Abstract: | This paper describes a computer model of the acoustic behaviour of road traffic at the approach to a system of traffic lights. The outputs of this model consist of various acoustic signatures of the traffic at different points along the roadside. These signatures are a good approximation to those determined at real locations under similar conditions. Use of the model leads to a better understanding of the phenomena involved and the derivation of laws as a function of parameters such as traffic flow, speed limits, proportion of heavy vehicles and the traffic light cycles and synchronization. |
