We consider the necessary redistribution of bicycles in public bicycle sharing systems in order to avoid rental stations to run empty or entirely full. For this purpose we propose a general Variable Neighborhood Search (VNS) with an embedded Variable Neighborhood Descent (VND) that exploits a series of neighborhood structures. While this metaheuristic generates candidate routes for vehicles to ...

This paper analyzes a bike-sharing service from both network efficiency and demand profiles perspectives. Specifically, it focuses on the BIZI in city of Zaragoza (Spain), which was launched May 2008 with aim increasing use bicycle city. Since then, number users has increased smoothly, currently constitutes an integrated transport mode as alternative to cars public The evolution service, using ...

In this paper, a Fuzzy Inference System (FIS) is fabricated on a riderless bicycle. The Fuzzy Inference System is based on a rule base inherited from human experience of bicycle riding. The steady turning motion and roll-angle tracking controls for the riderless bicycle were achieved by using fuzzy concept. Collection of sensors, actuator, micro-controller and electrical circuits were employed ...

There is growing recognition of the potential for cycling to provide more sustainable and active urban mobility. In Portugal, National Strategy Active Mobility aims at increasing bicycle modal share from current level below 1% 10% by 2030. This paper describes a planning practice method assess design network in Ponte de Lima, small starter Portuguese city, which only has some disconnected cycle...

OBJECTIVE To model the impacts of the bicycle sharing system in London on the health of its users. DESIGN Health impact modelling and evaluation, using a stochastic simulation model. SETTING Central and inner London, England. DATA SOURCES Total population operational registration and usage data for the London cycle hire scheme (collected April 2011-March 2012), surveys of cycle hire users...
