| Summary: | The fundamental role of transportation is conventionally regarded as moving people from spatially separated activities; therefore, travel behaviour analysis relies on the premise of derived travel demand. However, the spectrum of enroute activity has witnessed dramatic changes due to technological breakthroughs. We argue the conventional assumption of total negativity in travel utility needs to be revised based on a systematic investigation of travel-based multitasking behaviour. To achieve this, we first produced a travel-based multitasking typology by synthesising all types of in-vehicle activities to establish the evolving behavioural patterns. To understand people’s behavioural motivations for multitasking during travel, we proposed and validated a theoretical framework whereby effects of multitasking habit and smart device addiction are identified. People’s travel time/ cost perception and autonomous vehicle adoption are found to vary across different levels of being a multitasker (i.e., strength in travel-based multitasking habit) or screen addict (i.e., strength in smart device addiction). |
