Model a fleet of electronic taxisbus vehicles?

Hi, 

is there an example of how to connect vehicle type taxibus from drvp with bevs from transenergysim? This is more a Java skill problem.

First i would create a wrapper class (etaxibus) for both vehicle types. But then? My taxibuses are generated from a dvrp_vehicles_v1.dtd and i want some of them to be electric, so they have to drive to a charging station.

Hi,

for an idea how this plugging together may look like, see

https://github.com/matsim-org/matsim/blob/3a94318b38fd6f3f3d8e5b22a7313b176d99e728/playgrounds/michalm/src/main/java/playground/michalm/taxi/run/RunETaxiScenario.java

There is also the Electric Vehicle Contribution, (transenergy) which you can use, but plugging it together with the taxi module may be more complicated.

To send your taxibus to the charger you will end up programming your own optimizer - I suggest you to use JspritTaxibusOptimizer as a starting point. It uses JSprit to solve the VRP. You could add a different last destination and start your charging there.

Bests,

Joschka

Hi,

Just an addition to what already Joschka said.

The ev package for DVRP is here: https://github.com/matsim-org/matsim/tree/3a94318b38fd6f3f3d8e5b22a7313b176d99e728/playgrounds/michalm/src/main/java/playground/michalm/ev. It is a playground, but will be moved to the official DVRP contrib in the future.

Besides driving-related consumption, you can simulate energy spent on AUX (heating, cooling, on-board devices...). Useful if we have taxi drivers waiting at ranks, or bus drivers waiting at the first/last stop.

With ChargingLogic:

https://github.com/matsim-org/matsim/blob/3a94318b38fd6f3f3d8e5b22a7313b176d99e728/playgrounds/michalm/src/main/java/playground/michalm/ev/charging/ChargingLogic.java

you can model/handle queueing at charging stations when there are more vehicles than plugs available.

Best,

Michal
