Collision detection for bicycle and pedestrian exchange GPS location in smartphone

In recent years, the number of people who uses bicycle has been increased. With these, accidents between bicycles and pedestrians have increased accordingly. Generally, these accidents will occur at blind corners where pedestrians have difficulty to see them. In the cities, more effective and smart way for decreasing the accident is expected. We proposed a system that warns with the calls of smartphone for both the pedestrian and people who ride on the bicycle on the corner if they approach and expect danger of collision. The system we proposed and have implemented uses two-way communication method that is provided by the GPS location information commonly installed within the smartphones. In this paper, we will describe the purpose, design and implementation, and show the experimental results and discussion of the future vision.
