本研究考察了志愿地理信息（VGI）在日本全国地理空间中监测和探索自行车活动的有效性。从流行的VGI网站上收集了16,945条自行车活动的GPS轨迹，用于活动映射和共享。分析通过三个主要阶段进行；(1)网络用户发布的VGI特征；(2)时间序列格局；(3)汇总水平上骑行活动的空间分布。在第一个分析中，VGI中有1419个用户，每个用户发布的帖子数达到100的用户发布的VGI数量约占总数的53%。在时间序列分析中，日本的春季和秋季等适合户外休闲的季节，自行车活动较多，而冬季则相反，自行车活动较少。在GPS轨迹的空间分布上，虽然GPS数据覆盖了日本全境，但集中在人口较多的大都市地区的趋势较为突出。
This study examined the effectiveness of volunteered geographic information (VGI) for monitoring and exploring cycling activities in the nationwide geographical space in Japan. A total of 16,945 GPS trajectories of cycling activities was collected from the popular VGI website for activity mapping and sharing. Analysis is conducted through three major phases; (1) Characteristics of VGI posted by online users, (2) time series patterns and (3) spatial distribution of cycling activities at an aggregated level. In the first analysis, 1,419 users were found in the VGI, and the number of VGI posted by users whose number of posts per user was up to 100 is about 53% of the total. In the time-series analysis, the comfortable seasons for outdoor recreation in Japan such as spring and autumn produce many cycling activities, but conversely, activities are reduced in winter. In the spatial distribution of GPS trajectories, though GPS data cover the whole of Japan, the tendency to concentrate in large metropolitan areas with high populations was prominent.
