2 What is natural surveillance ? Natural surveillance means to secure urban areas against criminal offenders under observation by building occupants and passersby in natural way. Jacobs (1961) first referred to the effectiveness of natural surveillance. Crowe (1991) classified surveillance as three types; natural, organized, and mechanical. Natural surveillance is considered most important. References Jacobs, J. (1961 The Death and Life of Great American Cities. New York: Random House. Crowe, T.D. (1991 Crime Prevention Through Environmental Design: Applications of Architectural Design and Space Management Concepts. Boston: Butterworth-Heinemann. Surveillance Classification Crowe, 1991 MechanicalOrganized Natural

3 Team BIM Japan How to simulate natural surveillance ? Referring to Koike et al. (2008), we Team BIM Japan assumed that level of natural surveillance (t) can be defined as the amount of agents eye fixation at that time. –Agents: agents of persons who exist within the allocated site (Area 6); such as public space users, residents, etc. –We simulated traffic lines of agents with building EXODUS including traffic schedule of agents, and natural surveillance with 3ds MAX. –Agents eye fixation can be modeled as lightness in the space by using unidirectional lighting model in 3ds MAX. Elements of agents –Traffic schedule Time Start point End point –Eye fixation Range Sight References Koike et al. (2008) Development of the Models Showing the Extent of Natural Surveillance by Using Light Projecting Method, AIJ J. Technol. Des., Vol. 14, No. 27, , Jun., Natural Surveillance Eye fixation can be modeled by using unidirectional lighting model in 3ds MAX Simulation level of natural surveillance (t) can be defined as the amount of agents eye fixation at that time.

5 Team BIM Japan Result: traffic line

6 Team BIM Japan Result: natural surveillance 6-12 (24h)

7 Team BIM Japan Security Planning through Simulation Team BIM Japan

8 Security Planning Find crowded areas, and control traffic lines –Add CCTV at crowded areas Find areas where natural surveillance is not enough, and add surveillance –Add mechanical surveillance (CCTV)

9 Team BIM Japan Security planning: traffic line Add mechanical surveillance here

10 Team BIM Japan Security planning: natural surveillance Add mechanical surveillance here 6-12 (24h)
