This chapter highlights the significance of addressing the problem of growing traffic noise pollution and the use of traffic noise assessment and modelling in this much-needed endeavor. High traffic noise levels have adverse health effects like cardiovascular disorders, speech interference, sleep disturbance, etc. The traffic noise measurements are done for environmental studies, design of buildings, and barrier design, to decide compensation cases in case of litigation by residents and protecting resident population from high traffic noise levels by the pollution control boards and regulatory agencies. The different sources of road traffic noise and contributors to individual vehicle noise have been discussed. The vehicle noise sources include propulsion noise, tire-road interaction noise, aerodynamic noise, gearbox noise, brake noise, and rattle noise. The fundamentals related to traffic noise modelling like traffic noise descriptors, parameters, standard traffic noise measuring equipment, and procedure have been described. A brief description of the statistical pass-by test for vehicle noise has been given. A classification of the diverse traffic noise models (deterministic, statistical, machine learning based, country specific, static, and dynamic) has been presented. Some of the latest traffic noise models like the CNOSSOS-EU model have been discussed. A simple selection criterion to choose a relevant modelling approach based on the regional concerns, geographical requirements, constraints, and availability of tools and skills has been outlined.
