The social acceptance of airport expansion scenarios: A factorial survey experiment
2020
Abstract Against the background of growing aviation and protests against air traffic in many countries, we employ a factorial survey experiment to examine the social acceptance of airport expansion scenarios in two European cities located near the international airports of Frankfurt (Germany) and Zurich (Switzerland), respectively. In our experiment, respondents evaluated short descriptions of airport expansion scenarios that varied in several impact attributes. The experiment helps to disentangle to what extent environmental impacts (aircraft noise), economic impacts (job creation), participatory justice aspects (participation opportunities), and distributive justice aspects (noise distrib…
The impact of scrappage programmes on the demand for new vehicles: Evidence from Spain
2018
Abstract We evaluate the impact of the Spanish car scrappage programme introduced in May 2009 on short-run car purchases. The scrappage programme was simultaneously discussed and implemented and was therefore exogenous to the consumers. We analyse the effect of this programme on household new car purchase decision and household expenditures. The results show that the scrappage programme increased the probability of buying a new car but decreased the mean expenditure devoted to the purchase of this new vehicle. We also evaluate the effect of financial aid on household welfare. Our best estimate of the welfare gain related to the scrappage programme is very similar to the aid of €1000 offered…
Schedule-Based Integrated Intercity Bus Line Planning via Branch-and-Cut
2018
This work addresses integrated line planning for intercity bus lines, which differs in several respects from line planning in public transit. Passengers in intercity transportation decide on specific timetabled services to get to their destination. This is a contrast to an urban setting with higher frequencies, where it is generally sufficient to choose a line. Furthermore, intercity bus transportation in deregulated markets is usually characterized by fierce competition within and across modes. Customers are highly sensitive to price, time of day, duration, convenient access to stations, and service quality. Hence, bus line operators need to decide thoroughly on every single timetabled se…
A GIS-Based Methodology to Estimate the Potential Demand of an Integrated Transport System
2017
In the design of a new public transport system or of an extension of an existing system, the choice of a suitable placement of stations and stops in the territory and the definition of the main axes are very important. The different choice in the number and distribution of the stops of a road transport system or of a railway transport system, in fact, makes the system more or less widespread and affects the consistency of the catchment area and the attractiveness of the system. The accessibility of a system, add to the reliability in providing the service, is the fundamental parameter influencing the modal split of the users. Therefore, the Public Administration must have tools able to eval…
Investigation of the consequences of the modifiable areal unit problem in macroscopic traffic safety analysis: A case study accounting for scale and …
2019
Abstract Traffic safety analysis at the macroscopic level usually relies on previously defined areal traffic analysis zones (TAZs) that are used as the units of investigation. Hence, statistical inference is made on the basis of such units, implying that the consideration of a certain TAZ configuration may influence the results and conclusions achieved. Regarding this, the modifiable areal unit problem (MAUP) is a well-known issue in the field of spatial statistics, which refers to the effects that arise in statistical properties and estimations when there is a change in areal units of analysis. In this paper, the consequences of MAUP have been investigated through a dataset of traffic cras…
Transport engineering and reduction in crime: the Medellín case
2016
This study analyses the impact of the aerial cable car public transport system, locally known as Metrocable, in Medellín (Colombia), on the reduction in crime. As part of the municipal policies of social urbanism, Metrocable has contributed to the social integration of the population in the outlying neighbourhoods, which has increased safety in Medellín. This case is clearly of great interest from the point of view of Criminal Sciences, demonstrating how crime can be combated by using tools beyond ius puniendi.

Investigating Mobility Gaps in University Campuses
2018
The objective of the present research is to carry out a gap analysis between current mobility situations and the needs, future plans and priorities regarding a number of thematic areas on the issue of mobility in university campuses. For this purpose, an interview was conducted involving 36 experts from seven Southern European Universities. More specifically, experts from each university were asked to analyse and rate both the current and the desired situation in the campus under their responsibility with focus on the following thematic areas: parking management, soft modes infrastructure, public transport, car related issues, road infrastructure, environment and energy, mobility management…
Socio-demographic, personal, environmental and behavioral correlates of different modes of transportation to work among Norwegian parents
2016
Abstract Background Cycling and brisk-walking to work represents an opportunity to incorporate sustainable transport related moderate- to- vigorous physical activity (MVPA) into daily routine among adults, and thus, may make an important contributing to health. Despite the fact that walking and cycling is an option for many commuters and also brings a number of benefits, a considerable proportion of commuters choose to use other means of transport when cycling and walking would be a highly appropriate transport mode. The object of this study was to assess the associations between modes of commuting to the workplace among parental adults; taking socio-demographic, personal, environmental and…
Peers oder Punkte
2016
Der Beitrag nimmt eine Verschrankung zweier relevanter Untersuchungsfelder der Unterrichtsforschung, Leistungskonstruktion und Peer Group, vor mit dem Ziel, die Auswirkungen schulischer Leistungsanforderungen auf das soziale Beziehungsgefuge der Schulklasse zu identifizieren. Die Daten stammen aus einem laufenden ethnografischen Forschungsprojekt zum Thema Leistungskonstruktionen in unterrichtlichen Hausaufgabensituationen. Anhand eines Beobachtungsprotokolls werden die Interpretation und die Entwicklung erster Theoretisierungen als Auswertungsschritte der Grounded-Theory Methodologie exemplarisch dargestellt. Die Interpretation zeigt die spannungsreichen Auswirkungen von Leistungssituation…
Zahlungsbereitschaft für kollektive Umweltgüter / Willingness to Pay for Collective Environmental Goods
2007
Zusammenfassung Um kollektive (Umwelt-)Güter zu bewerten, verwenden Ökonomen seit nunmehr etlichen Jahren Auskünfte zur Zahlungsbereitschaft, die in Umfragen erhoben werden. Die Zahlungsbereitschaftsanalyse hat sich zu einem wichtigen Forschungsfeld entwickelt, dessen Ergebnisse zum Teil in politische und juristische Entscheidungen einfließen. Der vorliegende Artikel fordert die Soziologie auf, sich in dieses Forschungsfeld einzumischen. Konkret wird am Beispiel der monetären Bewertung biologischer Vielfalt im Wald gezeigt, dass die Soziologie mit ihrem Fundus an Handlungstheorien Erklärungsschwächen der herkömmlichen ökonomischen Theorie überwinden kann. Auf der Grundlage einer empirischen…
