A SOOA Based Distributed Computing Mechanism for Road Traffic Noise Mapping

Current traffic noise mapping systems are not ideal for distributed computing in dynamic network. This paper investigates the approach and mechanism of distributed noise map generation based on Service Object Oriented Architecture (SOOA). Service Oriented Computing Environment (SORCER) is employed to build a highly flexible distributed network services space. After that, a SOOA based computer aided noise mapping system is presented. For this system, the procedure of traffic noise mapping, the data structure of sound objects, the tasks management mechanism, and the calculation services building are introduced in detail. At last, this paper introduces a real traffic noise mapping project to demonstrate the mechanism and the system. This system aims to enable asynchronous distributed noise mapping generation with ease of alternative calculation services, reduced computing cost, and improved resolution quality.
