Description

Emission factors from MOtor Vehicle Emission Simulator (MOVES)

Data.frame of emission factors for buses based on values from the MOVES3 Model. Estimates expressed in units 'g/km'.

Usage

ef_usa_moves_db

Format

A data.table:

pollutant

character; Pollutants: CH4 (Methane), CO (Carbon Monoxide), CO2 (Carbon Dioxide), EC (Energy Consumption), HONO (Nitrous Acid), N2O (Nitrous Oxide), NH3 (Ammonia), NH4 (Ammonium), NO (Nitrogen Oxide), NO2 (Nitrogen Dioxide), NO3 (Nitrate), NOx (Oxides of Nitrogen), PM10 (Primary Exhaust PM10 - Total), PM25 (Primary Exhaust PM2.5 - Total), SO2 (Sulfur Dioxide), THC (Total Gaseous Hydrocarbons ), TOG (Total Organic Gases) and VOC (Volatile Organic Compounds)

fuel_type

character; Type of fuel: 'D' (Diesel),'G' (Gasoline),'CNG' (Compressed Natural Gas).

reference_year

Numeric; Calendar Year between 2015 - 2022. Year in which the emissions inventory is estimated.

model_year

numeric; Model year of vehicle.

lower_speed_interval

units 'km/h'; Represents the lower value of the speed intervals; The speed intervals are " - 2.5", "2.5 - 7.5", "7.5 - 12.5" , "12.5 - 17.5", "17.5 - 22.5", "22.5 - 27.5","27.5 - 32.5","32.5 - 37.5" ,"37.5 - 42.5","42.5 - 47.5","47.5 - 52.5","52.5 - 57.5", "57.5 - 62.5" , "62.5 - 67.5", "67.5 - 72.5", and ">72.5" mph (miles/h).

upper_speed_interval

units in km/h; Represents the upper value of the speed intervals. The speed intervals are analogous to lower_speed_interval above.

source_type

character; Type of vehicle, which currently has only "Transit Bus".

id_speed

integer;it caracterizes the types of vehicle speeds.
