Creating a proactive decision-support environment in managing road traffic noise

摘要

Properly designed decision support environments encourage proactive and objectiveuddecision making. The work presented in this paper inquires into developing auddecision support environment and a tool to facilitate objective decision making inuddealing with road traffic noise. The decision support methodology incorporates trafficudamelioration strategies both within and outside the road reserve. The project isudfunded by the CRC for Construction Innovation and conducted jointly by the RMITudUniversity and the Queensland Department of Main Roads (MR) in collaboration withudthe Queensland Department of Public Works, Arup Pty Ltd., and the QueenslandudUniversity of Technology.udIn this paper, the proposed decision support framework is presented in the way of audflowchart which enabled the development of the decision support tool (DST). Theudunderpinning concept is to establish and retain an information warehouse for eachudcritical road segment (noise corridor) for a given planning horizon. It is understoodudthat, in current practice, some components of the approach described are already inudplace but not fully integrated and supported. It provides an integrated user-friendlyudinterface between traffic noise modeling software, noise management criteria andudcost databases.
