Proving the value of analytics on the edge

By pushing more analytic capabilities where data is collected, organisations are achieving greater responsiveness and efficiency. Here are three edge analytics success stories.

Edge computing offers big potential advantages for companies in a variety of industries. This distributed computing model, which brings data storage and analytics closer to the sources of data, can offer organisations better response times, decreased network latency, reduced bandwidth costs, and even enhanced security.

Computing at the edge helps support initiatives such as the internet of things (IoT), by enabling remote processing of the data gathered by connected objects. Without such systems in place, the immense amount of data generated by connected devices would easily overwhelm an organisation’s central data infrastructure — or incur significant costs if shuttled to cloud repositories for analysis.

By pushing more analytic capabilities to the edge, where data is collected, organisations can achieve greater responsiveness and efficiency. Here are some examples of how organisations are deploying analytics at the edge for a variety of use cases.

Roadway safety

Trimble Transportation provides technologies such as routing and optimisation, tracking and visibility, and safety and compliance systems for its customers. Those clients, generally motor freight carriers, generate more than 10 billion data points each day from their in-cab telematics devices. That includes more than 50 variables such as engine temperature, turbo speed, oil pressure, velocity, and coolant levels.

An increasing number of vehicle sensors monitor key performance metrics and alert drivers to issues such as low tire pressure, lane departures, and back-up obstacles. While this has enabled many advances in safety technologies, it also generates a massive volume of data that needs to be processed quickly in order to be useful in real time.

For Trimble, edge analytics provides a way to deliver insights faster. The company, which is creating a connected supply chain by developing hardware and software for transportation and logistics companies, is building a hub-and-spoke network system where the back office of a trucking carrier is the “hub,” says Chris Orban, vice president of data science at Trimble.

The hub includes applications such as transportation management systems, order intake, safety and compliance, and other operational systems that rely on data provided by the “spokes,” Orban says.

“The spokes in this model are the truck drivers who use edge technology like onboard computers, electronic logging devices, and more in the cab while they’re on the road,” Orban says. “These devices are connected to the cloud via 4G LTE networks, and are performing many calculations on the edge. These calculations include tracking a driver’s hours of service, reporting on safety events, and scanning electronic documents such as proof of delivery.”

The company has been using some iteration of edge computing for years, Orban says, starting when the tracking of commercial vehicles became regulated. Trimble’s early electronic devices in the cabs of trucks relayed back simple information about where trucks were, as well as fuel levels, “providing communication to the back office during a time when we didn’t all have cell phones in our pockets,” he says.

The key business driver for this was the need for trucking companies to know where their assets were, and the ability to communicate with drivers and devices that might be outside of cellular coverage. “The devices had to function on the edge with drivers, because satellite communication might have been their only connectivity option,” Orban says.

From a safety standpoint, all of Trimble’s mobility devices interface between the engine control module (ECM) of a commercial truck and the company’s own and third-party safety tools to provide functions such as hard braking alerts, following distance warnings, and roll stability control notifications.

“In the cab, the driver can receive immediate feedback about their driving behavior and can modify it effectively in real time, or the device can do it for them,” Orban says. “For example, if they see that they are going around a curve too fast and the roll stability control triggers, that device can actually trigger the brakes and slow the truck down and bring it into a state where that roll stability control is not firing anymore.”

Trimble also offers edge applications for calculating a driver’s fatigue, based on their hours of service.

Another big area where Trimble is investing in its data analytics and edge computing capabilities is video. “Many commercial vehicles today have cameras installed in the truck, either pointed outwards or inwards on the dash, on the side mirrors, a reverse camera in the back, or all of these,” Orban says. “The amount of information that can be gleaned from these visual data sources is immense.”

Trimble’s Video Intelligence tool is triggered when a safety event occurs, such as a hard braking event where a driver slams on the brakes to avoid a collision. These videos can be used to mitigate risk for a driver, to prevent liability during an accident, or for driver training purposes.

“We’ve gone so far beyond the standard dash cam to a place where now we have truly integrated video systems that can help a driver with their work by looking down the side of the truck to give them lane departure warnings, help them properly position at a loading dock, and more,” Orban says.

Trimble’s data science team is deeply involved in its edge analytics offerings, Orban says. “Our team invests a great deal of time working directly with customers to understand their specific needs for their business,” he says.

Typically, as Trimble customers begin to apply safety systems, they see an incremental improvement over time. “Often, they will experience a 10% to 15% reduction in their drivers’ preventable accidents, as they apply different kinds of critical event warnings, such as hard brakes, roll stability control, and more,” Orban says. “Those sorts of edge solutions are literally changing the behavior of the driver who’s taking these actions.”

Traffic control

The City of Las Vegas is using edge computing, including an IoT deployment, for traffic control and to automate communications with autonomous vehicles.

“We are looking for ways to improve operational efficiency while providing benefits to the community,” says Michael Lee Sherwood, chief innovation officer in the city’s IT department. “Edge computing enables IoT systems to process critical data and provide real-time analytics and data.”

The traffic system, known as Blackjack, uses a platform supplied by Cisco that monitors traffic flow and provides real-time traffic statistics and capabilities for communicating with autonomous vehicles.  

Las Vegas began deploying edge computing technology in 2018 while working on smart traffic solutions. A key driver for analysing data at the network edge came from working with autonomous vehicle companies that needed near real-time data, Sherwood says.

“Edge computing allowed for data to be analysed and provided to the recipient in a manner which provided the best in speed,” Sherwood says.

Visualizing data in a real-time format “allows for decision-makers to make more informed decisions.”

The addition of predictive analytics and artificial intelligence (AI) is helping with decisions that are improving traffic flows, “and in the near future will have dramatic impacts on reducing traffic congestion and improving transit times and outcomes,” Sherwood says.
