%description
A bottom up model to estimate the emission levels of public transport
systems based on General Transit Feed Specification (GTFS) data. The
package requires two main inputs: i) Public transport data in the GTFS
standard format; and ii) Some basic information on fleet characteristics
such as fleet age, technology, fuel and Euro stage. As it stands, the
package estimates several pollutants at high spatial and temporal
resolutions. Pollution levels can be calculated for specific transport
routes, trips, time of the day or for the transport system as a whole. The
output with emission estimates can be extracted in different formats,
supporting analysis on how emission levels vary across space, time and by
fleet characteristics. A full description of the methods used in the
'gtfs2emis' model is presented in Vieira, J. P. B.; Pereira, R. H. M.;
Andrade, P. R. (2022) <doi:10.31219/osf.io/8m2cy>.
