In the late 1960s, Torsten Hägerstrand introduced the conceptual
framework of time geography which can be deemed an elegant tool for analysing
individual movement in space and time. About a decade later, the auspicious
time-geographic research has gradually lost favour, mainly due to the
unavailability of robust geocomputational tools and the lack of georeferenced
individual-level travel data. It was only from the early 1990’s that new GIS‑based research gave
evidence of a resurgence in popularity of the field. From that time on, several
researchers have steadily been publishing work at the intersection of time
geography, disaggregate travel modelling, and GI-science. This paper is
motivated by the belief that CAD-systems could entail new opportunities for
time-geographic research for both geovisualisation and geocomputation. The
purpose of this paper is two-fold. First, the paper critically reviews some
issues of space-time implementations by pointing to influential contributions
of time-geographic research. These implementations are primarily concerned with
the operationalisation of Hägerstrand’s constructs, including, more
specifically, the determination of so-called space-time accessibility measures,
the representation of individual travel possibilities in a space‑time
aquarium, and the expansion of time geography to represent both physical and
virtual interaction. And second, it will be shown how CAD can offer new
potential for the analysis and geovisualization of travel patterns in space and
time. This will be illustrated using examples drawn from the authors’ recent
studies.
