van Gisbergen, Daan (author)
This thesis explores waiting and rebalancing strategies in urban waterborne transport, intending to improve the efficiency and operational performance of water transportation systems. The study is based on a review of the literature on waterborne transport and waiting and rebalancing strategies. This is followed by a case study where the found...

Fuel consumption during the taxi phase of flight can be reduced by using electric wheel propulsion instead of aircraft engines. Currently, this can be either done by having external trucks towing the aircraft from the gate to the runway, or by incorporating electric motors on the aircraft wheels to power the aircraft without using the engines....

Segeren, Megan (author)
In this paper, the emissions mitigation potential of implementing operational towing at major European airports is evaluated. Using mixed-integer linear programming, a scenario simulating mixed taxiing operations is used to find the relationship between fixed vehicle costs and target emission savings at an airport and European level. Using...

Kamphof, Jorick (author)
Growth in air traffic demand and the increasing importance of reducing emissions cause airports to consider the improvement of their ground surface movement operations in terms of efficiency and environmental impact. Over the past years, engine-off taxiing techniques have been considered to reduce the environmental impact of airport taxiing...

The increased pressure to reduce aircraft emissions and the growing demand for air travel causes airports to consider alternatives for fuel-inefficient aircraft taxiing. External towing tugs can be deployed to effectively reduce on-ground fuel burn of outbound aircraft. These new operations are likely to aggravate ground delays as a result of...

In order to reduce aircraft emissions during on-ground operations, electric taxiing systems (ETS) have been intensively researched to take over or assist in part of the taxiing phase of a flight. One of these ETS is the TaxiBot, deployed by Smart Airport Systems (SAS). While a number of papers have been researching this vehicle routing problem ...

Electric taxiing (ET) is a novel concept that focuses on replacing engine-powered aircraft taxiing by taxiing using electrically powered towing vehicles, called ET vehicles. The main purpose of ET is reducing the impact of aviation on climate change while at the same time saving fuel costs. In this paper, we propose two models that can be used...

All major airport operators face a similar challenge, namely ensuring maximum throughput and maintaining high runway utilisation. A key part of this is accurately planning aircraft movements on the ground to avoid queueing and associated delays. A primary indicator of the operator performance in this area is the Taxi-Out Time. The research...

On-board electric motors can be used to drastically reduce the fuel usage during the taxiing phase of aircraft, leading to cost reductions for airlines and lower amounts of harmful emissions. This study analyses the current state of this innovation and its potential impact on aviation. On a global level, full adoption of electric aircraft...

An electric-recharging planning algorithm was developed in this study to accompany a dispatching algorithm that assigns real-time trip requests to vehicles of a shared taxi fleet owned by an operator. The algorithm decides on when, where, and how much each vehicle should charge, in real-time. It will also relocate idle vehicles if needed. The...

van Lingen, Wouter (author)
Demand for air traffic is growing worldwide. In order to accommodate this growth, existing infrastructure such as gates should be used more efficiently. One technique to increase gate utilization is by introducing gate pit-stops. Introducing gate pit-stops leads to additional towing movements which can potentially interfere with other traffic on...

van Baaren, Edzard (author)
Operational towing is a taxiing strategy to reduce the fuel consumption during the taxiing phase of a flight, which decreases the cost and environmental impact of taxiing. Currently, no operational electric towing systems are available that are fully electric, independent from the APU and are capable of towing both narrow- and wide-bodied...

Vaandrager, Willem (author)
In an increasing urbanizing world the need for efficient transportation methods is growing. Ridesharing, sharing a taxi trip with multiple passengers, has been proposed as an effective way to contribute towards solving the traffic problems that arise in city centers. Current solutions to the problem are often more focused on optimality, and a...

Capturing the individual’s behavioral responses to the actions driven by market and government will always be an interesting activity towards a broad spectrum of society. It could not be neglected that an individual may have different views in responding towards a new policy intervention or a new product market. However, references to use of the...

Decentralised air traffic control shifts decision making to a local level, allowing decentralised controllers to focus on solving local conflicts. Since decentralised controllers have accurate local information at their disposal, they can adapt quicker and more efficiently to changing conditions. Consequently, it is suggested that the dynamics...

The taxi procedure at an airport refers to the surface movement of the aircraft between the parking position and the runway or vice versa. Nowadays, aircraft tend to taxi with the main engines, even if they are not optimized for it. Using an alternative suitable taxiing system that fulfills the requirements of the taxi procedure could be a...

Growth in air traffic demand and increasing attention for environmental impact of the air travel industry and airports has spurred the innovation of the Electric Taxi System (ETS). The ETS incorporates an electric motor in the main or nose landing gear of an aircraft, powered by the auxiliary power unit (APU) of the aircraft. The system allows...

The goal of this research project was to develop and test an online, automated taxi movement planning tool, that optimizes the timed taxiing routes of all aircraft on an airport, by minimizing the impact on the environment. Automatic taxi planning tools have been developed before, but the emissions have never been included before as a factor in...

In de Amsterdamse straattaxi-industrie zijn vandaag de dag nog steeds verschillende problemen voor vooral de taxigebruiker te observeren: geweigerde korte ritjes, te hoge prijzen, ongehoord gedrag van chauffeurs. De dieperliggende oorzaken als informatieasymmetrie en marktmacht zorgen er uiteindelijk voor dat de consumenten de taxi negeren en...
