Postestimation functions for R package mixl
(2022)Arbeitsberichte Verkehrs- und RaumplanungThis paper describes the (post)estimation framework and folder structure to ensure an efficient workflow when using the R package mixl. By running the postestimation script, several useful choice model indicators, such as elasticities, prediction accuracy, marginal effects and confusion matrices, are automatically calculated and saved as data sheets within the proposed folder structure.Working Paper -
The Housing Situation in Paris
(2021)As part of a research project, the Spatial Development and Urban Policy Research group collected data on the housing situation in six metropolises (Berlin, Chicago, London, Los Angeles, New York and Paris). This data brief provides an overview of the housing situation in Paris. It provides a general overview of the data and highlights some of the most interesting findings.Report -
Flow-inflated selective sampling
(2022)Arbeitsberichte Verkehrs- und RaumplanungAgent-based simulations have become a popular and powerful tool for simulating emergent mobil- ity modes. Often times, the memory and computing requirements are daunting. Scaling down agent populations by simulating only a fraction of all agents is a frequently used option to reduce these burdens. However, recent studies have pointed out the difficulty of scaling ride-sharing simulations as these rely heavily on demand density and do not ...Working Paper -
Grundlagen zur Festlegung des massgebenden Verkehrs
(2021)Der Festlegung des massgebenden Verkehrs kommt in der Verkehrsplanung eine grosse Bedeutung zu. Die Höhe des massgebenden Verkehrs hat einen entscheidenden Einfluss auf die Dimensionierung und Gestaltung der Verkehrsanlage und infolgedessen auch auf das zukünftige Verkehrsgeschehen, das sich im Betrieb der Anlage einstellen wird. Bisher wird Planenden mit der Norm VSS 40 016a eine Hilfestellung zur Ermittlung des massgebenden Verkehrs ...Report -
In-store or online grocery shopping before and during the COVID-19 pandemic
(2020)Arbeitsberichte Verkehrs- und RaumplanungThis paper presents results of a stated choice (SC) experiment to uncover the determinants of grocery shopping channel choice during this first wave of widespread COVID-19 infections where the most restrictive containment measures were in place, making the dataset unique. The choice sets were framed under regular and pandemic conditions, allowing the estimation of pandemic-specific effects for each of the choice attributes. Our results ...Working Paper -
A two-stage RP/SP survey to estimate the value of travel time in Switzerland
(2022)Arbeitsberichte Verkehrs- und RaumplanungStudies obtaining the value of travel time (VTT) typically have used data about short-term decisions such as mode/route choice. We present new results of long-term VTT using stated preference (SP) data on residential and workplace location choice and compare them with short-term (ST) values for the same respondents. In the long-term (LT) the VTT tend to be higher for car/motorbike (most pronounced for work trips by more than factor two) ...Working Paper -
Parking pricing vs. congestion pricing
(2020)SVT Working PapersAs traffic congestion gets worse year by year in metropolitan areas, cities search for solutions to improve their traffic performance and reduce their environmental impacts. This paper focuses on parking pricing and congestion pricing and their short-term effects not only on traffic congestion but also on the potential revenue for a city. We develop an easy to implement multimodal macroscopic traffic and parking search model for a central ...Working Paper -
Operator and user perspectives on fleet mix, parking strategy and drop-off bay size for autonomous transit on demand
(2018)Arbeitsberichte Verkehrs- und RaumplanungAutonomous vehicles (AVs), but in particular shared autonomous transit on demand (ATOD), promises many efficiencies in future transport provision, and may lead to concomitant changes in urban form. Considering the effects of car-oriented planning on the livability, efficiency and sustainability of 20th century cities, there is growing interest in how we may anticipate the changes that this disruption will bring about. Parking is one of ...Working Paper -
Population synthesis for microsimulation
(2010)Arbeitsberichte Verkehrs- und RaumplanungIn agent-based microsimulation models for land use (e.g., UrbanSim (2010)) or transportation planning (e.g., MATSim-T (2010)), agents’ decisions are simulated over time in order to predict future states of the system. The initial step is the definition of agents – usually, persons and households. If a snapshot of the entire population of the study area, taken at the simulation’s base year, were on hand, one could use this as an initial ...Working Paper -
