A selection of ITRL's ongoing master thesis projects
Designing public transport networks using big data
Designing public transport networks is a complex process with multiple goals, providing both basic accessibility as well as high capacity and fast travel, catering to both professional and leisure demand. At the moment most routes are designed using “know-how” of experienced planners, taking advantage of knowledge of the local environment and statistics from e.g. crowding.
However, with the rise of more data on both vehicle cost and travel demand, the opportunity for using “big data” to create optimized networks is possible. This thesis is a collaboration between ITRL, the division of Transport planning at KTH, Nobina and SL and aims to explore the possibilities of the latest research with real world data. The hope is to find new opportunities for reducing costs and creating public transport networks more suitable to traveler demand.
Integrating Autonomous Vehicles in a Financially Sustainable Business Model
Master Thesis within Industrial Engineering and Management.
Thesis Sponsor: Scania, Connected and Autonomous Solutions
Autonomous vehicles is one of the ongoing megatrends within the transport industry. With the technology in itself being in focus, business model innovation within the area is lagging behind. How will fully autonomous driverless vehicles be sold in the future? We are in the middle of a transformation and nobody knows for sure. With our Master Thesis we would like to explore and discover the full potential of this exciting technology when it comes to business models.
Design and analysis of an electric over-actuated vehicle suspension
ITRL have developed a Research Concept Vehicle (RCV) back in 2012 that is electric and that have an over-actuated suspension system meaning it can steer, camber, drive and brake individually on each wheel of the vehicle. It is now time to update the vehicle with a new design learning from the later versions of the RCV-E and creating a more dynamically capable platform to do more high dynamics tests with.
This aim of the thesis is to develop a new suspension system with integrated electric wheel motor, electric steering actuator, electric camber actuator and if possible active suspension.
The work tasks will consist of developing a new suspension concept for the old RCV vehicle including component search related to electric machines, gear boxes, active dampers, steering actuators and additional components such as bearings, bushings, joints etc. After the concept design phase to design a CAD model of the complete suspension for kinematic analysis as well as FEM analysis of custom components. The work also includes a design with manufacturability in mind.
Shared automation in control towers for automated vehicles
There are many potential situations when an automated vehicle will reach a state from which it cannot proceed without human intervention. This might be due to limitations in the vehicle’s authority, computational capacity or available information of the scene. With a traffic control tower these situations can be mitigated by remote human interaction. However, this is a daunting task for a human; operating or in other ways commanding the vehicle based on the remotely available sensor data. In many cases, though, the vehicle’s automation system will still be functional, and could be used to enhance the task of remote operation.
The aim of the thesis is to analyze and design a shared automation system where a vehicle is operated remotely in a safe manner in combination with onboard automation functions.
The thesis will revolve around investigating how compositions of spatial features affect the overall perceived complexity of the built environment. By measuring how people perceive different compositions, the purpose is trying to find KPIs that can be used to better understand how to design built environments with specific goals in mind. The complexity is important to know when controlling for background factors in perception studies related to driving/traffic in general. The work will involve mixed data collection methods, combining data from surveys with data from biometric sensors such as the ECG-straps.
Examining the potential of opening a new commuter train station in Fagersjö
Building new public transport infrastructure is an expensive investment requiring substanial economical resoruces and land use planning. We are examining if opening a commuter train station, on already existing commercial commuter train track, is a viable inexpensive alternative of increasing accesibility and mobility in an area.
As a case study we are applying this theory by adding a station in Fagersjö, a suburb in southern Stockholm, and examining the result through various simulations and analyses - including Cost Benefit Analysis (CBA). Furthermore, we are examining the possibility of housing development around the new station - and how that can affect the profitability of a new station.
Environmental impact assessment of different truck types
In order to design policies to meet the target to reduce operational emissions from the transport sector by 70% by 2030, it is important to consider the impact of new technologies. In the freight transport sector, an holistic assessment is needed to compare different truck types: the results of this thesis aim to help taking further decisions to support the agenda 2030.
The thesis aims to analyze the environmental impacts of electric truck (driverless and manual) in comparison to conventional diesel trucks (driverless and manual). The objectives are to analyze the different life cycles of these new trucks technologies compared to the conventional ones and find how other factors influence emissions of different truck types throughout their lifetime, taking into account both upstream and downstream processes. The scope of the thesis will be limited to Sweden, but international upstream supply chain will be considered while calculating the emissions.
