About the Project

The transport sector is undergoing fast and profound transformations that open stimulating research questions. Solving them means to improve a big part of the lives of millions of people:

Statistics from the Department for Transport show that on average each person spends 370 hours a year travelling. The limitations due to the COVID-19 outbreak have put in front of everyone’s eyes how crucial mobility is for the quality of life of people and a thriving society. Travelling within and between cities follows increasingly complicated patterns that rely on a plethora means of transport, ranging from more traditional means like private cars and conventional forms of mass transport to more innovative but already established services like ride-hailing (e.g. Uber) and shared vehicles (car clubs but also shared bikes), to the emerging micro-mobility systems (the e-scooters are currently under trial in the UK). The business model of transport provision is evolving towards Mobility as a Service, in which transport services of different kinds are integrated and offered through an intelligent platform in a user-centric system.

Planning, operating, and evaluating mobility systems in such a dynamic and multifaceted environment requires a clear understanding of travel behaviour. In the past, such an understanding had to rely on surveys of limited scope and granularity. The diffusion of mobile apps has made it possible to collect large and rich datasets passively, thus increasing the information available to researchers, practitioners, operators, and decision-makers.

We have access to one of such datasets, collected from the users of an open-source mobile app for multi-modal information, OneBusAway. For each trip made by the participants in the study, the dataset includes information on origin and destination, means of transport and duration of each leg of the trip, and the interactions with the app itself (a detailed description of characteristics of the app and of the data it can collect is available here.

The dataset offers a unique opportunity for exciting research on travel decision-making. In your PhD, you can use the data either to understand how people make their travel choices (the trip and personal characteristics affecting the choices and their importance, the temporal evolution of the decisions, and the impact of real-time information on the decision -making process) or to predict the choices from the historical behaviour. Depending on your interests and skills, you can approach the problem using discrete choice modelling or artificial intelligence techniques or a mix of the two. You will develop your project in collaboration with our partner universities in the US and Japan.
