Risultati finali

Results on sleep disturbance and cardiovascular risk to different tyre noise psychoacoustic parameters

This deliverable will describe findings from laboratory studies into the effects of the impact of nocturnal tyre noise on a number of critical outcomes of relevance for public health and the genesis of cardiovascular disease. These critical outcomes are blood metabolic biomarkers; physiologic sleep depth and sleep structure; noise-induced awakenings and cortical and cardiac arousals; heart rate variability; blood pressure changes and other indices of autonomic and cardiovascular function; self-reported sleep.

Evaluation of future new policies and mitigation strategies on tyre wear particle emissions

Three scenarios will be considered. The baseline scenario will investigate the possible evolution of the problem assuming a no policy change scenario. The second scenario will examine the feasibility of emission regulation similar to that of exhaust emissions. Finally, the last scenario will examine the possibility to control tyre wear particle emissions through tyre abrasion rate

Dissemination and communication strategy with KPI

A dedicated strategy in regards of dissemination publications workshops conferences and communication social media channels newsletters press releases will be elaborated It is very important to define relevant KPIs to establish a measure for success

Evaluation of future new policies and mitigation strategies on microplastic emissions

Input from the project will allow for a reliable estimate of microplastic emissions from tyres to different environmental compartments. A quantitative and qualitative baseline scenario will be developed considering the possible evolution of the problem in a no policy change scenario. At a next level, prevailing future policy scenarios will be developed based on the objectives, reduction measures, and developments on the abrasion rate method.

Report describing the TWP degradation tests in order to derive degradation kinetics (chemical transformation and fragmentation rates) of TWP in soil and sediment for modelling TWP fate in the environment.

Mid-Term Communication and Dissemination and Liaison summary

Since the project duration is about 36 months midterm reporting is required It helps to give an update on the project progress by the use of dedicated newsletters publications and also conference presentations

Report assessing current available techniques and methods, describing improved sample pre-treatment, thermo-analytical and microscopic methods for quantification and size selective physicochemical characterization of TWP and describing a methodological framework for the measurement of TWP in environmental matrices.

Updated emission model for local and EU scale scenario's

Report describing the updated emissions and fate model as required for quantifying local and EU scale TWP and microplastics. The modelling tool will be demonstrated online.

Evaluation of future new policies on noise emissions

Two scenarios will be considered for tyre noise radiation. The baseline scenario will investigate the possible evolution of the problem assuming a no policy change scenario. The second scenario will examine the feasibility of more stringent noise emission regulations. The effect of tyre noise on the human cardiovascular system and generally in human health will be considered.

Website, project identity and promotional materials

It is important to prepare a sophisticated website that gives an insight to the project activities Also promotional materials such as newsletters or dedicated channels in social media will be prepared

Two Composite Wheel airless tyre prototypes

The deliverable will be one airless tyre prototype designed for driving axles of HGV:s, plus one airless tyre prototype designed for the steering axle of HGV:s. They will be two (2) physical tyres, plus a written document describing these tyres, including their construction.
