Valnerina Bike Sharing: prospettive di trasformazione territoriale
2018
Il contributo proposto intende esporre il progetto Valnerina Bike Sharing, un servizio intercomunale di bike sharing elettrico a pedalata assistita finanziato all’interno del Programma di Sviluppo Rurale per l'Umbria 2014 – 2020, che s’inserisce in un territorio compreso tra la Cascata delle Marmore e la ex ferrovia Spoleto-Norcia. Con l’obiettivo primario di incrementare il turismo responsabile in territori a elevato valore naturalistico, l'intervento intende incentivare la mobilità ciclo-pedonale, sostenibile e accessibile, utilizzando in gran misura l’arteria sentieristica della rete regionale che si snoda lungo l’asse del fiume Nera contribuendo alla definizione di un sistema unitario i…
Design, implementation and experimental results of an inductive power transfer system for electric bicycle wireless charging
2020
The use of renewable energy and the transformation of transport mode are crucial items for achieving an efficient and clean electrical mobility that allow being competitive on the market. In this context the interface between the power system and the Electric Vehicles (EVs) assumes a strategic role. Specifically, wireless energy transmission, based on Inductive Power Transfer (IPT), is an attractive solution for EVs charging. Moreover, the use of electric bicycles or kick scooters as mode of urban transport is continuously growing because they are lightweight, sustainable, easily parking, flexible and efficient transport devices. Owing to its benefits, the wireless power transfer can be con…
From cars to bikes – the feasibility and effect of using e-bikes, longtail bikes and traditional bikes for transportation among parents of children a…
2017
Abstract Background The present study aims to increase bicycling and level of physical activity (PA), and thereby promote health in parents of toddlers, by giving access to different bicycle types. There is a need for greater understanding of e-bikes and their role in the transportation network, and further effects on PA levels and health. Moreover, longtail bikes could meet certain practical needs not fulfilled by e-bikes or traditional bikes, hence increased knowledge regarding their feasibility should be obtained. No previous studies have investigated whether providing an e-bike or a longtail bike over an extended period in a sample of parents of toddlers influence objectively assessed a…
Experimental characterization of a proton exchange membrane fuel-cell for hybrid electric pedal assisted cycles
2017
This paper presents a feasibility study on the prototyping of a hybrid EPAC (Electric Pedal Assisted Cycle) Through an FC-B-UC (Fuel Cell - Battery - Ultra-Capacitors) power system. Aim of this work is the characterization of a PEMFC (Proton Exchange Membrane Fuel Cell) in order to confirm its theoretical performances and to verify the possibility of its installation on an e-bike.
Efecto del diámetro de las ruedas (26 pulgadas vs 29 pulgadas), en la transmisión de las vibraciones y en el rendimiento, en bicicleta de montaña
2017
Desde 2010 ha habido una creciente implantación del uso de bicicletas de montaña de 29 pulgadas (29”) para pruebas de campo a través. Los estudios científicos que respalden las ventajas de este cambio, quizá el más importante en la historia del BTT, son muy escasos, con metodologías discutibles y con tamaño muestral escaso. El objetivo principal de esta tesis es medir el rendimiento de dos bicicletas de montaña equivalentes (una de 26 y otra de 29”) en la realización de un trabajo de campo tanto de pruebas analíticas de comportamientos aislados como en un circuito campo a través. Además del apartado de rendimiento, se realizará un análisis de la vibración que transmite la bicicleta al cicli…
An Immersive Motor Protocol for Frailty Rehabilitation
2019
Frailty is a pre-clinical condition that worsens physical health and quality of life. One of the most frequent symptoms of frailty is an increased risk of falling. In order to reduce this risk, we propose an innovative virtual reality motor rehabilitation program based on an immersive tool. All exercises will take place in the CAVE, a four-screen room with a stationary bike. The protocol will include two types of exercises for the improvement of balance: “Positive Bike” and “Avoid the Rocks.” We will choose evaluation scales related to the functional aspects and subjective perception of balance. Our aim is to prove that our innovative motor rehabilitation protocol is as effective as or more…
Understanding the Key Factors of Shared Mobility Services: Palermo as a Case Study
2020
The potential success of shared mobility services in the urban area strongly depends on careful tariff planning, adequate sizing of the fleet and efficient integrated public transport system, as well as on the application of policies in favor of sustainable modes of transport. The balance between earnings and expenses is not always an easy target for the companies in those cities where these services are not well-rooted in the citizens’ mobility habits. Often only large operators in the sector can continue to offer a service generating profit. However, several factors can determine the success or the failure of shared mobility services. The objective of this study is to identify, thanks to …
Performance of LoRa for Bike-Sharing Systems
2019
Today bike sharing systems are becoming popular in many cities as short-distance transit vehicles. More than 18 million bicycles are available worldwide for public use and one of the main problems that afflicts such sharing systems is the loss of bikes, which can be stolen or simply left in unknown locations. Thus, many bikes are docked or tracked using GPS and costly cellular connections. In this paper, we consider the emerging Long Range (LoRa) technology for use in bike sharing systems. LoRa exploits free ISM bands and has been conceived for low power and low data rate applications. Additionally, LoRa is characterized by large cells and heterogeneous application domains, which may lead t…
Optimization of urban delivery systems based on electric assisted cargo bikes with modular battery size, taking into account the service requirements…
2021
The implementation of new forms of urban mobility is a fundamental challenge for improving the performance of city logistic systems in terms of efficiency and sustainability. For such purposes, the exploitation of electric vehicles is currently being investigated as an alternative to traditional internal combustion engines. In particular, the employment of lightweight electric cargo bikes is seen as an attractive possibility for designing improved city distribution systems. Such vehicles, however, present substantial limitations related to their endurance, speed, power, and recharging times; therefore, their configuration must be optimized considering the actual operational context and the …
Un Modello di Massima Copertura della Domanda per l’Allocazione Ottima delle Ciclostazioni di AMAT
2018
AMAT Palermo S.p.A. is the public transport company of the municipality of Palermo. AMAT manages the bike sharing system and within a sustainable mobility project has involved the DSEAS and four secondary schools to the research project “GoToSchool”, a project whose main aim is to foster the use of the bike by the students in getting to the school.The project developed in two phases: the first phase was devoted to the estimate of the demand of bike sharing service from the students; the second phase was committed to the study of an optimal facility allocation problem in order to maximize the demand of bike sharing service arising from students.The optimization model can be easily customized…
