Enhancing Traffic Safety with Traffic Light Preemption Systems

Traffic light preemption systems play a critical role in modern traffic management by allowing operators to override standard traffic light operations, particularly in the path of emergency vehicles. This technology significantly reduces response times, enhances traffic safety, and improves overall efficiency in urban areas.

Key Impacts of Traffic Light Preemption Devices:

Swift Emergency Response:
Preemption systems prioritize emergency vehicles, enabling them to navigate intersections swiftly and safely. Studies have shown a notable decrease in response times, ranging from 15 to 50 percent, resulting in more efficient emergency medical services and improved outcomes for medical emergencies.

Reduction in Emergency Vehicle Crashes:
Implementation of preemption systems has led to a significant reduction, up to 75 percent, in crashes involving emergency vehicles.
By minimizing the risk of collisions at intersections, preemption devices contribute to enhanced traffic safety and reduced property damage.

Versatile Applications:
Preemption technology extends beyond emergency vehicles, benefiting public transportation systems such as light rail, trams, and bus rapid transit systems.
Railroad systems also utilize Traffic Light Preemption Device at crossings to prevent collisions and ensure the safety of passengers and pedestrians.

Remote Operation and Integration:
Preemption devices can be remotely operated from permanent locations, such as fire stations or transportation network management centers.
Integration with emergency call dispatch systems further enhances the efficiency of emergency response operations.


Emtrac Systems has been at the forefront of implementing preemption systems across North America for over 25 years. Their solutions have helped first-response and transit vehicles reach their destinations quickly and safely. For inquiries or further information,

Optimizing Traffic Flow: The Impact of a Traffic Light Preemption Device

Image
Preemption systems can decrease response times for emergency vehicles. Various studies have calculated a 15 to 50 percent depletion in response times and a 70 percent decrease in emergency vehicle crashes. These changes drastically affect the results of medical emergencies and have considerably improved traffic safety. Traffic light/signal preemption is used in many places in the cities. It is a method in which traffic lights can be adjusted and fitted with unique infrared receiving gadgets when the signal is sent from a particular transmitter in a vehicle. Traffic light preemption device are utilized in different ways as they can be placed on-road vehicles and operated through remote control from a fixed location, such as a fire station, that can be joined with train-transportation Network Management Systems or through an emergency call dispatcher. Ideally, a traffic signal should be ready to receive a traffic preemption signal; if it is not prepared, it will not identify any act

Advanced Traffic Light Preemption Device for Reliable and Efficient Intersection Management

Image
The EMTRAC system, a cutting-edge traffic light preemption device , has been a pioneer in intelligent transportation solutions for over 30 years. Utilizing precise GNSS technology and secure wireless communication, the EMTRAC system ensures that traffic light preemption is reliable, safe, and efficient, revolutionizing how emergency and transit vehicles navigate through intersections. A traffic light preemption device is essential for emergency response and public transit systems. The EMTRAC system enables emergency vehicles—such as ambulances, fire trucks, and police cars—to receive a green light at intersections, significantly reducing response times and improving public safety. By facilitating swift and unobstructed passage through traffic, the EMTRAC system helps save lives and enhances the overall effectiveness of emergency services. EMTRAC-equipped vehicles continuously monitor real-time conditions to determine if traffic light preemption is necessary. When required, the system a

Efficiency in Motion: Enhancing Urban Mobility with Transit Signal Priority Systems

Image
  Transit Signal Priority (TSP) helps in making use of existing vehicle location and wireless communication technology to extend the green light of a traffic signal in allowing a Pace bus or CTA help to reduce travel times ensure arrivals on time and proceed with an intersection when the bus is way behind schedule. While discussing Transit Signal Priority, the basic reality is that using Preemption and Priority settings for traffic signals can change the signal timing and prioritize certain types of vehicles such as emergency vehicles, trucks, buses, or trains. This system aims to speed up travel times, helps improve safety, and provides a way for priority vehicles to arrive at their next destination. More than 50 percent of the area’s transit riders can take benefit of faster, more dependent on bus service. On Transit Signal Priority equipped buses, riders will see remarkably lesser traffic signal delays, allowing them to reach their destinations on time—with lesser interruption
