Traffic Data Provider is used to predict the car density on each street. The data arriving in real time reports the average speed on each street and at Bettair we use this information to calculate the density of vehicles on the stretch of street, with machine learning algorithms and graphs, which are built on the historical data.
For the estimation of emissions we use the observations obtained from the Bettair node data. To do this, we look for a constant emissions profile in time and space. What is done is to estimate an emissions profile for each type of street (service, residential, tertiary, secondary, primary, highway…) and each hour of the day.
