Verständnis der raumzeitlichen Reisezwecke der urbanen Mikromobilität aus der Perspektive des docklosen Teilens von E-Scootern
In den letzten zwei Jahren haben wir das immer schnellere Wachstum von Mikromobilitätsdiensten (z. B. E-Bikes und E-Scooter) miterlebt, das sowohl Herausforderungen als auch neue Möglichkeiten für die traditionellen städtischen Verkehrssysteme mit sich bringt. Beispielsweise bieten Mikromobilitätsdienste aufgrund ihres Komforts, … Read More
Räumliche Daten für die Gesellschaft – HeiGIT in die Zukunft geführt
Unterführungen, Treppen und hohe Bordsteinkanten sind für Menschen mit Gehbeeinträchtigungen eine große Herausforderung. Ein maßgeschneiderter Routenplaner kann aber ihre Mobilität erhöhen, indem er Wege mit möglichst wenigen Hindernissen berechnet.
