Prospect for the Method of Urban Safety Analysis and Environmental Design
Pragmatics
Syntactics is to recognize the social activities in a city through a computer monitor. How people
deal with data or information in the social real life should be considered in Pragmatics field.
One of the final goal of this stage might be realization of Augmented Reality (Feiner et al.,
1999) for disaster mitigation, in which people can get useful information of real objects in a
person's presence through HMD (Head Mounted Display). Construction of a 3D Digital City
Database is indispensable for it. One of the important subjects of this field is how automatically
the spatial data could be updated according to the change of a city. Some information
technologies like remote sensing, laser scanning, and positioning system can be helpful to solve
the problem. The future vision in the field of disaster mitigation is shown in Figure 5. Figure 5
(a) is the utility data for residential buildings with its location projected on a monitor. Using this
application, it is easier to find out the hidden damaged part of the utility after an earthquake.
Figure 5 (b) shows the real-time traffic information on a car window based on the dynamic
simulation described in 3.3. This will be useful for local governments or the public to grasp the
traffic condition of a city. Figure 5 (c) shows the emergency information on a hospital just after
an earthquake (e.g., the number of available beds, the number of doctors on duty, etc.). Figure 5
(d) is the image of the evacuation area led by HMD. The vision, which indicates a new
relationship in the 21 st
century among information, human activities, and disaster mitigation,
will be realized through the three stages by the linkage of the latest information technologies.

Conclusions
The authors proposed a method named as MUSE (the Method of Urban Safety Analysis and
Environmental Design) to analyze a city from the viewpoints of urban safety. In MUSE, some
urban physical elements are defined as parts of an organic system in GIS to analyze or recognize
urban phenomena. Also, a future vision in connection with disaster mitigation was suggested. In
this paper the prospect for MUSE was described. The comprehensive system of MUSE and the
information technologies to realize the vision was named MUSE System. This system consists of
three fields, namely, Semantics, Syntactics, and Pragmatics. Semantics is the field in relation to
the classification and the definition of spatial data. Syntactics deals with the relationship among
the spatial data and other elements (i.e., time, location, and social systems). Pragmatics is the
field in connection with the application of the information to the real social life for people. The
vision, which indicates a new relationship in the 21 st
century among the information, human
activities, and disaster mitigation, will be realized through the three stages by the linkage of the
latest information technologies.
