Abstract:
In recent years, there has been dramatic enhancement of computation power, rapid development in Geographic Information System (GIS), three-dimensional (3D) computer graphic and virtual reality technology. Digital topographic and mapping data are also widely available and ultilised for various applications. This had facilitated the rapid advancement in road traffic noise assessments and data presentation. Two-dimensional (2D) and even 3D noise mapping over a large geographical area has now become a much more manageable task. Hong Kong has seized the opportunity in developing advanced 3D noise modelling techniques and noise mapping in support of it's policy evaluation and formulation initiatives. State of the art 3D GIS tools, interface applications with large scale noise modelling software, sophisticated information technologies for data streaming and rendering were tried out in Hong Kong. 3D noise models were presented in meeting and uploaded to web site for consultation with local residents to encourage public participation. Also, the techniques were employed to more accurately determine the noise exposure of the population, the eligibility and overall benefits of applying low noise road surface to road sections in a large area, the determination of noise exposure of residents in support of social survey.
