Frequently Asked Questions
Questions We Hear Most Often
To make vehicle recognition simple, we have compromised between archived fuel efficiency and recognizable characteristics of vehicles. The general size and general shape of vehicles is the most universally recognizable aspect. The need to keep recognition fast and simple, while still adhering to general groupings of fuel efficiency led to the classification we use and ask app users to follow.
It is ok to miss a vehicle here and there – there is normal human error in collecting this data and we have performed many experiments to quantify this error. Hence, understandable missing counts or misclassified vehicles is expected to happen.

About Us
The Hestia traffic app was designed to overcome a chronic challenge in modeling air pollution, heat, and greenhouse gases from traffic volume, traffic flow, and traffic emissions in the "Hestia" model. The Hestia model estimates all sources of air pollution, greenhouse gases and heat, including traffic, buildings, factories, power plants, airports, etc. However, traffic data, the largest source of emissions, is limited. Our aim is to overcome that deficiency with community citizen science collected data.
