Savari leverages AWS Wavelength to make roads safer and more predictable

For the past decade, Savari has built in-vehicle, roadside, and cloud-based solutions for V2X (vehicle-to-everything) to help make the world’s roadways safer, smarter, and efficient. Increasingly, automotive leaders such as Ford and General Motors are announcing their support for V2X. Savari plays an important role in the V2X supply chain, providing the applications and underlying technologies used in testing and deployments across the United States. Looking forward, the V2X software supplied by Savari will power Advanced Driver Assistance Systems (ADAS) features on one in seven cars globally.

Savari’s V2X and Cellular-Vehicle-to-Everything (C-V2X) systems support a range of applications that require the ultra-low latencies enabled by AWS Wavelength at the edge of the 5G network. This helps make drivers aware of the latest road conditions so that they can make split-second decisions to prevent accidents. “AWS Wavelength provides our engineering teams with the infrastructure needed to address the challenges otherwise associated with conventional cloud products,” said Ravi Puvvala, CEO of Savari. “We aspire to further push the boundaries enabling use cases that were, in the past, not possible using conventional V2X technologies and the cloud.”

Savari V2X-equipped vehicles can advise drivers to maintain a safe distance between other vehicles, and provide alerts about emergency brake lights ahead, collisions, and blind spots. Additionally, Savari V2X technology enables vehicles to alert drivers about unexpected vehicle movement in intersections, vehicles making sudden lane changes, and do-not-pass lanes. By providing drivers heads-up notifications about road conditions, Savari V2X also helps increase safety. Examples of notifications include proximity of vehicles to infrastructures, speed warnings for sharp curves or work zones, and in-vehicle signal phase and timing visualization.

There are two features that set the Savari solution apart. First, Savari V2X software does not require line of sight to work, unlike traditional sensor technologies such as radar, lidar, and cameras, which can be compromised due to environmental conditions. As a result, Savari provides a reliable safety net that leads to greater driver awareness. Second, the high-bandwidth communication enables sensor data to exchange with other road entities such as cars and traffic lights up to a mile away. Being compliant with existing US and EU standards ensures there are no interoperability issues.

To support applications that provide warning information to drivers and pedestrians in near-real time, Savari leverages the ultra-low latency access to AWS compute and storage services enabled by AWS Wavelength at the Verizon 5G Edge.

“Using Savari edge APIs, any device or car subscribed to our suite of edge services can transmit telemetry data in near-real time. The availability of powerful compute resources on AWS Wavelength on the Verizon 5G network edge enables us to seamlessly run and scale backend applications that need to act on this data,” said Navin Katta, Cloud Director at Savari. “The applications serve a variety of purposes ranging from emergency response, to making highly dynamic maps available to autonomous vehicles. Some of the data can also be used for training deep learning models in autonomous vehicle stacks. As the market adoption of C-V2X increases in the coming years, the edge computing architecture is poised to play a major role in the way auto makers look at feature enhancement and updates to their cars.”

V2X in the past depended upon special hardware located inside the car, on pedestrians, and at street side to make it happen. “By taking advantage of the high reliability and low latency access to compute services made possible by Verizon’s 5G network and AWS Wavelength, Savari’s solutions can now run at the network’s edge,” said Paul Sakamoto, Chief Operating Officer for Savari. “This translates to hyper local deployments and potential cost savings for our customers. Moreover, our customers do not have to depend on specialized hardware anymore. Savari has used AWS Cloud products for over five years now, mostly for applications where subsecond latencies were acceptable. With AWS Wavelength, we are now able to deploy applications that have much less tolerance for latency.”
