The FCC has designated c-v2x signal priority as the standard for vehicle communication, phasing out dsrc systems within 12 months. The Emtrac priority management system enhances traffic signal priority for transit and emergency vehicles, ensuring quick response times and reducing accident risks. It efficiently integrates various wireless communication methods to improve the performance of traffic systems across North America.

The Federal Communications Commission recently answered a question that impacts US-based traffic,
first response, and transit agencies: Which of the proposed communications methods will be adopted to
serve vehicle-to-vehicle and vehicle-to-infrastructure communications, DSRC or C-V2X? In their
unanimous November 18th ruling, the FCC designated C-V2X Signal Priority (Cellular Vehicle-to-
Everything) as the technology standard for developing safety-related transportation and vehicular
communications. Existing DSRC communications systems will be required to cease operations in 12
months as its spectrum will be split between extended Wi-Fi and C-V2X.

Radio-based communications have opened the path for various other wireless methods, including cellular signal priority,
WiFi, and others (each with their own strengths and weaknesses). Additionally many transit vehicles are already
equipped with transit systems that include GPS positioning. And it’s not uncommon for a transit fleet to be made up of
vehicles with differing signal-priority technologies.

EMTRAC Priority Management System has been used throughout North America and ensures Bus Signal Priority and
Emergency Vehicle Priority. System helps first-response and transit vehicles get to their destination both quickly and
safely.
The evacuation route's entire planning is a critical part of emergency management and can greatly reduce the end of life
or harm to the citizens through unforeseen circumstances. The purpose of evacuation route planning is to reduce
evacuation time under certain limitations and lessen the likelihood of depth hazards to citizens from accident areas.

5. Emergency Vehicle Preemption Device
Read on as we discuss why is it essential to Implement Emergency Vehicle Preemption
5
Emergency vehicle preemption allows for a considerable reduction in response times. The system allows emergency
vehicles along the U.S. to pass through high-volume crossings quickly with fewer conflicts, saving few seconds per
intersection.
The system can reduce the number of emergency vehicle crashes - which is around an average of 2.3 crossing crashes
per year & less than one crossing crash every five years.
With reduced stoppages at signalized crossings, cities can reach the exact response times with fewer rescue and EMS
stations than would ordinarily be required, rendering notable cost savings.

Difference Between Traffic Signal Priority & Preemption
6
Today's blog would revolve around Transit Signal Priority and Traffic Signal Preemption and the primary difference
between the two.
The primary difference between Transit Signal Priority and Traffic Signal Preemption is that signal priority changes the
normal signal operation process to help transit vehicles better. The Emergency Vehicle Preemption limits the regular
process for rare cases such as countering the fire engine or nearing a train.
Transit Signal Priority (TSP) is a back-end plan that facilitates in-service transit vehicles, like cars or buses, through
traffic-signal controlled intersections.

The three-segment of a network-based TSP system are:

⦿Transit vehicle detection system
⦿Traffic signal control system
⦿Transit/traffic management center
The difference between TSP and Traffic Signal Preemption for Emergency Vehicles is that there is more reliable control
signal priority adjustment to the usual signal operation process for transit vehicles. At the same time, Preemption
obstructs the standard process for special events such as approaching trains or responding to fire engines.

Primarily, in most applications, traffic signal preemption is limited to emergency vehicles. Usually, a vehicle equipped with
a preemption device will use it when approaching a red signal to change the signal to green immediately. There is a
particular range of around 1500 feet for a mobile infrared transmitter.

10. Bus Signal Priority

Transit Signal Priority (TSP) is a Advanced Traffic and Bus signal Priority Management Systems or mechanism to provide
special treatment and reduce dwell time to transit vehicles such as bus, rapid transit vehicle, railroad car, water vehicle,
municipal vehicles, law enforcement and fire safety vehicle at signalized intersections.
Transit Signal Priority system requires some hardware equipment vehicle detectors and specialized traffic signal
controllers.

The Emtrac's Traffic Signal Preemption Devicemakes it more manageable and reliable for emergency vehicles to reach
residents in need by clearing the traffic ahead of them. It gives them green lights at intersections and makes all other
traffic securely to a stop.
It comes with three different parts -
⦿vehicle components,
⦿wayside components,
⦿and the software that configures and monitors the system.

EMTRAC System is considered as one of the best Traffic Priority Management System provides safe passage for
emergency and first response vehicles as well as reduces dwell time, ensure priority or preemption for municipal vehicles
and public transport vehicles by deploying traffic light preemption devices at intersection points.
The EMTRAC deploy Traffic Light Preemption Device at transit points that are managed by Priority Management
Software. EMTRAC Priority Management System consists of three major components.

Emergency Vehicle Preemption (EVP) Device : Driving cautiously on the road saves your life as well as others. The sudden
facing of an emergency vehicle can change the track of other vehicles as individual driver's maneuvers might get
confused and create conflicts that can cause emergency vehicle crashes or block lanes increasing response times.
Using Emergency Vehicle Preemption (EVP) to provide emergency vehicles a green light at crossings can lessen driver
distraction, needless conflicts and improve emergency response times.

16. Traffic Cabinet Monitor

Like a fleet of fighter jets, a traffic signal system must remain in a “state of readiness” with all critical functions operating
properly at all times. With the Traffic Cabinet Monitor system, both large and small cities can receive the real- time status
updates that are essential for continuous system readiness.
Workstation monitors can display current phase states for all equipped intersections, as well as a wide range of
detection-input and vehicle activity. This activity may be displayed on a single workstation monitor—or it may be
apportioned for display across a video wall.

A large part of an intelligent traffic system is knowing the current status of your traffic equipment—and being able to
respond to issues remotely whenever possible. The Traffic Signal Monitoring System allows traffic personnel to do just
that, whether the city has an advanced traffic management center or just a single workstation.
The Traffic Center system includes a number of service modules, each providing information for a different part of the
traffic system. These modules enables cities to efficiently increase their ITS capabilities by integrating the system in the
areas it’s needed most. Additional modules may then be added to expand ITS functions.
