Transforming Accra towards a Sustainable Future: Comprehensive Land Use Planning and the Greater Accra Urban Simulation System (GAUSS)

Frazier, Tyler J. (2011-04)

The urbanization of Sub-Saharan Africa is occurring more rapidly than in any other region in the world, at a historically unprecedented absolute rate of increase, within an institutional framework desperately lacking in resources. In step with its Sub-Saharan location, Ghana is experiencing unprecedented urbanization with currently 50% of its 23 million people living in urban areas; that share ...

The Impact of Demographic Change on the Accessibility to Public Services for the Elderly on Children of Hannover, Germany

López Covaleda, Helber Y. ; Frazier, Tyler J. (2011-11)

Late in 2009, the German government conducted an exercise to determine population trends for the next 50 years. This study indicated that the German population, which is approximately 82 million, is expected to decrease by 12 to 17 million people as well as experience a significant shift in its demographic profile (Statitistisches Bundesamt, 2009). The most significant finding from this exercis...

Pricing local emission exposure of road traffic: An agent-based approach

Kickhöfer, Benjamin ; Kern, Julia (2015-05-16)

This paper proposes a new approach to iteratively calculate local air pollution exposure tolls in large-scale urban settings by taking the exposure times and locations of individuals into consideration. It explicitly avoids detailed air pollution concentration calculations and is therefore characterized by little data requirements, reasonable computation times for iterative calculations, and op...

The correlation of externalities in marginal cost pricing: lessons learned from a real-world case study

Agarwal, Amit ; Kickhöfer, Benjamin (2016-12-22)

Negative externalities cause inefficiencies in the allocation of capacities and resources in a transport system. Marginal social cost pricing allows to correct for these inefficiencies in a simulation environment and to derive real-world policy recommendations. In this context, it has been shown for analytical models considering more than one externality, that the correlation between the extern...

Is marginal emission cost pricing enough to comply with the EU CO2 reduction targets?

Kickhöfer, Benjamin ; Agarwal, Amit (2015-09)

From transport economic literature it is known that pricing (environmental) externalities can improve the efficiency of a transport system. However, in real-world politics, policy setting often follows so-called `backcasting' approaches where predefined goals are set, and policy measures are implemented to reach those goals. This study presents, for a specific case study, an parametric approach...

On the Deterministic Prediction of Water Waves

Klein, Marco ; Dudek, Matthias ; Clauss, Günther F. ; Ehlers, Sören ; Behrendt, Jasper ; Hoffmann, Norbert ; Onorato, Miguel (2020-01-07)

This paper discusses the potential of deterministic wave prediction as one basic module for decision support of offshore operations. Therefore, methods of different complexity—the linear wave solution, the non-linear Schrödinger equation (NLSE) of two different orders and the high-order spectral method (HOSM)—are presented in terms of applicability and limitations of use. For this purpose, irre...

Electrification of Urban Freight Transport - a Case Study of the Food Retailing Industry

Martins-Turner, Kai ; Grahle, Alexander ; Nagel, Kai ; Göhlich, Dietmar (2020-04-14)

Decarbonisation is a major challenge for the coming decades, for all industries, including the transport sector. Battery electric vehicles are a potential solution for the transport sector to reduce its carbon impact. Asides from the question whether there is sufficient supply of electric vehicles for freight transport, it is also unclear whether battery-powered trucks meet the practical requir...

Mobility traces and spreading of COVID-19

Müller, Sebastian Alexander ; Balmer, Michael ; Neumann, Andreas ; Nagel, Kai (2020-03-20)

We use human mobility models, for which we are experts, and attach a virus infection dynamics to it, for which we are not experts but have taken it from the literature, including recent publications. This results in a virus spreading dynamics model. The results should be verified, but because of the current time pressure, we publish them in their current state. Recommendations for improvement ...

Barrierefreie Taxis für Berlin: Bedarfsermittlung und Abschätzung der Flottengröße

Bischoff, Joschka ; Maciejewski, Michał ; Nagel, Kai (2017-04-28)

Die Berliner Taxiflotte weist aktuell nur eine geringe Anzahl an barrierefreien Fahrzeugen auf, welche von RollstuhlfahrerInnen genutzt werden können, ohne den Rollstuhl zu verlassen. In diesem Kurzpapier wird anhand eines Simulationsmodells untersucht, wie viele Fahrzeuge der stadtweiten Taxiflotte mindestens barrierefrei zugänglich sein müssten. Dafür wird zunächst eine Abschätzung der Nachfr...

The effect of unexpected disruptions and information times on public transport passengers: a simulation study

Müller, Sebastian Alexander ; Leich, Gregor ; Nagel, Kai (2020)

This paper deals with the simulation of unexpected disruptions in public transport in the agent-based transport simulation framework of MATSim. A replanning logic for public transport passengers is implemented so passengers can be informed about and react to a disruption and use an alternative route. An unexpected disruption of an underground line in Berlin is simulated to analyze how passenger...

The impact of pricing and service area design on the modal shift towards demand responsive transit

Kaddoura, Ihab ; Leich, Gregor ; Nagel, Kai (2020)

In this study, an agent-based transport simulation is used to look into different design concepts for demand responsive transit (DRT). In different simulation experiments for a real-world case study of the Greater Berlin area, the DRT service area is either set to the inner-city center area or the entire city area, and the DRT pricing scheme is varied. The existing simulation framework is exten...

Impact assessment of autonomous DRT systems

Bischoff, Joschka ; Führer, Karoline ; Maciejewski, Michał (2019-11-28)

The market entrance of shared autonomous vehicles (SAV) may have disruptive effects on current transport systems and may lead to their total transformation. For many small and medium-sized cities, a full replacement of public transport services by these systems seems to be possible. For a transport system operator, such a system requires a bigger fleet of vehicles than before, however, vehicles...

Márquez-Fernández, Francisco J. ; Bischoff, Joschka ; Domingues-Olavarría, Gabriel ; Alaküla, Mats (2019-08-08)

Over the last two decades, electrification has gained importance as a means to decarbonise the transport sector. As the number of Electric Vehicles (EVs)increases, it is important to consider broader system aspects as well, especially when deciding the type, coverage, size and location of the charging infrastructure required. In this article, a Multi-Agent model depicting long distance transpor...

Integrated Transport Planning: From Supply- to Demand-Oriented Planning. Considering the Benefits

Schwedes, Oliver ; Hoor, Maximilian (2019-10-24)

The idea of integrated transport planning is widely accepted in the research community as well as in the field of transport policy. However, the actual implementation is still lagging behind. Acknowledging the gap between concept and reality, the benefits of a demand-oriented approach have to be reconsidered by the various stakeholders in politics, the economy, planning and civil society. In or...

Using MATSim as a Component in Dynamic Agent-Based Micro-Simulations

Singh, Dhirendra ; Padgham, Lin ; Nagel, Kai (2019-05-13)

This paper discusses use of the widely used transport simulator, MATSim, as one component in a large complex agent based microsimulation where dynamic changes in the environment require the agents to be reactive as well as goal directed. We describe a number of refinements to MATSim that have been made to facilitate its use within our deployed wildfire evacuation applications, as well as some t...
