This article contains a literature review; the development process of the assessment framework as well as it discusses the results and challenges. This article summarizes the already existing Public Bike Sharing Systems and introduces a thorough categorization and a comparison methodology.

Importance of the topic According to the UN forecast (United Nations, 2013), the present world population of about 7.2 billion people by 2025 will reach 8.1 billion people, while in 2050, 9.6 billion. The largest increase is expected in the developing regions, while in developed ones, the population is barely growing. Along with this urbanization is expected to increase, which means that the number of urban inhabitants is expected to rise from 3.3 to 6.4 billion.

  • Bike-Sharing
    Bike-sharing Bike-sharing: History, Impacts, Models of Provision, and Future Paul DeMaio MetroBike, LLC Abstract This paper discusses the history of bike-sharing from the early 1st generation program to present day 3rd generation programs. Included are a detailed examination of models of provision, with benefits and detriments of each, and a description of capital and operating costs. The paper concludes with a look into the future through discus- sion about what a 4th generation bike-sharing program could be. Introduction Bike-sharing, or public bicycle programs, have received increasing attention in recent years with initiatives to increase cycle usage, improve the first mile/last mile connection to other modes of transit, and lessen the environmental impacts of our transport activities. Originally a concept from the revolutionary 1960s, bike-sharing’s growth had been slow until the development of better methods of tracking bikes with improved technology. This development gave birth to the rapid expansion of bike-sharing programs throughout Europe and now most other continents during this decade. Since the publication of “Will Smart Bikes Succeed as Public Transportation in the United States?” (DeMaio 2004), much has happened in the nascent field of bike-sharing. While the previous paper discussed the conditions for a success- ful program, this paper discusses the history of bike-sharing, provides a detailed 41 Journal of Public Transportation, Vol. 12, No. 4, 2009 examination of models of provision with benefits and detriments of each, exam- ines capital and operating expenses, and concludes with a look into the future of bike-sharing through a discussion about what a 4th generation bike-sharing program could be.

In some regions, the implementation of large-scale bike-sharing systems and improved cycling infra- structure are two of the factors enabling this growth. An increase in non-motorized modes of transportation makes our cities more human, decreases pollution, traffic, and improves quality of life. In many cities around the world, urban planners and policymakers are looking at cycling as a sustainable way of improving urban mobility. Although bike-sharing systems generate abundant data about their users’ travel habits, most cities still rely on traditional tools and methods for planning and policy-making. Recent technological advances enable the collection and analysis of large amounts of data about urban mobility, which can serve as a solid basis for evidence-based policy-making. In this paper, we introduce a novel analytical method that can be used to process millions of bike-sharing trips and analyze bike- sharing mobility, abstracting relevant mobility flows across specific urban areas.
