R package to estimate public transport emissions based on GTFS data
### Problem Description I have been attempting to install the `gtfs2emis` package in the Azure AI | Machine Learning Studio to utilize cloud computational resources. However, I'm encountering an issue...
There is some info on rail emission factors in this report by the UK government. - Defra (Department for Environment Food and Rural Affairs) and DECC (2013) [2013 Government GHG...
When there are `NaN` speed values in the `transport_model()` ouput and no other valid value, it's not possible to perform a mean average to remove the `NaN` . In such...
Emission factor models are regularly updated, often with new emission factors data sets every year. We need to think carefully how will deal with these updates. Here are three questions...
This could either be available for through a new `emis_road()` function OR through `emis_summary(by='road_segment')`
SPN units can be either "SPN23 [#/km]", "SPN23 [#/kWh]" . This behavior also happens with PM Exhaust. Check `data-raw/ef_europe_emep_db.R`
- [ ] fix emission factors for g/kWh units - [ ] check adjust EF considering reference year
Availability of CARB’s EMFAC2021 Technical Document and a Model Update (v1.0.1) https://content.govdelivery.com/accounts/CARB/bulletins/2d48287
Few articles I've looked at seem to be using the IVE model as an emission factor source. Check whether this is proper EF. If true, create a function to import...
