Traffic and Environment

Measurement and Simulation Air Quality - Ventilation and Safety of Road Tunnels


Objective of this research area is to investigate and manage the interrelated processes of emission and dispersion of airborne pollutants with an emphasis on recording traffic emissions and their dispersion in urban areas. The ambition is to investigate traffic emissions and air quality in order to develop the basis for a sustainable improvement of the quality of life.

An additional focus is set on ventilation, fire safety and environmental issues concerning road and rail tunnels, as well as the testing and application of measuring systems for detecting atmospheric trace elements.


The fields of research in detail:

  • Assessment of emission and fuel consumption from traffic
    • Emission measurements and simulation (road traffic, airplanes)
    • Emission inventories for urban areas
  • Pollution dispersion/environmental assessment studies
    • Dispersion near highways, tunnel portals and in complex terrain
  • Measurement of airborne pollutants
  • Tunnel ventilation and safety
    • Ventilation design for rail and road tunnels
    • Design of ventilation control systems
    • Fire tests
    • Commissioning testing
    • Safety installations for road and rail tunnels



The research area is equipped with mobile containers for monitoring air quality (gaseous pollutants and PM), PM size
distribution), and meteorological parameters including sonic anemometers.
For tunnel measurements gas sensors, wind speed, temperature and pressure sensors including data-loggers and video systems are in use.



Since 2013 the FVT research area traffic and environment is running
a testing center according to ISO/IEC 17025:2007. Currently the
scope of testing comprises the measurement of fine dust fractions
PM10 and PM2.5 as well as on the gases NO, NO2 and O3.
