Without a second tier of analysis beyond standard digital video analytics any system will quickly become overrun with alerts and messages. By employing Behavioral Analytics as a secondary tier the MetroTech Net is able to digest hundreds of thousands of alerts, extrapolate the significance within the greater context of a corridor and provide traffic managers with actionable information.

Secondary analytics act as an expert system where fuzzy logic and probability distributions are taken into account to determine the meaning and impact of discrete events as they occur throughout the traffic system. Based on artificial intelligence, expert systems, autonomous agent technology, and the patented MetroTech Decision Framework; all aspects of the behavior within complex traffic systems is digested and presented to the TMC as patterns of activity and propensity.

This set of core services employs multi-dimensional mathematics for the purpose of recognizing the complex relationships between regions of space and time. At the heart of this mathematical approach to dimensional analysis is Region Connection Calculus (RCC.) RCC is a "point free geometry" and as such treats all spatial information as regions of space with relationships that span an infinite number of regions and sub-regions. Time too, as examined through the context of RCC, can be described as a collection of regions, each interrelated.

Only through intricate, yet elegant, mathematical calculations can such complexity be digested into substantial information arranged to support decisions within the TMC. As objects such as automobiles and pedestrians interact with these regions the system is able to quickly resolve the complex nature of discrete activities into a much larger context. It is this contextual differentiation of small, seemingly insignificant, events within the transportation system that allows for greater awareness of possible impacts and pressures on the system as a whole.

DVA events and alerts are queued by camera systems "at the edge" for processing by the secondary analytics system. Once consumed these events are processed by a decision framework where the greater context of the traffic network is taken into consideration. As traffic related decisions are made by the MetroTech Net larger events and alerts are extrapolated by the secondary behavioral analytics.

Each new event is categorized and labeled based on a discrete set of predefined rules and strategies. Once an event is established and all associated metadata is created an event bookmark is inserted into the video content management system via an advanced video management service interface. As events and alerts are aggregated by the MetroTech Net, all become available to geospatial maps, web portal applications, reporting services, other technology providers attached to the ESB, and human operators in the TMC.

Examples of secondary analytics include, but are not limited to, IntelliSection health, projected congestion sources, impact analysis, traffic routing recommendations, and overall impact on the corridor as a whole.

The secondary analytics engine operates as a software service accessible by other ITS components within the MetroTech Net. These services act as multi-threaded operations which use the ESB, DVA event message queue, and an enterprise database as sources of information for analysis.
