Understanding Opportunities With AI Cameras and LiDAR for Smart Road Infrastructure

As the Consumer Electronics Show (CES) in January sparked a new wave of autonomous vehicles (AVs) coming to the automotive market in the next few years, much focus as of late has been on the technology of these vehicles themselves.

However, the technology embedded in road infrastructure is also beginning to see more conversation between service providers and municipalities.

With advancements in artificial intelligence (AI) and 5G network connectivity, smart-road infrastructure technology offers the promise of being added to many different roads, bridges and other transit systems across the U.S. in hopes of improving real-time traffic analytics and tackling the most challenging road safety and traffic management problems.

One technology at the center of this discussion is on the present-day use of AI-enhanced cameras and tomorrow’s promise of LiDAR (light detection and ranging) technology.

AI Will Enhance Camera Sensing Performance

Today, there are hundreds of thousands of traffic cameras deployed in the U.S. alone, and even millions more when CCTV cameras are considered. They are mainly used for road monitoring and basic traffic management applications (e.g., loop emulation).

However, bringing the latest advancements of AI to these assets can immediately improve basic application performance and unlock more advanced software applications and use-cases.

AI and Machine Learning deliver superior sensing performance over traditional computer vision techniques found in legacy cameras. They enable more robust, flexible and accurate detection, tracking and classification of all road users with algorithms that can automatically adapt to various lighting and weather conditions.

In addition, they allow for predictive capabilities to better model road user movements and behaviors, and improve road safety. Agencies can immediately benefit from AI-enhanced cameras with applications such as road conflict detection and analysis, pedestrian crossing prediction and infrastructure sensing for AV deployments.

LiDAR Technology Cannot Fully Replace Cameras

LiDARs can provide complementary and sometimes overlapping value with cameras, however there are still several safety critical edge cases where LiDAR’s technology does not perform well (e.g., heavy rain and snow, granular classification), and where cameras have been proven to handle better.

Moreover, today’s LiDARs technology remains expensive to deploy at scale due to its high unit price and limited field of view. As an example, it would take multiple LiDARs at a hefty investment to be deployed in a single intersection, where just one 360° AI-camera can be a more cost-effective solution.

For many budget-focused communities, AI-cameras remain the proven technology of choice today. Over time, as the cost of LiDAR technology moderates, communities should evaluate augmenting their infrastructure with such sensors.

Eventually, Sensor Fusion Will Drive Strong Results

When the cost of LiDAR technology eventually sees an anticipated reduction, it will be viewed as a strong and viable addition to the AI-enhanced cameras that are being installed today.

Similar to autonomous vehicles, sensor fusion would be the go-to approach for smart infrastructure solutions and would allow to maximize the benefits of both technologies. See table below.

cameras vs lidar

The use of a cost-effective and performing AI-powered camera today, combined with the great potential of LiDAR in the coming years could help communities and municipalities achieve a win-win scenario today and tomorrow.

At the end of the day, the goal is clear in improving overall traffic flow and diminishing vehicle crashes and fatalities, but the technology and implementation strategy has to be right in doing so. The technology monitoring our roads needs to change too, thus calling for the consideration of AI-powered cameras today with the promise of LiDAR tomorrow.

Derq provides cities and fleets with a patented smart infrastructure platform powered by AI that helps them tackle the most challenging road safety and traffic management problems.

Evolv Technology, Pittsburgh Pirates Team Up for Fan-Friendly Ballpark Security

Image
WALTHAM, Mass.—Evolv Technology has announced its partnership with Major League Baseball’s Pittsburgh Pirates, adding to the growing list of Pittsburgh, Pa. venues that have teamed up with Evolv to help keep people safe, including the Pittsburgh Cultural Trust and Acrisure Stadium, home of the Pittsburgh Steelers. When the Pirates opened the gates at PNC Park for the 2023 MLB season in early April, all attending fans passed through Evolv’s state-of-the-art Evolv Express screening solution, which uses sensor technology with artificial intelligence (AI) to provide safer, more accurate threat detection at unprecedented volume and speed, the company states. Fans can now walk through without always having to stop or open bags, reducing long lines and allowing guests to make their way directly into the ballpark. “What continues to make PNC Park so special, aside from the physical design, is the total fan experience. That begins from the moment they walk up to our gates,” said Travis Willi

Minnesota AG Calls for Cancellation of Home Security Contracts for Alleged Fraud

STEARNS COUNTY, Minn. — Bring Me the News reports that Minnesota’s Attorney General, Keith Ellison, says he’s gotten consumers in Stearns County out of home security contracts after they were misled by a door-to-door salesman. According to the report, Ellison’s office announced that home security companies Skyline Security Management and Safe Home Security have agreed to their cancel contracts with customers in and around Stearns County who purchased their systems from door-to-door salesman Gary Harvey. “Door-to-door salesmen and their employers are in the business of trust-building,” Ellison said in a statement. “They know they need to have your trust to sell you their products, particularly expensive products like security systems that are supposed to keep your home safe. When that trust is betrayed, it’s emotionally and financially painful. I appreciate Skyline and Safe Home taking the right step in canceling these contracts while my office does what we can under the law to hold M
