The SONEM 2000 stands as a leading-edge solution in traffic signal prioritization technology, tailored for urban environments. Installed across British Columbia and Yukon, this system excels in detecting emergency vehicle sirens with exceptional precision, allowing for accurate determination of their approach direction.

It promptly alerts traffic controllers, ensuring emergency vehicles receive expedited passage through intersections when urgently needed. Moreover, the SONEM 2000 seamlessly integrates into existing traffic management infrastructures. It automates the initiation and clearance of priority requests, optimizing traffic flow and minimizing delays once emergency vehicles have safely passed through intersections. Engineered to meet stringent reliability and performance standards, the SONEM 2000 plays a crucial role in enhancing urban safety and operational efficiency, contributing to improved emergency response times and overall city mobility.

The SONEM 2000 enhances signal priority for emergency vehicles by detecting every approaching emergency vehicle siren through sound.

Functions:

• Direction Determination: Accurately determines the direction from which the emergency vehicle is approaching.
• Traffic Controller Notification: Notifies the traffic controller to grant priority to the approaching emergency vehicle, requesting a green light in its direction of travel while holding all other directions and pedestrian signals on red.
• Automatic Priority Clearance: After the emergency vehicle passes through the intersection, the system automatically clears the priority request, allowing normal traffic flow to resume.

Deployment:

The SONEM 2000 is easy to deploy and requires minimal setup and configuration. Once installed, it operates hassle-free without the need for frequent maintenance, such as lens cleaning, and at a lower cost compared to retrofitting vehicles.

Advantages:

• Liability Control: Reduces or eliminates motor vehicle accidents (MVAs) involving emergency vehicles, civilian vehicles, and pedestrians at intersections.
• Cost Savings: Emergency Vehicle PreEmption can lead to cost savings in fire/rescue and EMS planning. Faster response times may reduce overall operational costs, and some studies have shown decreased crash rates after implementing EVP
• Improved Response Time: Emergency Vehicle PreEmption allows emergency vehicles (such as police, fire, and EMS) to reach incidents faster by reducing delays at intersections.
• Windows-Based Software: User-friendly interface for system management.
• Flash Memory: Enables data and software uploads/downloads via PC or modem.
• Real-Time Graphic Displays: Provides visual data on siren frequency, sound pressure levels (dB), and cycle rates.
• Siren Profiling: Determines compliance with "Class A" standards, Federal Regulations, and State Statutes.

System Overview:

The SONEM 2000 system detects approved electronic emergency sirens, activating the traffic priority request. Optional Verification Lights provide visual confirmation of system activation. The Visual Verification lights show a blinkiing white light which indicates to the driver/spotter that they have dedicated Preemption while the other 3 directions blink blue telling other emergency vehicles to be extra cautious entering the intersection, as preemption in another direction has been triggered.

It is essential for all personnel driving vehicles equipped with audible or visual warning devices during emergency responses.

Remember that Emergency Vehicle Preemption is not just about protecting emergency responders; it also benefits the community by ensuring timely assistance during emergencies. If you need more information or have any other questions, feel free to ask!
