Developing a passive GPS tracking system to study long-term travel behavior
(2018)Arbeitsberichte Verkehrs- und RaumplanungThis paper describes development and testing of a passive GPS tracking smartphone application and corresponding data analysis methodology designed to increase the quality of travel behavior information collected in long-term travel surveys. The new approach is intended to replace the pencil-and-paper travel diaries and prompted recall methods that require more user involvement due to requirements for manual data entry and/or high battery ...Working Paper -
The social aspect of residential location choice
(2018)Arbeitsberichte Verkehrs- und RaumplanungCommuting has been found to be one of the least enjoyable activities. As it is a consequence of the choice of home and work location, the question arises as to how its disutility is compensated. Urban location theory suggests a compensation in the housing or the labor market. While this provides part of the explanation, individuals’ personal networks may provide additional insights. Data from a social network survey were used to investigate ...Working Paper -
Modelling intermodal travel in Switzerland
(2018)Arbeitsberichte Verkehrs- und RaumplanungWe use data from the Swiss national household travel survey to 1. analyse the socioeconomic determinants for intermodal travel in Switzerland and 2. estimate a first large-scale multimodal recursive logit route choice model for urban trip making. We show that intermodal travel is mostly associated with ownership of transit subscriptions, which allow free at the point-of-use public transportation. We also present a framework using open-source ...Working Paper -
Comparing values of travel time obtained from residential, workplace and short-term decisions
(2018)Arbeitsberichte Verkehrs- und RaumplanungThe value of travel time (VTT) is an important element cost-benefit analysis of transportation projects, by encapsulating the willingness to pay of the population for improvements in the transport system. Those values are typically obtained from mobility behaviour data, in form of revealed or stated preference survey data. Although short-term decisions are typically used for this purpose, a growing number of authors is arguing that long-term ...Working Paper -
The German value of time (VOT) and value of reliability (VOR) study
(2018)Arbeitsberichte Verkehrs- und RaumplanungIn 2012 Germany’s Federal Ministry of Transport and Digital Infrastructure (BMVI) initiated several projects in preparation of the new Federal Transport Investment Plan (BVWP) 2030. This included an update of the general methodology and in particular of its cost-benefit analysis (CBA) which is used to evaluate the effects of hundreds of German infrastructure projects under study. As part of the work the first official values of time (VOT) ...Working Paper -
Studying cyclists’ behavior in a non-naturalistic experiment utilizing cycling simulator with immersive virtual reality
(2018)Arbeitsberichte Verkehrs- und RaumplanungThis study investigates the combination immersive virtual reality (VR) and an instrumented cycling simulator for in-depth behavioral studies of cyclists. To this end, a cycling simulator was developed, virtual environments resembling Singapore were created, combined with the output of a traffic microsimulation. This set-up was created with the specific objective of evaluating the effects environment properties and road infrastructure ...Working Paper -
How much parking space can carsharing save?
(2018)Arbeitsberichte Verkehrs- und RaumplanungProviding minimum parking requirements for new developments is an important part of urban design, taking away valuable space from people in the process and giving it to cars which are used for only small portions of the day. Free-floating carsharing is a service that provides fast point-to-point connections with an increased flexibility over more traditional carsharing services, with the promise of positive impacts on the environment, ...Working Paper -
Assessing the welfare impacts of shared mobility and Mobility as a Service (MaaS)
(2018)Arbeitsberichte Verkehrs- und RaumplanungMobility as a Service (MaaS) aims to allow less biased mode choice decisions by overcoming market segmentation. To this end, all available modes are offered at their respective marginal cost for each trip. Such a setting favors shared modes, where fixed costs can be apportioned among a large number of users. In turn, car-sharing, bike-sharing or ride- hailing may themselves become an efficient alternative of public transport. Although ...Working Paper -
Transportation service bundling – for whose benefit?
(2018)Arbeitsberichte Verkehrs- und RaumplanungNovel approaches to service bundling in the passenger transportation market are enabled by technology driven innovations and give rise to so called “Mobility as a Service” (MaaS) concepts. These approaches promise to increase service quality of existing public transportation, decrease car ownership, reduce private vehicle miles and lower the environmental burden of the transportation system. However, the potential effects of service bundles ...Working Paper -
Electric bicycle-sharing: a new competitor in the urban transportation market?
(2018)Arbeitsberichte Verkehrs- und RaumplanungElectric bicycles (e-bikes) are a new addition to bicycle-sharing and may improve its competitiveness. E-bikes allow for higher speeds at a higher level of comfort than conventional bicycles and compared to traditional bicycle- sharing, e-bike-sharing is better positioned to complement or compete with existing public transportation, or to even challenge established taxi services. Until this point, there has been no empirical analysis of ...Working Paper
