South Dublin County Council N7 Newlands Cross Upgrade Environmental Impact Statement Arup Consulting Engineers • Signal type (refer to Appendix A9.4 and A9.5) • Arrival time (refer to Appendix A9.4 and A9.5) Breeze ROADS was used with CAL3QHCR to predict kerbside CO, Benzene, PM10 and NO2 concentrations in the vicinity of the proposed interchange, where the impact of emissions from road vehicles is expected to be greatest. The background concentrations of each pollutant were then added to the calculated concentrations, to assess the cumulative impact (refer to Section 9.4.2 for details on background concentrations). Receptors were selected based on their sensitivity and their proximity to the proposed interchange (refer to Figures 9.3). The National Atmospheric Emissions Inventory (NAEI) 10 provides a method for calculating vehicle emission factors (g/vehicle per km) by applying year factors and speed factors to a standard set of emission factors. This is calculated for a vehicle mix including both light good vehicles (LGVs) and heavy good vehicles (HGVs). It was considered that the accuracy of this method was suitable for the purposes of this study, because it is based on the same EU vehicle emission standards as apply to Ireland. The calculated emission factors for the proposed interchange are shown below in Tables 9.3 and 9.4 for 2010 and 2025, respectively. December 2007 Page 143
