Multimode technology allows complete interoperability between IR and GPS components. The Opticom™ Vehicle Control Unit (VCU) sends a signal to the Opticom™ GPS radio antenna or IR emitter, which then transmits the preemption request via 2.4GHz radio or infrared light to the Opticom™ intersection receiver/detector.
In this blended system, emergency and transit vehicles with different Opticom™ technologies seamlessly activate the preemption systems in their own or adjacent regions. This allows for a full GPS implementation while maintaining existing IR infrastructure. GTT and Advanced Traffic Products understand the importance of public budgets and offer solutions that protect previous investments while maximizing return on investment for the future.
