Cluster Analysis of Public Bike Sharing Systems for Categorization

Abstract

<jats:p>The world population will reach 9.8 billion by 2050, with increased urbanization. Cycling is one of the fastest developing sustainable transport solutions. With the spread of public bike sharing (PBS) systems, it is very important to understand the differences between systems. This article focuses on the clustering of different bike sharing systems around the world. The lack of a comprehensive database about PBS systems in the world does not allow comparing or evaluating them. Therefore, the first step was to gather data about existing systems. The existing systems could be categorized by grouping criterions, and then typical models can be defined. Our assumption was that 90% of the systems could be classified into four clusters. We used clustering techniques and statistical analysis to create these clusters. However, our estimation proved to be too optimistic, therefore, we only used four distinct clusters (public, private, mixed, other) and the results were acceptable. The analysis of the different clusters and the identification of their common features is the next step of this line of research; however, some general characteristics of the proposed clusters are described. The result is a general method that could identify the type of a PBS system.</jats:p>

The Influence of Public Transportation Stops on Bike-Sharing Destination Trips: Spatial Analysis of Budapest City

“…There are 31 Park-and-Ride locations throughout the city's outskirts and nearby municipalities [45]. There are eleven bike-sharing operators in the city [46], conducting more than two thousand trips per day [47].…”

How Do Land Use, Built Environment and Transportation Facilities Affect Bike-Sharing Trip Destinations?

“…Cycling's share has risen in recent years, reaching 23% in 2015 [37]. The city promotes intermodal mobility options, with more than ten bike-sharing companies [38] conducting over two thousand trips per day [39].…”

Benchmarking bike-sharing systems: an analysis of the sustainable potential of use-oriented solutions

“…Existing research comparing bike-sharing systems across multiple locations worldwide has investigated various aspects but has not focused on comparing the sustainability potential of such solutions (e.g. Mátrai and Tóth, 2020). Research comparing the sustainability potential of solutions in different contexts is also necessary to understand their broad applicability and sustainable potential across different contexts (Boehm and Thomas, 2013).…”
