Estimate of traffic emissions through multiscale second order models with heterogeneous data

<p style='text-indent:20px;'>In this paper we propose a multiscale traffic model, based on the family of Generic Second Order Models, which integrates multiple trajectory data into velocity function. This combination second order macroscopic model with microscopic information allows us to reproduce significant variations in speed and acceleration that strongly influence emissions. We obtain accurate approximations even few data. The proposed approach is therefore computationally efficient highly tool for calculating quantities estimating emissions.</p>
