摘要：	This Air Quality Further Assessment has been produced by the Transport Research Laboratory (TRL) Ltd for Milton Keynes Council as part of their Local Air Quality Management (LAQM) duties. The Further Assessment focuses on the market town of Olney, Buckinghamshire, where an Air Quality Management Area (AQMA) was declared for annual nitrogen dioxide (NO2) concentrations in 2008. Annual mean concentrations of NO2 were modelled using the ADMS-Roads dispersion model for the base year of 2007 and the future years of 2010 and 2016. The Further Assessment determined that emissions from heavy goods vehicles (HGVs) contributed to at least 50 of the NO2 concentrations at receptors along Bridge Street and High Street South. Modelling confirmed the findings of the 2008 Detailed Assessment, with exceedance of the annual mean NO2 Air Quality Strategy (AQS) objective predicted at relevant receptors along Bridge Street and High Street South in 2007. These exceedances were within the existing AQMA and it was recommended that the boundary should not be amended. Future reductions in emissions of NOX from road traffic have meant that the NO2 AQS objective has been predicted to be met at all modelled receptors in 2016. The report provides recommendations on measures that Milton Keynes Council may consider for inclusion in their Air Quality Action Plan for introduction by the year 2010. Three measures that focused on reducing HGV emissions were modelled, including a complete ban on all HGVs entering Olney, a complete ban on articulated HGVs entering Olney, or restricting HGV access at certain types of the day. A complete ban on all HGVs was shown to result in an average reduction of 10 in annual mean concentrations of NO2 in 2010 compared to the baseline.
