Nowadays, when designing a road intersection, it is necessary to take into account the environmental performances, which are actually considered as relevant as the traditional criteria related to safety, functionality and costs. The aim of this research is both environmental analysis and calculation of pollutant emissions for four different at-grade four-arm intersections (standard traffic-signal controlled intersection, one-lane, two-lane and turbo-roundabout), referring to different traffic flows distribution. The results of this research are summarized by three-dimensional surfaces, which can be a useful tool for the designer to predict the environmental impact that each scheme would cause and choose the most appropriate one
