TEEvil: Identity Lease via Trusted Execution Environments
(2019)arXivWe investigate identity lease, a new type of service in which users lease their identities to third parties by providing them with full or restricted access to their online accounts or credentials. We discuss how identity lease could be abused to subvert the digital society, facilitating the spread of fake news and subverting electronic voting by enabling the sale of votes. We show that the emergence of Trusted Execution Environments and ...Working Paper -

Impact of bicycle traffic on the macroscopic fundamental diagram
(2019)Arbeitsberichte Verkehrs- und RaumplanungInteractions between bicycles and cars have begun to attract increasing attention. This paper aims to investigate network-level car-bicycle interactions by quantifying the impact of bicycle traffic on empirical macroscopic fundamental diagrams (MFDs). First, the stratified re-sampling method is used to analyze the impact of bicycle-related facilities on network capacity and critical density. Then, the trapezoidal MFD function is applied ...Working Paper -
Fleet sizing for pooled automated vehicle fleets
(2019)Arbeitsberichte Verkehrs- und RaumplanungThis paper proposes an automated on-demand public transport service using different vehicle capacities to serve current car demand in cities. The service relies on space and time aggregation of passengers that have similar origins and destinations. It provides a point-to-point service with pre-defined pick-up and drop-off locations In this way, detours in order to pick-up en-route passengers is avoided. The optimization problem that ...Working Paper -
Privacy-by-design generative models of urban mobility
(2019)Arbeitsberichte Verkehrs- und RaumplanungNew streams of Location-based Services (LBS) Big data have risen society’s concerns in regards to data privacy. Even though these type of data sets are anonymised and aggregated in space and time, the risk of a privacy breach by user’s re-identification is still imminent. Still, LBS data has the potential to improve current travel demand models and transportation applications. We this in mind, we introduce a Privacy by Design framework ...Working Paper -
Theoretical and Methodological Framework for Measuring the Robustness of Social Institutions in Education and Training
(2019)KOF Working PapersSocial institutions are relatively stable patterns of behavior or joint action that help overcome fundamental problems and perform a function in society. The robustness of such institutions underlies their effectiveness at solving problems, but such robustness is difficult to assess. Building on different institutionalism approaches, this paper first develops a theoretical framework of social institutions. This framework combines Miller’s ...Working Paper -
Meeting in the middle: TVET programs’ education-employment linkage in developing contexts
(2019)KOF Working PapersTechnical and vocational education and training (TVET) programs are most successful at supporting youth labor markets when they combine education and employment. Education-employment linkage theory describes this combination in terms of power-sharing between actors from the education system and their counterparts in the employment system over key processes in the curriculum value chain of curriculum design, curriculum application (program ...Working Paper -

Using virtual reality to study bicycle level of service for urban street segments
(2019)Arbeitsberichte Verkehrs- und RaumplanungSince speed and passing distance of adjacent motorized traffic affect bicyclists' perceived safety and comfort, this research investigates the perception of speed and perception of space in virtual reality (VR) by varying vehicle speeds and lane widths in immersive virtual reality. Virtual reality has clear advantages over imagery and video surveys: it allows for a great control over virtual environments of existing and non- existing ...Working Paper -
Understanding travel and mode choice with emerging modes
(2019)Arbeitsberichte Verkehrs- und RaumplanungResearch presented in this paper analyses revealed preference data, obtained with a new travel diary and mode choice survey. This survey, called mobility Jakarta, combines both revealed and stated preference part and was conducted in the Greater Jakarta region. This is the first survey in Greater Jakarta that collected responses from a substantial sample of the population across the whole metropolitan area. Detailed analysis of the first ...Working Paper -

Expanding a (electric) bicycle-sharing system to a new city: Prediction of demand with spatial regression and random forests
(2019)Arbeitsberichte Verkehrs- und RaumplanungThe number of bicycle-sharing systems has undergone strong growth in the last two decades. This growth is part of a worldwide trend that has began in the 1990s and has strongly accelerated after 2005. Early bicycle-sharing systems have mainly been provided as a public service by cities, but meanwhile major international bicycle-sharing companies have emerged that seek to expand their operations to new cities. Two major strategic questions ...Working Paper -
How much of which mode? Using revealed preference data to design MaaS plans
(2019)Arbeitsberichte Verkehrs- und RaumplanungMobility as a Service (MaaS) seeks to integrate emerging shared mobility modes with existing public transportation (PT). Decisive to its uptake will be attractive subscription plans that cater for heterogeneous mobility needs. Research on willingness to pay for such plans has commenced, yet remains divided on a central question: how much to include of which mode, and how? Complementing previous research building on stated preference data, ...Working Paper -
Comparison of short-term traffic demand prediction methods for transport services
(2019)Arbeitsberichte Verkehrs- und RaumplanungThe purpose of this paper is to compare the short-term traffic demand prediction methods for transport services. Forecasting traffic demand throughout a city can help to organize the vehicles and minimize the waiting time for passengers and drivers. In addition, the prediction result is an important resource of other studies such as dispatching systems and recommendation systems. Therefore, short-term demand prediction is significant. ...Working Paper -
Valuable experience: How internships affect university graduates’ income
(2019)KOF Working PapersThis paper analyzes whether and how attending an internship during tertiary education affects income. We address endogeneity with an IV approach that exploits information regarding whether the internship was a mandatory component of the study. We further address selection into programs with mandatory internship by using the share of mandatory internships at the closest university, exploiting the low mobility of Swiss students. The results ...Working Paper -
A general framework for multi-modal macroscopic fundamental diagrams (MFD)
(2019)Arbeitsberichte Verkehrs- und RaumplanungCar traffic streams in urban networks are rarely homogeneous and usually contain some disturbances by other transport modes of different physical characteristics, e.g. bicycles or buses. Inevitably, these interactions decrease the network’s capacity and performance, but, so far, no methodology exists to assess the local interaction effects on the network level as for instance described in the macroscopic fundamental diagram (MFD). This ...Working Paper -
The prospects of on-demand urban air mobility in Zurich, Switzerland
(2019)Arbeitsberichte Verkehrs- und RaumplanungUrban Air Mobility (UAM) is a novel concept based on the use of Vertical Takeoff and Landing vehicles for aerial transportation of people in urban settings. It can, potentially, disrupt the way people move today. The factors and impact of demand drivers for UAM, are, however, largely unknown. Therefore, the goal of this study is to present a methodology to investigate demand for UAM using an agent-based approach. The methodology presented ...Working Paper -

The geocoded data are further allocated to the corresponding countries, regions and cities. When the address information was missing in the original patent document, we imputed it by using information from subsequent filings in the patent family. The resulting database can be used to study ...Working Paper -
Subsidized ridesourcing for the first/last mile: How valuable for whom?
(2019)Arbeitsberichte Verkehrs- und RaumplanungMany transit agencies partner with ridesourcing companies to offer subsidized first/last mile services. Ridership, however, has been low in many cases. Complementing popular operational explanations for low ridership, we explore two conceptual ones: using ridesourcing for the first/last mile adds an additional transfer and costs to the overall transit trip. We quantify both hypotheses simulating commuting trips in three structurally ...Working Paper
