Technology is rapidly changing the transportation industry, and emergency vehicle preemption systems are no exception. Optical-based preemption technology is being replaced by new innovations, and the progress of change seems to be picking up speed.
As wireless and cellular communications grow, so will the sophistication of preemption systems. The next five years will see exponential advancements in connection and inter-connectivity.
New levels of connection
Emergency vehicles will be connected to, and interact with, the transportation infrastructure in new and unthought … Continue Reading
Preemption and priority systems provide emergency vehicles with green lights, so they arrive at the scene of an incident faster and more safely. While this technology has been in existence for a number of years, the Glance system from Applied Information utilizes a new generation of innovations to reduce arrival times while increasing safety. Here’s how the Glance preemption and priority system works.
The Glance system is fundamentally different from older radio-based or line-of-sight systems. The solution seamlessly … Continue Reading
When preemption meets connectivity, the result is not only a quicker route for emergency service vehicles, it means a safer one, too. While preemption and priority technology has continually evolved, the addition of a cellular connection is a game-changer for the traffic and transportation industry.
Cellular connection brings wide-spread benefits
Cellular connectivity not only allows you to pinpoint the location of an emergency vehicle, but it also offers the ability to clear traffic ahead of their arrival at the upcoming … Continue Reading
Preemption, in one form or another, has been in existence for 40+ years. It has transitioned from optically based to GPS and has included sirens, sound activated systems, and even switchboards that connect circuits across town. In all cases, these solutions address the challenge of getting emergency vehicles to the scene as quickly and as safely as possible.
When city leaders debate the installation of a preemption system, there are several things to consider while making a decision, especially if … Continue Reading
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
