duration="20"/>
</flow>

**
<person id="person-1" depart="150">
<walk from="116895988#2" to="116895988#2" departPos="120"
arrivalPos="190"/>
<ride from="116895988#2" to="116895988#4" lines="1"/>

</person>

<person id="person-2" depart="239">
<walk from="116895988#2" to="116895988#2" departPos="125"
arrivalPos="190"/>
<ride from="116895988#2" to="116895988#4" lines="2"/>

</person>

<person id="person-3" depart="400">
<walk from="116895988#2" to="116895988#2" departPos="125"
arrivalPos="190"/>
<ride from="116895988#2" to="116895988#4" lines="1"/>

</person>

I remain at your disposal for any clarification.

Hi Giannis,
the case is like I originally assumed, that the stops added via the XML
are much larger than the stops added via TraCI and as such cover the
position of the person while the traci stops don't.
