A critical review of some traffic noise prediction models

摘要

Traffic noise prediction models in the 1950s and 1960s were designed to predict a single vehicle sound pressure level (L_p) at the roadside, These models were models were based on constant speed experiments, the predicted levels then being expressed as functions of speed, and with zero acceleration. Later models were not intended to predict single vehicle levels but to predict the equivalent continuous level (L_eq) for traffic over a chosen period. Still later models predicted (L_eq) under interrupted and varying flow conditions.
