9 The ITS-4 Technologies ± The ability to sense the presence and identity of vehicles or shipments in real-time on the infrastructure through roadside devices or Global Positioning Systems (GPS); ± The ability to communicate (i.e., transmit) large amounts of information cheaper and more reliably; ± The ability to process large amounts of information through advanced information technology; and ± The ability to use this information properly and in real- time in order to achieve better transportation network operations. We use algorithms and mathematical methods to develop strategies for network control and optimization.
