Emergency Routing
Emergency Routing

When emergencies occur, first responders must arrive quickly and safely to the scene. Smart traffic management uses congestion data and vehicle location to adapt routing and traffic signal timing to ensure emergency vehicles can arrive fast. Additionally, Digi FirstNet Ready™ cellular routers utilize Band 14 to deliver priority and pre-emptive communications for first responders.

Adaptive Control
Adaptive Control

Today, cities can be much more strategic in their implementation of traffic systems to manage their city congestion. Adaptive control adds the "smart" to smart traffic management. Using sensors, traffic cameras and fast, reliable cellular communications, adaptive control systems detect vehicle congestion, which triggers changes to traffic signal timing to optimize traffic throughput in real time.

Backhaul Communications
Backhaul Communications

A critical communications network for smart traffic management must include high quality, high availability backhaul communications between the communication hub, or "traffic management center" (TMC) and the components across the network. Digi provides guidance on establishing concurrent cellular and fiber links and other strategies for continuous, reliable communications with the TMC.

Connected Vehicle
Connected Vehicle

Connected vehicle technology is designed to prevent collisions between automobiles, transit systems and pedestrians. Municipalities are installing the critical infrastructure for this smart city strategy now. In doing so, they can take advantage of some of its key benefits. Digi can help you plan and deploy connected vehicle technology as part of your Intelligent Transportation Systems (ITS) and traffic management plan.

Public Transit
Public Transit

Smart traffic management systems are not only designed to route emergency vehicles, commuters and other city vehicle traffic, but they also integrate with the city public transit systems. Traffic signal timing is adjusted to maintain schedules of transit buses and light rail. These systems can be automated and managed by system administrators at the Traffic Management Center for optimal routing.

Simplified Infrastructure
Simplified Infrastructure

Traffic management systems today rely on a range of technologies, from analog lines to twisted pair, private radio and copper. Municipalities are moving to cellular networks for faster, more reliable, robust and cost-effective connectivity that can support the entire range of traffic systems from traffic cameras and routing applications to connected vehicle technology. Digi cellular solutions integrate them all.

Whether you are implementing an Intelligent Transportation Systems (ITS) solution, such as connected vehicle, or you are seeking the most effective way to route vehicles and emergency responders through your city, you will find resources to support your quest. Or contact us to start the conversation.

The number and variety of connectivity solutions in municipal traffic systems has increased over the years, from analog leased lines to twisted pair, fiber and wireless radio solutions, sometimes working concurrently. The management challenges and maintenance costs are enormous. But there is a better way.

What you'll learn in this webinar:

  • How cellular technology has transformed the traffic management landscape
  • The benefits of connecting traffic systems anywhere, all the time, with one device
  • Applications on the horizon and how to future-proof traffic systems
  • Key considerations including cloud management and security when upgrading or scaling your system

Digi Support for Intelligent Transportation Systems

Product Family Versatility

Digi offers a range of network equipment for traffic and intelligent transportation systems, enabling department of transportation and municipal transit managers to consolidate infrastructure, reduce overhead and improve efficiency.

  • Cellular Routers - The Digi cellular router family includes high-capacity dual-SIM routers for mission-critical networks, as well as mid-range and light duty single-application routers.
  • Power Supplies - Digi supplies industrial-grade customized power supplies for powering cameras and other accessories, in addition to the router.
  • 900 MHz Modems - Used to connect serial equipment around the intersection or adjacent intersections.
  • Serial Servers - Enables administrators to bridge legacy serial devices onto modern IP-based networks.
  • Device Management - Digi Remote Manager®, Digi’s cloud-based device monitoring, management and security platform, enables efficient and effective network operations.

Automated Network Security

Digi’s system-level security architecture uses PKI, IPsec and SCEP to establish a very high defense against cyber-attacks with low operational cost. It uses open system authentication protocols enabling use of multi-vendor data center equipment, unlike similar competitor offerings.


Digi Remote Manager (Digi RM) retains a full copy of the router configuration when deployed, which simplifies both the initial installation and any replacement. This feature improves maintenance efficiency, as site personnel do not need configuration training or laptops. It also increases network reliability and availability, as there are fewer configuration errors.

Link Performance Measurement

Digi RM provides detailed and continuous latency and availability performance metrics for every communication link from the dashboard, and provides reports for offline analysis. Administrators can perform speeds tests to evaluate peak throughput at any time using industry standard iperf, providing visibility into network performance for quick detection and resolution of any network trouble.

Proximity Services Enabler

Digi routers include Bluetooth, which has expanded into greater IoT use, most notably for MAC capture used by smart city analytics platforms. Any of the Wi-Fi interfaces can be configured for MAC capture as well.

Industry Ratings

Products are available that meet the industry standard TS2 specification. Mounting accessories include DIN rail brackets.
