The Method of Urban Safety Analysis and Environmental Design

Recent rapid development of information technologies, i.e., Internet, Mobile Computing, Remote Sensing, Virtual Reality, etc., have changed our social life in various fields. This remarkable innovation also affects the field of urban safety planning or disaster mitigation. Cooperating with these latest information technologies, some human activities for disaster mitigation could be shifted into a new paradigm. Especially, GIS technology will be an effective means, because the spatial viewpoint is indispensable not only for the field of physical environment like urban planning but also for human activities. In fact, a lot of researches with GIS have been carried out since the 1994 Northridge Earthquake and the standardization of spatial data infrastructure as ISO/TC211 is globally under development. In the field of architectural design, some architects have discussed new possibility of Cyber City or Cyber Architecture. However, the expected new concept of cyberspace might be only artistic expression on the monitor without awareness of urban problems in the real world. Linking the real world and the cyberspace together to solve the concrete urban problem, the new life style in the IT era will be realized.

Based on the above social background and the previous research, Murao proposed a method named MUSE (the Method of Urban Safety Analysis and Environmental Design) to analyze a city from the viewpoint of urban safety.

It might be difficult for us to recognize differences among cities with physical elements. Kevin Lynch proposed the method called gThe Image of the Cityh to consider the differences between Boston, Jersey City and Los Angeles. In his theory, Lynch classified physical elements of cities into five types and analyzed the cities using the idea called imagability, as shown in following Figure. These five types of elements which were gpathsh, linear elements on which people can pass, such as like streets; gedgesh, other linear elements which people cannot cross, like coasts; gdistrictsh, areas that people recognize to be identical; and gnodesh, important intersections and symbolized glandmarksh in the city. The proposed method MUSE was an experimental attempt to analyze cities visually using urban physical elements.
