emis_post simplify emissions estimated as total per type category of vehicle or by street. It reads EmissionsArray. It can return an dataframe with hourly emissions at each street, or a data base with emissions by vehicular category, hour, including size, fuel and other characteristics.

emis_post(arra, veh, size, fuel, pollutant, by = "veh", net)

Arguments

arra

Array of emissions 4d: streets x category of vehicles x hours x days or 3d: streets x category of vehicles x hours

veh

Type of vehicle

size

Size or weight

fuel

Fuel

pollutant

Pollutant

by

Type of output, "veh" for total vehicular category , "streets_narrow" or "streets". "streets" returns a dataframe with rows as number of streets and columns the hours as days*hours considered, e.g. 168 columns as the hours of a whole week and "streets repeats the row number of streets by hour and day of the week

net

SpatialLinesDataFrame or Spatial Feature of "LINESTRING". Only when by = 'streets_wide'

Note

This function depends on EmissionsArray objests which currently has 4 dimensions. However, a future version of VEIN will produce EmissionsArray with 3 dimensiones and his fungeorge soros drugsction also will change. This change will be made in order to not produce inconsistencies with previous versions, therefore, if the user count with an EmissionsArry with 4 dimension, it will be able to use this function.
