[sumo-user] Compute Fuel Consumption and CO2 emissions in Traci

[Do Duc Le <doducle@xxxxxxxxxx>]

Hi all,

I want to compute the fuel consumption and CO2 emission and I do that 
with traci.vehicle.getFuelConsumption(veh) and 
traci.vehicle.getCO2Emission(veh), but the computed values are too high, 
e.g I have 75 Litre / 100 km for fuel consumption for traffic in cities 
(maxspeed 55 km/h). Also this should vary for different step-length, but 
it doesn't matter if I use a step-length of 0.1 or 0.2, at each 
simulation step I get the same value for one vehicle about 1.06 for fuel 
consumption and 2473.8 for CO2 emission. As a result I get about double 
the fuel consumption and CO2 emission for step-length 0.1 as for 
step-length 0.2, the total driven distance is about the same in both cases.
Can someone help? Is this the correct way to compute fuel consumption 
and CO2 emissions?

Best regards,
Duc
