How did bicycle share increase in Vitoria-Gasteiz?
No full text[EN] Cycling mobility has often been neglected in transport planning. Nevertheless, the potential benefits of increasing the bicycle share make cycling promotion a key element for transforming cities toward sustainability. This research addresses the case study of Vitoria-Gasteiz, a city where the bicycle share has almost quadrupled in eight years. Through an exploratory analysis of the city´s last mobility surveys we find some insights into the bicycle user profile and the cycling trip. The results show differences between cyclist and non-cyclist groups especially by gender and age. On this account, target groups for addressing probike transport policies can be better identified.DOI: http://dx.doi.org/10.4995/CIT2016.2016.4105http://ocs.editorial.upv.es/index.php/CIT/CIT2016Barberan, A.; Monzon, A.

Children as Therapeutic Orphans in Humanitarian Research
No full textAUTHOR AFFILIATION: Alana Monzon, The Ohio State University, USA, [email protected] research in children poses a variety of ethical concerns, and these concerns, further exacerbated in the context of a humanitarian crisis, may understate the need for research. It can be difficult to navigate what justifies research versus treatment in children, and therapeutic interventions may easily draw from existing knowledge of pediatric research outside a trauma context. In doing so, however, the unique needs of children following a large-scale disaster or trauma are overlooked, creating an evidence-based knowledge gap. This paper will evaluate ethical considerations in humanitarian crisis research, such as natural disaster, community crisis, and refugee resettlement, and show that research should be designed with an ethical consideration of not merely protecting vulnerability but rather enhancing the resilience of children in traumatic events. Furthermore, it will be argued that when research is not engaged in this way, a more problematic ethical concern arises similar to the ‘therapeutic orphan’ in clinical research. By failing to engage in research of children who experience traumatic events, not only do their health and social needs go unmet, but they also lose an opportunity to give voice to their own self-determination in the midst of distress and insecurity
ECO-ROUTING: MORE GREEN DRIVERS MEANS MORE BENEFITS?
No full text[EN] Information and Communications Technology (ICT)/Information and Technology Services
(ITS) can play an important role in the transport sector, helping in maintaining accessibility
and contemporarily optimizing the use of the vehicles. Among these ICT measures, ecorouting
seems a promising one. Drivers normally follow the route which minimizes their
generalized costs, normally time and money. But environmental concern is increasing, and
drivers are starting to think about the effects of their driving. This means including CO2
emissions or fuel consumption in their route choice. But is this always positive,
independently of the traffic situation and the penetration level of green drivers?
This articles aims to analyze what happens in terms of fuel consumption, CO2 emissions and
travel time, when different penetration levels of drivers, and with different traffic situations,
follow the route of minimum fuel consumption instead of the conventional generalized costs.
The analysis is based on a modelling process using a transport model of the whole region of
Madrid. A total of 18 scenarios are considered: 3 reference scenarios (for congested, medium
and low flow traffic situations), and 5 different penetration levels of green drivers for each
traffic situation.
Results show how impact varies substantially with the level of traffic and, also, that the more
the best is not always trueValdés Serrano, C.; Perez Prada, F.; Monzon De Caceres, A. (2016). ECO-ROUTING: MORE GREEN DRIVERS MEANS MORE BENEFITS?. Editorial Universitat Politècnica de València. 1261-1268. https://doi.org/10.4995/CIT2016.2015.3250OCS1261126
Identificación de corredores prioritarios de carreteras para la aplicación de estrategias de reducción de emisiones GEI. Caso de España
No full text[ES] Lograr un transporte bajo en carbono es crucial en la planificación y gestión del transporte
por carretera. Existen diversas acciones para la reducción de emisiones del transporte por
carretera: sobre la demanda, la tecnología del vehículo, la gestión del tráfico, etc. Pero, antes
de realizar cualquier actuación, es necesario identificar cuáles son los puntos de la red que
necesitan una acción prioritaria.
Este trabajo describe un índice para la identificación de tramos y corredores
prioritarios para hacer frente a los problemas de emisiones GEI. La herramienta HERA de
evaluación del consumo de energía y emisiones del tráfico, es utilizada para estimar los
parámetros del Índice Prioritario de Emisiones (IPE) y para evaluar diferentes estrategias de
gestión y diseño de carreteras. El IPE identifica la prioridad de acción en un tramo o corredor
en base a las emisiones totales del tráfico y a la alta intensidad de emisiones unitarias del
tramo, es decir, la ineficiencia.
La Red de Carreteras del Estado (2012) se toma como caso de estudio, y los
resultados se muestran en mapas ayudados por un SIG. Se identifican siete corredores
prioritarios, que representan el 25% de la red y contribuyen con el 52% de las emisiones GEI
totales de la red en 2012. Los corredores más ineficientes corresponden a aquellos con una
alta proporción de vehículos pesados, altas velocidades de vehículos ligeros y aquellos que
presentan pendientes pronunciadas. Sobre los corredores prioritarios han sido aplicadas una
serie de estrategias de reducción de emisiones. La estrategia más efectiva –aparte de la
integración de varias estrategias- es la reducción de la velocidad de los vehículos ligeros.
Una reducción de velocidad de -10km/h podría producir un 3,85% de ahorro anual de
emisiones sobre dichos corredores, llegando a ahorrar 566 KtCO2eq anuales.Sobrino Vázquez, N.; Monzon De Caceres, A. (2016).
