Re: [OSRM-talk] mix kilometers and speed

2014-04-07 Thread didier2020 
sorry for my poor english , the data in my example may be false ...
it's just to add différents amont which are not distance or time
like l/km, highway with fee=yes 
is this possible or already integrated ?

  hi,
  
  i wonder if osrm can mix kilometers and speed to calculate a route
  
  exemple: 
  my car : 5l/100 km with 1l = 1.5 € = 0.075€ for one kilometer
  me : my time can be arround 16€/h
 
 But this is not true for todays cars. Its consumption per km and
 travel speed. Yes - with the current downsizing of motors you get
 much lower fuel consumption on partial load e.g. the citys. But
 driving on the motorway you'll consume the same amount of fuel
 than having a 6 cylinder 3,5l engine. So its not fuel per time
 but fuel per km and road type.
 
  so for a trip of 50 km, and 20 minutes 
  = (50*0.075) + (20/60*16) = 3.75 + 5.33 = 9.08€

 and like this the calculation does not account for car costs like
 value loss, tires, friction, ... and neither for environmental impact
 (CO2 etc)

- CO2 is linear to fuel consumption.
- value loss should be linear to km driven

But a 170hp 1.4l TFSI consumes the same amout of fuel at 180km/h than a
2.5l. It DOES consume a lot less at 30km/h. And thats an optimization
purely done for the measurement cycles driven for consumer comparisons.
