Road information collection and sharing system

Walking is an important factor in good health, and people derive many benefits from travelling by foot. However, walking entails risks such as traffic accidents and falls. If people recognize specific risks before walking, then they may avoid such accidents. This paper proposes a road information collection and sharing tool for the public. The proposed system stores passive risks from the properties of the landscape and active risks identified by people. Moreover, it realizes an easy way to access such risk information. When people know and avoid these risks, they will be able to walk safely.
