The Glasgow Mobility App Survey (GlaMAS) is a cross-sectional survey based on a sample of the general adult population living in private residences across the Glasgow city region. The data collection aimed to capture information about individuals' travel behaviour through three methods. First, the researchers conducted a household survey to get information on socio-demographic characteristics and travel-related attitudes and behaviours. Second, each participant was asked to install TravelAI's 'MyWays' app on their mobile phone. The app automatically tracks the locations of individuals, detects stops, and estimates the mode of travel. Third, participants were asked to complete a one-day travel diary administered through the 'MyWays' app so that this could be compared to the automatically-detected travel records. The household survey collected data relating to:family type, household income, etc., to allow understanding of the socio-economic background of the householdindividual's patterns of activity and mobilityvalues, attitudes, and perceptions towards different modes of travel relating to behaviours and daily activityinformal competencies, like numeracy, IT skills, etc.work patterns, including work from home informationimpact of COVID-19 on attitudes and perceptions towards different modes of travelThe manual travel diary and automatic trip data from the 'MyWays' app aimed to investigate the following:the potential of smartphones for automatically producing a travel diarythe correspondence between the manual travel diary and the automatic travel diary
