Re: [sumo-user] [sumo-dev] Discussion on EV Rerouting with Stationfinder Device

Hi,

 

you can use the Calibrator to trigger vehicle type changes depending on the location. Otherwise you can use TraCI (traci.vehicle.setType). Integrated visualisation can be done at edge level but not beyond... So you effectively have to do some with TraCI and change colours yourselves.

 

Best regards,

Mirko

Hi,
 
Besides the stationfinder, can the Vtype be altered during simulation? What's more, is there any regional data visualisation tool, such as a postal code heatmap showing the traffic density? I have so far implemented it by adding poly.add.xml and using traci.polygon.setColor dynamically.

Hi,

 

you can set the parameter like that but currently it does not have an effect on the stationfinder device. Still it does not take much time to implement it. Can you please have a look whether there are more parameters which shall be altered during the simulation? Then I will implement it within the next few days.

 

Best regards,

Mirko

Hi,
 
Is it possible to change needToChargeLevel using TraCI while simulating? I pre-defined it in the route file but I want to change it. 
 
Best,
Haotian
 
Like this?
for veh_id in traci.vehicle.getIDList():
 charge_level = get_charge_level(current_price)
 if traci.vehicle.getTypeID(veh_id) == "HDC/EV":
 try:
 traci.vehicle.setParameter(veh_id, "device.stationfinder.explicit", veh_id)
 print(f"Vehicle {veh_id} 's stationfinder device is enabled")
 traci.vehicle.setParameter(veh_id, "device.stationFinder.needToChargeLevel", charge_level)
 print(f"Vehicle {veh_id} 's needToChargeLevel is set to" + str(charge_level))
 traci.vehicle.setParameter(veh_id, "device.rerouting.period", "5")
 print(f"Vehicle {veh_id} 's rerouting device is checking every 5 timestep")
 except Exception as e:
 print(f"Failed to update stationFinder parameter for vehicle {veh_id}: {e}")

OK didn't see the last one. Still it should now head to the charging station using the latest binaries.

Hi,
 
I think there are two Test cases in route file. The other two vehicles are defined at the second “Test” position.

Hi,

 

yes but the stationfinder is a separate device and assigned only through the config file using the option --device.stationfinder.explicit. There only one of the mentioned vehicle IDs is present in the route file.

 

Best regards,

Mirko

Hi,
 
The vehicle type of the vehicle reroute is HDC/EV and its battery is defined in types.add.xml

Hi,

 

there are some problems with your scenario.

  • Please be sure that the vehicles actually have the devices assigned (in the routes file there is no vehicle with the ID "EV", but one called "reroute")
  • Then you need to set "device.stationfinder.rescueAction" parameter to value "none" if you want the vehicle to continue traveling with empty battery

There was a small problem with the current stationfinder logic. Vehicles waited until the state of charge had dropped by 10% of battery capacity before checking again. I have changed it such that the vehicle will immediately look for charging stations when it is inserted with very low charge. You'd need either to rebuild from Github source or wait until tomorrow for the compiled binaries.

Regarding the parkingArea: If you mention the parkingAreaID explicitly in the chargingStation definition as explained in the docs, it is assumed the charging points are on the parking spaces. The vehicles will leave the road for the charging process. You just need to load / define the charging station after the parkingArea because one refers to the other.

 

Best regards,
Mirko

Hi,
 
The project is attached. The test cases are in the routes.rou.xml. You can locate them by searching "Test". I think my problem is the enabling of stationfinder and battery devices. It should disappear as default if stationfinder is set correctly.

Hi,

 

could you please check what the result you get without the rerouting device (if possible)? Did you set other stationfinder parameters (because by default vehicles with empty battery AND stationfinder device should be removed from the network)? If the scenario is not too heavy, you may provide it as well to let me check it directly...

 

Best regards,

Mirko

Hi,
 
I am trying the EV rerouting with the stationfinder device. The stationfinder device works on some EVs while the charging station with parking area is originally on their route. I don't need to predefine STOP events. Whereas, the other EVs, which don't have any charging station on the original route, could not reroute to any charging station. 
 
I checked the accessibility and capacity issues of charging stations. To avoid that, I chose a very similar route to that working route, but the similar route takes another edge right before the junction leading to the edge contains a charging station and parking area. In that case, the accessibility is granted. I also made sure that the two EVs don't exist together at any timestep, which means that the first-joined EV finished the trip and disappeared from the network before the later EV joined. What's more, I only set two EVs in the traffic network, others don't have battery devices. And, there is no re-router for road closure during a specific time period.
 
I predefined the hyper-parameter for stationfinder and rerouting devices: 
 
1. .stationfinder.enabled true
2. .stationfinder.needToChargeLevel 0.2
3. .stationfinder.radius 3600
 
1. .rerouting.period 30
 
However, the battery.out and TraCI all showed that the EV with similar route can't reroute to that route to charge and the vehicle kept driving while battery is 0 (default). Would you please give me any suggestions about this? I will provide more detailed information if you need. Looking forward to your reply.
 
Best,
Haotian Li
