The TxDOT video analytics demonstration system is designed to monitor traffic conditions by collecting data such as speed and counts, detecting incidents such as stopped vehicles and reporting such incidents to system administrators.
As illustrated in Fig. 1.1 there are three major components for a video analytics system: core computation unit, web server, and database server. The database server and web server cooperate to store and visualize that are provided through a web-based interface to the user. The interface bridges the communication gap between the operators in Traffic Management Center (TMC) and the data from the on-site processor.
If the system is assigned an internal/public IP address, it can be easily accessed via that IP address by computers within the same internal/public network. If the system is not assigned an IP address it is always possible to run the system offline via a local host (127.0.0.1). The TxDOT demo system is designed to work on both video clips and streaming video, however, when the system is not assigned an IP address (i.e., is offline) it can only process video clips previously stored in the system and the email alert to administrators is disabled.
Besides power, the system requires an Ethernet cable to connect the system to the internal/public internet.
