Providing modern, safe, and dependable transportation and mass transit services increasingly relies on intelligent transportation systems (ITS) such as telematics, centralized control systems, public information displays, public safety, incident management, and facilities security (e.g. CCTV). Virtually all ITS and similar systems used worldwide today to operate our roads, ports, airports, buses, and railways over any wide area rely on a robust, reliable, and secure communications infrastructure. In fact, the National ITS Architecture model itself requires land-based and wireless carriage for nearly every one of its technologies represented. This discipline is served by many of the same personnel who also perform services for our large public safety portfolio.
