Travelling exhibition

[Publication Date: May 2019]

“BrennerLEC OnTour”

In March, the BrennerLEC travelling exhibition got underway. A series of posters inform the population about the first results of the project.

The European project BrennerLEC, co-financed by the LIFE programme of the European Union, aims to create a “low-emission corridor” along the Brenner motorway axis in order to achieve environmental benefits in the areas of air and climate protection.

If you do not yet know the first results of the project, you will have the opportunity to see them thanks to the travelling exhibition that will be set up at the headquarters of the project partners and in a series of public buildings. Provincial buildings, municipal offices, social and health districts, cable-car stations and other public places of great affluence will host information panels on the project in rotation.

The exhibition is composed of 4 posters dedicated to the following topics:

What and how is it monitored?

The experimental section of the Brenner motorway monitors vehicles in transit and their speed in order to estimate emissions of air pollutants, air quality and weather parameters to assess the environmental situation of those living next to the A22.

Who and what travels on the motorway? How many pollutants do vehicles emit?

The proportion of heavy goods traffic on weekdays is about 28%. Foreign vehicles account for 42% of total traffic during summer and public holidays. More than 60% of vehicles are in Euro 5 or 6 class. 76% of the vehicles are equipped with a diesel engine. 54% of nitrogen oxide emissions are generated by cars and vans. The emission of nitrogen oxides from diesel cars increases significantly above 80 km/h. For example, by reducing the speed from 130km/h to 110km/h it is possible to reduce the nitrogen oxide emissions of Euro 5 diesel cars by 30%; CO2 emissions decrease by 16%.

What environmental results can be observed by reducing the average speed?

The data collected by the complex measurement system put in place have shown that reducing the average speed of cars by only 15 km/h results in a 10% reduction in the concentration of nitrogen dioxide (NO2) on the motorway.

How is the dynamic speed reduction managed?

The next developments foreseen by the project aim at preventing pollution situations and queues formation. To do this, a sophisticated management system of the variable message signs needs to be put in place.
