An adaptive route choice model for integrated fixed and flexible transit systems

Leffler, David (author), Burghout, Wilco (author), Cats, O. (author), Jenelius, Erik (author)

Over the past decade, there has been a surge of interest in the application of agent-based simulation models to evaluate flexible transit solutions characterized by different degrees of short-term flexibility in routing and scheduling. A central modelling decision in the development is how one chooses to represent the mode- and route-choices...

Simulating the interference of seagoing and maintenance dredging processes

Sepehri, A. (author), Kirichek, Alex (author), van den Heuvel, Marcel (author), van Koningsveld, M. (author)

Abstract: Efficient port operations require minimizing turnaround time which is the total duration of a vessel's stay in the port and encompasses waiting, maneuvering, berthing, and de-berthing times. The turnaround time can be reduced by optimizing arrivals and departures, maximizing berth availability, facilitating cargo handling, and...

Designing demand responsive transport services in small-sized cities using an agent-based model

Calabrò, Giovanni (author), Le Pira, Michela (author), Giuffrida, Nadia (author), Inturri, Giuseppe (author), Ignaccolo, Matteo (author), Correia, Gonçalo (author)

This paper presents an agent-based model (ABM) to simulate and compare two different operation strategies of a public transport service in small-sized cities, namely a fixed-route transit (FRT) and a demand-responsive transport (DRT) service, under varying demand rates and supply configurations. The ABM builds upon a previous work by the...

Single cell variability of CRISPR-Cas interference and adaptation

McKenzie, R. (author), Keizer, Emma M. (author), Vink, J.N.A. (author), van Lopik, Jasper (author), Büke, F. (author), Kalkman, Vera (author), Fleck, Christian (author), Tans, S.J. (author), Brouns, S.J.J. (author)

While CRISPR-Cas defence mechanisms have been studied on a population level, their temporal dynamics and variability in individual cells have remained unknown. Using a microfluidic device, time-lapse microscopy and mathematical modelling, we studied invader clearance in Escherichia coli across multiple generations. We observed that CRISPR...

Urbanism and Geographic Crises: A Micro-Simulation Lens on Beirut

Termos, Ali (author), Yorke-Smith, N. (author)

At a geographical and strategic confluence, the ancient city of Beirut, Lebanon, has witnessed crises from natural and human causes over the centuries. The modern urban and peri-urban development is a result of neo-classical economics, laissez-faire regulations, and complex socio-political structures. This article considers the contemporary...

Discrimination between social groups: The influence of inclusiveness-enhancing mechanisms on trade

Jonker, C.M. (author), Murukannaiah, P.K. (author), Verwaart, D. (author)

The bargaining power of prosumers in a market can vary significantly. Participants can range from industrial participants to powerful and less powerful citizens. Existing trade mechanisms in such markets, e.g., in rural India’s energy trade market, show occurrences of discrimination, exclusion, and unfairness. We study how discrimination...

On the scalability of private and pooled on-demand services for urban mobility in Amsterdam

Narayan S., Jishnu (author), Cats, O. (author), van Oort, N. (author), Hoogendoorn, S.P. (author)

The emergence of on-demand transport services is set to change the mobility landscape in urban areas. This study investigates the potential scalability of an on-demand mobility system to substitute motorised trips performed by private cars and public transport in Amsterdam, The Netherlands. We adopt an agent-based simulation framework and...

Evaluating crowding in individual train cars using a dynamic transit assignment model

Peftitsi, Soumela (author), Jenelius, Erik (author), Cats, O. (author)

As travel demand grows in many cities around the world, overcrowding in public transport systems has become a major issue and has many negative effects for both users and operators. Measures to address on-board congestion span from large-scale strategic investments (e.g. increasing infrastructure capacity), through tactical planning (e.g....

Charging infrastructure roll-out strategies for large scale introduction of electric vehicles in urban areas: An agent-based simulation study

Wolbertus, R. (author), van den Hoed, Robert (author), Kroesen, M. (author), Chorus, C.G. (author)

On the eve of the large-scale introduction of electric vehicles, policy makers have to decide on how to organise a significant growth in charging infrastructure to meet demand. There is uncertainty about which charging deployment tactic to follow. The main issue is how many of charging stations, of which type, should be installed and where....

An Agent-Based Approach for the Planning of Distribution Grids as a Socio-Technical System

Cavalcante Siebert, L. (author), Aoki, Alexandre R (author), Lambert-Torres, Germano (author), Lambert-de-Andrada, Nelson (author), Paterakis, Nikolaos G. (author)

Recent developments, such as smart metering, distributed energy resources, microgrids, and energy storage, have led to an exponential increase in system complexity and have emphasized the need to include customer behavior and social and cultural backgrounds in planning activities. This paper analyzes how emergent behavior in electricity...

Simulation of adaptive user behavior with respect to noises in offices

Mittal, Divyae (author)

In recent time, there has been a rise in the number of coworking and activity-based working spaces. This increase has brought a high return to the real-estate developers but at the same time has compromised with occupant satisfaction. It brings an additional challenge for the architects and designer to look into the user-centred design for...

Informed decision-making on healthcare facility locations in expanding refugee camps: Researching the interplay between healthcare facility locations and refugee settlement behavior

Nering Bögel, Meyke (author)

In 2018, the number of forcibly displaced people all over the world was higher than ever before. More than a third of this group are refugees, often living in refugee camps.  NGOs try to deliver all necessary aid to these camps, while facing limited access and resources. Therefore, they want to optimize the results of the aid they deliver. The...

Integrated route choice and assignment model for fixed and flexible public transport systems

Narayan S., Jishnu (author), Cats, O. (author), van Oort, N. (author), Hoogendoorn, S.P. (author)

The recent technological innovations in various ICT platforms have given rise to innovative mobility solutions. Such systems could potentially address some of the inherent shortcomings of a line/schedule based public transport system. Previous studies either assumed that flexible on-demand services are used as an exclusive door-to-door...

A framework for the impact assessment of low discharges on the performance of inland waterway transport

Kievits, Servaas (author)

Inland waterway transport (IWT) is one of the three main modalities for inland transport of dry, liquid and containerized cargo. As IWT performs well on cost-competitiveness, environmental friendliness, and congestion-related issues, authorities strive to shift freight transport from road to water. Inland waterway connections, however, are...
