Extensional Smartphone Probe for Road Bump Detection

When a wide area disaster like an earthquake is occurred, an immediate monitoring and sharing of traffic situation and road conditions are important for the quick rescue operation at disaster area. A road bump is one kind of condition which is needed to an immediate monitoring and sharing. But currently, because of a road bump detection is done by human visual confirmation and a mechanical measuring of road surface shapes using profile meter, it needs to use many human resources, long lead time and special equipment. In this paper, a road bump detection method is proposed that can be done more easily, which is named Bump Recorder. That is one kind of a extensional smartphone probe which is a smartphone only put on a vehicle dashboard, and the vehicle is driven as usual. At first, for a prototype Bump Recorder in which is used a pedometer, a bump detection principle and actual measurement result, are explained, which was measured at the Niigataken Chuetsu-oki Earthquake in 2007. And next, for the first generation Bump Recorder in which is used a three-dimensional accelerometer that is installed on a smartphone, bump detection logic and an experiment result are explained. At last, for the second generation Bump Recorder in which is a used three-dimensional gyro sensor, is explained.
