Tidskriftsartikel (refereegranskat)abstract
- Since bicycles and bike-sharing systems are becoming increasingly important in modern transportation contexts, we suggest in this paper an alternative method to incorporate cycling among the freight transport alternatives within urban areas. We propose pursuing a sustainable initiative of crowdsourced delivery where some of the urban good deliveries may be voluntarily undertaken by users of the free-floating bike-sharing systems while following their prefixed route in exchange for some kind of reward. We believe that a network design model that allows properly allocating the resources of the bike-shared mobility service could improve the potential of crowdshipping, making it a viable support and supplement for the local postal services, and more easily accepted and adopted in urban contexts. An application to a case study has been embodied to show the effectiveness and advantages of our proposal.

An urban bikeway network design model for inclusive and equitable transport policies
- 2019
-
Ingår i: Transportation Research Procedia. - : Elsevier BV. - 2352-1465. ; 37, s. 59-66
-
Tidskriftsartikel (refereegranskat)abstract
- This study suggests an optimization framework to plan and design a network of bike lanes in an urban context, based on equity principles and subject to a given available budget. The novelty of the proposal consists in an objective function that aims at minimizing the existing inequities among different population groups in terms of accessibility/opportunity to the bikeways. The proposed methodology represents a reliable decision support system tool that could help transport authorities/managers to select the priority areas of their future investments related to the cycling infrastructures. To prove the effectiveness and value of the methodology, an application with relevant analysis to a test case study is presented.

- Global society is rapidly ageing. Research on ageing and mobility suggests that better synergies could exist between older people and the built environment. The age-in-place policy will put increased demands on the transport system as a key facilitator for access. The main goal of this study is to examine the spatial distribution of older adults, assessing if it could be affected by selective characteristics of the surrounding built environment and, if so, to what extent. The study district is the region of Scania in the southern part of Sweden. Register-based longitudinal socio-demographic data such as income, employment and education associated with the outcomes of previous travel surveys conducted in the region are the main data sources to be considered. Correlated with population density patterns and expansion of the railway network, this longitudinal approach is expected to reveal causal inferences. Better knowledge may be gained about the environmental and demographic factors that may potentially lead older people to adapt their mobility choices according to the area in which they reside. Research findings could provide useful policy recommendations both to land use and transport planners, contributing to the development of age-friendly neighborhoods, cities and regions.

Tidskriftsartikel (refereegranskat)abstract
- The implementation of an appropriate pricing policy in an urbanarea could alleviate both environmental and congestion problemsby encouraging a shift towards more sustainable modes oftransportation. However, any positive net social welfare balancedelivered by the policy can hide unacceptable regressive effects.Therefore, it is crucial to investigate any change in relative levelsof accessibility among different categories of transport networkusers.This study focuses on the application of a cordon-basedcongestion pricing scheme on a multimodal network, whereprivate cars and public transportation coexist, and includes asensitivity analysis by varying the size of the charging area andthe amount of the toll, for a monocentric urban reality. Takinginto account an elastic demand associated with each proposedcharging scenario, the related distributional effects are exploredusing the Theil index, with a quantitative assessment of theinequalities in the accessibility variations across the users of thenetwork.

Inequalities in access to bike-and-ride opportunities : Findings for the city of Malmö
- 2019
-
Ingår i: Transportation Research Part A. - : Elsevier. - 0965-8564 .- 1879-2375. ; 130, s. 673-688

Tidskriftsartikel (refereegranskat)abstract
- Bike-and-ride – that is, integrating cycling and public transport in one trip – is an attractive combination, as cycling as an active and clean mode is faster than walking and more affordable and flexible than other alternative modes of transport. Using cycling as a feeder mode to public transport could potentially allow people to reach more opportunities and improve their mobility, and ultimately, their well-being. Therefore, it is relevant to investigate the inequalities in access to bike-and-ride options across population groups.In this context, we suggest assessing the inequalities in bicycle access to the main transport hubs of a city by developing a composite indicator based on accessibility measures and the Theil index of inequality. This indicator captures the role of both private and public bikes – part of a Bike Sharing System (BSS) – in accessing the existing public transport system. The novelty of our approach lies in bringing the distributional justice perspective in the accessibility evaluation of transport and analysing the inequalities within and between any arbitrarily defined population groups. Moreover, in addition to travel time by bike, this accessibility measure incorporates a series of bike-related features, such as the typology of bike lanes (separated from or shared with roads), the presence of a BSS in the network, and bike facilities (e.g., parking racks) in transport hubs.The proposed methodology is applied to a real case study of the city of Malmö, Sweden, to prove its efficacy and usefulness. In particular, we examine how the level of bicycle access to the major public transport destination (including train stations and regional bus hubs) varies across the population. While considering the contextual properties of the city of Malmö, the inequalities are analysed in relation to spatial dimension and social background of the population, it is possible to extend the proposed analysis by including further features of the population, such as income or gender, and apply the same approach to different contexts.

Railway network design and regional labour markets in Sweden
- 2019
-
Konferensbidrag (refereegranskat)abstract
- Investment in railways, and transport infrastructure in general, are often motivated because they are believed to improve peoples’ accessibility to jobs. By linking together and increasing the size of labour markets, the matching between individuals and jobs is improved, and the productivity increases. Communities and municipalities lobby for investments that lead to higher accessibility and those that are successful often see inflows of people as a consequence. This paper looks at the entire Swedish railway network, at the level of service of each station and at the connectivity among stations during the morning peak hour, considering different time bands. Causal inferences between job accessibility levels and socio-demographic features are explored and disclosed, looking at the longitudinal impacts of railway investments over 4 years (from 2011 to 2014) on annual wages. Estimating a fixed effects model, very small effects on wages have been found with the increase in the number of jobs around accessible rail stations. These preliminary results indicate that additional jobs along the rail network seem to have a marginal effect. The findings of this analysis, if communicated to planners, may assist them in assessing and predicting the effects of future railway measures to implement over the Swedish territory.

Bokkapitel (refereegranskat)abstract
- Bike-sharing systems are an emerging form of sharing-mobility in manycities worldwide. The travel patterns of users that take advantage of smart devices to ride a shared-bicycle in two large cities (Chicago and Budapest) have been investigated, with analysis of approximately two million transaction data records associated with bike trips made over a three-month period in each location. Several aspects of user travel behavior—such as day and time of travel, frequency of usage, duration of usage, seasonal and peak/off-peak variations, major origin/destinations—have been included in this analysis. The results show that in both cities the bike-sharing option is a male-dominated alternative, particularly welcomed by younger groups, with the largest share of trips occurring in the afternoon peak. Appropriate usage of opensource big-data provides important lessons for successful vehicle sharing models,allowing the application of the findings to other cities and mobility options wherethese systems are still developing.
