Figure 11.9 Assumed configuration for smart city transportation management system.

Seven elements have been identified: a smart phone apps subsystem, a
movement analytics subsystem, a transportation management data and analyt-
ics subsystem, a transit management data and analytics subsystem, a freeway
management center subsystem, a traffic signal management data and analyt-
ics subsystem, and a traveler information data and analytics subsystem. The
smart phone application would act as a user interface between travelers and the
traveler information and data analytics subsystem. This would provide travel-
ers with current traveler information and enable travelers to provide feedback
on prevailing transportation conditions. The movement analytics subsystem
would provide GPS-based data from cell phones to enable traveler origin and
destination and choice of mode to be determined. The traveler information
data and analytics subsystem consist of a hardware and software environment
that supports all functions to turn traveler information data into information
and to conduct analytics on the data. The transportation management subsys-
tem would act as a data source for the traveler information data and analyt-
ics subsystem, along with the transit, freeway, and traffic signal management
subsystems.
