Abstract
Bike sharing systems have attained increasing popularity worldwide. They extend the service coverage of public transit by complementing the last-mile service and enabling seamless door-to-door connectivity. Additionally, within a certain range of short-distance traveling, public bike can be a convenient alternative to walking or motorized vehicles. Collectively, bike sharing systems may re-shape the travel patterns of the associated areas. In the long run, the increased short-distance mobility/accessibility due to bike sharing systems may have further influence on the evolution of the activity systems or even land-use schemes in the areas that their services covered. Therefore, it is important to investigate the effect of bike sharing systems on land-use activity. Most studies of bike sharing system planning focused on demand forecasting and the optimization of the locations and capacities of bike sharing stations based on trip characteristics and land use activities. However, spatial elements of the problem have not been fully explored in the aspect of the interactions between land use and activity system dynamics. Further, urban land use patterns possess high heterogeneity over the activity space. A spatial perspective is necessary for investigating the aforementioned effects. Therefore, a general method, Geographically Weighted Regression (GWR) is applied to measure spatial relationship between spatial heterogeneous factors. Hence, within the proposed framework, this study aims to explore the spatial effects of a bike sharing system on land use activities based on the data collected from the operation of the public bike sharing systems in Taipei, Taiwan. Using distance-based public transportation variables, this study firstly investigates the effects of bike sharing systems on land use activities by employing GWR model. Quantitative analyses are conducted on different districts of Taipei City. In addition, this study tries to measure effects of a bike sharing system on extending the service coverage of public transit. Results of this study can be a reference for planning of bike sharing system with consideration of land use activities.
