The package requires two main\ninputs: i) Public transport data in the GTFS standard format;\nand ii) Some basic information on fleet characteristics such as\nfleet age, technology, fuel and Euro stage. As it stands, the\npackage estimates several pollutants at high spatial and\ntemporal resolutions. Pollution levels can be calculated for\nspecific transport routes, trips, time of the day or for the\ntransport system as a whole. The output with emission estimates\ncan be extracted in different formats, supporting analysis on\nhow emission levels vary across space, time and by fleet\ncharacteristics. A full description of the methods used in the\n'gtfs2emis' model is presented in Vieira, J. P. B.; Pereira, R.\nH. M.; Andrade, P. R.
