    Forecasting district-wide pedestrian volumes in multi-level networks in high-density mixed-use areas
    (Western Norway University of Applied Sciences (HVL), 06/2022) Mavros, Panos; van Eggermond, Michael; Erath, Alexander; Helle, Veera; Acebillo, Pablo; Xu, Shuchen; van Nees, Akkelies; de Koning, Remco Elric; Jacobsen Åsli, Thale [in: 13th International Space Syntax Symposium]
    This paper is concerned with improvements in the forecasting of pedestrian flows in multilevel pedestrian networks in high-density urban environments. 3D network topology measures are combined with land-use data, and validated against extensive pedestrian counts, to provide both evidence for the applicability of network analysis in tropical metropolises, as well as a calibrated tool for urban planners. The research focuses on four area in Singapore. These areas have in common that they all are prominent transport hubs, but differ in surrounding land-use types and dominant network topology (e.g. indoor, outdoor, above ground, below ground, at grade). Multi-level pedestrian networks were drawn based on OpenStreetMap, include sidewalks on both sides of major roads for a radius up to 2 kilometres from the site centroids. Spatial network analysis was performed using sDNA which allows vertical networks to generate measures describing the spatial configuration of the network. Subsequently, pedestrian counts were conducted during three consecutive days. In total, counts were conducted at more than 250 locations in 2018 and 2019, well before the global COVID19 pandemic. Pedestrian flows are set against a series of variables, including pedestrian attractors and generators (e.g. shops, offices, hotels, dwellings), and variables describing the spatial configuration of the network, using advanced regression models. Our results show that betweenness metrics (i.e. space syntax choice) combined with land-use yield high predictive power. Dependent on the study site, network metrics based on angular distance outperform those based on metric distance or perceived link distance. This research demonstrates that is necessary to account for the multi-level nature of networks, and that indoor flows through private developments cannot be neglected, in particular when planning for integrated transport developments. The paper concludes with recommendations and implications for practice.

    Pool More, Drive Less: An In-Depth Qualitative Investigation of Barriers and Motivators of Ride-Pooling in Autonomous Vehicles
    (2022) Stefanelli, Annalisa; Haiderer, Nicole; Studer, Nora; Schaffner, Dorothea; Erath, Alexander; van Eggermond, Michael
    Ride-pooling (RP) in autonomous vehicles (AVs) has the potential to combine the sustainability of public transport with the comfort of a private car. In our study we investigated consumers’ acceptance of RP in AVs through in-depth qualitative interviews, identifying relevant barriers and motivators of using this new mobility service.

    Aktivitätenbasierte Verkehrsmodelle: Methoden, Anwendungen, Vor- und Nachteile
    (Schweizerischer Verband der Strassen- und Verkehrsfachleute, 2022) Erath, Alexander; Vitins, Basil; Fellendorf, Martin; Arendt, Michael [in: Strasse und Verkehr]
    Aktivitätenbasierte Verkehrsmodelle (ABM) sind ein vielversprechender Ansatz der Verkehrsmodellierung. Gegenüber den in der Praxis mehrheitlich eingesetzten aggregierten Modellansätzen bieten ABM verschiedene Vorteile. ABM erlauben vielseitigere Auswertungsmöglichkeiten und flexiblere, methodisch konsistentere Abbildungen von intermodalen Wegeketten – zum Beispiel für ÖV- oder Langsamverkehrsstudien – und zeitlich dynamischen Massnahmen, zum Beispiel Mobility Pricing. Gleichzeitig sind ABM in der Praxis bisher noch weniger etabliert und stellen höhere Anforderungen bei der Modellierung. Im Rahmen eines SVI-Forschungsprojekts wurden Voraussetzungen sowie Vor- und Nachteile des Einsatzes von ABM untersucht, um Modellbetreibern eine Entscheidungshilfe zu bieten.
