A Local Safety Knowledge Sharing System for Proactive Management by Citizens

In this paper, we describe a local safety knowledge sharing system among the community. Our system makes it possible to share detailed safety knowledge, which includes location and time of fearful, unpleasant, or annoying matters which citizens experience, items of their concrete contents, the way of presenting them, etc. In the system, specification is represented according to each type of information in a simple manner. Our system is based on open source contents management system (Xoops) and utilizes maprelated web services. These features enable citizens to manage and evolve our system to suit the needs of the community. As a result of the field experiment in collaboration with citizen IT (Information Technology) volunteers working in Higashi ward of Nagoya, we confirmed citizens were able to manage our system easily and proactively. This leads to the effective sharing of local safety knowledge among the community.
