Traffic Management
Included in this category are all activities within the traffic management area
including traffic signal control, freeway, and incident management. Table 3.4
lists data that could be generated from these sources, representing a sample of
data possibilities within traffic management. A more complete catalog is avail-
able in the form of the Traffic Management Data Dictionary [11].

Traveler Information
Traveler information involves collecting data about the transportation system
and converting it into information that can be delivered in a timely manner to
travelers. The overall concept is to improve travel decision-making through the
delivery of decision quality information. Traveler information can be delivered
through multiple channels including the web and in vehicle information sys-
tems. Table 3.5 summarizes data that could be sourced from a traveler informa-
tion system.
