Abstract:
Traffic management and traffic design have been issued as the main solutions to reduced problems related to mobility. In relation with noise mapping, traffic simulation is usually based on macroscopic modelling, with e.g. mean speed and flow as output. However, dynamics in terms of acceleration have a strong influence on noise emission. In the current paper, road traffic noise emission is calculated with dynamic traffic as input. A real case, now in planning stage, is used as a setting containing several traffic design alternatives. The resulting total noise emission is calculated for the different traffic and road design solutions by using a microscopic traffic simulation model (VISSIM) combined with a model for noise emission (CNOSSOS-EU). The qualities of the resulting traffic and noise situations are discussed.
