Exploring the Impact of Traffic Light Preemption Devices

Traffic Light Preemption Devices are advanced systems designed to override normal traffic signal operations, granting priority to specific vehicles like emergency responders, light-rail systems, and bus rapid transit. These devices play a vital role in reducing response times and enhancing traffic safety by ensuring a clear path for priority vehicles through busy intersections.


For emergency vehicles, traffic light preemption significantly reduces response times by 15 to 50 percent while lowering crash rates by 70 to 75 percent. These improvements are crucial in medical emergencies and public safety situations, where every second counts. By halting conflicting traffic, preemption devices allow emergency vehicles to navigate intersections more efficiently, improving outcomes and minimizing risks.


The technology uses infrared receivers or similar gadgets installed at traffic signals. These systems are activated by transmitters in emergency vehicles or through remote control from fixed locations like fire stations or dispatch centers. Preemption signals ensure a smooth transition for priority vehicles, while intersections return to normal operation if no activation is detected.


Beyond emergency response, traffic light preemption devices also enhance efficiency in public transit systems, such as light-rail and bus rapid transit, and improve safety at railroad crossings by preventing collisions. For over 25 years, EMTRAC’s Traffic Light Preemption Devices have been helping first responders and transit systems across North America reach their destinations quickly and safely.

Improving Urban Mobility Using Traffic Signal Priority Systems

Image
Traffic Signal Priority (TSP) helps leverage a vehicle's current location and wireless communications technology to extend the green light of a traffic signal and allow a Pace or CTA bus to help reduce travel times and ensure on-time arrival and proceeding at an intersection when a bus is severely behind schedule. When looking at Transit Signal Priority , the basic reality is that using traffic signal priority and preemption settings can change signal timing and give priority to certain types of vehicles such as emergency vehicles, trucks, buses, or trains. This system aims to speed up travel times, help improve safety, and provide a way for priority vehicles to get to their next destination. More than 50 percent of area transit users can take advantage of faster, more reliable bus service. On buses equipped with signal priority, passengers will see significantly fewer delays at traffic signals, allowing them to reach their destinations on time, with less disruption to the over...

Enhancing Road Safety and Efficiency with Emergency Vehicle Preemption Systems

Image
In the realm of traffic management, ensuring the quick and safe passage of emergency vehicles is a top priority. When every second counts, traffic lights need to respond dynamically, allowing first responders to navigate roads without delays. Emtrac’s Emergency Vehicle Preemption system is designed to address this exact need, equipping intersections with smart controllers that grant priority access to emergency vehicles. This state-of-the-art solution not only improves response times but also minimizes potential accidents, making roads safer for everyone involved. Emergency vehicle preemption works by detecting approaching emergency vehicles and adjusting traffic lights accordingly. Emtrac’s system is particularly advanced, utilizing a combination of GPS technology, cellular communication, and signal priority algorithms to create a reliable and responsive preemption network. When emergency vehicles, such as ambulances or fire trucks, are en route to an incident, the system seamlessly ...

Enabling Emergency Vehicle Preemption for Safer and Faster Responses

Image
Emergency Vehicle Preemption (EVP) is a cutting-edge traffic management solution designed to enhance the safety and efficiency of emergency vehicles navigating through intersections. By overriding standard traffic signal timings, EVP ensures that emergency vehicles are granted a green light, allowing them to reach critical destinations quickly and securely. Key Benefits of Emergency Vehicle Preemption Enhanced Safety: EVP reduces the risk of collisions involving emergency vehicles at busy intersections by providing them with a clear and prioritized path. Improved Response Times: By minimizing delays, emergency vehicles can reach incident scenes more rapidly, supporting faster incident response and management. How Emergency Vehicle Preemption Works EVP systems combine advanced hardware and software to seamlessly manage traffic signals and clear the path for emergency vehicles. The system temporarily interrupts normal traffic signal patterns to prioritize the movement of emergency vehic...
