AB  - This paper describes the development of a model for assessing TRAffic Noise EXposure (TRANEX) in anopen-source geographic information system. Instead of using proprietary software we developed ourown model for two main reasons: 1) so that the treatment of source geometry, traffic information (flows/speeds/spatially varying diurnal traffic profiles) and receptors matched as closely as possible to that ofthe air pollution modelling being undertaken in the TRAFFIC project, and 2) to optimize model performancefor practical reasons of needing to implement a noise model with detailed source geometry, overa large geographical area, to produce noise estimates at up to several million address locations, withlimited computing resources. To evaluate TRANEX, noise estimates were compared with noise measurementsmade in the British cities of Leicester and Norwich. High correlation was seen betweenmodelled and measured LAeq,1hr (Norwich: r ¼ 0.85, p ¼ .000; Leicester: r ¼ 0.95, p ¼ .000) with averagemodel errors of 3.1 dB. TRANEX was used to estimate noise exposures (LAeq,1hr, LAeq,16hr, Lnight) for theresident population of London (2003e2010). Results suggest that 1.03 million (12%) people are exposedto daytime road traffic noise levels  65 dB(A) and 1.63 million (19%) people are exposed to night-timeroad traffic noise levels  55 dB(A). Differences in noise levels between 2010 and 2003 were on averagerelatively small: 0.25 dB (standard deviation: 0.89) and 0.26 dB (standard deviation: 0.87) for LAeq,16hrand Lnight.
