In this study a unique bicycle sharing program (BSP) is studied: BSP initiated by an urban transit provider (buses and trams). The idea that the combined use of BSPs buses trams could increase catchment area alone, therefore offering more competitive alternative for car. However, in scientific literature hardly any knowledge available regarding to what extent, whom how – combination used. This ...

Passenger information aims at improving the user-friendliness of public transport systems while influencing passenger route choices to satisfy transit user’s travel requirements. The integration of transit information from multiple agencies is a major challenge in implementation of multi-modal passenger information systems. The problem of information sharing is further compounded by the multi-l...

This paper aims to provide insight on whether bicycling for everyday travel can help US adults meet the recommended levels of physical activity and what role public infrastructure may play in encouraging this activity. The study collected data on bicycling behavior from 166 regular cyclists in the Portland, Oregon metropolitan area using global positioning system (GPS) devices. Sixty percent of...

Photosynthetic biohybrid systems (PBSs) combine the strengths of inorganic materials and biological catalysts by exploiting semiconductor broadband light absorption to capture solar energy and subsequently transform it into valuable CO2-derived chemicals by taking advantage of the metabolic pathways in living organisms. In this work, we first traverse through a brief history of recent PBSs, dem...

This paper develops a new approach to the modeling and analysis of device-to-device (D2D) underlaying multi-tier cellular network for dense hotspot communications, which consists macro base stations (MBSs), pico BSs (PBSs), femto (FBSs). A typicl user equipment (UE) can work either in D2D mode or mode. Considering this employs Poisson point process (PPP) model locations MBSs PBSs, uses cluster ...

Dockless bicycle-sharing (DLBS) is one of the novel transportation modes emerging in recent years. As a newly arisen mode, dockless inevitably has influence on existing components public system, especially metro system. A large number scholars have explored integration relationship between two. However, through evaluation and quantification data automatic fare collection data, we find that two ...

In shared bike-and-ride transit systems, commuters use shared bicycles for last-mile transport between transit stations and home, and between transit stations and work locations. This requires pools of bicycles to be located near each transit stop where commuters can drop off and pick up shared bikes. We study the optimal sizing of such bicycle pools. While various problems related to vehicle p...

Nonlinear polarization evolution based on beam splitter (PBS) is a classical technique for passive mode-locking of fiber lasers. Different from commonly used bulky PBS, in this paper all-fiber PBSs composed two parallel coupled microfibers have been proposed and fabricated under the condition appropriate microfiber diameter coupling length. Using our PBSs, passively mode-locked lasers also demo...
