abstract = {Recently, global warming is a serious problem all over the world. Japan endeavors to promote using bicycles in order to protect environment. We developed a system for supporting cyclists by using the data from a bike sensor network. Cyclists lose comfort of riding when they need to go through crowded streets. We collect riding information obtained with a gyro sensor attached to handlebars of a bicycle. Based on such information, we then extract riding condition of cyclists. This paper presents the design and implementation of a Human Probe system that can collect and store sensor data to show comfortable cycling routes on a map.},

abstract = {In recent years, it has become important to understand people flow in various fields. However, most of the methods to understand people flow are limited to urban areas, and there are few studies that have been conducted on a nationwide scale using pseudo people flow data. In ad- dition, by using vector tiling technology in data visualization and changing the granularity of the data according to the zoom level, the amount of data can be saved and the processing speed can be improved. Therefore, in this study, we created pseudo people flow data covering about 120 million people on a nationwide scale using the vector tiling technology, and visualized the data to under- stand the actual situation. As a result, the amount of data has been reduced to about 57%, and ef- ficient visualization can be performed with the necessary information displayed according to the zoom level, including rural areas.},
