Hestia Traffic
Help reduce air pollution, traffic congestion, and mitigate climate change by improving information on traffic
This citizen science effort uses the Hestia traffic app to count vehicles on roadways adding information on total vehicle volume and vehicle size makeup. On this website, you can see the data collected, get the traffic app, download data, and communicate with other volunteers

This work is supported by the U.S. Department of Energy, Office of Science, Office of Biological and Environmental Research Urban Integrated Field Laboratories research activity, under Award Number DE-SC0023520.
A component of the Southwest Integrated Field Laboratory (SW-IFL.), the Hestia traffic app will add much needed data to the onroad sector of the Hestia emissions model. This will improve our CO2 emissions, local air pollution emissions, and emissions of heat in the Southwest urban domain.

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.
