Item type:Publication, Access status: with files , Do mobility hubs boost the adoption and impact of carsharing in the urban periphery? Insights from a mixed-methods case studyMobility hubs represent an emerging instrument in transportation planning, with the potential to catalyze the uptake and effects of carsharing. However, extant research on the interplay between mobility hubs and carsharing is limited and has focused predominantly on highly urbanized areas. The question of how mobility hubs and carsharing interact in the urban periphery, where conditions for carsharing are considerably less favorable, remains largely unexplored in the literature. In this context, our paper seeks to answer whether mobility hubs enhance the adoption and impact of carsharing on the outskirts of a major city. Utilizing newly established mobility hubs in southern Hamburg, Germany, as a case study, our analysis draws on 14 interviews with residents living near these hubs and a survey of the local population (n = 310). Our findings indicate that peripheral mobility hubs have a positive influence on the adoption of carsharing and the willingness of carsharing users to forgo car ownership. This phenomenon can be attributed to the heightened visibility of carsharing services and the enhanced accessibility of carsharing vehicles and parking spaces. However, the efficacy of the mobility hubs was hindered by multiple factors, including hub-related issues (e.g., parking spaces occupied by unauthorized vehicles) and systemic deficiencies in carsharing services in peripheral areas (e.g., insufficient vehicle availability or unattractive pricing for trips across the city limits). Consequently, while mobility hubs in the urban periphery demonstrate capability in fostering carsharing, their impact remains constrained in the absence of comprehensive measures to improve carsharing offerings in these areas.Publicationtype: Journal Article91 23 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , KoGoMo Phase II Schlussbericht. Stärkung der kommunalen Governance für die Umsetzung von neuen Mobilitätsangeboten in Kooperation mit privaten Anbietern(2025); ; The KoGoMo project aims to strengthen municipal governance capabilities in relation to private-sector sharing and mobility providers, and to foster cooperation in order to establish sustainable mobility services in urban areas. Within the framework of a real-world laboratory in the Hamburg district of Harburg, various new mobility products were successfully implemented. This includes the expansion of carsharing services in collaboration with Hochbahn, with 13 hvv switch mobility points established that also accommodate free-floating carsharing providers. In addition, pilot projects with the providers Cambio and Dorfstromer were initiated for station-based carsharing with a minimum revenue guarantee to ensure economic viability during the initial phase. Furthermore, a cargo bike rental service with hourly rentals was established in Harburg’s city center, with its user structure evaluated by TUHH. An on-demand service by hvv hop was also introduced, while simulations for a MOIA ridepooling service demonstrated that such a service is not feasible in the area. Close cooperation between the Harburg District Office, TUHH, and the Authority for Transport and Mobility Transition enabled structured and accelerated site planning and the gradual expansion of mobility services. The offerings developed within the project will be continued beyond the project duration and have received positive feedback from the population, although mobility behavior has not yet changed significantly. The insights gained are being incorporated into a governance strategy that is intended to serve as a guideline for other districts and municipalities to facilitate the introduction of sustainable mobility services and to transfer the project’s successes.Publicationtype: Research Report136 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Access status: with files , Neue Mobilitätsangebote als Teil der kommunalen Mobilitätslandschaft : Grundlagen für die kooperative Zusammenarbeit der Akteure ; 1. Werkstattbericht aus dem Projekt KoGoMo mit Ergebnissen der Projektphase I(2022); Das Spannungsfeld zwischen privaten Anbietern, kommunalen Zielen und einem aus der Perspektive von Nutzerinnen und Nutzern optimierten Mobilitätsangebot ist das Thema des BMBF-geförderten Forschungsprojektes „Stärkung der kommunalen Governance für die Umsetzung von neuen Mobilitätsangeboten in Kooperation mit privaten Anbietern“ (Projektakronym: KoGoMo). Das Projekt geht davon aus, dass Kommunen eine zentrale und aktive Rolle bei der sozial-ökologischen Gestaltung und Diffusion der privatwirtschaftlichen Angebote der Neuen Mobilität einnehmen können und sollen. Das zentrale Ziel des Projektes ist es daher, die kommunale Steuerungsfähigkeit gegenüber privatwirtschaftlichen Mobilitätsanbietern zu stärken sowie Kooperationen mit ihnen zu fördern, um leichter auf eine Mobilitätslandschaft hinwirken zu können, die den Nachhaltigkeitszielen entspricht.Publicationtype: Book845 1128 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Differenzierung der Feinstaubexposition in Deutschland nach sozioökonomischem Status : Sachverständigengutachten im Auftrag des UmweltbundesamtsAbstract: Differentiating exposure to particulate matter in Germany by socioeconomic status. Air pollution is a significant risk factor for human health. This study investigated the possibility for differentiating the population exposure to particulate matter by socio-economic status in Germany. A nationwide dataset on PM2.5 background concentrations at a resolution of 2 x 2 km² was used to quantify exposure. PM2.5 datasets for the cities of Hamburg (total concentrations at 100 x 100 m²) and Berlin (background concentrations at 500 x 500 m²) were used for additional local analyses. The annual net household income (at 1 x 1 km²) as well as housing rent and pur-chase price indices (at block level) were used as indicators for socio-economic status (SES). Data pre-processing included validation of housing block data, population weighting, spatial aggrega-tion and SES-standardization at municipal level. The relevant variables for the three study areas were overlaid and their statistical relationships examined using spatial regression and Analysis of Variance (ANOVA) models. Some correlations between particulate matter concentrations and SES variables were significant but weak in magnitude, without clear trends and not fully con-sistent across the study areas. Overall, the data thus did not allow for a reliable differentiation of PM2.5 exposure as the variables with country-wide coverage offered only limited information on the population’s SES. The household income variable was considered to be a meaningful indica-tor for SES but its spatial resolution was too coarse to depict fine-scale variations. Residential rent and purchase price indices on the other hand had an appropriate spatial resolution but represented SES only in approximation. In order to differentiate exposure to particulate matter by SES in Germany, future studies would require nationwide datasets with finer spatial resolutions.Publicationtype: Research Report176 - Some of the metrics are blocked by yourconsent settings
