GEOG2001: Digital Geographies: Geospatial Data & Analysis Lecture 2, Semester 2, 2024 St. Lucia Campus 29/07/2024 Acknowledgement of Country The University of Queensland (UQ) acknowledges the Traditional Owners, the Turrbal and Jagera peoples, and their custodianship of the lands on which we meet. We pay our respects to their Ancestors and descendants, present and emerging, who continue cultural and spiritual connections to Country. We recognise their valuable contributions to Australian and global society. 2 Geographies of Everyday Mobility Why should we care about everyday mobility? Key concepts Geospatial knowledge Mobility data + Cases around the world Conclusion 3 1.47 billion 0.24 billion km 9.6 million 41Mt 11 million 4 Economic Impact ▪ Macroeconomic: Transport is linked to the total output of an economy, through direct employment, as well as supporting economic activities of other sectors (passengers and freights) ▪ Microeconomic: Transport links producers, consumers, and the distribution of goods and services. Transport is directly associated with household expenditure. FHWA (2012) Exploring the Relationship between Travel Demand and Economic Growth, Fig 1. ‘Total Auto and Truck VMT (trillions) and GDP (trillions of $2005), 1936-2011’ 5 Environmental Impact ▪ Transport accounts for a significant share of global carbon emission (17% - 25%, according to different studies/analyses). ▪ Road vehicles (cars, trucks, buses, and motorbikes) account for nearly ¾ of all carbon emission from transport (BBC, 2020). 6 Social Impact ▪ Transport equity: The distribution of transport benefit and cost (economic, environmental, social, etc.) must follow the principles of fairness and justice. ▪ Horizontal and vertical equity: Horizontal equity means people of similar needs and ability are treated similarly. Vertical equity means the more disadvantaged people should receive favourable treatment.

It usually covers a 24-hour day or multiples thereof. The record is taken down with precision and detail, identifying what people have done with explicit reference to exact amounts of time. It is usually presented chronologically through the day, beginning with the time that a person gets up in the morning.” Michelson (1973) Time assigned to Time assigned to non- Budget assigned to travel activities travel activities goods consumption Time use diary Characterise everyday mobility Time use (allocation) Four types of time: Paid work (contract time) Household/family care (committed time) Personal time Free time (travel) Robinson & Godbey (1997) Robinson & Godbey (1997, ‘Time for Life: The Surprising Ways Americans Use Their Time’, Chapter 1, Fig. 3) Australians’ time use (during the pandemic) The Time Use Survey (TUS), 2020 – 2021 Four types of time: Necessary activities (personal time) Contracted activities (contract time) Committed activities (committed time) Free time activities (free time) Australian Bureau of Statistics (ABS).

Juster & Stafford (1991, ‘The Allocation of Time: Empirical Findings, Behavioral Models, and Problems of Measurement’, J Econ Lit) Characterise everyday mobility Space-time Space-time Hägerstrand’s budget constraints time geography Space-time budget instruments extend Time geography views activities as occurring only time-use instruments by incorporating at specific locations for limited time periods. information on the spatial coordinates of Constraints that limit the ability of individuals to locations where activities take place. travel and participate in activities include: Hoeben et al. (2014) 1. Capability constraints: the person’s capabilities for trading time for space in movement (e.g., access to public transport) 2. Coupling constraints: the need to couple with others at particular locations for a given duration 3. Authority constraints: the ability of public or private authorities to restrict physical presence from some locations in space and time Contextualise time geography Space-time path Individual path: Follow the Bundle: When individual The time space: Past, sequence of movements in the paths are located at the same now, and future space-time continuum place and time Ellegård (2019, ‘Time geography in the global context’, Ch1, ‘The roots and diffusion of time-geography’, Fig.1.1. a – c ) Contextualise time geography Space-time path “Individual paths convey information about the individual’s activity space and the influence of fixed activities that comprise the anchor points of day-to-day existence. Collections of paths convey information on emergent space-time patterns and structures, such as bundles, projects, and space-time activity systems.” Miller (2004, ‘A measurement theory for time geography’) Miller (2004, ‘A measurement theory for time geography’, Geographical Analysis) Contextualise time geography Space-time path Contextualise time geography Space-time prism prism: It characterises the future space of opportunities for an individual.

How does yours compare?’, The Conversation) 22 Journey to work: Essence of everyday mobility A total of 30% of the 1 million people who are employed in Greater Brisbane work in Inner City. The figure on the left shows the largest daily commuting flows to the inner city from South, North, and West. Cooper & Corcoran (2018, ‘Journey to Work in Australia’, Australian Bureau of Statistics, Fig 5.) 23 JTW Interactive Map 24 30 Minute Accessibility to Job When normalised by population size, it is clear that Australian cities share similar car accessibility (to job) to American cities. Wu & Levinson (2021, ‘Towards the 30-minute city — how Australians’ commutes compare with cities overseas’, The Conversation) 25 30 Minute Accessibility to Job European and Chinese cities have comparably better public transport accessibility (to job) than Australian cities and American cities. Wu & Levinson (2021, ‘Towards the 30-minute city — how Australians’ commutes compare with cities overseas’, The Conversation) 26 30 Minute Accessibility to Job Again, in terms of active travel (cycling in this case), Chinese and European cities have much better bike accessibility (to job) than Australian and American cities.

What are the more sustainable mobility models in other parts of the world that Australia could learn from? In our own city/region, how could we start building a culture of active travel? A few words to describe how geography or your discipline of study can help? Now the floor is open. Please share your thoughts and questions! Reminders Please continuing to sign up for volunteer discussants for Lectures 5, 9, and 10! If you have not indicated your fieldtrip preference, please do so by the end of the day. On Wednesday’s prac sessions, I will sub Reyad as your demonstrator. 41 Thank you Dr Frank Zou Prof Jonathan Corcoran Mr Md Amjad Hossain Reyad 501 Chamberlain Building (35) 511 Chamberlain Building (35) [email protected] [email protected] [email protected]
