CO2 reduction thanks to improved traffic flow

A sustainable reduction of greenhouse gasses is only possible when all parties, technicians, users and operators work together. The infrastructure operators are accused of not doing enough to ensure free-flowing traffic.

This study aims to examine the network of Federal motorways to demonstrate the extent to which more free-flowing traffic enabled by an expansion of the infrastructure will have a positive effect on carbon monoxide emissions. The critical road sections will be identified first for this purpose. For this section it is hypothetically assumed that an extension is performed and a new share of the traffic demand is calculated for the same section. The occurring traffic flow is then included in a new calculation of emissions.

As project partner, the TU Graz calculates emission factors for different traffic conditions on the basis of the most up-to-date emissions calculations for current vehicles.
