Recent advances in global positioning systems (GPS) technology have resulted in a
transition in household travel survey methods to test the use of GPS units to record travel …

Where GPS technology can precisely register the spatiotemporal elements of activity-travel
behaviour, travel characteristics need to be imputed from the data. As such, throughout the …

In line with a growing interest in complementing surveys with tracking technologies, this
paper aims to explore what differences between perceived and real travel time can be found …

Multimodal integration is an important issue in public transport systems due to its influence
on both passenger experience and overall network efficiency. In most countries in the global …
