Summary
This project aims to advance the understanding of multi-tasking while travelling and how this affects the value of travel time. The traditional approach in travel behaviour research (until the early 2000s) has assumed that the time spent travelling is something that people are undoubtedly aiming to reduce, as they perceive it as unproductive and preventing them to perform other activities: in other words, wasted time. This assumption is based on the behaviour of a lone driver who is entirely focused on the task of driving, but seems unrealistic when thinking about public transport passengers and, even, more, future users of autonomous vehicles. Indeed, many studies have now shown that this view conflicts with the reality that most people conduct activities while they travel: people work, read or sleep on the train and bus, listen to music and talk on the phone while driving, and so on. The diffusion of increasingly advanced portable technological devices such as smartphones and laptops has made this phenomenon even more widespread, leading policy-makers to ask key questions about what people do while they travel, if their ability to multitask enhances their travel experience and satisfaction, and, fundamentally, if it affects their value of time. The latter is a key policy measure capturing the monetary value that travellers attribute to reducing the time they spend travelling. There is currently limited evidence about how the value of time spent travelling changes when people are conducting activities, and the existing evidence is largely limited to rail travel. The understanding of people multitasking behaviour and how this affects their value of time is also key in the face of emerging mobility tools such as autonomous vehicles, rideshare and urban air mobility.
While the specific policy questions might vary across modes and purposes, the present project aims to adopt a comprehensive approach considering multitasking across modes (including active modes, driving, public transport and potentially emerging modes) and purposes. A particularly developed area of work is around the value of business travel time, and specific work can address questions in this area, if it is of interest to the student.
Against this backdrop, this project aims to:
- Exploit existing data as well as conducting new data collection to unveil what activities people conduct while travelling with different modes, including less-explored modes such as air and active travel.
- Develop advanced models to incorporate behavioural complexity related to multitasking behaviour, e.g. heterogeneity, endogeneity and layered activities (additional levels of multitasking).
- Calculate the value of time in different circumstances related to multitasking while travelling with different modes.
- Produce policy recommendations with the potential to impact large-scale value of time studies.
The project will allow the student to learn to work with existing data sources as well as conduct new data collection. They will have access to high-quality training in choice modelling and work with advanced models. If interesting for the student, international comparisons can be incorporated in the project.
