Unique Needs of Traffic Management Systems
Traffic management is undergoing a massive evolution, as cities move to smart traffic management systems that gain more control, automate processes, obtain better insights into congestion and other problems across the city, and most importantly, ease traffic problems and improve emergency routing without widening city streets.
Smart traffic management systems require sophisticated communications that support applications such as adaptive control – improving upon scheduled and metered traffic light systems to better direct and control traffic automatically based on current conditions.
Today’s smart traffic management systems also must support public safety and disaster planning, ensuring that critical communications are always prioritized, that first responders can get accurate, real time information, and that in the event of a major disaster requiring evacuation or other emergency measures, the city is prepared.
These systems must integrate into existing traffic management infrastructure to control costs and facilitate rapid deployment, and enable the applications of the future, including Connected Vehicle – which will soon provide vehicle-to-intersection communications for automated emergency braking and improved safety on city streets. The TX54 is uniquely positioned to meet this needs of this market.
