Typical hourly traffic distribution for noise modelling

A study was conducted to develop a hourly distribution of traffic in Ontario, Canada, to formulate a noise model. It was demonstrated that the hourly traffic distribution was empirically derived. Data was gathered from the provincial and local levels of government across Ontario, to develop the traffic distribution. Significant attention was paid, to represent the widest possible variety of roads, by gathering data from cities, towns, and municipalities in all regions of the province. Each region within the province was requested to send data sets, reflecting the diversity of road types within the province. The traffic distribution represented rural, collector, arterial, and controlled access roads. Each of the data sets was accumulated, using automated counters.
