ETA is not accurate in Truck Maps. #377

Closed mansi-techindustan closed 4 years ago

mansi-techindustan commented 4 years ago

Hi, After using the Routing options for truck routes , and changing the weight limit we are not getting the accurate ETA. Example : if we are making the routes from 'SACRAMENTO' to 'RENO' with change in Weight-limit so while increasing the weight limit major differences in ETA is shown which is not accurate.

Hi @mansi-techindustan What ETA value do you expect to see? When you change the truck's weight, ETA should be increased?

mansi-techindustan commented 4 years ago

@NazarKacharaba when i am using Weight-limit below than or equals to '7.2574779' while making the routes from 'SACRAMENTO' to 'RENO' it is showing '2 hours 45 mins' and as I am increasing Weight-limit to '7.7110703' or above then it is showing '3 hour 11 min'. Though i have checked my calculations as well.

It is expected behaviour that you see bigger ETA value for trucks to have bigger weight. SDK uses different speed profiles for light, medium, and heavy trucks. Use RouteOptions.setSpeedProfile(SpeedProfile.FAST) to avoid this overestimation.
