[HTT25-P03] Geospatial analysis of moving routes of bicycles using probe data
Keywords:Bicycle, Probe data, GNSS, Spatial analysis
Along with the probe data of bicycles, topographic environments and land use data were collected for five cities including Melbourne (Australia), New York (USA), Austin (USA), Chicago (USA), and Paris (France). Spatial analysis was performed using these data. Regarding the bicycle trajectory, the three points, including commuting use, weekend use, and use ratio on weekdays and weekends, were focused to be compared with the urban structure. Characteristic features of bicycle use for each city, as well as common features among the cities, were clarified: for instance, in Melbourne, commuting users tend to pass curved roads near parks more frequently rather than straight roads. Also, the use of roads in suburban areas is more frequent in weekends. Like this, it is observed that the frequent use of bicycles is found in or near parks, or characteristic topographical environments such as rivers and ridges, suggesting that the bicycle use strongly depends on the urban environments. Classification of bicycling networks is possible for different existing urban structures. It was also shown that the use ratio of bicycles in the central and peripheral areas is different for each city. These findings can be used for promoting future bicycle policies, including the construction of a wide-area bicycle network that incorporates existing urban structures, and optimal routes and connection distances.
