Re: [sumo-user] Disconnected plan for person "0"

Hi,

 

have you tried this?

https://sumo.dlr.de/docs/Tools/Trip.html#automatically_generating_a_vehicle_type

 

„Automatically generating a vehicle type

By setting the option --vehicle-class a vehicle type definition that specifies vehicle class will be added to the output files. I.e.

randomTrips.py --vehicle-class bus (but taxi in your case)”

 

I’m sorry, but I still don’t understand why you keep using taxi device if you already defined all routes for vehicles and persons.

 

Regards,

Giuliana

Hello Giuliana,

 

I tried to use the taxi devices with <device.taxi.probability value="0.25"/> in the sumo configuration, while doing the simulation I am getting the error= 

 

"vehicle "id" with Device.taxi should have vclass 'taxi'  instead of 'passenger' ". 

 

I understand that randomtrip.py is generating vehicles with vclass passenger. But as I used 0.25 taxi device probability in sumo config file, shouldn't it automatically change the 25% vehicles to vclass taxi in the simulation?

 

Is their any way to correct this issue or is it a bug?

 

Regards,

Tonmoy

Hi Tonmoy,

 

I think there is no possibility to do this with the command line, you have to add the device parameters manually. You could assign the device by global options, but I think that’s not what you are looking for (see https://sumo.dlr.de/docs/Definition_of_Vehicles,_Vehicle_Types,_and_Routes.html#devices).

 

There is an important difference between VType/VClass Taxi and the Taxi Device:

 

The Taxi Device (see https://sumo.dlr.de/docs/Simulation/Taxi.html) simulates demand responsive transport (DRT) and you can add this device to any vehicle. This allows a fleet of taxis to serve customer requests based on a configurable dispatch algorithm. So you don’t have to define trips for these vehicles, the algorithm will do this for you. This line “<stop lane="D2D3_1" triggered="person"/>“ is used to keep the taxi waiting at the given lane until the first dispatch is received. No more stops need to be added.

 

If you are looking for a vehicle that makes a specific route and stops to pick up passengers, then you don’t need to use a Taxi device. You can just add stops to the route or vehicle. See https://sumo.dlr.de/docs/Definition_of_Vehicles,_Vehicle_Types,_and_Routes.html#stops.

 

Regards,

Giuliana

Hello Giuliana,

 

Thanks for the fast reply.

 

I wanted to know how to add the param keys in the trip files.

        <param key="has.taxi.device" value="true"/>

        <param key="device.taxi.end" value="3600"/>

 

Normally I use the lower command to generate 10 taxi trips. But I am missing the param keys to keep the taxi's in the simulation. And also how to add stop lanes for different taxi trips? Do I have to add them manually? 

 

randomTrips.py -n gnet.net.xml -o taxitrips.rou.xml --trip-attributes="modes=\"taxi\" triggered=\"person\"" --vehicle-class taxi -e 10

 

Regards,

Tonmoy

Hi Tomoy,

Happy to help J

By command line? If you mean adding more taxis with different stops in the simulation, you can just add more trips with different IDs. For example:

    <trip id="taxi" type="taxi" depart="0.00" from="D2D3" to="D2D3">

        <stop lane="D2D3_1"/>

    </trip>   

    <trip id="taxi2" type="taxi" depart="0.00" from="C4C3" to="C4C3">

        <stop lane="C4C3_1"/>

    </trip>

Giuliana

Hi Giuliana,

 

Thanks a lot for the solution.

 

I have one more inquiry, For multiple taxis how can I add this parameter with different stop edges by command line? 

<vType id="taxi" vClass="taxi" modes="taxi" triggered="person">

        <param key="has.taxi.device" value="true"/>

        <param key="device.taxi.end" value="3600"/>

    </vType>

    <trip id="taxi" type="taxi" depart="0.00" from="D2D3" to="D2D3">

        <stop lane="D2D3_1"/>

    </trip>

Hi Tomoy,

 

You are getting the error "Error: Disconnected plan for person '0' (edge 'C4C3' != edge 'B1B2')" because you are saying that the person has to ride with vehicle 0_0 from 'C4C3' to 'B1B2' and then again from 'C4C3' to 'B1B2' with a taxi, so how does the person get back from 'B1B2' to 'C4C3'?

 

You can make the return trip by taxi:

   

  <person id="0" depart="0.00">

        <ride from="C4C3" to="B1B2" lines="0_0"/>

        <ride from="B1B2" to="C4C3" lines="taxi"/>

    </person>

 

Or you can say that the person should walk to the start edge again and then take a taxi:

 

    <person id="0" depart="0.00">

        <ride from="C4C3" to="B1B2" lines="0_0"/>

        <walk from="B1B2" to="C4C3"/>

        <ride from="C4C3" to="B1B2" lines="taxi"/>

    </person>

 

If you choose this option, you will have to add the pedestrian crossings to your net (https://sumo.dlr.de/docs/Simulation/Pedestrians.html#generating_a_network_with_crossings_and_walkingareas). This can be done using netconvert with the following command:

netconvert -s gnet.net.xml --crossings.guess -o gnet.net.xml

 

I don’t understand why you define fixed routes for the taxis. If you are trying to simulate an on demand/ride hailing service this is not necessary. You can just give the first edge, from where the taxi will wait for a request:

 

<vType id="taxi" vClass="taxi" modes="taxi" triggered="person">

        <param key="has.taxi.device" value="true"/>

        <param key="device.taxi.end" value="3600"/>

    </vType>

    <trip id="taxi" type="taxi" depart="0.00" from="D2D3" to="D2D3">

        <stop lane="D2D3_1"/>

    </trip>

 

Regards,

Giuliana

Hello Everyone,

 

I have been trying to get intermodal routing PERSONTRIPS using different combination of modes=car taxi or taxi car, even after using explicitly defined taxi lines, I am still getting "Disconnected plan for person "0".

 

what should I do to solve this problem?

 

Thanks in advance.

 

P.S. I have attached the files in here.
