Review on theoretical assessments and practical implementations of ride-pooling
(2022)Digitized on-demand ride-pooling services emerged world-wide in recent years. They promise to provide a comfortable mobility alternative that is more efficient than conventional private transportation. While such services have already existed for decades in non-digitized form in emerging countries, digitized ride-pooling service were recently introduced in many cities to complement the existing public transport system. At the same time, ...Conference Paper -
Socially motivated travel and regular destination choice survey pre-test
(2022)For transportation modelers understanding and predicting spatial behavior has been a challenging task. There have been different approaches to explain what factors influence the decision to go to specific locations and at what times of the day; new methodologies are still under development in the literature. The two main tools used to collect data on mobility patterns and decisions are GPS and Survey methods; the first method gives detailed ...Conference Paper -
Modeling home office preferences and the implications for transport demand
(2022)This paper presents the research plan to elicit home office preferences during the current crisis and beyond as well as resulting transport demand and policy implications. We first identify gaps in the current literature on modeling and understanding work from home (WFH) and discuss in how far our proposal corrects for these limitations. We then introduce the survey instrument consisting of three waves collecting socioeconomic variables, ...Conference Paper -
Cycling potentials in Switzerland
(2022)The present work’s contribution lies in showing the importance of individual physical capabilities for cycling in Switzerland, as well as introducing a routing-tool that allows the application of these capabilities to estimate individualized cycling potentials. The regression of a binary model on daily cycling was estimated, using data from the Swiss Health Survey. It is found that the frequency of exercise explains the most variability ...Conference Paper -
Mode choice and ride-pooling simulation
(2022)Procedia Computer ScienceOn-demand ride-pooling systems have gained a lot of attraction in the past years as they promise to reduce traffic and vehicle fleets compared to private vehicles. Transport simulations show that automation of vehicles and resulting fare reductions enable large-scale ride-pooling systems to have a high potential to drastically change urban transportation. For a realistic simulation of the new transport mode it is essential to model the ...Conference Paper -
Spatiotemporal determinants of ride-pooling usage in the course of COVID-19 on the example of MOIA
(2021)The mobility provider MOIA operates Europe’s largest contiguous ride-pooling service in Hamburg, representing a testbed of how shared and digitized transport can help foster the transformation of urban mobility. To determine demand characteristics of ride-pooling through space and time and thus understanding usage and travel patterns, we use statistical analyses and spatial regressions. MOIA trip data from three different time periods are ...Conference Paper -
Descriptive route choice analysis of cyclists in Zurich
(2021)This paper presents (preliminary) results of a descriptive route choice analysis of cyclists in Zurich. Raw GPS trajectories from the MOBIS-COVID dataset are matched to an enriched OSM network. Two different map-matching algorithms are evaluated based on their sensitivity to hyper-parameters as well as different network configurations. The results of this paper lay the ground work for future modelling of the data using discrete route ...Conference Paper -
Mode choice, substitution patterns and environmental impacts of shared and personal micro-mobility
(2021)Shared micro-mobility services are rapidly expanding yet little is known about travel behaviour. Understanding mode choice, in particular, is quintessential for incorporating micro-mobility into transport simulations in order to enable effective transport planning. We contribute by collecting a large dataset with matching GPS tracks, booking data and survey data for more than 500 travellers, and by estimating a first choice model between ...Conference Paper -
Modelling shared e-scooters
(2021)Shared e-scooters have appeared quickly and in large quantities, yet little is known about their use. In this study, we explore spatial drivers of demand for shared e-scooter trips in Louisville (KY). We estimate a generalized linear mixed model with conditionally autoregressive random effects using 15 months of booking data, points of interests from Open Street Maps and US census data. We find that population density, the presence of ...Conference Paper -
Ride-pooling efficiency in large, medium-sized and small towns
(2021)Procedia Computer ScienceThis study introduces an autonomous ride-pooling service to six communities with varying population sizes and trip densities in the Munich Metropolitan Region. We analyze a) a laissez-faire scenario without additional policies, defining the modal shift through an incremental mode choice model and b) a draconian scenario in which each within-city car trip is replaced by ride-pooling. Results indicate a logarithmic increase in system ...Conference Paper
