In this paper, the authors discuss the technical possibilities of cloud-based Virtual Reality (cloud-based VR) computing tools for online collaboration in urban planning and design. 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 their 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.
