One of the most notable changes to cityscapes worldwide in the past 20 years has been the steady expansion of information and communications technologies (ICTs). Today, urban residents navigate cities with smartphones, track their own activities with digital devices, access public transportation systems with smart cards, and interact with governments through web portals. In urban planning, there is a growing interest in how ICTs may result in new knowledge about cities and be used to improve urban quality of life. Some researchers have begun to probe the burgeoning data sets these new ICTs produce in search of previously hidden patterns (e.g. Townsend, 2015; Bettencourt and West, 2010). For others, ICTs open the possibility of creating new ways to tackle longstanding urban problems; for example, smart city strategies utilizing new technologies to improve urban management (Batty et al., 2012; Goodspeed, 2014; Neirotti et al., 2014). Planning scholars are beginning to tap the new data sources to shed light on classic urban social science questions (e.g. Thakuriah et al., 2014). Finally, new technologies have fueled work by practitioners and scholars to tailor ICTs to support planning tasks with visualization, modeling, and analysis. This category of ICTs has been dubbed planning support systems (PSS) (Harris and Batty, 1993; Klosterman, 1997; Klosterman and Pettit, 2005; Geertman and Stillwell, 2004, 2009; Geertman et al., 2013, 2015).
