The EMTRAC system utilizes precise GNSS technology and secure wireless communication to provide reliable, safe, and efficient signal priority. The EMTRAC system has led the way for over 30 years—and it continues to lead the way with intelligent cloud-based centralized control.

The EMTRAC system is an intelligent system with both smart vehicles and intersections. It may be installed as a fully functioning cloud-based signal-management system, or it may be integrated with existing cloud systems to supplement conditional inputs.

Centralized Management

In most cases, cloud technology is utilized to allow for centralized control of traffic signals and vehicle signal priority.

The traditional method for handling Transit Signal Priority (TSP) has been though a distributed system, where the decision to grant signal priority is handled at each individual intersection. A common concern with non-EMTRAC distributed systems is they’re unable to handle all the various data inputs that should influence whether signal priority is granted or denied.

Centralized control through a cloud-based system enables traffic and transit agencies to evaluate any number of factors to ensure signal priority is granted when needed—and only when needed.

The end result being effective and efficient signaling, allowing for reliable transit headway.

EMTRAC Cloud Advantages

Network Icon

EMTRAC Module Access: The system natively integrates with other EMTRAC services, including Data Analytics, signal-state monitoring, cabinet monitoring, and Automatic Vehicle Location (AVL) monitoring.

Data Analytics Icon

Data Analytics: Recognize performance trends and identify needed improvements through detailed graphical activity displays.

Security: All data is encrypted, both in transit and at rest, and access control is as secure as on-premise storage. Data may be stored in any number of secure data centers to ensure accessibility at all times.

Conditional Signal Priority: Base signal-priority decisions on the most complete information available, including current vehicle, traffic, and traffic signaling conditions. Factor the decision on any number of variables.

Communications Reliability: Authorized personnel can securely access any of the EMTRAC services from any internet-equipped location, so they can view system activity and modify system settings when needed.

Accuracy: Vehicle units offer the most precise GNSS positioning available and are also equipped with dead reckoning for areas without satellite visibility (such as in tunnels and depressions).

Bus and Train Icon

Flexible Integration: The EMTRAC system may be installed as a full priority-management system, or it can be installed as a hybrid system integrated with third-party services.

Ribbon Icon

Experience: Most importantly, EMTRAC system capabilities are proven every day in cities across the globe.
