Abstract:This paper contributes a design support system based on cloud-computing type virtual reality (cloud-based VR) for urban planning and urban design. A platform for Cloud-based VR technology, i.e. a VR-Cloud server, is used to open a VR dataset to public collaboration over the Internet. The digital attributes representing the design scheme of design concepts includes the land use zone, building regulations, urban design style, and other design details of architectural design, landscape, and traffic/architectural environment/sunshine/wheather/noise/inundation/tsunami/earthquake/evacuati on simulation. Then practice using this cloud-based VR urban design support system is categorized into three applicable case 'types', synchronized, distributed synchronized and distributed non-synchronized. The effect of the use of this system in urban design and in urban planning processes is evaluated.
In this paper we discuss the technical possibilities of cloud-based virtual reality (cloud-based VR) computing tools for online collaboration in urban planning and design. We first create a digital asset representing our design proposal of a pedestrian bridge in Shibuya, Tokyo. A platform for cloud-based VR technology, i.e., a VR-Cloud server, is used to open the VR dataset to public collaboration over the Internet. The digital asset representing the design scheme of our pedestrian bridge includes buildings, roads, trees and street furniture for the entire urban area. The vehicles and people are designed and inputted into the virtual world of the urban area, in which they run and walk with predefined behaviour scenarios. Users share the VR world by accessing the VR-Cloud servers from remote clients, using cloud communication software to review vehicle and pedestrian crowd simulations and discuss the design concepts. Meanwhile, we compare the advantages and disadvantages of three cloud-based VR tools on their technical support for net collaboration: 1) VR-Cloud; 2) Google Earth; and 3) 3DVIA.
Abstract:Our study targeted representative urban design guidelines to enhance public understanding. In particular, we concentrated on developing a tool for stakeholders to improve their understanding of urban design guidelines determined by related laws and regulations. In this paper, we suggest that Google Earth can not only display a detailed district plan of the urban design guidelines or related documents but can also offer a possible method for stakeholders to experience the planning site from anywhere via the Internet. Stakeholders can refer to other planning projects on Google Earth at the same time. Thus, urban design guidelines can be more intuitive and dramatic to both professional planners and stakeholders.
In Japan, special planning measures are necessary for residential environmental improvement in the Dens ely Built-up Areas. For this planning issue, many res earches currently try to support public participation us ing virtutal reality technology in order that stakeholders can study the complicated planning measures with respect to the suggested planning alternatives represented by a virtual world. In this paper, we present a learning support system using 3D VIR that can easily virtualize a plan alternative in an urban district area, which can promote the stakeholders' understanding for rebuilding in a densely built-up area. A case study has been conducted to help residents to share of image in the Teramachi Area of Kanazawa city.
