Traffic signal preemption requests are critical to ensuring that emergency vehicles are able to arrive on scene as fast as possible. These systems ensure that the traffic signals are prepared for the emergency vehicle and ensure safe passage through the intersection. In this video you’ll see a live demonstration of how the technology is working in Marietta, GA.… Continue Reading
Preemption systems are designed to automatically process a request for a green light as an emergency vehicle approaches a signalized intersection, so the emergency vehicle is given the right of way. This technology allows for faster response time and safer travel.
Most standard GPS preemption systems rely on a static, pre-set timing plan, which typically requests a green light 30 seconds prior to the arrival of the emergency vehicle at a traffic signal. The plans are based on distance, which … Continue Reading
Fire departments are continuously looking at ways to deliver emergency services more efficiently. In the past, the best solution for decreasing response time was to increase the number of fire stations and strategically locate them across the city. This entails building new stations, hiring more firefighters, and purchasing new equipment. While effective, this approach quickly adds up to a substantial investment.
Leveraging New Preemption Systems
Many cities and municipalities are turning to a new generation of preemption systems as a … Continue Reading
First-generation traffic preemption systems were primarily designed as optical-style systems. These solutions rely on sensors at each intersection being triggered by strobe light emitters on emergency and transit vehicles. While these initial types of installations were a step in the right direction, they offered little flexibility and came with a variety of challenges.
With advancements in technology, many cities, public safety, transit, and transportation departments are moving away from original, optical-based systems and to the new and more intelligent GPS-based … Continue Reading
