use of analytics has the potential to revolutionize transportation, by provid-
ing deeper insights and greater understanding than we have ever been able to
achieve. The converging availability of big data, suitable analytic techniques,
and data can unleash the power of big data. This has the potential to provide
new insights and understanding regarding transportation supply and demand.
It is likely that the impact of analytics on transportation will be as great as that
of the Internet. In the same manner as we approach web services, however, care
must be taken if the best results are to be achieved.
This chapter discusses the nature of analytics by providing an overview of
analytics and an exploration of how analytics can be applied across the range
of smart city transportation services defined in Chapter 5. The chapter also
discusses analytical performance management for smart cities, explaining the
relative merits of KPIs and analytics. The chapter concludes with a discussion of
the relationship between analytics and data. This illustrates the power that can
be unlocked through the application of a combination of big data and analytics.

6.3 Chapter Word Cloud

The word cloud in Figure 6.1 provides an overview of the content of the chap-
ter by listing the most frequently used words, with the font size proportional
to the frequency of use of the word. As the word cloud provides some insight
into the characteristics of the chapter at a glance, it could be considered to be
an analytic. Section 6.6 discusses the use of analytics to characterize smart city
transportation services.
