Existing urban transportation in Greater Jakarta
(2019)Arbeitsberichte Verkehrs- und RaumplanungAgent-based models have become popular over the years as more traditional modelling approaches were not suitable for studying emerging transportation modes and transport policies. However, creating a detailed scenario, which is the basis of the agent-based model that represents the supply and demand for a study area, is not trivial and requires substantial effort. This is even more the case when the study area is large and contains ...Working Paper -
Optimal pricing and investment in a multi-modal city
(2019)Arbeitsberichte Verkehrs- und RaumplanungThe three-dimensional macroscopic fundamental diagram (3D-MFD) is a physically consistent functional relationship between the accumulation of buses and cars and each modes average speed in an urban network that captures interactions among vehicles. The 3D-MFD network design problem (3D-MFD-NDP) builds upon advances in 3D-MFD estimation that explicitly link design variables of urban transportation networks to the shape of the 3D-MFD. This ...Working Paper -
Learning from the MaaS experience in Augsburg, Germany
(2019)Arbeitsberichte Verkehrs- und RaumplanungRecent technological advances have led to a surge of new shared transportation modes. This development has inspired the concept ‘Mobility as a Service’ (MaaS), which seeks to integrate the emerging shared modes with conventional public transportation. Enabled by this development, multimodal mobility plans (i.e., mobile phone plans for mobility) have become a topic of particular interest both for transportation scholars and practitioners ...Working Paper -
Will automated vehicles help to reduce congestion?
(2019)Arbeitsberichte Verkehrs- und RaumplanungAutomated vehicles are widely expected to bring about various benefits for (urban) transportation, e.g. by increasing road capacities and reducing generalized cost of travel. However, the latter may induce additional demand for road transportation, possibly counteracting gains in accessibility. Hence, the net impact of vehicle automation on road network performance is still unclear. This research uses the macroscopic fundamental diagram ...Working Paper -
Improved public transportation in rural areas with self-driving cars: The Example of Swiss Train Lines
(2019)Arbeitsberichte Verkehrs- und RaumplanungPublic transport lines, especially train lines, have historically played an important role as economic lifelines of rural areas. They are one of the most important factors contributing to economic prosperity as they provide access to mobility for all the inhabitants of these regions. Maintaining such rural public transport lines can be a challenge due to the low utilization inherent to rural areas. Today, with the emergence of fully ...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 -
Capturing network properties with a functional form for the multi-modal macroscopic fundamental diagram
(2019)Arbeitsberichte Verkehrs- und RaumplanungIn urban road networks, the interactions between different modes can clearly impact the overall travel production. Although those interactions can be quantified with the multi-modal macroscopic fundamental diagram; so far, no functional form exists for this diagram to explicitly capture operational and network properties. In this paper, we propose a methodology to generate such functional form, and we show its applicability to the specific ...Working Paper -
Subsidized ridesourcing for the first/last mile
(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 -
Begleitstudie SBB Green Class - Abschlussbericht
(2019)Arbeitsberichte Verkehrs- und RaumplanungMit der Green Class haben die SBB eines der weltweit ersten grossen Pilotprojekte zu einer multimodalen Mobilitäts-Flatrate durchgeführt. In einer wissenschaftlichen Begleitstudie untersuchen das IKG und das IVT der ETH Zürich die verkehrlichen und ökologischen Wirkungen dieses Angebots. Im ersten Teil des Berichts wurden dafür die Befragungs- und Bewegungsdaten der Teilnehmenden im Detail analysiert und mit Informationen aus dem Mikrozensus ...Working Paper -
Predicting response rates of all and recruited respondents
(2019)Arbeitsberichte Verkehrs- und RaumplanungThis paper reports on the link between a well-defined measure of response burden and response rates among all (uncommitted) and pre-recruited respondents. We show within the limits of our sample of 68 survey waves (including pre-tests; resulting from 35 studies) that the response burden impact is mediated by the level of the commitment of the respondents and the presence of a monetary incentive. This is the first time that a research group ...Working Paper
