Rendering of Dynamic Road Traffic Noise Map based on Paramics

Abstract

Traffic flow is simplified as equal-interval line source in traditional road traffic noise prediction models. The prediction results of these models are non-dynamic and can only be used to render the static noise maps. This paper performs the dynamic simulation of road traffic noise by integrating traffic micro-simulation technology, noise emission and propagation calculation, and accomplishes the dynamic rendering of traffic noise distribution based on Paramics platform. By designing and developing Paramics plug-ins, the dynamic traffic noise map is generated by real-time rendering of the spatial and temporal noise distribution data through the traffic simulation. High validation is indicated from the study case of Zhujiang New Town in Guangzhou.
